Blyth, ex Calamagrostis canadensis, # CSE5352, CNC5171857 (1♂) .</p><p>Hosts. Poaceae: Calamagrostis *canadensis (Michx.) P.Beauv., Dactylis glomerata L., Triticum aestivum L. (Spencer &amp; Steyskal 1986). Although this species is known from numerous grass genera in Europe, the only North American host record apart from those reported here is the series reared from T. aestivum in Ohio that was mentioned by Frick (1959, as A. nigripes Meigen). Since the citations given by Benavent-Corai et al. (2005) are incorrect for the prior records of both Calamagrostis and Dactylis, we note here that Pakalniškis (2000) reported A. albipennis from C. arundinacea (L.) Roth in Lithuania, and Robbins (1989) reported “ Dactylis ” as a host in England (where D. glomerata is the only species present).</p><p>Leaf mine. The egg is laid within a few mm of the leaf margin and the solitary larva forms a gradually widening, upper-surface mine, initially feeding toward the leaf apex and eventually reversing direction. Apart from the greenish leading edge, the mine is brownish and has a dirty, finely mottled appearance due to the scattered black frass grains and unevenly consumed mesophyll. The completed mines on Calamagrostis (illustrated in Eiseman (2025, p. 770)) occupied the full with of the blade for 6–9 cm, and those on Dactylis (illustrated in Eiseman (2025, p. 778)) occupied the terminal 106–123 mm of the leaf.</p><p>Puparium. Dark reddish-brown to black, formed outside the mine; according to Spencer (1969 a, 1981) and Spencer &amp; Steyskal (1986) it is frequently loosely glued to the leaf and is sometimes formed within the mine.</p><p>Phenology and voltinism. Our specimens were collected as larvae in early to mid-June and emerged as adults 14–18 days later. In Canada, adults have been collected from 2 May to 11 September and every month in between; they have been caught as early as 31 March in California and as late as 28 September in Pennsylvania (Spencer 1969 a, 1981; Lonsdale 2021).</p><p>Distribution.

The Canadian records of Spencer (1969a, p. 62) are listed under “Unidentified Leaf-mines of Agromyza species,” with the note, “This exactly resembles the mine of Agromyza alnibetulae Hendel and may well represent this species but no adults have been encountered among the hundreds of specimens examined.”</p><p>Comments. Agromyza alnibetulae was originally described from Austrian material reared from Betula pendula Roth and Alnus incana (L.) Moench, and Hering (1957) stated that this species also occurs rarely on Carpinus L. ( Betulaceae). Spencer (1969b) determined that all Alnus -associated flies represented a distinct species, which he described as Agromyza alnivora Spencer. Spencer (1990) never commented on the identity of the Carpinus feeder. We have seen linear mines of an unknown agromyzid—possibly A. alnivora —on Alnus across northern North America, but no adults have yet been reared from these. Agromyzid mines have not been found on Carpinus in North America.</p><p>An existing illustration of the male phallus of Agromyza alnibetulae was provided in Spencer (1969b, 1972), wherein a single aspect of the phallus was given. This figure was reproduced in subsequent publications until recently, but it is not entirely representative of the typical morphology of the species (B. Warrington, pers. comm.). As such, the genitalia of the newly collected male, representing one of the first two known non-Palearctic specimens, are illustrated here (Figs. 218–224).</p></div>	https://treatment.plazi.org/id/038B879BFFDB747A12C0DB4A4A47B2DB	Public Domain	No known copyright restrictions apply.

The mines on C. pallida and C. reticulata are tentatively assigned to this species based on their being formed on the lower leaf surface, unlike any other known Celtis -feeding Agromyza .</p><p>Leaf mine. On Ulmus, the mine is formed on the upper surface, usually beginning near the leaf margin; initially green and linear, later widening into a brown, elongate blotch. Frass is indistinct in the narrow, green portion, but later present in blackish particles that often form two rows, becoming more randomly scattered toward the end. Concentric feeding lines are evident in the blotch (Eiseman &amp; Lonsdale 2018: Fig. 65). Mines on Celtis may be formed on either leaf surface, may begin well away from the leaf margin, and tend to remain essentially linear throughout their length, though sometimes contorted so that this is not obvious (Eiseman et al. 2021: Fig. 59). Our new Ohio adults were reared from a collection of three C. occidentalis leaves with eight larvae forming upper-surface mines.

This is the first record of any agromyzid being reared from Arundinaria gigantea . In the male from this host, the apex of the distiphallus is more abruptly widened at the apex, not gradually narrowing from a more gradual subapical swelling to the narrower apical pore. The CSE8780 male and female are otherwise in agreement with the description of Agromyza arundinariae . Mines possibly of this species have been found on A. gigantea in Louisiana (iNat 72204531) and Florida (iNat 119528840). Similar mines have also been found on Arundinaria appalachiana Triplett, Weakley &amp; L.G.Clark in North Carolina (iNat 86452076) and Alabama (iNat 172275597). We believe these are all Agromyza mines, although mines of the A. tecta feeders Cerodontha arundinariella Eiseman, Lonsdale &amp; Feldman and C. saintandrewsensis Eiseman, Lonsdale &amp; Feldman are similar and are best distinguished by examining puparia, which are always formed within the mine in the Cerodontha species. Now that A. arundinariae has also been reared from puparia that were formed internally, it is worth noting that the puparia of this species, in addition to being substantially darker than those of the Cerodontha species, have minute, very closely spaced posterior spiracular processes, whereas on the Cerodontha puparia the posterior spiracular processes are prominent and widely spaced, with at least C. saintandrewsensis having Y-shaped horns projecting from them.

Each larva mines distally, forming a gradually widening track that eventually reverses direction, and the mines become more or less confluent.

As their morphology otherwise agrees with typical specimens, the presence of a single spine is here considered to be regional intraspecific variation.</p></div>	https://treatment.plazi.org/id/038B879BFFD8747F12C0DABE4A82B6CA	Public Domain	No known copyright restrictions apply.

This is the unidentified species on Hackelia that Eiseman &amp; Lonsdale (2018, p. 13) reported has the rare ability among agromyzids to exit its mines and form new ones elsewhere. Spencer (1969 a, 1981, 1990) noted that the genitalia of Agromyza canadensis are very similar to those of the European Boraginaceae feeder A. pseudorufipes Nowakowski, which differs externally in having much darker body coloration. Sehgal (1971) reported A. canadensis from YT based on a single male reared from Mertensia paniculata (Aiton) G.Don by G.C.D. Griffiths; he also recorded this species from AB based on numerous leaf mines on the same host. Sehgal noted that Griffiths’ specimen was dark, casting doubt on the separation of A. canadensis and A. pseudorufipes based on color, and he suspected that the two are synonymous since the genitalia “appear indistinguishable”. As the two species are still considered distinct, it is perhaps more appropriate to treat Griffiths’ specimen as A. pseudorufipes . Sehgal’s records were not mentioned by Spencer (1981, 1990), but seem to be the only basis for Mertensia being listed as a host for A. canadensis by Spencer (1990) and Benavent-Corai et al. (2005).</p></div>	https://treatment.plazi.org/id/038B879BFFDF747E12C0DC374B88B65B	Public Domain	No known copyright restrictions apply. See Agosti, D., Egloff, W., 2009.

A small hole in the leaf sometimes forms adjacent to the oviposition site (and around associated host-feeding punctures made with the adult female’s ovipositor) due to the egg being inserted in a young, tender leaf that is still expanding.

Ocellar triangle small, subtriangular and rounded, connected to dark posterolateral corner of frons by dark and more heavily sclerotized stripe along margin of vertex. Frontal vitta soft, minutely textured; orbital plate softer anteriorly. Scutum subshining. Both specimens in poor condition; female with damage to most setae and both first flagellomeres missing.</p><p>Chaetotaxy: Two ori, two ors, slightly decreasing in length anteriorly.

Two strong dorsocentrals, with anterior seta about ⅘ length of posterior; third possible dorsocentral seta close to second seta not much longer than setulae.Acrostichal seta present, small and thin. Eight rows acrostichal setulae. Mid tibia without medial setae.</p><p>Coloration:Setae dark brown.Head mostly orange with brownish tint; back of head,ocellar triangle, posterolateral corner of frons (including base of vertical setae) and clypeus dark brown; orbital plate dark posteriorly, brown around level of ors; lateral margin along eye with dark line that disappears towards ori; posterior half of frontal vitta slightly more brownish in male; venter of gena with brown line; parafacial and face yellowish with antennal grooves brown. Thorax dark brown with pale mottling narrowly along lateral margin of notum. Calypter margin and hairs light brown with slight yellow shine. Halter white. Wing veins light brown. Legs mostly dark brown; apex of fore femur yellow for distance almost equal to width; mid femur narrowly yellow at apex laterally; fore tibia slightly yellowish in male, more obviously yellow in female, with base broadly yellow; mid tibia yellowish at base; tarsi yellowish-brown. Abdomen dark brown.</p><p>Genitalia: (Figs. 225–231) Surstylus almost entirely fused to epandrium, but faint suture evident laterally. Cercus large, broadly rounded apically, and inner surface densely covered with minute tubercle-like setae on distal half. Postgonite with several small setae on inner surface, with narrower distoventral lobe, and long basal “tail”. Hypandrium subtriangular with broad inner lobe that is slightly raised anteriorly with a single minute seta; lobe centrally with one additional seta and several minute setae. Phallophorus subcylindrical and asymmetrical, with most of right side absent and left dorsolateral margin fused to narrow, ribbon-like basiphallus wrapping around dorsum of shaft; with dark basal ring. Hypophallus membranous, with small serrated margin and clear anteromedial process; ejaculatory duct wide, especially swollen on distal half of phallus, apex flattened and ventrally curved; mesophallus flat, narrow, apex wider and bifid. Distiphallus narrow in ventral view, ventral margin long and haired along suture; in lateral view, relatively high and with strong basal “hook”. Ejaculatory apodeme well-developed with short, wide stem and clear sperm pump.</p><p>Comments. The leaf mines of Agromyza celtitexana are generally similar in appearance to some formed by A. aristata (Eiseman &amp; Lonsdale 2018: Fig. 65) and A. fission Eiseman &amp; Lonsdale (Eiseman &amp; Lonsdale 2018: Fig. 68) on Celtis spp., but the initial narrow, green, interparenchymal or lower-surface portion is not present in the mines of these species in our experience. A mine with this feature, confirmed as a lower-surface portion by a photo of the lower leaf surface, has been found on C. laevigata in Louisiana (iNat 251717490). Larvae of A. aristata are present only in spring, and their mines on Celtis are frequently entirely on the lower leaf surface, whereas all known examples of A. celtitexana are on the upper surface, and the larvae were active in summer. Mines of A. fission tend to be more contorted than those of A. celtitexana, are shorter, and widen to elongate blotches. We have yet to see a confirmed mine of A. varifrons Coquillett, but according to Spencer &amp; Steyskal (1986) mines of that species also widen to blotches and (unlike A. celtitexana) most often follow the leaf margin. In Ontario and throughout the eastern USA, we have seen Celtis leaf mines evidently representing yet another Agromyza species (discussed below as Agromyza sp. 2); larvae are present only in spring, and the mine invariably begins at the midrib with a long, winding, very narrow linear portion, then widening and usually following the leaf margin. See the key below under A. deserta (Patton) for an attempt to distinguish among the immature stages and feeding damage of all known Nearctic Celtis -feeding Agromyza spp., including another, undetermined species from Texas ( Agromyza sp. 1).</p><p>Within a few days after the male and female adults of Agromyza celtitexana emerged, a female Opius Wesmael ( Hymenoptera: Braconidae) emerged from another puparium from the same collection of mines.</p><p>The new species is similar to Agromyza fission, a related species that is larger (wing 2.3–2.5 mm), darker and with three strong dorsocentrals. The genitalia of A. fission also differ in having the cercus apically split (not broadly rounded), the mesophallus is less developed, and the distiphallus is smaller, slightly wider apically, more shallow (seen laterally) and the base does not have a strong, rounded “hook” (Lonsdale 2021: Figs. 183–187). In the same Celtis -mining group is A. varifrons, which is also slightly larger, and the antenna, face and frons are mostly yellow; with regards to the genitalia, no remnant of the surstylus is apparent, the basiphallus is longer and the mesophallus shorter, the ejaculatory duct at the level of the mesophallus is swollen, and the distiphallus is smaller, paler, upturned and narrowed apically (Lonsdale 2021: Figs. 236–242). The dark basal ring of the phallophorus of the new species is also unique.</p></div>	https://treatment.plazi.org/id/038B879BFFDE747D12C0DFC64957B3D7	Public Domain	No known copyright restrictions apply.

USA: [AR, CT (Patton 1897), IA, IL, KS, KY, MD (Spencer 1988), MN, MO, NC, NY (Scheffer &amp; Lonsdale 2018), OH], *OK, [PA, SC, TX, VA], WV (von Tschirnhaus 2017). Although Connecticut is the type locality, this species was described from the gall alone, and the only known adult specimens are the West Virginia one described by von Tschirnhaus (2017) and the Oklahoma ones listed here.</p><p>Comments. The new male specimen and the first known female examined here present some variation not previously noted. The female wing length is 3.7 mm and the basal ⅓ of each tibia is pale (not just the base). Regarding differences observed in both sexes, there are five fronto-orbitals that are not readily differentiated into ori and ors; there appear to be five dorsocentrals, with the anterior seta often barely distinguishable from the surrounding setulae; the first flagellomere has an anterodorsal angle that is rounded and barely evident to slightly more pronounced; the first flagellomere is either entirely brown (female), or brown on the outer-basal half (male); the side of the frons at and behind the posterior fronto-orbital is more thinly darkened; the paler parts of the body are not yellowish-white, but pale orange with a yellowish tint; the matt gray pruinosity covers all darker parts of the body except for the antenna, is sparser on the legs past the coxae with the fore femur still having the pruinosity relatively pronounced, and it is nearly absent on the tibiae and tarsi. A correction to Lonsdale (2021) is also provided here, as a couplet in the species key infers that the calypter of this species is white, when it actually brown on the hairs and along the margin.</p><p>With the named Celtis -feeding Agromyza species now numbering seven, a new key is provided here to better differentiate them:</p><p>1.

Gould, [ D. scribnerianum (Nash) J.R.Thomas].</p><p>Leaf mine. (Fig. 98; Eiseman &amp; Lonsdale 2018: Fig. 72) Eggs are inserted near the leaf margin (rarely closer to the midrib), associated with a cluster of feeding punctures. The usually gregarious larvae initially mine along the margin toward the apex, then turn around and form a large, dirty whitish upper-surface blotch with generally distributed, liquidy, greenish to brown frass. Concentric feeding lines are present in some mines.</p><p>Puparium. (Fig. 6) Yellowish-brown to reddish-brown; formed outside the mine. Spiracles separate or adjacent (appearing fused at base); sometimes with three pores on basally connected triangular extensions that diverge at acute angles laterally, sometimes duplicated as 6 or more (perhaps 12) pores that radiate in a C-shaped fan.</p><p>Phenology and voltinism. Larvae collected in early May (North Carolina; tentatively identified material from Arkansas) and mid-June (Massachusetts) overwintered as pupae, emerging as adults the following spring. Larvae collected in early June (North Carolina), late June (tentatively identified material from Wisconsin), and early July (Massachusetts) emerged as adults 18–20 days later. A collection of larvae from Massachusetts in mid-August produced some adults 18–23 days later and some the following spring.</p><p>Distribution. USA: CT, DC, MA, MD, NC, NJ, [WI].</p><p>Adult description. (Fig. 5) Wing length 2.5–2.6 mm (♂), 2.4–2.8 mm (♀). Length of ultimate section of vein M 4 divided by penultimate section: 0.5–0.7. Eye height divided by gena height: 6.1–8.2. First flagellomere sometimes rounded, or with dorsal and ventral margins relatively straight and converging to narrow apex; apical tuft of hairs on first flagellomere not much wider than base of arista. Ocellar triangle sometimes evident beyond darker ocellar tubercle, narrow, nearly reaching level of anterior ors. Notum subshining.</p><p>Chaetotaxy: Two ors, two to three ori; decreasing in length anteriorly; third ori sometimes only present on one side and reduced. Postvertical and ocellar setae subequal to anterior ors, but thinner. Two strong dorsocentral setae with smaller, thinner third seta (less than half length of second) very close in front of second seta. Acrostichal setulae in 8 rows. Acrostichal seta as strong as second dorsocentral. Mid tibia with two posteromedial setae.</p><p>Coloration: Setae dark brown to black. Body mostly dark brown to black; base of fore tibia and all tarsi brownish-white; apex of fore femur sometimes also pale, being whitish to light yellow; apex of fore tibia sometimes yellowish; pedicel sometimes entirely or distally orange, and inner basal margin of first flagellomere less commonly orange also. Wing veins brownish-white. Calypter margin white, hairs brown to dark brown.</p><p>Genitalia: (Figs. 232–236) Epandrium with desclerotization on anterior margin adjacent to surstylus base. Surstylus not visible laterally, fused to epandrium, anterior region more prominent; inner surface with 18–26 tubercle-like setae. Cercus well-developed. Postgonite well-developed, typical of genus. Hypandrium with bowed sides and narrow apodeme that may have end pointed or more rectangular; base with arms short and with short narrow ventral extension for exterior articulation; inner lobe broad, squarish, with distal margin better sclerotized and with several minute grooves ending in sockets, one or two of which includes a short seta. Phallophorus asymmetrical, with venter and right side mostly atrophied past base. Basiphallus sclerites diverging from base, with small ventromedial membranous lobe, and end abruptly folded inwards with pointed apices nearly touching medially; left sclerite broader and better sclerotized basally with stout basal arm wrapping around shaft; right sclerite broad and ill-defined at base, appearing to be weakly fused to atrophied region of phallophorus. Distiphallus typical of grass-feeding Agromyza, capsule-shaped with base rounded, dorsum supported by narrow transverse band, and duct entering segment through ventral cracks; segment nearly straight, except base and apex slightly angled dorsally, and with shallow curve before midpoint; inner surface minutely spinulose before pale dome-like apex that is not much wider than preceding region but clearly delimited by sharp constriction; wider than high past midpoint, with lateral surface slightly curved, and open ventral suture that is divided by narrow folded sclerite apically. Ejaculatory apodeme with broad asymmetric base; stem absent; blade well-developed with margin clear and with medial offset sclerotized band along most of length; sperm pump clear.</p><p>Variation: One male reared from Dichanthelium scoparium, and the dissected males from Colesville (Maryland) and Putnam (Connecticut), differ in having calypter hairs yellow, distiphallus narrower on the distal half, and pale terminal section slightly shorter ventrally and with minute tubercles across inner surface (Figs. 237–239); the second undissected reared male appears “typical” in having dark brown calypter hairs. Other undissected males from the District of Columbia, Maryland and New Jersey (USNM) with whitish calypter hairs agreeing with the above are treated as conspecific.</p><p>Comments. In Lonsdale (2021), Agromyza parca Spencer was described as a variable species with recognition that it likely harbored an additional cryptic taxon. Re-examination of material reported in Eiseman &amp; Lonsdale (2018) and Lonsdale (2021), along with newly collected material listed here, now allows for delineation of a narrowed version of A. parca that is restricted to Glyceria, and a new miner occurring on Dichanthelium can be described. Additional specimens reared from “ Poaceae ” are here treated as A. parca, with the host of these also likely being Glyceria .</p><p>Only one female tentatively identified as Agromyza parca does not easily fit the descriptions provided. As with some A. dichanthelii, the calypter hairs are dark brown, and the tuft of hairs on the first flagellomere is barely larger than the width of the arista. Despite this, the female was reared from Glyceria and the posterior puparial spiracles are typical of A. parca .</p><p>Agromyza dichanthelii is also quite similar in appearance to A. pudica (Lonsdale 2021: Figs. 216–220), another miner of Dichanthelium, and while external morphological characters do exist for differentiation, such as the morphology and color of the antenna and calypter, these are slight and likely to be confused, especially in poorly preserved specimens. If reared, many specimens of A. dichanthelii can be diagnosed by having the posterior spiracles of the puparium separate or with more than three pores, although some resemble the spiracles of A. pudica . Only the male genitalia consistently differ in the shape of the distiphallus (medially constricted in A. pudica) and the apex of the basiphallus (apically V-shaped in A. pudica). Unless accompanied by confidently associated males, females may not be identifiable.</p><p>With clarification of these species concepts, the Agromyza species key in Lonsdale (2021) can be updated as follows:</p><p>23. Apical tuft of hairs absent from first flagellomere. Calypter hairs dark brown. Basiphallus produced laterally into 1 pair of large, triangular, basally sclerotized wings.

While the above specimens have six and eight spines, it seems reasonable at present to expand the definition of this species to having five to eight spines until additional material can be accumulated to more thoroughly question species limits.</p></div>	https://treatment.plazi.org/id/038B879BFFC0746012C0DFBC4B31B375	Public Domain	No known copyright restrictions apply.

(Eiseman &amp; Lonsdale 2018: Fig. 68) Whitish; initially linear, sometimes highly contorted, widening to an elongate blotch; frass dark greenish to black, forming two fine rows of beaded strips in the linear portion, and randomly deposited in scattered grains and small, irregular lumps in the blotch. In most cases a small hole in the leaf forms around the oviposition site due to the egg being inserted in a young, tender leaf that is still expanding (as noted above for A. celtitexana; we have never observed this in mines of A. aristata, which can otherwise be very similar to those of A. fission). All of the new specimens were reared from mines that began at or near the leaf apex, where the larva began by forming a more or less intestine-like contorted track (as in BG 2106804).</p><p>Puparium. Yellowish-brown to orange-brown, with three bulbs on each posterior spiracle; formed outside the mine.</p><p>Phenology and voltinism. Larvae have been collected in early March (Texas), early April (North Carolina, Oklahoma) and mid-July (Iowa, Wisconsin), in each case with some adults emerging in 2–4 weeks, and with some from the April and July collections not emerging until the following spring (Eiseman &amp; Lonsdale 2018).</p><p>Distribution. USA: IA, MD, *NC, OK, *TX, WI (Eiseman &amp; Lonsdale 2018).</p><p>Comments. The newly examined specimens differ in having paler antennae with a very faint infuscation restricted to a small spot posterior to the arista base on the outer surface, similar to some A. varifrons . The male is also smaller than those previously examined, having a wing length of 2.0 mm. The female in collection CSE7967 has a first flagellomere with a broad black infuscation along the dorsal and anterior margins that extends more towards the outer surface.</p></div>	https://treatment.plazi.org/id/038B879BFFC0746712C0DAEC49D7B7EB	Public Domain	No known copyright restrictions apply.

The mines of this species do not seem to be distinguishable from those of the Holarctic Agromyza albitarsis Meigen (currently confirmed in North America only from British Columbia and Vermont, with some older records representing misidentifications of A. isolata), and thus it is entirely possible that the records of Salix bebbiana (Spencer 1969a) and Minnesota (Spencer &amp; Steyskal 1986), which are based only on empty leaf mines, actually refer to that species. Eiseman &amp; Lonsdale (2018) observed differences in puparium size and color at a site where the two species were found together, but further rearing has shown that these differences are not consistent.</p></div>	https://treatment.plazi.org/id/038B879BFFC7746712C0DF564DFAB247	Public Domain	No known copyright restrictions apply.

This rearing confirms the host suspected by Lonsdale (2021), who collected four females from C. occidentalis in Ontario.</p><p>Leaf mine. (Figs. 101, 102) A pale greenish primary blotch on the upper surface, bounded by the midrib and/or other major veins; the final shape may be elongate or more compact. Secondary feeding lines are sometimes visible toward the end. The frass is initially indistinct, deposited centrally and becoming progressively darker green to blackish, in irregular lumps and threadlike fragments. The larva exits through a slit in the upper epidermis.</p><p>Puparium. (Fig. 8) Yellowish-brown to orange-brown (pale yellow when empty); formed outside the mine. Narrow, with margin outside posterior surface curving immediately onto longitudinal surfaces. Posterior spiracles on short stalks bearing pores on wider, darker platform, and with bases strongly widened and touching on inner margin; pores curved, two long pores directed dorsally and ventrally, and one shorter pore on outer medial surface; apices of spiracles more closely spaced than they are to ventral tubercles, which are about as long as and more distantly spaced than spiracles, with wide, flat intervening space. Puparium of A. varifrons very similar, but color darker, more reddish-brown (when empty), and more broadly rounded, with posterior face more gradually curving onto longitudinal surfaces.</p><p>Phenology and voltinism. The only known reared specimens were active as larvae in mid- to late June and overwintered as pupae, emerging as adults the following spring (Fig. 7). The six other known specimens (all females) were collected as adults from late April (Florida) to late May (Ontario and Washington, D.C.; Lonsdale 2021), consistent with a strictly univoltine species. Mines we believe to represent this species have been found as early as late March in Florida; they have been found in April in Texas, Mississippi, and North Carolina, and by the end of May as far north as Minnesota and Pennsylvania.

It is a more regular blotch toward the center of the leaf blade and possibly represents and undescribed species.” Since all other known Celtis -mining Agromyza species form mines that are largely or entirely linear (summarized above under A. celtitexana), we believe this was a mine of A. pallidiseta, along with the similar mines mentioned by Eiseman &amp; Lonsdale (2018, p. 10), which are among those listed above under Photographed mines. The vouchered male was not dissected as it represents the only known representative of that sex in this species.</p></div>	https://treatment.plazi.org/id/038B879BFFC6746412C0DABF4C39B67F	Public Domain	No known copyright restrictions apply.

The specific epithet refers to the close relationship of this species to Agromyza soka Eiseman &amp; Lonsdale (Gr. para —beside, near).</p><p>Hosts. Fabaceae: Wisteria floribunda (Willd.) DC., [ W. sinensis (Sims) DC.]. Although the host plants of the reared specimens morphologically match W. floribunda, they may in fact be hybrids of W. floribunda and W. sinensis, as is the case with most Wisteria invading natural areas in North Carolina (B. England, in litt.).</p><p>Leaf mine. (Figs. 106–108) The egg is inserted in the leaflet midrib at or near the apex. The larva initially forms a winding linear mine, roughly following the midrib toward the base for 3 cm or so; it then turns and forms an elongate greenish blotch back toward the apex. The frass is generally diffuse.</p><p>Puparium. (Fig. 10) Reddish-brown; formed outside the mine.</p><p>Phenology and voltinism. This species is univoltine, with larvae active from late March to mid-April, overwintering as pupae and emerging as adults the following spring.</p><p>Distribution. USA: [AL], NC.</p><p>Adult description. (Fig. 9) Wing length approximately 2.7 mm (♂ ♀). Length of ultimate section of vein M 4 divided by penultimate section: 0.5–0.7. Eye height divided by gena height: 7.1–12.3. First flagellomere rounded in male; slightly elongate and more ovate in female, with apex slightly tapering; distal margin in both sexes with longer hairs that form a circular tuft medially. Outer margin of orbital plate with narrow tomentose line that is silvery in some light. Ocellar triangle poorly defined, appearing to end just anterior to posterior ors. Scutum subshining.</p><p>Chaetotaxy: Two ori (sometimes three on one side), two ors. Postvertical and ocellar setae longer than fronto-orbitals. Few setulae present on anterior sunken margin of frons. Five dorsocentral setae, gradually becoming shorter to anterior presutural seta, which may be indistinguishable from surrounding setulae. Prescutellar acrostichal seta slightly shorter than posterior dorsocentral. Acrostichal setulae in 8 rows. Anatergite and katatergite with several additional shorter setae.</p><p>Coloration: Setae dark brown with slightly paler reflection. Color mostly dark brown, with head and legs past coxae slightly paler. Female scape and pedicel yellow with orange tint, and outer basal margin of first flagellomere slightly orange. Gena, and sometimes frontal vitta with beige tint; face orange immediately below antennal insertion. Clypeus, palpus, ocellar spot, center and sides of face, parafacial, venter of gena and back of head dark brown. Thorax slightly paler in patches laterally along scutum. Halter white. Wing veins yellow. Calypter with yellow margin and brown hairs. Fore leg with apex of femur and base of tibia very narrowly yellow in male (difficult to discern), but wider in female; female mid and hind legs with apex of femur and base of tibia narrowly yellow; female tibiae paler, slightly brownish white in color, being darkest on hind leg and brightest on fore leg; female tarsi brownish white, being darker on hind leg and brightest on fore leg.</p><p>Genitalia: (Figs. 243–248) Surstylus fully fused to epandrium, inner surface covered with many small, rounded tubercles. Cercus narrow, well-developed. Hypandrium with apodeme well-developed and triangular, and inner lobe large and rounded with many small lateral sockets and one small medial seta. Postgonite with long, curved tail-like base, which is fused to inner surface of lobate, plate-like body with several small setae on inner-medial surface. Phallophorus length twice width, cylindrical with right distal margin recessed. Basiphallus with narrow ventrobasal plate; otherwise composed of large bifid dorsal to left lateral plate, the distal branches of which are angled ventrally to fuse and form plate that lies below small, narrow hypophallus; with narrower dorsoapical extension that wraps around base of distiphallus. Mesophallus very large and subspherical, partially fused ventrally to distiphallus. Distiphallus very dark, with thick basal stem and broad, shallow apical section from which one pair of pale, thin structures emerge. Ejaculatory apodeme with broad base and thick stem that gradually widens to meet blade.</p><p>Comments. Both Agromyza parasoka and A. soka Eiseman &amp; Lonsdale are univoltine, mining fresh leaves of Wisteria floribunda in spring and not emerging as adults until the following spring. In both species, the egg is normally inserted in the apical portion of the leaflet midrib, but whereas in A. soka the initial linear portion (if present at all) is only about 1 cm long and proceeds distally, in A. parasoka it is several cm long and follows the midrib toward the base of the leaflet. Mines of the latter type have never been found on Robinia, a host commonly used by A. soka . The mine of the Japanese A. wistariae Sasakawa also begins with a prolonged linear portion, but this is initiated at the leaflet base and runs along the margin toward the apex (Sasakawa 1961). Wisteria floribunda is native to Japan; assuming A. parasoka is native to North America, it presumably also feeds on W. frutescens (L.) Poir. or some other native legume. However, the only leaf-mining insects we have found on W. frutescens are Pachyschelus nicolayi Obenberger ( Coleoptera: Buprestidae) and Macrosaccus robiniella (Clemens) ( Lepidoptera: Gracillariidae), neither of which has been found on W. floribunda .</p><p>Agromyza parasoka, as indicated by the name, is closely related to A. soka, which also occurs on Wisteria . The few apparent external characters differentiating the new species are the following, but these may prove to be negligible following the collection of additional material: three mid tibial setae (not one or two), an entirely dark first flagellomere in the male and one known female and a basally orange segment in the remaining females (not broadly orange basally in both sexes). The male genitalia of both are distinct, and should ideally be examined for identification. In A. parasoka, the inner-distal surface of the fused surstylus/epandrium is covered with small tubercles (not with a few long spines); the hypandrium is longer and more triangular apically; the fused sections of the basiphallus and hypophallus differ, as does the shape and dorsal orientation of the distiphallus; the mesophallus is much larger and more spherical (not smaller and stem-like); and the ejaculatory apodeme is thicker.</p><p>If a male is unavailable, the posterior surface of the puparium can also be used for differentiation. In both species, the spiracles are borne on a black swelling with three white transverse J-shaped lines crossing it; in Agromyza soka, the swelling is relatively small and ovate while it is larger and nearly spherical in A. parasoka . The terminal segment bearing the spiracles is also diagnostic. In A. soka, the segment is very small with the base of the segment abutting the base of the subconical projections bearing the spiracles, and the projections are touching at the base. In A. parasoka, the segment is much larger, the projections are well-separated and resting below a U-shaped groove, and the ventral tubercles are widely spaced and positioned below a pair of small pits.</p><p>Agromyza wistariae is also similar, agreeing in most respects with the description of the female of the new species, but males are unfortunately unknown. Based on the description in Sasakawa (1961) (specimens are not available), this species differs in having darker brown calypter hairs, the scape and pedicel are paler distally, the face and parafacial are pruinose and grayish-white, and the mid tibia has zero or two medial setae. The host also differs, with rearing records from Wisteria brachybotrys Sieb. &amp; Zucc and Wisteriopsis japonica (Siebold &amp; Zucc.) J.Compton &amp; Schrire, and the larval mine differs as noted above. The posterior spiracles of the larva also differ in being much smaller and unmodified, without a strong dark apical swelling and without distinct elongate white Jshaped stripes (Sasakawa 1961: Fig. 15n).</p></div>	https://treatment.plazi.org/id/038B879BFFC4746B12C0DFE24A01B14B	Public Domain	No known copyright restrictions apply.

Trin., G. *melicaria (Michx.) F.T.Hubb., G. striata (Lam.) Hitchc. (Eiseman &amp; Lonsdale 2018) . The undetermined Poaceae host of the Iowa specimens listed by Eiseman et al. (2021) was likely also a Glyceria sp., based on the habitat (stream margin) and what is visible of the leaves in our photographs of the larval mines (Fig. 111). Our previous records of A. parca from Dichanthelium spp. (Eiseman &amp; Lonsdale 2018; Eiseman et al. 2021) refer to A. dichanthelii sp. nov. (see above).</p><p>Leaf mine. (Figs. 110, 111) Several eggs are laid in close proximity, without associated host-feeding punctures in the examples we have seen. The larvae initially form narrow mines toward the leaf apex, sooner or later reversing direction and merging to form a whitish- to yellowish-green blotch that may occupy the full width of the leaf. Fine, closely spaced, granular frass is deposited throughout the mine. In some cases, mines are on the abaxial leaf surface, but the leaf is twisted so that the mined portion faces upward.</p><p>Puparium. (Fig. 12) Reddish-brown to blackish-brown; formed outside the mine. Posterior spiracles distantly separated, with 3 narrow, widely separated pores. Also see Guglya (2025, including Figs. 17–18).</p><p>Phenology and voltinism. Larvae collected in Iowa, Massachusetts, and Connecticut in mid- to late June, mid-July, and late July emerged as adults (Figs. 11, 240–242) 13–23 days later (Eiseman &amp; Lonsdale 2018; Eiseman et al. 2021).</p><p>Distribution. USA:CT, IA, MA, MD, NC,TN (Eiseman &amp;Lonsdale2018; Eiseman et al. 2021); Ukraine (Guglya 2025). Of the specimens reported for this species in Lonsdale (2021), only five from Maryland and Massachusetts are retained in this species, as listed above. Some of the specimens from Maryland are now paratypes of A. dichanthelii, as are all specimens reared from Dichanthelium, as well as the males from the District of Columbia, Connecticut, and New Jersey; one female from Connecticut is also tentatively placed in that species. The remaining females could not be confidently placed, and are identified as “ Agromyza sp. ”; these are from Connecticut, Maryland, New Hampshire, and New York. Grigoryan &amp; Hovhannisyan (2025) reported A. parca from Azerbaijan and stated that it is “quite widespread in the Palearctic region, China, Japan, [and] the Nearctic region,” citing Nartshuk (2019). The latter publication in fact makes no mention of A. parca, and we are unable to confirm the identification of the Azerbaijan material based on the images provided by Grigoryan &amp; Hovhannisyan (2025), especially given the novel host genera reported. Guglya (2025) noted that N. Grigoryan was unable to determine the true source of the distribution records that were erroneously attributed to Nartshuk (2019), and we presume they referred to another species.</p><p>Comments. Eiseman &amp; Lonsdale (2018) discussed a Massachusetts female as “ Agromyza sp. 5,” but we are now satisified that it represents A. parca .</p><p>Although Agromyza parca so far has been found exclusively on Glyceria spp. in North America, Guglya (2025) has reared specimens that appear entirely consistent with this species from Setaria viridis (L.) P.Beauv. in Ukraine. No Agromyza species has been reared from Setaria in North America, although two species that occur here, A. albipennis and A. nigrella (Rondani), have been reported from this host genus elsewhere (Spencer 1972; Ellis 2024). Several Old World Setaria species are common in New England, and CSE has occassionally found Agromyza mines on S. pumila (Poir.) Roem. &amp; Schult. in Massachusetts and Vermont, but no adult emerged from the single puparium obtained.</p></div>	https://treatment.plazi.org/id/038B879BFFCB746A12C0D8B64891B137	Public Domain	No known copyright restrictions apply.

Larvae confirmed as A. pudica have been found in Oklahoma and North Carolina in early to late May, mid-July, and early August; farther north, they have been found in Massachusetts in early July and in Ohio in early August (Eiseman &amp; Lonsdale 2018, 2019).</p><p>Distribution.

The tentatively identified male is considered as such since the genitalia match those of Agromyza ambrosivora (distiphallus apex strongly curved and split), but it otherwise agrees with the original species description. This includes chaetotaxy, wherein it is differentiated from A. ambrosivora by “having two ors rather than one, [and] three ori rather than four” (Scheffer &amp; Lonsdale 2018). Given this discrepancy, it appears as though only host and fronto-orbital number are reliable for diagnosis. Alternatively, the two species may be conspecific with morphological variation in phallic structure possibly correlated to host plant species.</p></div>	https://treatment.plazi.org/id/038B879BFFC8746812C0DFAA4CEDB183	Public Domain	No known copyright restrictions apply.

In mines that we have been able to examine closely while still fresh, it was evident that the egg was inserted in the leaflet midrib and the mine began as a narrow (~ 0.2 mm) line, arcing away from and then back toward the midrib, which it followed for up to 13 mm before reaching the leaflet apex, at which point it widened and contorted. In other photographed mines this initial linear portion is not evident, but it does appear that the egg is usually inserted in the midrib in the apical portion of the leaflet. In some mines on Wisteria, the mine is not as tightly contorted and is thus more clearly linear, at least toward the end.

The specific epithet is derived from the Latin “ tortilis,” for “twisting” and “winding,” most notably referring to the leaf rolls formed by the larvae, but also applicable to the unusual and unique twisting basiphallus of the male.</p><p>Host. Cannabaceae: Celtis laevigata Willd.</p><p>Leaf mine. (Figs. 103, 104) Each of the specimens listed above was reared from a tender young leaf that was tightly rolled downward into an oblique, cigar-like roll that occupied the whole leaf (or nearly so) and entirely concealed the mine. When we unrolled some of these leaves, each was found to have a single mine, which appeared brown and full-depth (we were unable to determine on which leaf surface the mines originated, although one unaffected leaf collected along with the rolled leaves was found to have an early-instar larva forming a lower-surface mine; this may, however, have been a larva of A. aristata, one specimen of which was also reared from a collection of rolled leaves). One similarly rolled leaf had no mine inside, leading us to suspect that the rolling was somehow caused by oviposition rather than by larval feeding. The 11 April 2022 collection consisted of two rolled leaves, which yielded six puparia.</p><p>Puparium. Reddish-brown; posterior spiracles large, C-shaped, with ~16 marginal pores on C-shaped plate; formed outside the mine.</p><p>Phenology and voltinism. Larvae are active from late March to mid-April, with pupae overwintering and adults emerging the following spring.</p><p>Distribution. USA: NC.</p><p>Adult description. (Fig. 16) Wing length 2.2 mm (♂), 2.6 mm (♀). Length of ultimate section of vein M 4 divided by penultimate section 0.7. Eye height divided by gena height: 4.1–4.3. First flagellomere well-developed, slightly elongate with longer distal marginal hairs. Epistoma present, much broader than high, nearly as high as first flagellomere, deeper at middle. Body subshining, but thorax with dense gray-blue pruinosity. Orbital plate and parafacial visible laterally, modestly projecting, forming narrow ring around eye. Clypeus broad and straight anteriorly.</p><p>Chaetotaxy: Two ori, two ors; relatively short and decreasing in length anteriorly, shorter than ocellars and larger postverticals. Four dorsocentrals, decreasing in length anteriorly, with anterior two thinner and fourth slightly longer than setulae; acrostichal setulae in six irregular rows.</p><p>Coloration: Setae dark brown to black. Mostly dark brown; frons and anterior region of head light yellow with brownish spots at base of ors; broad semicircular dark spot around tubercle; posterolateral corner of frons dark brown to base of inner vertical; clypeus brown and first flagellomere deeper yellow. Thorax pruinosity dense grayish-blue; pigment slightly paler in faint irregular pattern from postpronotum to wing base. Wing veins light yellow with irregular brownish spots on R 1; calypter with whitish margin, hairs light brown to brown. Apices of femora light yellow for distance about equal to apex width; base and ends of tibiae light yellow (more extensive on fore leg, less so on hind), tarsi light yellow with apical segments slightly darker.</p><p>Genitalia: (Figs. 249–255) Epandrium shallow, dome-like, fully fused to shallow, incurved, subtriangular surstylus that only bears short setae. Cercus length nearly equal to epandrium height, much narrower on distal ¼, and with several short, stout, darker setae on anterodistal surface. Hypandrium subtriangular with sides slightly bowed and apex with long, dark apodeme; inner lobe thick and curved with inner-basal region darker, with several short setae scattered along margin with weaker outer region. Postgonite with large apical lobe that is strongly incurved with minute setae along ventral surface; base of lobe bumpy, irregular, and covering base of long, dark, smooth band that fuses to phallapodeme. Ejaculatory duct wide, with dorsal and ventral sclerotized plates before ending at distiphallus, with the ventral plate very likely representing the mesophallus. Phallapodeme elongate, bent at midpoint, more weakly sclerotized on distal half (which is possibly homologous to base of basiphallus), open along most of right lateral surface, and with weakly sclerotized “window” on left distal half; basal half very dark along venter, bridge to epiphallus, and left ventrolateral strip. Basiphallus dark, curling around phallus shaft, with narrower base originating on left lateral surface where it is fused to dorsal and left lateral margins of phallophorus; basiphallus becomes much broader dorsally, and at right lateral surface, it splits into two branches; left branch apically paler, pointed and minutely spinulose; right branch flat, ribbon-like, with desclerotized line along midline, and inner face closely adjoining distoventral surface of ejaculatory duct. Distiphallus approximately half as long as basiphallus, relatively pale, and flared apically; with raised vental suture; seen ventrally, about as long as wide, narrowest medially, and with broad ventrobasal extensions that adjoin distal margin of ventral plate of ejaculatory duct. Ejaculatory apodeme subtriangular, very dark, especially along nearly straight distal and lateral margins, and with relatively broad, stout base; sperm pump broad, clear.</p><p>Comments. Most observations of the leaf rolls on Celtis laevigata associated with this species have been found at a single locality in Scotland Co., North Carolina, but they have also been found in Wake Co. (iNat 213021473). TSF originally collected them on 13 April 2021 with the assumption that they were created by lepidopteran larvae, and when the first puparium appeared in a vial of leaf rolls (SA1962), it was transferred to a vial containing mined (but not rolled) leaves collected from the same tree on 6 April (SA1954). Three puparia were ultimately obtained from the leaves collected on 6 April, and from the four total puparia in the vial, three adults of Agromyza fission emerged (CSE6887, CSE7339). The fourth puparium, from which nothing emerged, probably belonged to A. torta . However, the only adult to emerge from the puparia that remained in the SA1962 vial was a male of A. aristata (CSE7378). We suspect that this male originated from a larva that happened to be mining a leaf that was rolled by A. torta, because every subsequent adult we have obtained from a rolled C. laevigata leaf belonged to this species. Similar leaf rolls that appear to be associated with mining have been found on C. reticulata in New Mexico (iNat 160440484).</p><p>When lepidopteran larvae create superficially similar leaf rolls, they invariably do so using silk, which causes the leaves to curl because it contracts as it dries. We found no trace of silk in any of the leaf rolls that we opened, nor was there any external frass or feeding damage as there would be in a lepidopteran leaf roll (Eiseman &amp; Charney 2010). We are therefore confident that Agromyza torta is responsible for the rolls, and although the mechanism is unknown to us, the rolling is evidently induced by the ovipositing female (see above under Leaf mine). The roll can be considered a type of gall, and it is noteworthy that the related species A. deserta also induces galls on Celtis .</p><p>In addition to the distinctive leaf roll in which the larva forms its mine, the adult of Agromyza torta is also quite diagnostic. The body is dark with relatively dense bluish-gray pruinosity covering the thorax, and the head is contrastingly pale with a narrow ring around the eye, a dark semicircular spot around the tubercle, broad dark corners in the posterolateral corner of the frons and spots at the base of the ors. The male genitalia associate this species with the other Celtis feeders, but beyond this, most of the components are highly distinct and not readily confused for those of the others. The cerci are quite narrow apically with inner-apical spine-like setae; the basiphallus is dark, bifid and twisted; the distiphallus is smooth, short and broad, with the base adjoining a broad, pale mesophallus on the ventral surface.</p></div>	https://treatment.plazi.org/id/038B879BFFCE746C12C0DDDE4900B65B	Public Domain	No known copyright restrictions apply.

The holotype was collected as an adult on this host and presumed to be associated with leaf mines noted on the same plant (Spencer 1969a), but this species had not been reared until now.</p><p>Leaf mine. (Fig. 113) Initially linear, with black frass in closely spaced grains, sometimes forming two neat rows; widening dramatically, with the frass scattered at random in grains and small lumps; becoming an elongate or irregular blotch by the end. The mine is pale brown at first, becoming more or less suffused with darker brown, with concentric feeding lines often evident.

Agromyza spiraeoidearum Hering, which in North America has only been collected in British Columbia, feeds on Spiraea spp. in Europe. Spencer (1969a) stated that the mines of A. spiraeoidearum “are broadly linear, less obviously blotch-like, and whitish gray, not brown as in valdorensis .” The only example we have seen of an Agromyza mine on Spiraea from west of Minnesota is one found on S. douglasii Hook. by E. Stansbury in Washington (Thurston Co., Lacey) on 25.viii.2018; it does not differ markedly in color from those of A. valdorensis, but it is linear throughout and we presume it represents A. spiraeoidearum .</p></div>	https://treatment.plazi.org/id/038B879BFFCC746C12C0DFC64BB0B1DF	Public Domain	No known copyright restrictions apply.

The single photographed mine, with the larva still inside (iNat 152331931), was gradually widening, entirely linear, on the upper surface, beginning at the leaf margin, near the base, and meandering toward the apex.

This female is only tentatively treated as distinct from the highly similar Agromyza varifrons, which also feeds on Celtis and does not appear to differ in puparial morphology. The leaf mine is also similar, but that of A. varifrons terminates in a blotch. Little material of A. varifrons in good condition is available for comparison, but thus far, it appears as though Agromyza sp. 1 is more pruinose on the frons and abdomen, the ocellar triangle is paler outside of the tubercle, and the acrostichal seta is shorter (see above key). The third dorsocentral may also prove to be consistly shorter; a single specimen of A. varifrons has been examined that shows that this seta is indeed present (not absent, as noted in Lonsdale, 2021), with the seta being 60% as long as the first (50% as long in Agromyza sp. 1).</p></div>	https://treatment.plazi.org/id/038B879BFFF3745312C0DCC248DBB1DF	Public Domain	No known copyright restrictions apply.

Eiseman &amp; Blyth (2022) reported “shotholes” from adult host-feeding on Q. prinoides Willd., but we have not seen larval mines on this host. See Comments regarding the suitability of hosts not confirmed by rearing.</p><p>Leaf mine. A brownish blotch, or sometimes irregularly linear; see Eiseman &amp; Lonsdale (2018, including Figs. 81–82).</p><p>Puparium. Brown; formed outside the mine.</p><p>Phenology and voltinism. Larvae mine in new, expanding leaves in spring. Occupied mines have been found in early to mid-March in Louisiana and Florida. Larvae have been collected in mid-April in North Carolina and Oklahoma, mid-May in Illinois, early to mid-June in Massachusetts and Rhode Island, and late June in Michigan’s Upper Peninsula, with reared adults emerging 16–33 days later (Eiseman &amp; Lonsdale 2018). What this species does for the rest of the year needs further investigation; we have never found larvae or recently vacated mines after June, and puparia kept longer than a month have invariably produced parasitoids. In Maine, LaBonte &amp; Lipovsky (1967) reported larvae normally mining in June, with reared adults emerging in mid-July; they likewise reared only parasitoids from overwintered puparia. However, when they artificially extended the availability of new oak foliage by clipping the leaves of small trees in late June, females continued to make host-feeding punctures as long as new leaves were available, and larvae were found mining in these leaves into the first week of August. They noted that this phenomonon suggests J. viridula may use other hosts later in the season, when young oak leaves are not normally available. Spencer (1969a) listed a specimen caught in Nova Scotia on 1 August and one caught in Ontario on 7 September; other Canadian material listed by him and Lonsdale (2021) was collected between late May and early July.</p><p>Distribution.

Although only the new host family Juglandaceae is confirmed by rearing, Betulaceae and Myricaceae are likewise in the order Fagales (as is Fagaceae, the previously known host family), and thus are equally plausible hosts for this fly. Myricaceae is recorded based on a single aborted mine, however, so there is currently no evidence that J. viridula can complete development on hosts in this family. Although we have seen numerous examples of mines on Betula spp., most of them have been clearly aborted. On 2 June 2024, CSE collected mines on B. populifolia in his yard in Northfield, Massachusetts, where J. viridula mines were abundant on nearby oaks. One of these mines on B. populifolia contained a live larva, but it abandoned the leaf in its second instar. On the other hand, mines have been found on B. papyrifera in areas of Minnesota and New Brunswick where oaks are scarce (M. Zappa and J. Klymko, in litt.). A larva found mining a leaf of B. papyrifera in Minnesota successfully formed a puparium, but it proved to be parasitized. The mines found on Acer ( Sapindales: Sapindaceae) in Pennsylvania were all aborted, and this is surely not a suitable host.</p><p>The more compact shape, different frass pattern, presence of a hole in the leaf associated with the oviposition site, and (sometimes) presence of distinct secondary feeding lines distinguishes mines of J. viridula on Betula from those of Agromyza alnibetulae . Vacated mines of Eriocraniidae ( Lepidoptera), which likewise occur on Betula, Castanea, Quercus, and Juglans, can be quite similar to those of J. viridula but can be recognized by the more solid, stringy frass.</p></div>	https://treatment.plazi.org/id/038B879BFFF2745012C0DC1A4946B5F3	Public Domain	No known copyright restrictions apply.

Melanagromyza arcana is readily characterized by a shining greenish ocellar triangle that reaches to the anterior ors and a glossy greenish scutum. These features, combined with the shallow gena, will key specimens to M. ruelliae Spencer, a species known from the southeastern states into the Bahamas and Guadeloupe as a seed head feeder on Acanthaceae . This latter species differs in having a blue and green metallic shine on the ocellar triangle, the distal margin of the hypandrium is enlarged into an exceptionally long apodeme, the basiphallus is long and asymmetrical, and the shapes of the mesophallus and distiphallus differ (see Spencer &amp; Steyskal (1986: Figs. 28, 29). The differences in the genitalia do not suggest a relationship between the two species.</p></div>	https://treatment.plazi.org/id/038B879BFFF0745712C0DB9F4CDBB2E5	Public Domain	No known copyright restrictions apply.

King, adult ♀ on Phlox paniculata (iNat 83110692) .</p><p>Etymology. This species is named for CSE’s daughter, Ayla B. Eiseman. The holotype was the first agromyzid CSE collected after her birth in February 2023, and the type locality is her birthplace. The specific epithet is to be treated as a noun in apposition.</p><p>Host. Polemoniaceae: Phlox paniculata L.</p><p>Larval biology. (Figs. 116, 117) In spring, eggs are inserted in leaf blades, on which the females also use their ovipositors to make numerous host-feeding punctures. The larva forms a narrow, yellow-green, linear mine in the leaf blade, leading into the midrib, through which the larva moves into the stem. It then bores downward in the pith, producing a narrow tunnel.</p><p>Puparium. (Fig. 19) Elongate, straw-colored, with prominent black posterior spiracular horns. We have found a few parasitized or otherwise nonviable puparia in the pith of overwintered stems, but at least some larval tunnels extend to the stem bases, and we suspect puparia are normally formed in the roots. The puparium of the reared specimen was not observed (see Comments).</p><p>Phenology and voltinism. The holotype emerged in spring from an overwintered stem. Ovipositing and host-feeding females are present in late May in Massachusetts (mid-June in Ontario, assuming the photographed female in fact represents this species). Leaf mines are evident as early as 28 May, and extensive pith boring has taken place by 12 July. Since adults are present only in spring (the plants are in CSE’s yard and are checked regularly), we believe this species to be univoltine.</p><p>Distribution. USA: MA, [NY; Canada: ON].</p><p>Adult description. (Figs. 17, 18) Wing length 2.6 mm (♂), 2.5 mm (♀). Length of ultimate section of vein M 4 divided by penultimate section: 0.6. Eye height divided by gena height: 4.5–4.6. First flagellomere small, rounded. Lunule slightly wider than high, with shallow medial groove ventrally. Frons strongly curved ventrally. Orbital plate narrowed anteriorly, wider medially at level of ors and posterior ori where it is about 18% width of frons; slightly visible when viewed laterally. Ocellar triangle nearly reaching anterior margin of frons, sides somewhat concave. Face concave, with shallow carina on ventral half. Gena strongly narrowing anteriorly. Clypeus rounded anteriorly.</p><p>Chaetotaxy: Three ori, with large gap between second ori and posterior ori; anterior two ori nearly flat on frons; two ors. Orbital setulae in up to three rows at widest part of orbital plate, outer row reclinate and exclinate, inner rows mostly erect to proclinate. Ocellar and postvertical setae almost as long as ors. Eye virtually bare in female, male with ommatrichia sparsely scattered on eye, those in dense dorsomedial patch about as long as orbital setulae. Genal setae strong, directed anteriorly, about half length of vibrissa. Two strong dorsocentrals, with second seta about ⅘ length of first. About 12 irregular rows of acrostichal setulae reaching level of first dorsocentral. Anepisternum and katepisternum with several additional smaller setae. Mid tibia with one posteromedial seta.</p><p>Coloration: Setae black. Body black with faint green metallic shine only distinctly evident on notum and abdomen. Wing veins brownish-yellow. Calypter white.</p><p>Genitalia: (Figs. 261–265) Epandrium with inner posteroventral spine, fully fused to surstylus. Surstylus angled anteriorly, about half height of epandrium, distal margin broad and mostly straight, and inner-distal margin with two rows of tubercle-like setae. Cercus well-developed. Hypandrium with exceptionally long, tapering apodeme. Phallophorus narrower at base, thin and bulging distoventrally; separated from mesophallus by approximate length of basiphallus. Basiphallus U-shaped, narrowest dorsally and with margins irregular. Mesophallus rounded, narrowed at base, inserted ventrobasally on distiphallus, and with base projecting further basally past base of distiphallus. Distiphallus with one pair of narrow ventral tubules flanking mesophallus that are positioned basally on segment; seen laterally, shape relatively stout with dorsal and ventral surfaces parallel, dorsal chamber long, extending almost to apex of segment and with spinulose pad on inner-dorsal surface that is narrow but relatively high; dorsomedial tubule largely concealed within large dorsal chamber, curved ventrally and swollen apically; seen ventrally, distiphallus with narrow rounded base that gradually expands to widest point before apex with laterodistal surface more thickly sclerotized; one pair of small, dark sclerotized pads past mesophallus that are narrowed and converging anteriorly. Ejaculatory apodeme well-developed with irregular distal margin and faint medial rib; sperm pump with strong, dark transverse sclerite that is upturned at ends.</p><p>Comments. The rearing of this species was accomplished by marking Phlox plants on which larval leaf mines were visible, and then digging up two marked plants the following April and placing them in transparent plastic bags. The bags were closed at the tops with twist-ties, brought indoors, and checked regularly for emerging insects, which also included adults of a chloropid fly ( Rhopalopterum sp.) whose larvae likewise inhabit P. paniculata stems (three larvae were found feeding together at the base of one stem, not associated with distinct, narrow tunnels like those produced by the Melanagromya larvae). Another Phlox stem borer, Melanagromyza phloxicaulis sp. nov., is described below. It has so far only been associated with P. pilosa L.; there is no indication that its larvae start out as leafminers, and its phenology is different, with adults emerging in early summer from the current year’s stems.</p><p>Melanagromyza ayla is characterized externally mostly on the basis of head morphology. There are five fronto-orbitals, of which the anterior one or two setae are distantly separated from the posterior ones, and the posterior three setae are found within a thickened region of the orbital plate. The ocellar triangle nearly reaches the anterior margin of the frons and the sides are shallowly concave, the clypeus is rounded and the genal setae are strong and directed anteriorly. Like many other Melanagromyza, this species is also very dark with a green metallic shine, the calypter is white, the eye is longest dorsally and the male has a dense dorsomedial patch of ommatrichia, there are two strong dorsocentrals and only one posteromedial seta on the mid tibia.</p><p>In Spencer &amp; Steyskal (1986), this species will key to Melanagromyza longensis Spencer, which differs in having eight rows of acrostichal setulae and an apically tapering distiphallus (Spencer &amp; Steyskal 1986: Figs. 56, 57). The male genitalia of M. ayla are distinct in having a distiphallus that is narrow basally and widest subapically (not widest near the base), and seen laterally, the dorsal chamber extends almost to the end of the segment, the paired tubules are basal on the segment, and the dorsum of the distiphallus is parallel to the venter; the hypandrium also has a very long apodeme.</p></div>	https://treatment.plazi.org/id/038B879BFFF7745512C0D85D49DBB55F	Public Domain	No known copyright restrictions apply.

(Fig. 20) Wing length approximately 2.3–2.4 mm (♂), 2.5–2.7 mm (♀). Length of ultimate section of vein M 4 divided by penultimate section: 0.6–0.7. Eye height divided by gena height: 4.3–6.9. First flagellomere small, rounded. Lunule wider than high, with faint medial groove. Face with small, shallow carina that is only obvious dorsally. Body subshining, ocellar triangle slightly more shining; frontal vitta minutely textured. Orbital plate widened medially at level of posterior three fronto-orbitals, almost ¼ width of frons at widest point. Eye with sparse ommatrichia; female eye only slightly more pilose dorsomedially, male with small dorsomedial region densely pilose with hairs longer than orbital setulae. Clypeus U-shaped with anteromedial region slightly thicker, anterior margin sometimes nearly straight (including in holotype and one female).</p><p>Chaetotaxy: Two ori, two ors; ori slightly more than half length of ors, thinner, and strongly incurved, nearly flat on frons; posterior three setae closely spaced posteriorly, leaving large gap between anterior and posterior ori; distance between anterior ors and posterior ori sometimes slightly greater than distance between ors. Orbital setulae erect to proclinate, in up to three scattered rows at widest point. Two strong dorsocentrals with anterior seta about ⅘ length of posterior. Acrostichal setulae in about 10 irregular rows, reaching level of posterior dorsocentral. Anepisternum with two subdominant setae, katepisternum with one. Mid tibia with one or two posteromedial setae.</p><p>Coloration: Setae black. Body mostly dark brown. Outer margin of orbital plate (less so posteriorly), anterior region of vitta and gena with beige tint. Notum and abdomen with faint greenish metallic shine. Sides of notum with paler brown patches. Mediotergite darker brown. Wing veins light brown.</p><p>Genitalia: (Figs. 266–270) Epandrium fused to surstylus; with posteroventral spine. Surstylus angled anteriorly with distal margin straight and slightly produced on posterior corner; inner-anterior and -distal margins with tubercle-like setae that are longer posteriorly (these easily viewed laterally). Hypandrium broad, with distal margin produced as long, narrow apodeme. Phallophorus narrower than high, venter past base weakly sclerotized and broadly rounded. Basiphallus U-shaped, close to both phallophorus and distiphallus. Mesophallus slightly narrowed basally at point of insertion with distiphallus; raised from surface of distiphallus; level of base slightly distal to that of distiphallus. Distiphallus relatively short and stout; one pair of narrow tubules flanking mesophallus; dorsal chamber high, longer than high with opening small, constricted, enclosing one pair of long, minutely spinulose pads; sides mostly parallel, anterodorsal region slightly expanded; ventral plate on distal half of segment short, almost as long as medial tube. Ejaculatory apodeme with darker base and stem, medial rib weak distally; blade pale, atrophied on one side; sperm pump with dark, narrow transverse sclerite upcurved at ends.</p><p>Comments. Typical of species in the Melanagromyza virens group, M. blephiliae has a broadly rounded anterior region of the frons, the anterior ori is distant from the other fronto-orbitals and the male eye has a dense dorsomedial patch of relatively long ommatrichia. Like many species in the group, the posterior tubercle-like setae are also elongate, readily viewed laterally and on a slight extension of the posteroventral corner of the surstylus.</p><p>Melanagromyza blephiliae is most similar to one of the most abundant members of the M. virens group, M. virens (Loew), which is widespread in eastern North America and British Columbia on various Asteraceae genera (see below). This more abundant species differs, however, in using hosts belonging to a different plant order, there are sometimes different colors on the notum and abdomen, the acrostichal setulae are in 8 rows, the orbital plate is usually up to ⅓ the width of the frons, the surstylus is shorter but the posterior extension and its spines are larger, the mesophallus is further suspended posteroventrally, the ventral surface of the distiphallus is flat, and the dorsal chamber of the distiphallus is smaller with a strongly constricted apical opening.</p></div>	https://treatment.plazi.org/id/038B879BFFF5745412C0DCC34C70B42B	Public Domain	No known copyright restrictions apply.

Specimens without this fore tibial seta will key closest to M. vectabilis Spencer in Spencer &amp; Steyskal (1986), but the eye of that Floridian species is more conspicuously setulose, the gena is ⅒ the height of the eye, and the dorsal chamber of the distiphallus is larger and more elongate (Spencer &amp; Steyskal 1986: Figs. 102, 103).</p><p>The male genitalia of Melanagromyza mikannula are not easily confused with those of other Eupatorieae-feeding species. Additional characters differentiating it from other congeners are the presence of posterobasal to -medial spines on a relatively elongate, incurved surstylus, which also has a mix of regular and tubercle-like setae along the distal margin; an O-shaped basiphallus; and very narrow lateral tubules on the distiphallus, which also has a short, thick ventral plate, and relatively elongate dorsal chamber with a broad, open distal margin and a raised spinulose pad internally.</p></div>	https://treatment.plazi.org/id/038B879BFFFB745A12C0DF8F49C7B55F	Public Domain	No known copyright restrictions apply.

Melanagromyza phloxicaulis is best diagnosed by the unusual curved and contorted phallus that is dorsally sectioned into small lobes. The slightly produced, angled surstylus and short space between the phallophorus and distiphallus are also characteristic.</p><p>Externally, the new species keys to Melanagromyza angelicae using Spencer &amp; Steyskal (1986), but that species differs in having fewer rows of acrostichal setulae, it is slightly larger, the ommatrichia on the eyes are sparser, the orbital plate is flatter, and the male genitalia are quite different (Lonsdale 2021: Figs. 257–260). The morphology of the new species is actually more similar to M. vernoniana Steyskal, which is clearly related (see Lonsdale (2021: Figs. 309–317)).

Caught adults have been collected in late April (VA), May (IL, MD, VA), early June (OK, VA), and late June (ON, VT) (Lonsdale 2021).

However, in Missouri, adults have emerged from 3 to 25 August from stems collected in late July, and in Illinois, Indiana, and Missouri, reared adults are labeled with late October dates that seem to be emergence dates, but since just one date is given it is possible these are collection dates (Lonsdale 2021). According to Spencer &amp; Steyskal (1986), the holotype of M. verbesinae Spencer (now a synonym of M. vernoniana) emerged 21 March 1970 from a stem collected in Ohio on 5 May 1969. Lonsdale (2021) lists a Missouri specimen labeled as having emerged in September 1930 from material collected 9 September 1929.

On Achillea and Erigeron, larvae of the spring generation girdle the stem by boring in a spiral close to the surface once or twice, then feed downward deeper in the stem tissue. The portion of the stem above the girdle wilts and droops conspicuously. On Vernonia baldwinii, the larvae bored within stem galls of Neolasioptera vernoniae (Beutenmuller) ( Cecidomyiidae), probably killing the original inhabitants (M.W. Palmer, in litt.).</p><p>Puparium.

The rearing from Vernonia baldwinii in Oklahoma suggests a univoltine life cycle, with larvae or puparia present in galls collected in late June and adults not emerging until the following spring. In Iowa, larvae that cause stems of Achillea and Erigeron to wilt by 1 June form puparia by mid-June and emerge as adults beginning in early July. This suggests there may be a second generation, but so far the puparia JBV has found overwintering in senescent stems of these plants have been either empty (from adults emerging during the growing season) or parasitized. In Florida, adults have emerged from stems in late June and mid-July, and adults have been collected in late March and early October (Spencer &amp; Stegmaier 1973).</p><p>Distribution.

The only previously published record we have seen of a Melanagromyza species emerging from galls of another insect is that of Plakidas (1982), who reported rearing M. matricarioides Spencer from floret galls of Asphondylia helianthiglobulus Osten Sacken ( Diptera: Cecidomyiidae) on Rudbeckia laciniata L. ( Asteraceae). The agromyzid involved has been reidentified as M. virginiensis Spencer (Lonsdale 2021), and the gall inducer was actually A. rudbeckiaeconspicua Osten Sacken (J. Plakidas, in litt.).

The specific epithet combines the host plant (an aster, in the broad sense) with the Latin costa, “rib,” referring to the larval habit of mining in the leaf midrib.</p><p>Hosts. Asteraceae: [ Symphyotrichum ciliolatum (Lindl.) Á.Löve &amp; D.Löve], S. laeve (L.) Á.Löve &amp; D.Löve, [ S. oolentangiense (Riddell) G.L.Nesom, S. puniceum (L.) Á.Löve &amp; D.Löve]. The host of the Iowa female was either S. shortii (Lindl.) G.L.Nesom or S. urophyllum (Lindl.) G.L.Nesom. The hosts photographed in Iowa in 2017 and 2019 were either S. cordifolium (L.) G.L.Nesom or S. drummondii (Lindl.) G.L.Nesom.</p><p>Leaf mine. (Figs. 129–131) The larva feeds in the petiole and basal portion of the midrib. Sometimes the mined area turns brown on both sides of the leaf, but often the mining and discoloration are only evident on the underside.</p><p>Puparium. (Figs. 28, 29) Both whitish and blackish puparia have been observed, although we have not confirmed that the latter are viable; formed within the petiole and mostly or entirely concealed by leaf tissue. Prior to pupation, the larva sometimes forms a ~ 0.8 mm translucent “window” in the upper epidermis (Fig. 129), through which the anterior spiracles of the puparium project.</p><p>Phenology and voltinism. In Iowa and Minnesota, mines have been collected in late June and mid-July, with adults emerging from mid-July to early August. Puparia of what we presume to be the overwintering generation have been found beginning in late August.</p><p>Distribution. USA: IA, MA?, [ME, MN].</p><p>Adult description. (Fig. 27) Wing length approximately 1.6 mm (♂), 1.9 mm (♀). Length of ultimate section of vein M 4 divided by penultimate section: 0.8–1.0. Eye height divided by gena height: 4.6–5.2. First flagellomere small, rounded; distal margin with slightly longer hairs. Orbital plate not distinct, narrow, widening at base of setae. Cheek narrow. Ocellar triangle reaching level of anterior ors. Frons minutely textured, especially on vitta, and slightly more shining around tubercle. Lunule shallow, wider than high, with central furrow. Face with shallow carina ventrally, and with shining, smooth, ovate medial bulb slightly wider than flat section between antennae. Vibrissal angle approximately 60°. Clypeus with long, narrow anteromedial process with distal margin straight and corners slightly produced. Notum dusted with grayish-brown pruinosity.</p><p>Chaetotaxy: Two ori (anterior seta nearly flat on frons) that are slightly more closely spaced than ors; two ors. One row of reclinate orbital setulae. Postvertical seta subequal to ors; ocellar seta slightly smaller. Vibrissal fasciculus well-developed, gently upcurved with setae separating apically. Two strong dorsocentral setae, anterior seta slightly shorter. Approximately six to eight rows of acrostichal setulae ending behind second dorsocentral, with only one pair of terminal setulae. Anepisternum and katepisternum with smaller additional seta. Mid tibia without posteromedial setae in male, one small seta present in female past midpoint.</p><p>Coloration: Setae black; setulae with paler brown shine. Wing veins light brown. Calypter margin whitish, hairs dark brown. Body dark brown with sides of scutum and pleuron slightly paler. Female abdomen with faint golden/ greenish metallic shine.</p><p>Genitalia: (Figs. 281–284) Epandrium fused to surstylus. Surstylus small, rounded, not much longer than wide; with two to three scattered rows of tubercle-like setae on inner surface. Cercus well-developed. Hypandrium broadly rounded basally, subtriangular with small apodeme. Phallophorus narrowest at base, expanded and produced anteroventrally, separated from mesophallus by its own length. Basiphallus sclerotized dorsobasally, with left branch atrophied and right branch well-developed, narrow and of subequal width along most of length. Mesophallus not much longer than high, rounded, inserted ventromedially on distiphallus; base not produced past base of distiphallus. Distiphallus (ventral view) widest medially, apically with one pair of large raised carinae between two narrow, welldelimited lobes; internally spinulose lateromedially and with smaller to rounded internal spinules distolaterally and dorsoapically; seen laterally, basal half broadly open dorsally with strong dark shelf emerging at midpoint of segment, and right distal surface nearly circular. Ejaculatory apodeme not recovered.</p><p>Comments. The Massachusetts specimen was reared from a mine identical with that of Ophiomyia quinta Spencer. An unseen O. astericosta mine in the rearing vial does not seem to be a possible explanation, because the collection consisted of a single mined leaf, which was observed to have an intact O. quinta puparium at the time of collection, and this was empty when the adult fly appeared. An inadvertent switching of specimen labels also does not seem likely, since we have no record of having reared another male from an O. astericosta type mine. We are nevertheless reluctant to accept that O. astericosta can produce an O. quinta type mine until this rearing can be repeated.</p><p>Ophiomyia astericosta and O. sequentia are two new species that are highly similar in external appearance. Both have brown calypter hairs, two ori and ors, a vibrissal angle of about 60°, and a strong fasciculus. Ophiomyia sequentia differs in being slightly larger (wing length 2.0 mm), having an apically pointed (not frayed) vibrissal fasciculus, and a slightly wider facial bulb that is barely wider than the flat section dorsal to it between the antennae. Internally (Figs. 305–309), the surstylus of O. sequentia is narrower with an oblique line of tubercles along the inner surface, the phallophorus is narrower, and the basiphallus is longer, reaching a much narrower mesophallus that is inserted into a shorter, rounded distiphallus. Using Spencer &amp; Steyskal (1986), these species may key to O. texana (Malloch), but the distiphallus of that species is much larger with a narrow basal process.</p><p>Ophiomyia coniceps (Malloch), which occurs on Antennaria Gaertn. and Sonchus L. ( Asteraceae), is also quite similar in appearance and requires examination of minutiae of the male genitalia for morphological diagnosis. Ophiomyia coniceps differs in that the fasciculus is usually sharply pointed, the basiphallus is longer, the mesophallus is slender, the distiphallus more bulbous apically and the basal half more evenly narrowed, the inner shelf (visible at the midpoint in lateral view) is slightly angled, and the small ventrodistal flap emerging from the distiphallus is bent to the side, not distally. The inner surface is also far less spinulose, having far fewer wider, shallower bumps. In lateral view, a small, weakly sclerotized fold floating under the distiphallus is also evident in O. astericosta, and not in O. coniceps .</p></div>	https://treatment.plazi.org/id/038B879BFFFD744312C0DAF74904B693	Public Domain	No known copyright restrictions apply.

(Fig. 143) Whitish, with little or no evident frass; sometimes beginning as a linear mine on the lower surface of the leaf blade; primarily extending along the upper surface of the midrib, with irregular excursions into the blade. Frass accumulates in the larva’s resting place at the base of the midrib. The larva may mine down the petiole of the original leaf and into the petiole of a second leaf (Eiseman et al. 2019, including Fig. 29; Eiseman &amp; Blyth 2022).</p><p>Puparium. (Fig. 37) White to yellowish-white (reportedly sometimes black in Europe), on the underside of the leaf, with the anterior spiracles projecting through the epidermis.</p><p>Phenology and voltinism. Multivoltine. In North Carolina, mines have been collected in April, May, June, and July, with adults emerging in mid- to late May, early to late June, and late July or early August (Eiseman et al. 2019). The single known Massachusetts specimen emerged in late September from a leaf collected earlier that month (Eiseman &amp; Blyth 2022).</p><p>Distribution. USA: MA, NC; Africa; Asia; Europe (Eiseman et al. 2019; Eiseman &amp; Blyth 2022).</p><p>Comments. This is the species discussed by Eiseman et al. (2019) as Ophiomyia sp. 2, now confirmable as O. beckeri based on examination of the male genitalia of newly reared specimens (Figs. 40, 285–289). In Spencer &amp; Steyskal (1986), this species will key to several Californian species in the O. jacintensis species group—specifically, O. shastensis Spencer, O. jacintensis Spencer, and O. yolensis Spencer. These Californian species share three ori and a far different phallic morphology, including a short, ring-like basiphallus and a small, simple, bulb-like distiphallus.</p><p>Ophiomyia beckeri instead belongs to a species group characterized by a flat face and a single vibrissa, sparse ommatrichia on the eye of both sexes, a clypeus that is not narrowed anteriorly and a mid tibia with two posteromedial setae. Internally, the distiphallus is large and segmented, and there is a characteristic basiphallus consisting of a floating left lateral sclerite connected to the right sclerite by a narrow ventral bridge.</p><p>In the Nearctic, this group additionally includes Ophiomyia congregata (Malloch), O. frosti Spencer, O. lactucae sp. nov., O. pulicaria (Meigen) [Holarctic], and possibly O. decima Spencer. Other species with a similarly structured basiphallus are the Old World pests O. phaseoli (Tryon) and O. spencerella (Greathead), but these smaller species have the phallus differently structured and there are no setae medially on the mid tibia, and are likely unrelated. European species include O. adunca Guglya, O. cunctata (Hendel), and O. vimmeri Černý. European species showing more similarity to O. phaseoli include O. inaequabilis (Hendel) and O. improvisa Spencer. Although this species group has been named in the past after O. cunctata and O. inaequabilis, it seems more reasonable to reapply the name “ O. pulicaria group” as the nominal species has a phallus fairly “typical” of most species confidently placed here, and it occurs in multiple biogeographic regions.</p></div>	https://treatment.plazi.org/id/038B879BFFE3744212C0DF8F4B50B623	Public Domain	No known copyright restrictions apply.

(Fig. 132) According to Spencer &amp; Stegmaier (1973), the larva feeds mainly along the midrib, with offshoots along lateral veins. Our California specimens were reared from pale green, narrow, linear mines, which meandered across the leaf blade, following the midrib and lateral veins for short stretches. There were a few very short branches out from the main linear track; these and a few other small patches were white instead of green. Intermediate forms between these two mine types exist, at least sometimes beginning with a long, whitish linear portion on the lower surface.</p><p>Puparium. Whitish; formed within the leaf. In the examples we have seen, the puparium is well concealed within the thick mesophyll, externally discernible only by a small, round, whitish “window” in the upper epidermis where the palisade cells have been thoroughly consumed, through which the anterior spiracles protrude.</p><p>Phenology and voltinism. Probably multivoltine; in Florida, adults have emerged from collected mines in mid-April and have been caught in mid-October (Spencer &amp; Stegmaier 1973). Our California specimens emerged in late May from mines collected earlier that month, and the Texas specimen emerged in mid-December from a mine collected in late November.</p><p>Distribution. USA: [AL], *CA, FL, [LA, MS, TX; Bahamas]; Barbados; [Bermuda]; Brazil; Guadeloupe; [Haiti; Jamaica; Puerto Rico]; Saint-Martin; Trinidad and Tobago; Venezuela; introduced in South Africa and Australia as a biological control agent (Monteiro et al. 2019).</p><p>Comments. Spencer &amp; Stegmaier (1973) discussed an “undescribed [ Ophiomyia] species forming long, narrow, pale greenish linear mines (Fig. 151) on Lantana camara, pupating in the leaf,” known from mines found in Florida and Venezuela. They concluded, “It is to be hoped that eventually males of this species can be reared, so that its status can be clarified.” The mines of our California specimens were quite similar to the one illustrated by Spencer &amp; Stegmaier, and we believe the latter is likewise attributable to O. camarae . Spencer &amp; Steyskal (1986) suggested that O. parvella (Spencer) might be responsible for these linear mines, but that species is very similar to the Tilia L. ( Malvaceae) gall inducer O. tiliae (Couden) and possibily synonymous with it (Lonsdale 2021).</p></div>	https://treatment.plazi.org/id/038B879BFFE2744212C0DF1F4CA7B04F	Public Domain	No known copyright restrictions apply.

(Eiseman &amp; Lonsdale 2018).</p><p>Leaf mine. Linear, typically branching and emanating from the petiole; see Eiseman &amp; Lonsdale (2018, including Fig. 86).</p><p>Puparium. Whitish to dark brown; formed within the petiole or leaf blade, with the anterior spiracles projecting through the upper epidermis.</p><p>Phenology and voltinism. All rearings from Antennaria have involved adults emerging (indoors) between January and April from overwintered puparia (Eiseman &amp; Lonsdale 2018). The earliest date that presumed O. coniceps mines have been observed on the current season’s leaves is 18 July (Pennsylvania). The holotype was reared from Sonchus in Utah, and the date of 14 August on the label is apparently the emergence date. Adults have mostly been collected in spring, with dates ranging from 7 May (Indiana) to 1 July (Delaware) in the USA (Lonsdale 2021), and as late as 21 July (Ontario) in Canada (Spencer 1969a). But for the date on the holotype’s label, this species would seem to be univoltine.</p><p>Distribution. USA: [AL, AR, CT], CA, DE, [IA], IN, LA, MA, [MD], *MO, [NY, OH], OK, [PA], UT, VA, [WI]; Canada: BC, MB, ON, QC, SK (Eiseman &amp; Lonsdale 2018; Lonsdale 2021).</p><p>Comments. As discussed by Eiseman &amp; Lonsdale (2019), mines of the closely related Antennaria feeder Ophiomyia antennariae Eiseman &amp; Lonsdale do not seem to differ consistently from those of O. coniceps . So far O. antennariae is known only from Alabama, and if it proves to be more widespread, the host and distribution records for O. coniceps that are based only on leaf mines will have to be discarded.</p></div>	https://treatment.plazi.org/id/038B879BFFE0744012C0DEE64B8FB233	Public Domain	No known copyright restrictions apply.

First flagellomere small, rounded; distal margin with slightly longer hairs. Ocellar triangle reaching to level of anterior ors or posterior ori. Vitta minutely textured. Orbital plate narrow, faintly delimited, narrowest anteriorly. Lunule shallow, wide, without medial groove. Lower half of face with shallow carina, dorsum with ovate bulb that is slightly wider than space between antennal bases. Vibrissal angle about 60°. Cheek narrow. Clypeus with narrow anteromedial extension that has corners slightly produced. Notum with light dusting of pruinosity, almost shining.</p><p>Chaetotaxy: Two ori (anterior seta almost flat on frons), two ors. One row of orbital setulae. Postvertical and ocellar setae subequal to fronto-orbitals (slightly longer in Solidago -reared male) but thinner, with ocellar slightly shorter. Vibrissal fasciculus well-developed, curved upward; Oclemena -reared male with vibrissal setae separating apically, appearing “frayed”. Two strong dorsocentral setae, with second slightly shorter. Eight rows of acrostichal setulae, ending in one pair of setulae behind second dorsocentral. Katepisternum sometimes with extra smaller seta. Mid tibia with one posteromedial seta (none in tentatively identified female from Connecticut).</p><p>Coloration: Setae black.

Mesophallus narrow, slightly curved, inserted past midpoint of distiphallus; base of distiphallus extending far past base of mesophallus. Distiphallus very large, in ventral view appearing coffin-shaped with rounded apex and narrowed base, and with ventral sulcus with swollen margins that are produced as small carinae; lateral surface internally with pointed ridges that may be short to long and branched; in lateral view, surface appearing bumpy, dorsum open on distal ⅗ with short central process and dorsoapical tubule emerging from within cavity. Ejaculatory apodeme well-developed, with pale asymmetric blade that extends along one side of long stem; sperm pump with strong transverse sclerite that is upturned at ends.</p><p>Comments. While externally indistinguishable from most Ophiomyia with a fasciculus on a 60° vibrissal angle, the phallus of this species is unique and highly diagnostic, being large and coffin-shaped in ventral view.</p><p>Five entedonine eulophid wasps (CSE8963, CNC, iNat 323802117) emerged from the puparium collected in Vermont.</p></div>	https://treatment.plazi.org/id/038B879BFFE0744712C0DB2E4891B2DB	Public Domain	No known copyright restrictions apply.

(Williams &amp; Steck 2014: Figs. 4–5) Silvery-whitish; long, narrowly linear, sometimes becoming irregular or spiral-shaped; frass often not evident, but sometimes visible as fine, dark grains and short strips. Williams &amp; Steck (2014) note that “often larvae cross to the lower surface and continue to feed until they mature.” Location of pupation varies, but mature larvae often appear to occur towards the paler, concealed base of the leaf or the dorsal root surface.</p><p>Puparium. Pale brownish, not strongly segmented; posterior spiracles dark brown with pores in one or two irregular rows in a shallow arc. Pupation internal with anterior spiracles protruding through leaf surface (Williams &amp; Steck 2014: Fig. 6).</p><p>Phenology and voltinism. In North America, Williams &amp; Steck (2014) note “Multiple overlapping generations” annually, and while adults are present throughout the growing season, more concentrated adult emergence occurs in June and August.</p><p>Distribution. USA: [AL, AR, CA, CT, DC, DE], FL, [GA, IA, IL, IN, KS, KY, LA, MA], MD, [ME, MI, MN, MO], MS, [NC, ND, NE, NH, NJ, NY, OH, OR, OK], PA, [RI, SC], TN, [TX], VA, [VT, WA, WI, WV]; * Canada: [BC, NB], ON, [PE, QC]; Japan; Taiwan; Slovenia (Williams &amp; Steck 2014). Apart from our Ontario material, adult specimens have only been reported from Florida and Maryland; other USA records not in brackets are based on examined larvae and puparia.</p><p>Comments. These are the first specimens of Ophiomyia kwansonis, the daylily leafminer, from Canada. Its occurrence in Canada is unsurprising considering the speed at which this Japanese species has spread throughout the United States following its likely accidental introduction via the trade of its ornamental host, perhaps as early as 2006 (Williams &amp; Steck 2014). Additional Canadian records of leaf mines are documented on iNaturalist, with two observations in June 2020 near Toronto being the earliest. The first known example for each province is listed above under Photographed mines (as well as the first photographed mine for each US state not listed by Williams &amp; Steck (2014)), with observations in 2022 from New Brunswick and Prince Edward Island, and in 2023 from British Columbia, Quebec, and Nova Scotia.</p><p>One male specimen of Opius ( Braconidae) was reared from a larva collected at the same locality as the reared flies (coll. 10.vii.2021, em. 8.viii.2021, CNC1905436). Other reared parasitoid Hymenoptera of this invasive species are mentioned in Williams &amp; Steck (2014), but these specimens were not identified at the time of publication. The specimen was identified by J. Fernandez-Triana (CNC), who noted that Opius is a large genus in need of global revision, with 180 described species in North America alone. No Opius has been reared from Ophiomyia kwansonis previously, so there is the possibility that the association is new.</p></div>	https://treatment.plazi.org/id/038B879BFFE5744412C0DCA74B0DB49B	Public Domain	No known copyright restrictions apply.

Frons smooth, subshining with ocellar triangle and orbital plate slightly shinier. First flagellomere small, rounded, distal margin with hairs slightly longer. Lunule shallow, about four times wider than high, with medial groove; pruinosity faintly yellowish. Face nearly flat, with very shallow carina and no bulb; sides curved inwards from ventral and lateral margins. Clypeus relatively broad, anterior margin wide and straight with corners distinct. Notum almost shining, with faint dusting of pruinosity. Body relatively large and robust.</p><p>Chaetotaxy: Two ori, sometimes with three on one or both sides; two ors; slightly wider space between posterior ori and anterior ors. Orbital setulae relatively numerous and thick, in one to two irregular rows, erect to slightly reclinate. Postvertical and ocellar setae subequal to fronto-orbitals but thinner. Genal setae relatively long and numerous, mostly curved outwards; shorter in female. Two strong dorsocentral setae, both anterior setae missing. Acrostichal setulae in approximately 12–16 scattered rows, reaching level of first dorsocentral. Anepisternum and katepisternum with two additional setae. Mid tibia with two or three posteromedial setae.</p><p>Coloration: Setae black. Body black. Wing veins light brown. Calypter margin dark brown; hairs dark brown with slight golden shine.</p><p>Genitalia: (Figs. 300–304) Epandrium anteroventrally fused to surstylus. Surstylus short, sides nearly straight and slightly converging, apex broadly rounded; inner surface with four to five irregular and anteriorly diverging rows of tubercle-like setae. Cercus well-developed. Hypandrium longer than wide with sides gently curved; apex with apodeme longer than wide, gradually narrowing. Phallophorus dark basally, narrowest subbasally; swollen distoventrally; separated from distiphallus by approximately its own length. Basiphallus consisting of two irregular plates that narrowly fuse ventrally, with left plate small and more distal in position, and right plate longer with base wrapping around shaft dorsally. Mesophallus subcylindrical, inserted into distiphallus past midpoint; small relative to large distiphallus, which extends far past base of mesophallus. Distiphallus large, vaguely divided into three sections; basal section fully enclosed past junction with middle section, longer than high, subovate with two rounded terminal processes (one much smaller than the other), almost half length of distiphallus, minutely pitted dorsally and minutely spinulose on inner surface ventrally; middle section short, as broad as basal section, shallowly spinulose ventrolaterally, with narrow sclerotized band circling right lateral surface, open dorsally and enclosing medial shelflike process; distal section open dorsally to expose dark tubule, somewhat twisted and bilobed ventrally, with inner surface spinulose on shallower left side and with irregular sclerotized bands on higher right side. Ejaculatory apodeme well-developed with large, minutely striated blade, dark medial rib that disappears past middle of blade; sperm pump with dark transverse sclerite upturned at ends.</p><p>Comments. This species was treated as Ophiomyia cf. frosti by Eiseman et al. (2021). We now consider O. frosti to be known only from the holotype (Spencer &amp; Steyskal 1986: Figs. 187, 188), collected in New York, with unknown host and larval biology. Ophiomyia frosti (specimens not available for the present study) appears to be related to the new species based on the morphology of the basiphallus and phallus, and in the general structure of the head, although the genal setae are “normal”, being shorter and sparser. A mine found on Lactuca serriola L. in Pennsylvania, with a larva present in mid-May (iNat 216575772), might represent either of these species.</p><p>Ophiomyia lactucae is readily characterized by an absence of the male facial keel and produced gena, it has an anteriorly broad, straight clypeus, strong genal setae that are relatively more numerous, and a large, segmented distiphallus. These characters readily associate it with O. congregata (Spencer &amp; Steyskal 1986: Figs. 184–186), which similarly mines in petioles, but in Nabalus . The latter species differs in having the genal setae straighter and more densely arranged beside the vibrissa, as opposed to being more sparsely arranged with their orientation outwards and more irregular. Ophiomyia congregata also has fewer rows of acrostichal setulae (about 10–12), specimens are very slightly smaller (2.4–2.6 mm), and the basal section of the distiphallus appears to be shorter (with a corresponding enlargement of the middle section) and without terminal processes.</p></div>	https://treatment.plazi.org/id/038B879BFFEB744A12C0DEE64CEAB5CF	Public Domain	No known copyright restrictions apply.

Spencer &amp; Steyskal’s (1986) record from “ Aster ” surely also refers to a Symphyotrichum species, and we presume their records from Solidago either represent O. maura or misidentified plants, as discussed by Eiseman &amp; Lonsdale (2018).</p><p>Leaf mine. (Figs. 142, 144) Pale green, narrowly linear with frass in widely spaced black lumps; see Eiseman &amp; Lonsdale (2018, as Ophiomyia parda Eiseman &amp; Lonsdale).</p><p>Puparium. Pale bluish-white, formed within the leaf, at the end of the whitish lower-surface portion of the mine (usually adjacent to the leaf margin).</p><p>Phenology and voltinism. Multivoltine. The holotype was collected as an adult in late May (ON; Spencer 1969a). Adults have emerged in early to mid-May (AR (Spencer &amp; Steyskal 1986), NC), early to late June (MA, NC, NY), early to mid-July (IA, MA, MI, WI), early to mid-August (ME, OH), and mid-September (MA), always from mines collected in the preceding month (Eiseman &amp; Lonsdale 2018).</p><p>Distribution. USA: AR, *IA, *MA, *ME, *MI, *NC, NY, *OH, *WI; Canada: ON (Spencer 1969a; Spencer &amp; Steyskal 1986). The previous New York record given by Spencer &amp; Steyskal (1986) is questionable since it refers to a specimen reared from Solidago, and their record from Pennsylvania is even more doubtful since it is based on a female reared from Solidago (see above under Hosts). Also see Comments.</p><p>Comments. Whereas the Iowa and North Carolina males match the original description of Ophiomyia quinta and the Michigan male matches the description of O. parda, the Massachusetts and New York males exhibit a mix of features and intermediate states otherwise characteristic of the two type series, including wing length, calypter color, and details of the distiphallus and mesophallus. As such, we now consider O. parda syn. nov. to be a synonym of O. quinta . No differences in leaf mine characteristics were observed among these specimens.</p><p>In the Distribution section above, we have not listed records that have not been confirmed by rearing, which include over 1300 observations of leaf mines posted to iNaturalist and BugGuide. These observations are exclusively on Symphyotrichum spp. and document a continuous distribution from southeastern Manitoba east through Michigan and southeastern Ontario to the Canadian Maritimes, south to central and eastern Texas, Louisiana, Mississippi, central Alabama and Georgia, and North Carolina. There is a single observation from eastern British Columbia on S. puniceum (iNat 190226249), and two similar mines have been found in the Sierras of California: one on S. bracteolatum (Nutt.) G.L.Nesom (iNat 92023840), and one on an undetermined “aster” (iNat 183760011). Mines with the characterstic frass pattern of this species have also been found in Florida on Ampelaster carolinianus (Walter) G.L.Nesom (iNat 153858524, 191972820).</p></div>	https://treatment.plazi.org/id/038B879BFFE8744F12C0DB674A8EB14B	Public Domain	No known copyright restrictions apply.

Eiseman, mine on Symphyotrichum puniceum (iNat 191981828).</p><p>Etymology. The specific epithet is a Latin word meaning “succession,” referring to the larval habit of mining a series of adjacent leaves.</p><p>Host. Asteraceae: Symphyotrichum puniceum (L.) Á.Löve &amp; D.Löve.</p><p>Larval biology. (Fig. 145) The larva forms a long, narrow, epidermal, linear mine, without evident frass, on the upper surfaces of several adjacent leaves. It moves from leaf to leaf downward through the stem. The holotype was reared from a larva that mined in five adjacent leaves, beginning at the apex of the plant, and the uppermost mined leaf was deformed, having been young and tender when it was mined. The only other observed mine appears to have involved four leaves, which probably constituted the plant’s apex at the time they were mined; all were deformed to some extent, progressively less so moving down the stem.</p><p>Puparium. (Fig. 38) The puparium of the holotype was formed just beneath the stem epidermis, ~ 5 cm below the lowest mined leaf, with its anterior spiracles protruding. When occupied it appeared pale green, closely matching the color of the adjacent stem tissue; the empty puparium is white.</p><p>Phenology and voltinism. Larvae are active in early spring; the only known specimen had already formed its puparium by 10 June, and the other observed mine, although found in September, was old and may also have been formed in spring.</p><p>Distribution. USA: MA.</p><p>Adult description. (Fig. 41) Wing length approximately 2.0 mm (♂). Female unknown. Length of ultimate section of vein M 4 divided by penultimate section: 0.8. Eye height divided by gena height: 10.0. First flagellomere small, rounded; distal margin with slightly longer hairs subequal to width of arista base. Orbital plate not distinct, narrow, widening at base of setae. Cheek narrow. Ocellar triangle reaching level of anterior ors. Frons minutely textured, especially on vitta, and slightly more shining around tubercle. Lunule shallow, wider than high, with central furrow. Face with carina shallow ventrally, with shining, smooth, ovate medial bulb approximately as wide as flat section between antennae (slightly narrower than in similar O. astericosta). Vibrissal angle approximately 60°. Clypeus with long, narrow anteromedial process with distal margin straight with corners slightly produced. Notum subshining.</p><p>Chaetotaxy: Two ori, relatively closely spaced with anterior seta nearly flat on frons; two ors. One row of orbital setulae. Postvertical seta subequal to ors, slightly longer than ocellar. Vibrissal fasciculus pointed, gently curved upwards. Anepisternum and katepisternum with smaller additional seta. Two strong dorsocentral setae, anterior seta only slightly shorter. Approximately six rows of acrostichal setulae ending behind second dorsocentral, with only one pair of terminal setulae. Mid tibia without posteromedial setae.</p><p>Coloration: Setae black. Wing veins light brown. Calypter margin whitish, hairs dark brown. Body dark brown with sides of scutum and pleuron slightly paler.</p><p>Genitalia: (Figs. 305–309) Epandrium fused to surstylus. Surstylus narrow, higher than long, with four irregular rows of tubercle-like setae directed obliquely across inner surface, ending on posterior margin with several longer, pointed setae. Cercus well-developed. Hypandrium with arms angled abruptly inwards, not rounded; terminal apodeme longer than wide. Phallapodeme narrow, only widened at base; seen laterally, narrowest at base, broadly expanded anteroventrally; narrowly separated from basiphallus by thickened membrane, separated from mesophallus by its own length. Basiphallus sclerotized dorsally for distance approximately half of that between phallophorus and mesophallus; right branch relatively broad, left surface with weakly sclerotized patch not easily viewed laterally; sclerotized sections on right and left surfaces weakly wrapping around venter as linear striations but not meeting. Mesophallus very narrow, slightly wider and rounded at base, venter slightly convex, continuing anteroventrally as very weakly sclerotized, raised carina; inserted ventromedially into distiphallus. Distiphallus relatively short, weakly spinulose along inner-lateral surface, spinules becoming shallower distally, becoming longer raised bumps on inner-apical surface that sometimes form shallow ridges; seen ventrally, elongate oval in shape with ends narrower; distally with ventral sulcus that divides one pair of weakly-differentiated lobes that end in slightly raised carinae; viewed laterally, most of basal half enclosed, midpoint with well-defined plate emerging from inner-ventral surface, broadly rounded distally with left side shallower. Ejaculatory apodeme well-developed with rounded, marginally clear blade; sperm pump small with strong transverse sclerotized plate upturned at ends.</p><p>Comments.

(Malloch 1913); * Cleomaceae: Cleome dodecandra L., C. houtteana Schltdl. “Spider bush” on the label of a Delaware specimen (Lonsdale 2021), which probably was not reared, likely refers to C. houtteana, whose common names include “spider flower,” “spider plant,” and “spider weed.” The plant we have tentatively identified as Mutarda nigra is a yellow-flowered mustard of disturbed ground and riverbanks (iNat 192430392, 192430583).</p><p>Larval biology. (Fig. 146) The larva forms a long, whitish or green linear mine, with black frass deposited in grains and short strips. Mines have so far been found exclusively on stems of Brassicaceae and on seedpods and pedicels of Cleomaceae . The specimen reared from Cakile edentula appeared in a vial along with 12 specimens of the leafminer Liriomyza brassicae (Riley), and its mine was not observed, but we have subsequently found Ophiomyia stem mines on this host.</p><p>Puparium. Whitish or black, formed at the end of the mine, just beneath the epidermis.</p><p>Phenology and voltinism. Multivoltine. Adult collection dates are 2 April (CA), 22 July (MB), 17 August (MB), 3 September (MB), and 12 September (DE). The holotype from Brownsville, TX was reared 27 January (Lonsdale 2021), and our specimens emerged in June (NC), early July (OK), late July (IA), early to mid-August (IA, PA), and late September to mid-October (MA). On 21 September 2018 in Oklahoma, M.W. Palmer (in litt.) noted that many of the new Cleome dodecandra seedpods had mines.</p><p>Distribution. USA: CA, DE, *IA, *MA, [ME], *NC, [NY], *OK, *PA, TX; Canada: MB; Bahamas (Lonsdale 2021). Unconfirmed records from Frick (1959) include CO, IL, IN, KS, MI, NM, SD, UT, WA, and WY.</p><p>Comments. Spencer &amp; Steyskal (1986) noted the slight morphological variability in the gena height and angle of Ophiomyia texana, and we have observed this as well. Some specimens have a more obliquely angled eye, a sharper genal angle of about 60° and a gena about 11–14% the height of the eye; others have a more vertically directed eye with a genal angle of abut 80°, and the gena is about 19% the height of the eye. The genitalia of these all appear to be uniform, however, including a particularly diagnostic process emerging from the basal surface on the right side that will be hidden by the mesophallus if viewed from the left side.</p></div>	https://treatment.plazi.org/id/038B879BFFED744D12C0DEE64C71B1E1	Public Domain	No known copyright restrictions apply.

Wing veins light brown. Calypter margin gray, hairs light brown with golden shine.</p><p>Genitalia: (Figs. 310–313) Epandrium fused to surstylus on anteroventral margin. Surstylus small, rounded, slightly tapering apically, slightly longer than wide; inner surface with up to four short rows of tubercle-like setae. Cercus well-developed. Hypandrium broadly rounded, without apodeme. Phallophorus constricted near base, broadest apically with dorsum shorter. Basiphallus sclerotized dorsobasally, with long right lateral arm nearly reaching level of distiphallus, and shorter, ill-defined left lateral arm. Mesophallus inserted medially into venter of distiphallus, subcylindrical, relatively short. Distiphallus venter continuing as carina distal to mesophallus along sulcus; seen ventrally, narrowing to rounded base, shallowly rounded at widest point past midsection, after which segment is abruptly narrowed, darker and minutely tuberculate; viewed laterally, segment shallow with vertical medial plate, basal ⅖ enclosed with base and distal ridge of dorsum sclerotized; lightly sclerotized tubule emerging past midpoint. Ejaculatory apodeme not recovered.</p><p>Comments. This species was discussed by Eiseman &amp; Blyth (2022) as Ophiomyia sp. 1 . It is the third Ophiomyia species, after O. euthamiae Eiseman &amp; Lonsdale and O. maura, to be reared from Euthamia, but so far these other two have only been associated with E. graminifolia (L.) Nutt. (Eiseman &amp; Lonsdale 2018). All confirmed mines of O. euthamiae have been primarily on the lower leaf surface, ending with a short upper-surface portion in which the black (overwintering) puparium was formed. On most hosts, O. maura mines are entirely on the upper surface except for a short lower-surface portion where the puparium is formed; however, the single mine found on E. graminifolia was entirely on the lower surface (Eiseman &amp; Lonsdale 2018). Further rearing will be required to determine whether any observed differences in the mines of these three species are consistent.</p><p>Ophiomyia verni does not readily key in Spencer &amp; Steyskal (1986), and resembles a number of species with a male vibrissal fasciculus on a produced gena with a vibrissal angle of about 60°. It differs from congeners in having a combination of a frayed fasciculus, two short ori, a slightly denser brownish dusting of pruinosity of the notum with a very faint greenish reflection, a relatively pronounced facial bulb with a slight furrow on the dorsal margin that originates on the lunule, an acute angle on the vitta posteriorly where the ocellar triangle meets the orbital plate, eight rows of acrostichal setulae, no setae medially on the mid tibia and a wing length of only 1.6 mm. The surstylus is also relatively small, the mesophallus is quite short, and the characteristic distiphallus is shallow with most of the basal half covered by a partially membranous surface that has the anterior margin sclerotized and raised.</p><p>When contrasting the above diagnosis to the two other Euthamia -mining Ophiomyia, O. euthamiae is the most similar overall and likely a sister-species, externally differing mainly in being larger (wing length 2.0– 2.4 mm). Ophiomyia maura is also slightly larger (wing length 1.8–2.1 mm), and while some specimens are not apparently with a faint metallic shine, it is now apparent that some have this shine, which is variable in color. Both of the other species also have a united, pointed fasciculus, the mid tibial seta is sometimes present, and they have the base of the mesophallus and distiphallus nearly level, and the distiphallus is widest towards the base of the segment (not at the middle) and the ventrodistal surface not darkened. The puparium of the O. verni type is concealed within the tissue of its host (pinned with the specimen), so comparison of this life stage is not possible at the moment.</p></div>	https://treatment.plazi.org/id/038B879BFFED743312C0D9424D6EB55F	Public Domain	No known copyright restrictions apply.

Moench], Sonchus L., [ S. asper (L.) Hill, S. oleraceus L.], Tragopogon pratensis L.</p><p>Larval biology. (Figs. 149–151) The larva forms a linear stem mine, up to 20 cm long or more, whitish when fresh, later turning brown, with black frass typically deposited in two rows of grains and short strips. Distinct primary feeding lines are sometimes evident (observed on Pyrrhopappus). On larger plants, numerous mines may be present on a single stem. M.W. Palmer (in litt.) has opened several of the “scabs” described below and found larvae inside, possibly continuing to feed on the coagulated latex before pupariating.</p><p>Puparium. Formed within the mine, often but not always near the basal end, with the anterior end oriented either up or down; mostly black, with the concealed (ventral) surface paler (pale yellowish to brown or reddish-brown); posterior spiracles arranged in a shallow semi-circle to J-shape, with 7–10 pores. On Lactuca (except for L. muralis), Nabalus, Pilosella, Pyrrhopappus, and Sonchus, a conspicuous gall-like “scab” of stem tissue and dried latex often forms over the puparium. On other hosts, and sometimes on the preceding hosts (especially on peduncles and narrower stems), no “scab” forms and the puparium is plainly visible beneath the stem epidermis, typically bulging out somewhat from the surrounding stem. Rarely, a puparium formed within a “scab” is more or less uniformly dark brown.</p><p>Phenology and voltinism. Multivoltine, with pupae overwintering. Mines with “scabs” have been found as early as mid-May in Texas. In Iowa, mines collected in late June yielded adults in early July, mines collected in late July yielded adults in early August; and mines collected in early September yielded adults the following spring (Eiseman et al. 2021). Collections of mines in North Carolina in late July, and in Vermont in early September, yielded some adults within a few weeks and additional adults the following spring.</p><p>Adult diagnosis. (Figs. 314–321) Wing length 2.2–2.4 mm (♂), 2.6 mm (♀). Length of ultimate section of vein M 4 divided by penultimate section: 0.9–1.0. Eye height divided by gena height: 7.0–8.2. Two ori, two ors; anterior dorcocentral ⅔–⅘ length of posterior; eight rows of acrostichal setulae; mid tibia with 0–1 posteromedial setae; vibrissal fasciculus strongly upcurved, pointed (as in holotype) to tip or variably frayed from apex to base. Frontal vitta usually quite distinctly longitudinally wrinkled, often with desclerotized to broken midline that widens around anterior corner of ocellar triangle; ocellar triangle not much longer than wide and less than half length of frons; orbital plate narrow, not readily differentiated from vitta. Lunule three times wider than high; facial carina distinct, bulb slightly wider than space between antennal bases with only dorsal margin sharply delimited; genal process exceeding length of antenna, narrowed apically, basally forming an approximate 60° angle (at most); clypeus with anteromedial margin produced as a narrow, apically truncated process; parafacial and orbital plate narrowly visible laterally. Setae black; body dark brown with very faint greenish metallic tint; entirely subshining, denser on notum, sometimes appearing velvety on head; calypter margin light to dark brown, hairs dark brown; wing veins whitish brown to brown. Surstylus small, narrow, rounded, slightly to more strongly projecting, with three inner rows of tubercle-like setae; hypandrium with apodeme subquadrate; basiphallus asymmetrical, with left arm reduced and right arm long, reaching distiphallus; distiphallus large, length subequal to basiphallus, ovate with distal half slightly narrower; illustrated specimens show dimension extremes, with shape narrower (Figs. 315, 316; as in holotype; length almost 2.5 times width) with distal margin rounded to relatively broad (length 1.8 times width) with distal margin flatter; membrane arising from distiphallus faintly pigmented for a short distance along two apical margins. Specimens with thicker distiphallus (Figs. 318, 319) always with frayed fasciculus and up to 10 pores on posterior pupal spiracle, those with narrower distiphallus usually with pointed fasciculus and usually 7 pores on spiracle.</p><p>Specimens reared from Lapsana vary slightly but distinctly, but the external and male genitalic morphology are otherwise the same: Vibrissal fasciculus pointed; slightly darker, greenish tint on body absent, but frontal vitta and center of gena with bluish iridescence; vitta not grooved; wing veins dark brown; distiphallus slightly wider than the narrower form described above, which does occur in some “typical” males.</p><p>Distribution. USA: [CT], *IA, [IL], *MA, [ME, MI], NC, [NH], *NY, *OK, *OR, [PA, TX], *VT, *WA (Spencer &amp; Steyskal 1986).</p><p>Comments. This is the species mentioned by Eiseman et al. (2019) in the Comments under Ophiomyia sp. 2, and treated by Eiseman et al. (2021) as O. cf. chondrillae Spencer. All of the known hosts of this fly belong to the tribe Cichorieae . Most other North American Ophiomyia spp. on plants in this tribe are leafminers rather than stem miners. The true O. chondrillae is known only from the holotype (Spencer &amp; Steyskal 1986: Figs. 227–229), reared from a stem mine on Chondrilla juncea L. in Washington state. As discussed by Eiseman &amp; Lonsdale (2018), the record of O. coniceps mining in Sonchus stems is erroneous; in fact the feeding site on this host was not documented; O. coniceps mines in leaf blades and petioles of Antennaria, and if it were to be found in Sonchus stems it should be distinguishable by the whitish to dark brown puparium (dorsally black in O. vockerothi puparia when no “scab” is present). Ophiomyia nabali Eiseman &amp; Lonsdale feeds in petioles and stems of Nabalus albus (L.) Hook.; its puparium is black and is formed just beneath the epidermis as in O. vockerothi (Eiseman et al. 2021) . In the single instance that O. nabali was reared from a stem, the mine was deeper and much less conspicuous than those of O. vockerothi; no “scab” was formed, as usually occurs with O. vockerothi on this host; and based on available photos, the stalks of the anterior spiracles of O. nabali are substantially longer than is typical for O. vockerothi . Ophiomyia congregata mines in the stemlike petioles of Nabalus altissimus (L.) Hook. basal leaves in early spring, but this species has never been observed to mine in stems and has a whitish puparium (Eiseman &amp; Lonsdale 2018). Given the above, we feel it is safe to attribute the mine found in Maine on Scorzoneroides autumnalis to O. vockerothi; this is the only listed host genus not confirmed by rearing. It should be noted that the Holarctic species Phytoliriomyza arctica (Lundbeck), although never reared in North America, is recorded as a stem miner of Cichorieae in Europe. According to Hering (1957), its puparium is likewise formed below the stem epidermis but is brownish-yellow.</p><p>Verifying the identity of the specimens here determined to be Ophiomyia vockerothi has been an ongoing process by the authors, in part due to the superficial similarity of the enlarged distiphallus of this and other species in published illustrations, but also the presence of what is here interpreted as intraspecific variation. The examination of additional reared material and described type specimens has hopefully better delineated the boundaries of this and the other similar species, which will be compared below.</p><p>To begin, Ophiomyia vockerothi is re-diagnosed above, noting slight variation in the shape of male vibrissal fasciculus and in the shape of the distiphallus. The specimens from Lapsana differ most strikingly in not having a greenish tint, and having a blue iridescent frontal vitta and gena.</p><p>Several other putatively related species with an enlarged distiphallus are as follows, but none have the above greenish coloration or the grooved (or split) frontal vitta. Ophiomyia duodecima Spencer (host unknown) has a much larger and diamond-shaped distiphallus and a straighter, pointed fasciculus. Ophiomyia sexta Spencer (host unknown; see Lonsdale (2021: Figs. 386–387)) has three ori, a 70°–80° vibrissal angle and a distiphallus that is smooth on the basal half and widest medially.</p><p>Ophiomyia undecima Spencer (Figs. 322, 323; host unknown) and O. chondrillae (Fig. 324; on Chondrilla) are most similar in phallic morphology, but the distal half of the distiphallus is proportionately narrower and overall with relatively fewer internal spinules, the basiphallus left arm is slightly longer and better sclerotized, there are no mid tibial setae, there are only 6 rows of acrostichal setulae, and the calypter is paler with the hairs dirty yellow (no portion is dark brown), and the eye height is only 6.5 and 4.6 times higher than the gena (respectively).Additionally, the gena is shinier, being almost shining in O. undecima and glossy in O. chondrillae, the latter of which is also nearly shining on the rest of the body. Ophiomyia undecima Spencer further differs in having a wing length of 2.0 mm, the vibrissal angle is about 70–80°, the fasciculus is frayed and there are three ori on the right side. Ophiomyia chondrillae further differs in having a wing length of 2.2 mm and the fasciculus is pointed. The preservation of the genitalia does not allow for determination if the apodeme of the hypandrium is quadrate or pointed.</p><p>Several other distantly-related species with an enlarged distiphallus are Ophiomyia beckeri, O. congregata, O. decima, O. frosti, O. pulicaria, O. pulicarioides Sehgal, and O. quarta Spencer, but these species have a narrower, segmented distiphallus with a distoventral bridge connecting the halves of the basiphallus, there is no produced gena or fasciculus, and there is no greenish coloration.</p></div>	https://treatment.plazi.org/id/038B879BFF93743012C0DCC34AD0B6CB	Public Domain	No known copyright restrictions apply.

Steffen, stem mine with puparium on Penstemon calycosus (iNat 124384306); same but mine in leaf and stem (iNat 124384896).</p><p>Hosts. Plantaginaceae: Penstemon calycosus Small, P. digitalis Nutt. ex Sims.</p><p>Larval biology. The larva forms a long, linear mine. In Wisconsin, the observed mine involved the stem and peduncles. In Illinois, the mines were primarily in these structures but also entered the leaf midribs. The Minnesota mines were in stems as well as in basal leaf blades, midribs, and petioles (BG 2062575).</p><p>Puparium. Whitish (black in some Minnesota examples, but adults did not emerge from these, so it is unknown whether they were parasitized or this is the normal color of overwintering puparia), formed just beneath the plant epidermis, with the anterior spiracles protruding. Puparia have been found in peduncles, stems, and in midribs of basal leaves.</p><p>Phenology and voltinism. At least bivoltine; the Wisconsin specimen emerged in early July from a puparium in a peduncle of the current year’s stem, collected in late June; the Minnesota specimens emerged in late October from puparia collected in late September.</p><p>Distribution. USA: IL, MN, WI.</p><p>Comments. No Ophiomyia has been reported from Penstemon previously. The habit of mining primarily in the stem, with occasional excursions into leaves, is reminiscent of O. mimuli, which is now known from both Phrymaceae and Lamiaceae —families that, like Plantaginaceae, belong to the order Lamiales . However, O. mimuli adults differ from these females reared from Penstemon in having a shallower gena with a sharper angle anteriorly at the vibrissa, the facial bulb is much larger and prominent (not shallow and inconspicuous), and the body is smaller with a more flattened head (not more robust with a higher head).</p></div>	https://treatment.plazi.org/id/038B879BFF90743012C0DC374B05B2DB	Public Domain	No known copyright restrictions apply.

Amaranthaceae: Chenopodium album L., C. quinoa Willd. (Lonsdale 2021; Szczepaniec &amp; Alnajjar 2023).</p><p>Larval biology. (Figs. 152, 153) The young larva forms a long, very narrow, whitish linear mine, without evident frass, on the upper surface of the leaf blade. This eventually enters the petiole, through which the larva mines into the stem. Short stretches of externally visible mining may be present on the stem (just one example was observed), but once in the stem, the larva feeds primarily as a pith borer. When finished feeding, the whitish larvae exit the stem to pupate. Many emerged within a week after their host plants were collected, and they were observed to jump frequently, covering up to a few cm per jump.</p><p>Puparium. Yellow-orange to brown; formed outside the host plant.</p><p>Phenology and voltinism. This species is at least bivoltine. In Massachusetts and in Spain, larvae feeding in mid- to late June emerged as adults in mid-July (Gil-Ortiz et al. 2009). In Ontario, larvae have been collected in mid-September, with adults emerging from overwintered puparia (Lonsdale 2021). We observed adults on foliage of the mined plants in Massachusetts in mid-June; adults have been collected in mid-May (MD), late May (QC), early June (SK), mid-June (MD, MB, ON), late June (MD, ON, QC), early July (MD, AB, NS, QC, SK), mid-July (AB, QC), late July (ON, QC), early August (ON, NS), mid-August (ON), early September (MD), and mid-September (MD) (Boucher 2012; Lonsdale 2021).</p><p>Distribution. USA: CO (Szczepaniec &amp; Alnajjar 2023), *MA, MD, [WI]; Canada: AB, BC, MB, NS, ON, [PE], QC, SK; Europe; China; Mongolia; South Korea; Morocco (Lonsdale 2021; Daief et al. 2025).</p><p>Comments. Gil-Ortiz et al. (2009) were the first to report a rearing record for this species; they reared a single male from Chenopodium vulvaria L. in Spain in 2006, but provided no information about the larval biology. Lonsdale (2021) listed three specimens reared from C. album in Ontario in 1990, along with others collected in quinoa fields in Saskatchewan in 2017, but the label data gave no indication of the larval habits. Szczepaniec &amp; Alnajjar (2023) reported A. karli as a stem-boring pest discovered in Colorado quinoa fields in 2021. They illustrated the larva and puparium, but did not document the oviposition or pupation habits, only observing that “extensive feeding of A. karli larvae destroys the pith and likely disrupts nutrient transport which causes lodging, reduced yield, and loss of the crop due to plant mortality or declining plant health.” They noted exit holes in stems but did not determine whether they were caused by larvae or adults emerging. Thus, the leaf-mining and pupation habits of this species are reported here for the first time. Eiseman (2018) described the leaf mines, collected in Massachusetts in 2014, but failed to determine what caused them, succeeding only in rearing the leafminer Pegomya atlanis Huckett ( Anthomyiidae) from the collected plant material. As described by Ellis (2024), the Palearctic species A. chenopodivora Spencer has identical habits, feeding on both Chenopodium and Amaranthus L., although Ellis states that it normally oviposits in the stem and only occasionally in the leaf.</p></div>	https://treatment.plazi.org/id/038B879BFF97743612C0D82A4AE2B3FA	Public Domain	No known copyright restrictions apply.

Bignoniaceae: Catalpa bignonioides Walter (Frick 1959), C. bungei C.A.Mey. (Frick 1953), [ C. ovata G.Don, C. speciosa Teas]. It is unclear why Frick (1959) listed C. bignonioides and not C. bungei, the host given by Frick (1953) when reporting what is apparently the only rearing record for this species prior to ours. The type was swept from an unspecified catalpa (Malloch 1914), and no other material was known in 1959.</p><p>Leaf mine. A greenish to whitish linear-blotch on the upper leaf surface, with blackish frass forming two rows of grains or short strips in the linear portion, and in scattered grains and small lumps in the blotch.</p><p>Puparium. Brown; formed outside the mine.</p><p>Phenology and voltinism. Scheffer et al. (2007) listed a pupa obtained from a mine collected in Maryland in May; otherwise all observations of mines throughout the range of this species have been in June or later. Our collection of larvae in Michigan in late June yielded four adults in late July (23–33 days later) and four the following spring. No dates were provided in connection with the only previous rearing record (Frick 1953). The holotype was caught in Illinois on 21 June (Malloch 1914). In Ontario, Spencer (1969a) listed specimens caught on 28 July, and Boucher (2012) listed specimens caught on “ 21.ii.1962 ” and “ 28.ii.1964 ”. We have verified that the label data on the last specimen were correctly transcribed, but the February dates are not actual collection dates; these probably represent the dates the specimens were logged in at the Canadian Forest Service office in Sault Ste. Marie. We have recovered the original data from the Forest Insect Disease Survey, which indicate that the collection actually occurred on 16.vii.1963 from a nursery in St. Williams near Turkey Point Provincial Park by J.R. Trinnell. While the original data could not be recovered for the first specimen, the date similarly represents a processing date, with the actual collection event being in the summer of the previous year. An adult was photographed on 27 August in Toronto (iNat 182129693).</p><p>Distribution. USA: [AL, CT, CO, DC, GA, IA], IL (Malloch 1914), [IN, LA, MA (Eiseman &amp; Blyth 2022), MD (Scheffer et al. 2007)], *MI, [MN, MO, NC, NE, NH, NJ, NY], OH (Frick 1953), [OK, PA, TN, VA, VT, WI]; Canada: ON (Spencer 1969a). Boucher (2012) noted that the locality Spencer (1969a) reported as being in Quebec is actually in Ontario.</p><p>Comments. Spencer &amp; Steyskal (1986) noted that as many as five mines of Amauromyza pleuralis had been seen in a single leaf. Although we did not count the number of mines per leaf, our collection of three leaves produced eight adult flies as well as 25 hymenopteran parasitoids ( Figitidae: Zaeucoila robusta (Ashmead); CSE4855, USNM), each emerging from a separate puparium; thus, there were on average 11 mines per leaf.</p></div>	https://treatment.plazi.org/id/038B879BFF96743512C0DB674C1CB2FF	Public Domain	No known copyright restrictions apply.

There is currently no evidence that A. hendeliana occurs in North America, but were it to be discovered here, the records for A. cornigera based only on photographed mines would have to be reevaluated.</p></div>	https://treatment.plazi.org/id/038B879BFF95743412C0D8634A5FB073	Public Domain	No known copyright restrictions apply.

S.F.Blake, S. mollis Nutt., S. occidentalis (R.Br.) Hook., S. orbiculatus Moench, [ S. parishii Rydb. (Spencer 1981)], S. rotundifolius A.Gray., Triosteum aurantiacum E.P.Bicknell, [ T. perfoliatum L.] (Eiseman et al. 2021; Lonsdale 2021). Lonsdale (2021) listed a female collected by Spencer at “Alameda Co., Berkeley, [illegible], 15.v.1977, on Lonicera involucrata ” (Richardson) Banks ex Spreng., but Spencer (1981) evidently changed his mind about the plant identification after the label was made; under Hosts/biology he listed “ Lonicera spp. (not involucrata),” and his listed material from Alameda Co. reads: “Berkeley, ex Symphoricarpos albus, 3 males, 3 females, VII.28–IX.11.48, Lot 13-1 (K.E.F.); Strawberry Canyon, 1 female and leaf-mines on same host, V.15.77 (K.A.S.).”</p><p>Leaf mine. (Figs. 154, 155; Eiseman &amp; Lonsdale 2018: Fig. 100) Linear or linear-blotch; see Eiseman &amp; Lonsdale (2018) and Eiseman et al. (2021). Mines on Lonicera reticulata ( = prolifera) and L. sempervirens are long, gradually widening, and linear throughout, only in small leaves contorting to form a secondary blotch.

As noted by Eiseman et al. (2021), this species is multivoltine, with collected larvae often emerging as adults within a few weeks, but larvae collected in spring sometimes undergo a year-long pupal diapause. In one instance, larvae collected in late May in North Carolina emerged as adults in the first half of October.</p><p>Distribution.

(Sasakawa 1961), hybrid weeping willows, and possibly other ornamental Salix spp. Also see Comments.</p><p>Leaf mine. (Fig. 156) A narrow, whitish, linear mine with frass in black grains that are mostly widely spaced; on the lower or occasionally the upper leaf surface. Two digitate blotches (iNat 54226798) were found in association with typical mines of this species.</p><p>Puparium. Brown to dark brown; formed within the mine. Also see Guglya (2021, including Figs. 72–74).</p><p>Phenology and voltinism. This species is reported to be bivoltine in Europe (Ellis 2024), and it appears to be so in the USA as well. Mines with puparia appear by mid-June, with empty puparia being found in late July; puparia collected in November yielded adults the following spring.</p><p>Distribution. * USA: [CA, NJ], NY; Europe; Japan (Sasakawa 1961).</p><p>Comments. Five Salicaceae-feeding Aulagromyza species are known, all of them occurring in Europe (Spencer 1976, 1990), and this is the third to be found in North America. The Populus feeder A. populicola (Walker) suddenly appeared in large numbers on P. deltoides W.Bartram ex Marshall in Ottawa in 1956 (Frick 1959), and it was reared from the same host in Oklahoma in 2016 and 2017 (Eiseman &amp; Lonsdale 2018). In Europe and Canada it has been reported to make greenish upper-surface blotch mines, pupating externally (Frick 1959; Spencer 1969a; Ellis 2024), but the mines in Oklahoma were whitish and distinctly linear at first, widening to 5–6 mm, with the puparia formed internally. Eiseman &amp; Blyth (2022) attributed to this species broadly linear mines found on the lower surface of P. grandidentata Michx. leaves in Massachusetts, but they were identical to mines of A. tremulae (Hering) (not known to occur in North America), and could conceivably have been made by that species. The Salix feeder A. tridentata (Loew) was reared in Delaware in 1960, collected in Maryland in 1977, and reared in Colorado in 2003 (Scheffer et al. 2007; Lonsdale 2021). It makes a yellowish primary blotch mine, almost always on the lower leaf surface, and normally pupates externally but sometimes within the mine (Ellis 2024). The final species, A. fulvicornis (Hendel) (not known to occur in North America), forms narrow linear mines on Salix spp., switching from the lower to the upper leaf surface, and pupating externally (Ellis 2024).</p><p>Aulagromyza populi (Fig. 43) is found exclusively on Populus in Europe (Ellis 2024), but Sasakawa (1961) also reared it from Salix babylonica in Japan (with up to 22 larvae found per leaf); this record was ignored by Spencer (1976, 1990) and Benavent-Corai et al. (2005). In the USA, A. populi has been found exclusively on ornamental Salix spp., mostly S. babylonica or hybrids thereof. This suggests it is a recent introduction from Asia. Leaf mines were first documented in San Mateo, California in 2019, with observations in San Jose beginning in 2020. Mines were documented in New York City beginning in 2020, with nearby observations on Long Island in 2022 and in New Jersey in 2023. A parasitized mine found on weeping willow in southeastern Pennsylvania in 2023 (iNat 169498093) is rather blotchy and might represent A. tridentata, but the fact that it is whitish and formed on the upper leaf surface is suggestive of A. populi, as is the host.</p></div>	https://treatment.plazi.org/id/038B879BFF9A743A12C0DEE64A8FB0EE	Public Domain	No known copyright restrictions apply.

First flagellomere small, rounded; apex slightly tapered with slightly longer hairs along margin. Orbital plate and parafacial slightly projecting (viewed laterally), forming a slight angle where they meet; continuing as a distinct cheek under eye. Notum subshining.</p><p>Chaetotaxy: Two ori (three on left side), two ors; setae decreasing slightly in length anteriorly; all setae missing on right side. Postvertical and ocellar setae subequal to ors. Two strong dorsocentrals with second seta about ¾–⅘ as long; smaller third dorsocentral about ⅓–½ as long as second, with only one setula separating those setae. Six irregular rows of acrostichal setulae to level of first dorsocentral. Mid tibia with one to two strong posteromedial setae.</p><p>Coloration: Setae black; setulae brown. Head mostly yellow; antenna, ocellar spot and narrow region behind it, clypeus, palpus and back of head (except for small yellow spot on either side of ocellar tubercle) dark brown; posterolateral corner of frons dark brown to base of outer vertical seta, fading to brown to base of inner vertical and anteriorly along eye margin (but not reaching level of ors). Notum dark brown with lateral light yellow stripe; scutum margin lateral to scutellum narrowly yellow. Pleuron dark brown with posterodorsal margin of anepisternum light yellow. Wing veins brownish yellow. Calypter white. Legs dark brown, slightly paler than thorax; trochanters yellowish apically; apex of fore femur yellow for length equal to width of femur apex; fore tibia slightly paler with base yellow; fore tarsus paler brown. Abdomen dark brown.</p><p>Genitalia: (Figs. 325–330) Epandrium well-developed with typical cluster of tubercle-like setae posteroventrally. Surstylus narrowing apically, inner-distal surface with setae, small postero-apical ridge with three tubercle-like setae. Cercus well-developed. Postgonite and hypandrium typical of genus. Phallophorus subcylindrical with narrow band forming ventral surface. Basiphallus dorsum short and lightly sclerotized, with sides expanding and becoming more heavily sclerotized anteriorly. Hypophallus mostly membranous with sides lightly clouded; with single membranous flagellum anteromedially. Paraphallus absent. Ejaculatory duct minutely wrinkled in annulations. Mesophallus rounded at ends, about twice as long as high (highest past midpoint), and with slight lateral constriction medially; with small, narrow ventrobasal process that extends onto base of hypophallus; small dark sclerite present ventrally between mesophallus and distiphallus. Distiphallus with short, dark bowl-like basal structure that is wider than mesophallus but about as high, with margin ringed by small pointed projections; ventral surface of bowl fused to base of one pair of dark medial tubules that are almost as long as mesophallus, slightly angled dorsally and depigmented in a short subapical ring. Ejaculatory apodeme with pale blade and long, wide stem; sperm pump with one pair of small sclerotized patches; ejaculatory duct widened and pigmented apically.</p><p>Comments. This species was discussed by Eiseman &amp; Lonsdale (2018) as Calycomyza sp. 1, comprising a series of females. These females are included here as paratypes. While originally thought to have a partial resemblance to C. platyptera (Thomson), they differ from that species and resemble the above holotype male as follows: size slightly larger (wing length of C. platyptera 1.5–1.8 mm (♂), 1.6–2.2 mm (♀)), orbital plate yellow (not with dark stripe to base of posterior ors), scutum narrowly yellow adjoining scutellum (not entirely dark); puparium yellowish-brown (not brown) and formed outside the mine; host plant Eupatorium altissimum ( C. platyptera is not known from any Eupatorieae aside from Mikania Willd.). Two additional females from this host have been collected in Indiana and match the external morphology of these Kansas females; these are also included here as paratypes.</p><p>Although four Calycomyza species have now been reared from Eupatorium s. str. in North America (the others being C. eupatoriphaga Eiseman &amp; Lonsdale, C. flavinotum (Frick), and C. serotini sp. nov.), this is so far the only one to be reared from E. altissimum . The distinct yellowish color of C. altissimi mines, which appears to be the result of some palisade mesophyll just below the upper epidermis being left uneaten, has not been observed in Calycomyza mines on any other Eupatorium, which are invariably whitish.</p><p>While it is not possible to differentiate Calycomyza altissimi from most other Calycomyza with a pale orbital plate externally, its phallus is highly unusual and diagnostic. The basiphallus is nearly triangular and the mesophallus is rounded and bulging with a slight lateral constriction. The distiphallus is particularly noteworthy, having a dark, apically spinulose bowl-like base and one pair of long, dark apical tubules that have a clear subapical ring. The long distiphallus tubules are superficially similar to C. hyptidis Spencer (Spencer &amp; Steyskal 1986: Figs. 933, 934), but its phallic structure is otherwise quite different. The most similar phallus is likely seen in C. avira Eiseman &amp; Lonsdale, which has a somewhat similar mesophallus (although wider than high), no paraphallus and a similar basal bowl on the distiphallus, but the bowl surrounds one pair of wider, shorter, clear fringed tubules (Eiseman &amp; Lonsdale 2018: Figs. 266, 267). This species is also known from Asteraceae, but its hosts are in the tribe Coreopsideae rather than Eupatorieae (see below).</p></div>	https://treatment.plazi.org/id/038B879BFF99743812C0DEE649C3B4BF	Public Domain	No known copyright restrictions apply.

Asteraceae: Baccharis halimifolia L.</p><p>Leaf mine. (Figs. 160, 161) Whitish, upper-surface, usually along the leaf margin; initially narrow and linear, expanding to an elongate blotch. A diffuse brown line runs through the linear portion and continues more broadly through the blotch, but no distinct frass particles are deposited until the larva is ready to pupate.</p><p>Puparium. (Fig. 47) Light brown; attached by its posterior end to a large, blackish lump of frass deposited on the floor of the mine.</p><p>Phenology and voltinism. This species appears to be multivoltine. Mines appear in North Carolina by early May, and mines containing larvae or puparia have been collected in mid-May, late May, early June, mid-June, and mid-July, with adults emerging 1–16 days later.</p><p>Distribution. USA: [AL, FL, GA], NC, [SC].</p><p>Adult description. (Fig. 45) Wing length approximately 1.5–1.6 mm (♂), 1.7–1.9 mm (♀). Length of ultimate section of vein M 4 divided by penultimate section: 2.7–2.9. Eye height divided by gena height: 3.7–6.9. First flagellomere small, rounded, but area around arista base more broadly flattened; distal margin with slightly longer hairs. Frons sloping downwards, orbital plate becoming more prominent (seen laterally) anterior to fronto-orbital setae, meeting parafacial at an angle; parafacial narrow but clearly visible laterally, continuing as narrow cheek under eye. Thorax faintly subshining, with pruinosity slightly denser on scutum, more so towards center anterior to first dorsocentral; pruinosity grayish, but sometimes appearing bluish depending on light angle observed.</p><p>Chaetotaxy: Fronto-orbitals relatively short, slightly decreasing in length anteriorly; two ori (sometimes absent from one side); two ors (anterior seta sometimes strongly inclinate, resembling ori). Ocellar seta slightly larger than ors; postvertical slightly larger than ocellar. Two strong dorsocentral setae with second seta nearly as long as first; third seta much thinner and almost half length of second seta; setula in front of third dorsocentral sometimes slightly larger, resembling fourth seta. Mid tibia without posteromedial setae.</p><p>Coloration: Setae black. Head light yellow with ocellar spot, back of head, antenna and palpus dark brown; clypeus dark brown with midpoint slightly paler; posterolateral corner of frons dark brown to base of inner vertical seta; base of posterior ors surrounded by minute spot that may be difficult to see. Thorax mostly dark brown; notum with lateral light yellow stripe; dorsal margin of anepisternum light yellow (narrowest anterior to midpoint) or only with posterodorsal margin narrowly yellow; dorsal margin of meron light yellow. Wing veins light yellow. Calypter light yellow. Legs dark brown, with apex of fore femur and base of fore tibia very narrowly yellow, sometimes appearing almost entirely dark. Abdomen dark brown.</p><p>Genitalia: (Figs. 331–335) Epandrium with cluster of concealed tubercle-like setae anteroventrally that is only partially visible externally (usually exposed in congeners). Surstylus with row of stout inner-marginal setae and shorter row of three tubercle-like setae on shallow ventral ridge. Cercus well-developed. Phallophorus not much higher than long, venter shorter than dorsum. Basiphallus weakly sclerotized dorsally; plate-like structures only visible anterodorsally as small patch that widens anteriorly, and lateromedially as one pair of narrow bands. Hypophallus with subrectangular sclerotized plate on anteromedial surface that is notched on distal margin and with a subbasal pit; short, membranous flagellate structure emerging from center of plate. Paraphalli well-developed, bases connected to each other through dark transverse band that is also medially connected to narrow extension arising from ventrobasal margin of mesophallus; paraphallus as long as mesophallus, base dark and ventrally curved, and apex much paler and expanded. Mesophallus narrow, dark, subcylindrical, gradually swelling to rounded base (less pronounced in lateral view); very small rounded sclerite suspended below space dividing mesophallus and distiphallus. Distiphallus (seen laterally) with very short, narrow stem, and broader, rounded distal section that is composed of a dark base and one pair of rounded paler plates that mostly conceal one pair of dark, cylindrical tubules. Ejaculatory apodeme well-developed with margin of blade clear and stem thick; apical sclerotized patch on ejaculatory duct connected to ventral sclerotized patch on sperm pump.</p><p>Comments. Mines of Calycomyza humeralis (von Roser), which is recorded from Baccharis douglasii DC. in California (Frick 1956), can be rather similar to those of C. baccharidis, but so far there is no record of C. humeralis using Baccharis in eastern North America, where we have only found it on Erigeron L. (Eiseman &amp; Lonsdale 2018).</p><p>Adults of Calycomyza baccharidis can be difficult to differentiate from congeners using external and male genitalic morphology, such as the more commonly encountered, and quite superficially similar C. platyptera, but C. baccharidis has a subrectangular plate-like hypophallus. Calycomyza platyptera also feeds on Baccharis, but its leaf mine is quite different, being digitate and usually centered on the midrib, not elongate and following the leaf margin. A similar hypophallus is seen in several Nearctic species such as C. cynoglossi (Frick) (Figs. 342–346), C. majuscula (Frick) (Figs. 354–356), C. menthae Spencer (Figs. 360–362), C. orientalis Spencer (Fig. 359) and C. novascotiensis Spencer (Figs. 363–368), but these are larger species with darker calypter hairs, a longer distiphallus and a narrower paraphallus.</p><p>Most similar to Calycomyza baccharidis overall, however, are the adults of the similarly small-bodied species C. humeralis and C. solidaginis (Kaltenbach), which also have a more sloping frons, slightly projecting parafacial and orbital plate, similar leaf mine morphology, and internal pupation. As with these two species, the first flagellomere is sometimes pointed, but in smaller specimens the area around the arista is somewhat more flattened than in the simple circular state seen in most congeners. The structure of the phallus and ejaculatory apodeme are also highly similar, although the phallus of the other two species has a smaller, narrower paraphallus, the basiphallus is more sclerotized, and the hypophallus is divided into two J-shaped sclerites. Like C. solidaginis, the face of the new species is yellow, but C. solidaginis is not known from Baccharis, and the adult can be diagnosed by being darker laterally behind the transverse suture, having a restricted paler brown region or a very small yellow mark (scutum not entirely yellow laterally, sometimes with the supra-alar region faintly brownish).</p></div>	https://treatment.plazi.org/id/038B879BFF9F743E12C0DEE64C27B247	Public Domain	No known copyright restrictions apply.

Nutt.</p><p>Leaf mine. (Fig. 162) Whitish, on the upper leaf surface. Both of the photographed examples (one of which is illustrated here) began as a linear mine that originated near the base of the leaf, encountered the angle between the midrib and a lateral vein, and then reversed direction, later abruptly expanding to a blotch.

Eye height divided by gena height: 5.6. First flagellomere small, rounded. Ocellar triangle rounded, not much larger than tubercle. Cheek narrow. Notum appears subshining (whitish residue partially obscuring surface).</p><p>Chaetotaxy: Two ori, slightly thinner and shorter than ors, with anterior ori ⅗ length of posterior; two ors. Ocellar seta subequal to posterior ori; postvertical seta subequal to posterior ors. Three strong dorsocentral setae; second seta about ⅘ length of first; third about half length of second, and only separated from that seta by one setula. Eight rows of acrostichal setulae to level of first dorsocentral. Katepisternum with series of several short but well-developed setae along posteroventral margin and posterodorsal margin. Mid tibia with two posteromedial setae.</p><p>Coloration: Setae dark brown. Head mostly light yellow; antenna (excluding yellow arista base), ocellar spot, posterolateral corner of frons to base of inner vertical seta, back of head and palpus dark brown; clypeus dark brown with midpoint faded yellow.

Metanotum dark brown with posterodorsal corner of anatergite brown and katatergite paler brown. Wing veins brown. Calypter margin yellow, hairs brown. Legs mostly dark brown; apex of fore femur yellow for length subequal to apex width; base of fore tibia yellow on basal ⅖, becoming darker distally; tarsi yellowish. Abdomen dark brown.</p><p>Genitalia: (Figs. 336–341) Epandrium with dense cluster of tubercle-like setae posteroventrally. Surstylus inner distal margin with straight setae anteriorly and tubercle-like setae posteriorly. Cercus well-developed. Phallophorus subcylindrical, slightly constricted medially (viewed laterally). Basiphallus not reaching phallophorus, composed of two dorsolateral sclerites that are slightly wider and darker before base of paraphallus, where the halves are weakly connected by narrow, transverse sclerotized bridge; apices weakly continuing laterally long sides of membranous hypophallus. Paraphalli weakly sclerotized, widening and slightly overlapping apically. Mesophallus dark, subcylindrical, narrowest at base, slightly swollen apically, about two times longer than wide; base rounded and extended ventrally as flat bifurcated process; minute, rounded, floating sclerite present ventrally between mesophallus and distiphallus. Distiphallus extremely dark, about as long as mesophallus but higher and wider; downturned at narrowed apex. Ejaculatory apodeme with marginally pale blade and wide stem; apex of minutely annulated ejaculatory duct pigmented, partially confluent with irregular sclerotizations on proximal half of sperm pump.</p><p>Comments. This is the first record of any agromyzid being reared from Brickellia . We have seen linear-blotch mines of unknown Calycomyza species on B. betonicifolia A.Gray in Arizona, on B. californica (Torr. &amp; A.Gray) A.Gray in Arizona and New Mexico, on B. grandiflora in Colorado, on B. pringlei A.Gray in Arizona, and on an undetermined Brickellia in California. We have also seen linear mines of unknown Liriomyza spp. on Brickellia spp. in all of these states.</p><p>Calycomyza brickelliae belongs to the C. artemisiae group, which is most readily diagnosed by the exceptionally dark, downturned distiphallus, which is globose to elongate, but always slightly asymmetrical. Species in this group cannot be reliably diagnosed externally, requiring male dissection. Calycomyza brickelliae differs in having a particularly large, stout distiphallus that is about as long as the apically widening mesophallus, and apically narrows to a broad, rounded point. The paraphalli are also pale, with the apices expanded and overlapping, and the bases free from the bifurcated extension of the mesophallus.</p></div>	https://treatment.plazi.org/id/038B879BFF9E743D12C0DBBB4AAAB16E	Public Domain	No known copyright restrictions apply.

I.M.Johnst., [ Lithospermum caroliniense (J.F.Gmel.) MacMill., L. helleri (Small) J.I.Cohen], * L. latifolium Michx., [ L. molle (Michx.) Muhl., L. officinale L., L. parviflorum Weakley, Witsell &amp; D.Estes], * Myosotis laxa Lehm. Frick (1956) reported the host as “ Cynoglossum ”; Frick (1959) listed both “ Cynoglossum spp. ” and “ Cynoglossum virginianum ” (the latter now placed in Andersonglossum) as hosts for this fly, but there is no specific record from Cynoglossum L. s. str. (i.e., C. officinale L.), so this host genus requires confirmation.</p><p>Leaf mine. (Fig. 163) A whitish linear-blotch on the upper leaf surface. The mine begins with a long, narrow serpentine portion with frass in beaded strips or closely spaced grains along the sides, then expands to a blotch with frass in scattered irregular particles or liquidy arcs.</p><p>Puparium. Reddish-brown; formed outside the mine.</p><p>Phenology and voltinism. This species is evidently multivoltine. Larvae have been collected in late April (AR), early June (IL), late June (IL), and mid-July (ON), with adults emerging 14–22 days later. All specimens of the type series, reared in Indiana, were labeled with dates in September, perhaps referring to adult emergence times, but this is unclear (Frick 1956) .</p><p>Distribution. USA: *AR, [IA], *IL, IN (Frick 1956), [MI, MN, ND, NE, PA, TX, VA, WI]; * Canada: ON. Frick’s (1956) type series included caught specimens from across Canada (including ON), and in the eastern USA south to Kansas and Virginia (including MI, PA, and WI), but Spencer (1969a) found the Canadian specimens he examined to be misidentified. Spencer &amp; Steyskal (1986) apparently were likewise unable to verify any of Frick’s distribution records, listing only Indiana and “not Quebec.”</p><p>Comments. This is the only Calycomyza species known to feed on Boraginaceae . The adult can be characterized by a number of features, but some material may not be diagnosable using existing keys due to variation in external coloration—the male reared from Myosotis has an orbit that is not dark to the anterior fronto-orbital, but only to the base of the anterior ors, with only minute spots present at the base of the ori. Similar coloration is seen in the Arkansas female reared from Andersonglossum, which is here included on the basis of its host family. Aside from this, the Myosotis -reared male has a dark-haired calypter, a dark, subshining notum, and a small discal cell (length of ultimate section of vein M 4 divided by penultimate section 2.0–2.3).As usual, however, the male genitalia (Figs. 342–346) are most diagnostic: the hypophallus is fused to the basiphallus and subquadrate in shape with a deep distomedial emargination; the paraphallus is flared apically; the mesophallus is very narrow and slightly downcurved; the distiphallus is upturned and subquadrate in profile with a very small, narrow basal stem. Other species with a plate-like hypophallus have the structure narrower and rarely as apically notched, and the distiphallus differs in shape.</p></div>	https://treatment.plazi.org/id/038B879BFF9D743C12C0D8D34925B073	Public Domain	No known copyright restrictions apply.

The species name is a patronym for Dr. Rodrigo Diaz, one of collectors of the only known specimen.</p><p>Host. Asteraceae: Chromolaena odorata (L.) R.M.King &amp; H.Rob.</p><p>Leaf mine. Unknown; likely a whitish blotch or linear-blotch as in other Eupatorieae-feeding Calycomyza spp ..</p><p>Puparium. Unknown.</p><p>Phenology and voltinism. The only known specimen was reared in early November.</p><p>Distribution. USA: FL.</p><p>Adult description. Wing length approximately 1.7 mm (♂). Female unknown. Length of ultimate section of vein M 4 divided by penultimate section: 2.2. Eye height divided by gena height: 7.0. First flagellomere small, rounded; distal margin with slightly longer hairs. Ocellar triangle slightly larger than tubercle, rounded. Cheek narrow. Notum subshining. Aristae missing; left fore leg missing past trochanter; right fore leg embedded in glue; right hind leg missing.</p><p>Chaetotaxy: Two ori with anterior seta slightly shorter; two ors (missing). Postvertical and ocellar setae missing. Two dorsocentral setae (only left first seta remaining). Acrostichal setulae in about six rows that reduce posteriorly to level of first dorsocentral. Mid tibia with two posteromedial setae.</p><p>Coloration: Setae black, setulae brown. Head mostly light yellow; ocellar spot, back of head, palpus and posterolateral corner of frons to level of inner vertical dark brown; first flagellomere dark brown, and scape and pedicel light brown; posterior margin of eye very narrowly brown to level just anterior to posterior ors; clypeus brown with middle slightly paler. Thorax dark brown with whitish-yellow markings; most of postpronotum, notopleuron and small anterolateral spot behind transverse suture pale; posterodorsal corner of anepisternum very narrowly pale; dorsum of meron yellow. Wing veins light brown. Calypter margin yellow, hairs yellow with slight brownish tint. Legs mostly dark brown; trochanters brownish-yellow; color of fore femur apex not discernable in specimen (likely yellow apically as adjoining tibia is yellow); base of fore tibia yellow; tarsi yellowish. Abdomen dark brown.</p><p>Genitalia: (Figs. 347–350) Epandrium small, with tubercle-like setae on posteroventral surface that are relatively few (apparently no more than 12 on each side) and positioned more along the inner surface. Surstylus subquadrate with three tubercle-like setae on posteroventral corner. Cercus well-developed. Phallophorus subcylindrical with ventral surface shorter. Basiphallus made of two long, narrow, floating dorsolateral sclerites. Hypophallus with one pair of sclerites that are darker and slightly longer than basiphallus, with margins irregular but better-defined; nearly straight when viewed laterally, incurved when viewed anteriorly. Paraphallus dark, very narrow and sharply curved ventrally at midpoint; paraphalli connected at base by ventrobasal extension of mesophallus, which is subrectangular and wider than long. Ejaculatory duct minutely annulated. Mesophallus (seen laterally) very straight with venter more thickly sclerotized, about four times longer than high, slightly swollen near base; seen ventrally, slightly wider with basal ⅗ strongly swollen, nearly spherical. Distiphallus almost half length of mesophallus, apically membranous, composed of one pair of dark, narrow, curved plates that have an abrupt lateral swelling past midpoint; plates do not appear to conceal any inner structures. Ejaculatory apodeme with broad stem and comparatively narrow, pale blade; apex of ejaculatory duct and adjoining sperm pump lightly sclerotized.</p><p>Comments. This species, known from the holotype alone, represents one of the specimens listed as C. eupatorivora Spencer in Diaz et al. (2015). The remaining four specimens are true C. eupatorivora, and are listed below under that species; the genitalia of one of the males in that series are illustrated here for comparison. Both species mine leaves of Chromolaena odorata, and it is unknown how their mines differ. The mine of C. eupatorivora was described by Eiseman &amp; Lonsdale (2018).</p><p>Calycomyza diazi differs from many congeners in having the lateral scutal stripe end just past the transverse suture, leaving the postsutural scutum almost entirely dark, and in having the pedicel and scape light brown (not dark brown). This combination of characters provides a superficial resemblance to C. lantanae (Frick), to which it will key in Spencer &amp; Steyskal (1986), but in that species the scape and pedicel are yellow and the genitalia are quite dissimilar.</p><p>Examination of the genitalia of Calycomyza diazi provides more reliable diagnosis, with a quadrate surstylus, fewer tubercles on the surstylus and epandrium, and a unique phallus. Additionally, the hypophallus sclerites are dark, flat and incurved, the paraphallus is bent medially and very narrow, the mesophallus in profile appears flat, and viewed ventrally, the basal section is swollen so as to almost appear spherical. The distiphallus is also very narrow and accentuates the straight profile of the mesophallus.</p></div>	https://treatment.plazi.org/id/038B879BFF83742212C0DEE64B6EB67F	Public Domain	No known copyright restrictions apply.

R.M.King &amp; H.Rob., Arctium lappa L., A. minus (Hill) Bernh., Eupatorium perfoliatum L., Eutrochium *fistulosum (Barratt) E.E.Lamont, E. maculatum (L.) E.E.Lamont, E. purpureum (L.) E.E.Lamont (Eiseman &amp; Lonsdale 2018). Spencer (1990, p. 251, Table 56) listed Calycomyza flavinotum among the species that feed on Carduus L., but this is not supported by any prior literature, and in the text accompanying this table (p. 253) he only stated that C. flavinotum “forms large blotch mines on Arctium in eastern U.S.A., but probably feeds primarily on Eupatorium .” We therefore consider this record erroneous.</p><p>Leaf mine. (Eiseman &amp; Lonsdale 2018: Figs. 107–108) One mine on Eupatorium perfoliatum was observed to begin as an irregular linear track that gradually expanded to a blotch, but all other mines from which we have reared this species have begun as an irregularly lobed blotch (in one case preceded by a short linear track) with frass deposited in a central mass. Ultimately the mine expands to a large, whitish blotch with frass in numerous fine grains and small lumps; in some examples on Eutrochium, primary and secondary feeding lines form a distinct herringbone pattern. Mines of several larvae frequently coalesce to form a single blotch. Frost (1924, as Agromyza allecta Melander) stated that mines on Arctium lappa are always made on the lower leaf surface, but we have only observed this species to make upper-surface mines, including on Arctium spp.</p><p>Puparium. Reddish-brown or rarely yellowish-brown; formed outside the mine.</p><p>Phenology and voltinism. This species is multivoltine. Larvae have been collected in mid-June (MI), late June (IA, MI, MN), early July (ON), mid-July (MA), late August (NC), and mid-October (NC), with adults emerging 19–35 days later; occupied mines have also been found in early August (NB). Larvae collected in mid-August (CT) produced an adult the following spring; larvae collected in early September (MA) yielded one adult 33 days later and others the following spring (Eiseman &amp; Lonsdale 2018; Lonsdale 2021).</p><p>Distribution. USA: *CT, *IA, IL, [KY], MA, MD, ME, *MI, MN, *NC, [NE, NH], NY, [OH], PA, VA, [VT], WI; Canada: [MB, NB], ON, [QC] (Lonsdale 2021). Lonsdale (2021) reported this species from California, based on a single specimen: “Mpls. Orium, Minnehaha, [illegible], 3.viii.1980, mine Eupatorium rugosum, 29.vi.1980 (1♂, USNM).” This host plant (= Ageratina altissima) does not occur in California, and the collection site was actually Minnehaha Creek in Minneapolis, Minnesota—the specimen was reared by Spencer and is listed in Spencer &amp; Steyskal (1986).</p><p>Comments. This species likely shares multiple hosts in the tribe Eupatorieae with C. eupatoriphaga, although so far Ageratina altissima is the only plant species from which males of both flies have been reared (we have found only C. eupatoriphaga on Ageratina, but Spencer once reared C. flavinotum from this host in Minnesota as noted above). The genus Eupatorium is used by both species, as well as by C. serotini sp. nov.; at present there is no indication that C. eupatoriphaga uses Eutrochium, or that C. flavinotum uses Conoclinium . Early mines of C. eupatoriphaga tend to be more regular in outline with a brownish longitudinal frass streak, rather than more or less digitate with a brown central spot as in C. flavinotum; otherwise the mines of these two species are extremely similar. To err on the side of caution, we have ignored the numerous purported photographic records for both species, with the exception of leaf mines on Arctium, which appear safe to attribute to C. flavinotum (along with photographed adults with the diagnostic pair of broad yellow posterolateral spots on the scutum).</p></div>	https://treatment.plazi.org/id/038B879BFF81742012C0DF1F4C58B6CB	Public Domain	No known copyright restrictions apply.

Asteraceae: [ Bidens cernua L.], B. frondosa L., Helianthus L., Rudbeckia L., [ R. laciniata L.] (Spencer &amp; Steyskal 1986).</p><p>Leaf mine. (Fig. 164) Frost (1924), who conflated Calycomyza frickiana with C. flavinotum under the name Agromyza allecta Melander (Frick 1956), described the mine only as “large, whitish” and on the upper leaf surface. Spencer &amp; Steyskal (1986) described it as a “greenish blotch mine” and a “large blotch mine.” The three mines we observed on Bidens cernua were pale green, upper-surface blotches, each containing a single larva. Each began with a distinct linear portion with dark frass deposited in closely spaced grains along the sides; this linear portion was partially obliterated in one mine (which began near the base of a leaf) and completely obliterated in the others (which began near the leaf apex), but in each case it was still traceable as a brown line within the blotch. Frass in the blotch was otherwise diffuse.</p><p>Puparium. Formed outside the mine. According to Spencer &amp; Steyskal (1986), the puparium of C. frickiana is brown, with three bulbs on each of the posterior spiracles. Our tentatively identified female emerged from a reddish-brown puparium.</p><p>Phenology and voltinism. Calycomyza frickiana is evidently multivoltine. Reared specimens are labeled with (emergence?) dates of late July (PA), early August (PA), late August (MD), and late October (NY); caught specimens have dates of late May (IN, VA), early June (SD), mid-June (IL), and September (VA) (Spencer &amp; Steyskal 1986; Lonsdale 2021). Our tentatively identified female was collected as a larva in early September and emerged as an adult 26 days later.</p><p>Distribution. USA: IL, IN, [MA], MD (Lonsdale 2021), [MN], NY, [OH (Frick 1956)] PA, SD, VA (Spencer &amp; Steyskal 1986). The MN record is based on leaf mines observed on Rudbeckia laciniata; the OH record (as Phytobia (Calycomyza) allecta (Melander)) is based on a puparium from Rudbeckia sp.

The mines of Calycomyza frickiana on Bidens probably cannot be distinguished from those of C. avira . Adults of C. avira differ in having a dark stripe from the back of the frons to the base of the last fronto-orbital, which is lacking in this female. However, any female Calycomyza with a head lacking this stripe and with dark calypter hairs cannot be identified confidently.</p></div>	https://treatment.plazi.org/id/038B879BFF80742012C0DC374ACFB183	Public Domain	No known copyright restrictions apply.

The small, brownish blotch mine on Lycopus asper Greene reported from Alberta by Spencer (1969a) also seems likely to be the work of Calycomyza menthae . Hansson (1987) listed specimens of Chrysocharis crassiscapus ( Eulophidae) reared in Alberta from Calycomyza on Agastache foeniculum (Pursh) Kuntze, Galeopsis tetrahit L., and Stachys palustris L., which may all represent C. menthae . Rearings from the latter two hosts in particular would be desirable, since the only Calycomyza -like mines we have seen on Galeopsis and Stachys appear actually to be the work of Nemorimyza posticata (Meigen) (rearing has confirmed both genera as hosts for this fly; see below).</p><p>Leaf mine. (Figs. 165, 166) On most hosts, the mine begins as a narrow brown line, expanding to a messy, brownish blotch with clean, whitish margins here and there; frass is in scattered grains and small lumps. Feeding lines like those of Nemorimyza posticata are visible in some examples. On Scutellaria, the mine begins as a gradually widening, serpentine track. On Blephilia, the mine is whitish and begins with a long, narrow linear portion with frass in black grains or strips along the sides, later expanding to a blotch that may obliterate the linear portion. Frass in the blotch may be in scattered black particles or almost nonexistent (Eiseman &amp; Lonsdale 2018; Eiseman et al. 2019).</p><p>Puparium. Variously yellow, yellowish-brown, orange-brown, pale reddish-brown, brown, or dark brown; formed outside the mine.</p><p>Phenology and voltinism. This species is multivoltine. Larvae have been collected in late April (OK), late May (MA, NC), mid-June (MI, NC), early July (NC, OH, ON), mid-July (MA, IL, NC, ON), late July (NC, OR), early August (MA, OH), mid-August (MA), and mid-September (NC), with adults emerging 9–31 days later. Larvae collected in late August (NY, VT) and late September (MA) have overwintered as pupae, with adults emerging the following spring (Spencer 1969a; Eiseman &amp; Lonsdale 2018).</p><p>Distribution. USA: [AL, CA, CT, DC, FL, GA, IA], *IL, [IN, KY, LA], MA, [MD, ME], *MI, [MN, MO], NC, [NE, NH, NJ, NM], *NY, *OH, OK, [OR, PA, TN, TX, VA], VT, [WI]; Canada: AB, [BC, MB, NB, NS], ON (Eiseman &amp; Lonsdale 2018).</p><p>Comments. A female reared from Blephilia hirsuta was discussed by Eiseman &amp; Lonsdale (2018) as Calycomyza sp. 4, and a male reared from Scutellaria integrifolia was misidentified by Eiseman et al. (2019) as C. novascotiensis Spencer (see discussion under C. novascotiensis below). With these now assigned to C. menthae, the only other Lamiaceae-feeding Calycomyza species known from the USA or Canada are C. hyptidis and C. salviae, sp. nov. Calycomyza hyptidis is a Neotropical species whose range extends into Florida (with leaf mines recently found in southeastern Georgia: iNat 256753539). It makes a distinctly different leaf mine, consisting of a star-shaped blotch with a mass of black frass accumulated in the center (Spencer &amp; Stegmaier 1973). Calycomyza salviae is only known from California, on cultivated Salvia spp. that are not native to California. Its mine is not obviously different from that of C. menthae, which has not been confirmed to occur in California, and is only tentatively recorded there based on mines found on Monardella (Spencer 1981; Spencer &amp; Steyskal 1986) and Ocimum (this paper), neither of which are confirmed hosts for C. menthae . The only other Calycomyza mines we have seen on Salvia have been in Texas (where C. menthae is recorded based on mines found on Monarda spp.), and we have tentatively assigned these to C. salviae .</p></div>	https://treatment.plazi.org/id/038B879BFF87742512C0DDDF4905B4F7	Public Domain	No known copyright restrictions apply.

(Eiseman &amp; Lonsdale 2018: Fig. 115) Whitish, upper-surface; initially linear, expanding to a blotch that typically overruns the linear portion. On young, tender leaves, the blotch may be full-depth. Through the linear portion is a broad, diffuse, brown band containing irregular, blackish frass particles; these particles are sparsely scattered in the blotch.</p><p>Puparium. Yellow to brown; formed outside the mine. The female from New York pupated within the mine.</p><p>Phenology and voltinism. This species is multivoltine, with larvae of the first generation appearing well before any other Calycomyza species are active in New England. Larvae have been collected in late March (MA), late May (NC), early June (NC), late June (NY), early July (MI), mid-July (NC), and early August (VT), with adults emerging 14–31 days later in each case. Occupied mines have been found as late as 5 September in Vermont; of the two larvae collected, one wandered for days after exiting its mine, and then died without pupating; the other pupated, but an opiine braconid emerged from its puparium the following spring. The appearance of larvae in early spring suggests the possibility that eggs or young larvae may overwinter in basal leaves, but this requires further investigation.</p><p>Distribution. USA: [CA, CO, CT], MA, [ME], MI, [MN, MT], *NC, [NY, OR, PA], *VT, [WA, WI]; Canada: [AB, BC, NB], NS, [ON, PE] (Spencer 1969a). The tentative Alberta record is based on Hansson’s (1987) listing of a specimen of Chrysocharis crassiscapus ( Eulophidae) reared from a Calycomyza species on “ Hieracium canadense ” [= H. umbellatum].</p><p>Comments. The identities, limits, and host species of Calycomyza novascotiensis and its relatives are here refined based on the examination of additional material and the examination of type specimens. This lineage, most readily identified by a large, plate-like hypophallus, includes a number of species, but only three that have been reared or reported on by the present authors will be examined in detail here: C. novascotiensis, C. michiganensis Steyskal, and C. menthae .</p><p>Comparison of type material of Calycomyza novascotiensis (Figs. 363–367) and C. michiganensis (Fig. 368) has revealed the two to be synonymous, and consequently reidentifies the specimens treated as C. michiganensis in Eiseman &amp; Lonsdale (2018); diagnoses of species provided in that study were based on misidentifications, which are corrected below. As such, the junior C. michiganensis syn. nov. is here included as a synonym of C. novascotiensis . The most characteristic feature of C. novascotiensis is the fossa visible in the distiphallus when viewed laterally (Fig. 367, 368), and while the holotype slide of C. michiganensis is preserved with the venter visible (Fig. 365), the dimensions of the phallus otherwise match all examined C. novascotiensis, including the holotype of that species, which is rediagnosed as follows: wing length 2.1–2.5 mm (♂), 2.2–2.5 mm (♀); length of ultimate section of vein M 4 divided by penultimate section: 2.2–2.6; eye height divided by gena height: 5.4–6.4; usually 2 ori and 2 ors, but sometimes 1 or 3 ori on one side; orbital plate brown at least to posterior ors and with fainter strip reaching anterior ors, but sometimes fainter brown to anterior ori; stripe on orbital plate narrower between setae, and if reaching one or more ori, then stripe either continuous or with isolated spots at base of ori; face brown on dorsal ½–⅔; notum slightly shining; two strong dorsocentrals, second nearly as long as first, sometimes with smaller third dorsocentral anteriorly (half length of second seta); legs dark brown with base of fore femur narrowly light yellow; mid femur with 1–3 posteromedial setae; the surstylus has a broad outer face with numerous tubercle-like setae, except at the pointed anterior corner where there are long and short setae; the basiphallus is about as long as the mesophallus, which has a slight ventral curve, the base and apex are both modestly swollen (best viewed ventrally), the mesophallus is about 6⅔ times its width at the middle, and the ventral margin is produced as a shallow plate; the hypophallus is long and ovate with the distal margin rounded; the paraphalli are bent at right angles basally and weakly connected, they are long and narrow with the apices wider, pointed and slightly asymmetrical; the distiphallus (seen laterally) is subconical and long, being slightly more than half the length of the mesophallus, and it is mostly dark excluding a clear medial fossa; the distiphallus (seen ventrally) has a strong oblique medial constriction, and it is only slightly wider apically, where there is a pronounced lip around the distal margin.</p><p>In comparison, Calycomyza menthae (Figs. 360–362) is rediagnosed as follows: wing length 1.9–2.2 mm (♂), 1.9–2.5 mm (♀); length of ultimate section of vein M 4 divided by penultimate section: 2.2–2.5; eye height divided by gena height: 3.9–6.3; all specimens observed with 2 ors and 2 ori; orbital plate brown at least to base of posterior ors, but usually also fainter to base of anterior ors (less commonly faintly brownish or slightly orange to ori, or with spots at base of ori); face brown on dorsal ⅔ or entirely brown; notum slightly more pruinose, grayer; third dorsocentral always present; apex of fore femur and base of fore tibia light yellow; mid femur with 2–3 posteromedial setae; surstylus smaller, with fewer setae and tubercles; plate-like hypophallus always with end shallowly to more deeply emarginate; broad membranous lobe of paraphallus only with sclerotized, apically narrowing bar along venter; mesophallus about as long as basiphallus, but shape straighter and slightly narrower with apex not swollen; distiphallus (best viewed in lateral view) with abrupt narrow stem at base and small, rounder distal chamber that lacks a medial fossa. Characters of the puparium appear to be too subtle to differentiate between the two species, and vary according to state of preservation.</p><p>Based on the above diagnoses, the North Carolina record of Calycomyza novascotiensis from Scutellaria integrifolia L. ( Lamiaceae) in Eiseman et al. (2019) is here reinterpreted as a misidentification of C. menthae (see above). Calycomyza novascotiensis is here accepted as being a miner solely on Asteraceae, reared from the plant genera Hieracium and Pilosella, and C. menthae is an exclusive miner of Lamiaceae .</p></div>	https://treatment.plazi.org/id/038B879BFF85742B12C0D82B4C3CB03B	Public Domain	No known copyright restrictions apply.

A female matching the description of Calycomyza platyptera was reared from Euthamia graminifolia (L.) Nutt., but the leaf mine was atypical for this species (Eiseman &amp; Lonsdale 2018). All of Frick’s (1956) host records (as Calycomyza jucunda (van der Wulp)) that were considered questionable by Eiseman &amp; Lonsdale (2018) are now accepted, based either on examination of specimens reared from these hosts (Lonsdale 2021; this paper) or on photographed mines listed above. Frick’s (1959) records from Solidago spp. are also accepted since mines have been observed on several species in this genus (Stegmaier 1967; this paper). We are hesitant to accept Symphyotrichum simmondsii (Small) G.L.Nesom (as Aster simmondsii) as a host based only on Stegmaier’s (1967) observation of leaf mines, since the mines of the Symphyotrichum specialist C. promissa (Frick) are essentially identical if not opened to inspect the puparium. With the exception of Heliopsis (leaf mine recently observed in Wisconsin), we still have seen nothing to support the questionable records from Spencer &amp; Steyskal (1986) and Spencer (1990) summarized by Eiseman &amp; Lonsdale (2018).</p><p>Leaf mine. (Eiseman &amp; Lonsdale 2018: Fig. 116) A whitish, digitate blotch, often centered on the midrib, conspicuously deforming young leaves. On most hosts the blotch is on the upper surface, but on Echinacea, Helianthus, Mikania, and Silphium it is frequently on the lower surface. The blotch may be preceded by a short to rather long linear portion, which may be partly on the lower surface (observed on Iva). Frass is concentrated in a dark mass at the center of the blotch.</p><p>Puparium. Brown, attached to a flattened lump of frass at the center of the mine. The upper epidermis is often torn such that the puparium is exposed (observed, e.g., on Ambrosia, Helianthus, and Ratibida).</p><p>Phenology and voltinism. This species is multivoltine. Mines containing larvae or puparia have been collected in early April (FL), mid-April (NC, OK), late April (FL), early May (NC, OK), mid-May (FL, OK), late May (OK), early June (NC), mid-June (IA), late June (IA, WI), early July (CO, KS, WI), mid-July (CA, IA, MA, NC), late July (MA, NC), mid-August (NC), late August (MA), early September (MA), mid-October (NC), and late December (FL), with adults emerging 1–29 days later (Stegmaier 1967; Eiseman &amp; Lonsdale 2018; Eiseman &amp; Blyth 2022).</p><p>Distribution.

The specific epithet refers to the genus of the host plant, Salvia L.</p><p>Hosts. Lamiaceae: Salvia microphylla Kunth, S. uliginosa Benth. Mines possibly representing this species have been found in California on S. canariensis L., S. chiapensis Fernald, S. guaranitica A.St.-Hil. ex Benth., and plants tentatively identified as S. involucrata Cav. All of these are cultivated plants that are not native to California, and only S. microphylla, S. chiapensis, and S. involucrata are native to North America. Similar mines have also been found in Texas on cultivated S. elegans Vahl and on native S. ballotiflora Benth., S. coccinea Buc’hoz ex Etl., and S. farinacea Benth.</p><p>Leaf mine. Whitish, on the upper leaf surface; initially linear, with blackish frass in an almost continuous, beaded line; expanding to a blotch with the frass in a diffuse central patch and scattered irregular particles (iNat 191028105, 252111383).</p><p>Puparium. Yellowish-brown; formed outside the mine.</p><p>Phenology and voltinism. Larvae have been collected in late September and mid-November, with adults emerging in mid-October and early December. An adult not examined by us was collected as a larva in early June and emerged in mid-June.</p><p>Distribution. USA: CA and possibly TX.</p><p>Adult description. Wing length 2.4 mm (♂), 2.5 mm (♀). Length of ultimate section of vein M 4 divided by penultimate section: 2.4. Eye height divided by gena height: 7.0. First flagellomere small, rounded. Ocellar triangle round, slightly larger than tubercle. Notum subshining.</p><p>Chaetotaxy: Two ors, two ori; setae decreasing in length anteriorly. Postvertical and ocellar setae subequal to anterior ors, but thinner. Two strong dorsocentral setae; female with one very small seta in front of second dorsocentral that is about twice length of setulae. Six rows of acrostichal setulae. Mid tibia with two posteromedial setae.</p><p>Coloration: Setae black. Head mostly light yellow; dorsal half of face brown; antenna, back of head and palpus dark brownish-black; clypeus dark excluding narrow yellow line on dorsomedial margin; dark stripe along vertex meeting dark brown ocellar tubercle medially, and dark region in posterior corner of frons laterally, with region encompassing vertical setae and posterior ors, and extending as fainter narrow stripe to base of anterior ors. Thorax mostly dark brown to black; posterior corner of postpronotum, notopleuron and narrow lateral postsutural stripe light yellow; scutum with one pair of minute faded yellowish spots adjoining corners of scutellum; dorsal margin of anepisternum and anepimeron narrowly light yellow posteromedially and anteriorly (respectively). Calypter margin and hairs dark brown, Legs dark brown to black with apex of fore femur and base of fore tibia very narrowly light yellow. Abdomen dark brownish-black; female ovipositor with light yellow spot on single dorsobasal swelling.</p><p>Genitalia: (Figs. 369–372) Epandrium separate from surstylus, with dense cluster of tubercle-like setae posteroventrally. Surstylus rounded, about as high as long, inner surface setulose with setae in posteroventral region tubercle-like.Cercus well-developed.Phallophorus subcylindrical with venter shortened.Basiphallus well-developed, Y-shaped with narrow arms extending to enclose hypophallus laterally. Hypophallus with wide, dark basomedial sclerite that bears long flagellum that is sclerotized along wider dorsobasal surface; basal sclerite appearing weakly attached to one pair of flat, faint ventromedial bands, the left one of which has prominent long, pointed process. Paraphalli fused medially, forming ventrobasal pocket that supports mesophallus; laterally extending as two large, flat lobes (ventral lobe pointed and dorsal lobe with narrow band-like arch). Mesophallus dark, not much longer than wide, with subapically constricted neck and broader swollen base; with dark, flat, floating medial sclerite between it and distiphallus ventrally. Distiphallus very dark, essentially black; subcylindrical with height about half length, about as long as section of phallus between mesophallus and phallophorus. Ejaculatory apodeme large and well-sclerotized, with thick stem and only slightly widened blade; sperm pump with dark offset sclerite nearer to base of duct.</p><p>Comments. With Calycomyza menthae now confirmed from eight Lamiaceae genera (see above), we cannot exclude the possibility that some of the mines found on Salvia represent that species rather than C. salviae . To our knowledge, the only previous record of a Calycomyza species being reared from Salvia is that of Spencer (1973) from Venezuela (on “ Salvia aff. longimarginata,” a synonym of S. angulata Benth.). Spencer stated that the single reared male was indistinguishable from C. hyptidis, but he noted that based on the leaf mines it appeared to represent a distinct species: the larva forms a slightly irregular, pale green blotch, with distinct frass scattered throughout the mine, rather than the typical star-shaped blotch with frass in a central mass; “more material will be necessary before this species can be satisfactorily described.”</p><p>While not confidentally diagnosable using external characters, the adult of Calycomyza salviae can be partially characterized by a mostly dark postpronotum and a narrow lateral light yellow postsutural stripe, a minute pair of faint yellowish spots adjoining the scutellum, a faint line on the orbital plate extending to the anterior ors, the dorsal half of the face is brown, and the fore leg is very narrowly light yellow at the femoral/tibial joint. The phallus is most diagnostic, with heavily modified paraphalli that are bilobed laterally and fused to form a pocket ventrally to partially enclose the dark, basally swollen mesophallus. The hypophallus is divided into three unusual sclerites, including a dark basomedial structure with a mostly clear flagellum, and two paler asymmetrical ventral bands. The distiphallus is also distinctly large, stout, subcylindrical and black.</p></div>	https://treatment.plazi.org/id/038B879BFF8F742D12C0D8B54BEEB4F7	Public Domain	No known copyright restrictions apply.

Calyomyza eupatoriphaga has also been reared from Eupatorium serotinum, and it is unknown whether there is any consistent difference in the leaf mines of the two species, although fresh mines of C. eupatoriphaga appear whitish, in contrast with the dirty appearance of the small portion of a C. serotini mine that was photographed at the time of collection.</p><p>While externally indistinguishable from most congeners with a pale orbital plate and dark calypter hairs, the genitalia immediately identify Calycomyza serotini . The shape of the mesophallus and the medial sclerite are unusual in the genus, but the circular plate on the hypophallus with a sclerotized flagellum, and the structure of the flat, curled distiphallus are unique.</p></div>	https://treatment.plazi.org/id/038B879BFF8D742C12C0DA6B4A73B32F	Public Domain	No known copyright restrictions apply.

Whitish with diffuse brown discoloration, which is darker in the linear portion. Frass is in scattered grains and small, irregular lumps. Concentric feeding lines are evident in the blotch.

Apart from one female from Massachusetts that emerged in mid-July, without a pupal diapause, all other data indicate this species is univoltine, with larvae present in June, normally overwintering as pupae and emerging as adults the following spring (Spencer 1969a; Eiseman &amp; Lonsdale 2018).</p><p>Distribution. * USA: MA; Canada: AB, MB (Spencer 1969a).</p><p>Comments. This species was discussed by Eiseman &amp; Lonsdale (2018) as Calycomyza sp. 3 . The newly reported collection of mines also produced a female of an inquiline leafminer, Minettia?americanella Shewell ( Lauxaniidae), which likewise overwintered as a pupa and emerged as an adult the following spring (Eiseman 2021). The mines on Nabalus are rather common on Mt. Wachusett in central Massachusetts, but we seen no evidence of this fly elsewhere in New England in over a decade of intensive leafminer studies. A mine possibly made by C. sonchi has been found on Sonchus asper (L.) Hill in Pennsylvania (iNat 221856199).</p><p>Calycomyza sonchi is similar to C. majuscula in having a slightly projecting, shinier and largely black orbital plate that continues anteriorly past the anterior ori onto the dorsum of the parafacial as a light brownish stripe. The two species differ subtly, with C. sonchi having two or three ori (only two in C. majuscula), a paler calypter margin with ochreous hairs (reportedly brownish to black in C. majuscula), and asteraceous hosts in the tribe Cichorieae ( Sonchus and Taraxacum). Calycomyza majuscula instead has hosts in the tribe Senecioneae, including Senecio; Petasites is tentatively included, as it was recorded as a host in Alaska without supporting data in Spencer (1981), and Spencer did not record Alaska as part of that species’ distribution in later works. As the specimens recorded here are from Cichorieae ( Nabalus), the calypter margin and hairs are ochreous, and the specimens have 3 ori, they are here treated as C. sonchi .</p><p>The limits of Calycomyza sonchi (Figs. 357, 358) and C. majuscula (Figs. 354–356) should be reapproached at a later date as there appear to be problems in the descriptions provided for these species by Frick and Spencer. Examination of Frick’s paratypes of C. majuscula at the CNC reveals the specimens to have three ori on at least one side, the calypter is pale, and a dissected male has genitalia essentially identical to those of C. sonchi . Examining the types of C. sonchi, it appears as though the paratypes from Churchill, Manitoba are not conspecific with the holotype (from Alberta), with the pigment on the orbital plate paler and restricted to the posterior region, and the genitalia of the dissected male appear distinct (despite being preserved on an oblique angle) with an apically pointed fan-shaped paraphallus most similar to that of C. orientalis (Fig. 359). As such, the original descriptions of the two species are incomplete in part, as are their comparisons in Spencer (1969a), requiring future examination of species limits.</p></div>	https://treatment.plazi.org/id/038B879BFFB3741212C0DABF4D0AB42B	Public Domain	No known copyright restrictions apply.

Willd.</p><p>Leaf mine. (Figs. 170, 171) Two whitish leaf mines were photographed in association with this rearing. One is a small blotch, containing a live larva, formed away from the leaf margin, with dark frass scattered centrally. The other begins with a distinct linear portion, with frass in beaded strips, and ends in a blotch at the leaf margin that appears to contain a dead larva. The single preserved mine begins with a contorted linear portion, then develops into a blotch measuring 24 mm by 12 mm. Viewing this mine in transmitted light reveals dark frass that is centrally deposited in relatively dense, fine particles in the early portion of the blotch, with larger lumps scattered through the remainder.</p><p>Puparium. Not observed, but apparently formed outside the mine as in related species.</p><p>Phenology and voltinism. The only known North American specimens were collected as larvae in mid-June and emerged as adults 20 days later.</p><p>Distribution. * USA: NC; Colombia; Venezuela (Spencer 1973, 1984).</p><p>Comments. The North Carolina specimens examined here closely resemble the Neotropical material described by Spencer (1973) (reared from Stevia elatior Kunth ( Asteraceae)), with minor differences in the male genitalia (Figs. 379–384) likely attributable to intraspecific variation. The small ventral process on the distiphallus in Spencer’s illustration likely matches the base of the unique pair of structures seen on the left side of the phallus observed here, which are very thin and filamentous with an abruptly widened and spherical apex. Other diagnostic features include a yellow orbit with a faint brownish stripe around the vertical setae that may reach the posterior ors, the characteristic shape of the distiphallus, the relatively wide, stout mesophallus with a medial constriction, the H-shaped basiphallus fused to the large U-shaped hypophallus that also bears a flat medial plate from which a short flagellum emerges, and the basomedially confluent fan-shaped paraphalli with sharp distal corners.</p><p>In addition to Mikania and Stevia, C. steviae has been reared in Colombia from “ Gnaphalium sp. ” (Spencer 1984). Spencer (1990), and consequently Benavent-Corai et al. (2005), omitted the latter record for unknown reasons. Benavent-Corai et al. (2005) listed Piqueria as a host of C. steviae, but this was based only on Spencer’s (1990) record of mines found in Costa Rica on P. trinervia Cav. that “probably represent C. steviae .”</p></div>	https://treatment.plazi.org/id/038B879BFFB2741112C0D8634C90B42A	Public Domain	No known copyright restrictions apply.

Caution should be used in identifying this species based only on leaf mines, now that Nemorimyza posticata has been reared from Verbena stricta (see below). Mines of N. posticata are similar in shape, and they are best distinguished by the presence of distinct feeding lines, which may only be evident in transmitted light. Mines of Calycomyza verbenae sometimes begin with a more prolonged initial narrow portion than occurs in N. posticata mines, and fresh mines of C. verbenae are often whitish, making the frass particles much more distinctly visible than in N. posticata mines; however, C. verbenae mines darken quickly with age, and some are suffused with brown even while still occupied.</p></div>	https://treatment.plazi.org/id/038B879BFFB1741012C0DD1749D8B4BF	Public Domain	No known copyright restrictions apply.

(Fig. 174) Up to five larvae feed together, forming a long, yellowish mine (Spencer 1969a).</p><p>Puparium. (Fig. 49) Pale yellowish-brown to brownish-orange, with a blackish central spot on the ventral surface of each segment, these joining to form a continuous longitudinal band; larvae typically pupate side by side, oriented perpendicularly to the leaf venation (Spencer 1969a).</p><p>Phenology and voltinism. In North Carolina, mines containing larvae have been found as early as late May, and a mine collected in late June produced an adult within a month. Mines collected in early July in Ontario, and in early August in Massachusetts, yielded adults 1–13 days later (Spencer 1969a). In Vermont, mines containing larvae and puparia in late August yielded one adult by mid-September and one the following spring.</p><p>Distribution. * USA: [CT], MA, [ME, MI], *NC, [NY], VT; Canada: [BC, NB], ON, [QC] (Spencer 1969a).</p><p>Comments. This species is newly confirmed from the United States (reported from Massachusetts by Eiseman &amp; Blyth (2022) based only on mines with parasitized puparia), with the Massachusetts record representing the female identified as “ Cerodontha (Butomomyza) sp. 1” in Eiseman &amp; Lonsdale (2018). The female of this species is unusual in that existing genus keys will identify it as Butomomyza, having a lunule that is higher than wide, pointed dorsally, light brown and velvety in texture. Additionally, the prescutellar acrostichal setae are as long as those seen in “typical” Butomomyza such as C. (B.) angulata, from which it is almost indistinguishable externally aside from the leg pigment being darker with almost no yellow on the mid and hind legs, the first flagellomere is more broadly rounded with the distal margin more extensively covered with slightly longer hairs (not slightly tapered with a smaller dorsal patch of longer hairs), and the gena is higher, with the eye being only 4.6–8.4 times as high (not 10.6–18.6).</p><p>Leaf mines of Cerodontha scirpivora are common in New England on various Scirpus spp., but adults have been difficult to rear due to an extremely high parasitism rate. Collections most commonly yield adults of opiine braconids, in particular a distinctive reddish species; we have also occasionally reared entedonine eulophids, including Chrysocharis polita (Howard) (CSE2106, CSE2134; NHMUK).</p></div>	https://treatment.plazi.org/id/038B879BFFB5741412C0DD914BB4B32F	Public Domain	No known copyright restrictions apply.

Poaceae: [ Agrostis stolonifera L.], * Cinna latifolia (Trevir. ex Göpp.) Griseb., [ Dactylis glomerata L.], Ehrharta erecta Lam., Elymus repens (L.) Gould, Hordeum murinum L., Poa L. (Frick 1959). Frick (1959, p. 382) stated that the only reared North American specimens he had seen were from Ehrharta erecta, Elymus repens, and H. murinum, so his records of Echinochloa crus-galli (L.) P.Beauv. and Lolium multiflorum Lam. (Frick 1959, p. 438) were evidently drawn from European literature, and E. crus-galli was not a North American record as stated by Spencer &amp; Steyskal (1986), who also incorrectly stated that Frick (1959) had listed D. glomerata as a host for this fly (in fact, Cerodontha dorsalis was the only species he associated with this plant). Spencer &amp; Steyskal’s (1986) own record from D. glomerata was based only on “leaf mines with puparia.” Poa is a new host record for North America, but C. muscina is recorded from P. nemoralis in Europe (Ellis 2024).</p><p>Leaf mine. (Figs. 175, 176) The mine was described by Spencer (1969a) as “uniformly widening... with frass in greenish strips or small lumps; Spencer (1981) and Spencer &amp; Steyskal (1986) described it only as a long, lower surface mine. According to Ellis (2024), the solitary larva forms a broad, lower-surface corridor, somewhat irregular in depth, that mostly descends from the leaf tip, with frass in irregular, green-black granules that are mostly along the sides. Both mines we have seen were largely full-depth and were formed at the leaf apex, occupying the full width of the blade. Backlit photos of the Wisconsin mine reveal that the egg was inserted near the leaf margin well below the leaf apex (as with the example in Guglya (2021, Fig. 104)); the mine was initially narrowly linear with frass in short black strips, and it widened gradually as it followed the leaf margin to the apex, then reversed direction and widened dramatically, with frass in correspondingly larger strips.</p><p>Puparium. (Fig. 50) Shining, iridescent black; formed near the basal end of the mine, with the pointed tips of the posterior spiracles projecting dorsally through the leaf epidermis. Spencer (1981) and Spencer &amp; Steyskal (1986) stated that pupation is internal, while Spencer (1969a) indicated pupation may be either in the mine or external, and according to Ellis (2024) pupation is “generally” within the mine. Also see Guglya (2021, including Figs. 105–106).</p><p>Phenology and voltinism. Puparia collected in late June (WI) and mid-July (PE) yielded adults within a few weeks. Mines collected in Alberta in early August yielded adults the following spring (Sehgal 1971)</p><p>Distribution.

The mine has been variously described as a “serpentine-blotch” (Frick 1959), “irregular blotch” (Spencer 1969a), “initial upper surface linear mine, which later develops into an irregular blotch” (Spencer &amp; Stegmaier 1973), and “short upper surface mine” (Spencer 1981). The leaf photographed in association with the new rearing shows (in addition to numerous host-feeding punctures on the upper surface) linear mines on both leaf surfaces, and the only mine that is clearly occupied switches from the upper to the lower surface (iNat 61616038). Another leaf photographed at the same site a week earlier (iNat 60887579) shows two adjacent mines that likewise have both upper- and lower-surface portions (again associated with numerous host-feeding punctures on the upper surface). The other photographed mines listed above, whose identities were not confirmed by rearing, similarly switched between the upper and lower leaf surfaces. They were mostly linear, sometimes contorted to form secondary blotches, with blackish frass mostly in discrete grains and irregular particles, occasionally in beaded or squiggly strips.</p><p>Puparium. Pale yellow to yellowish-brown; formed outside the mine (Spencer &amp; Stegmaier 1973; Spencer 1981).

In California, this species has been reared in late June, early July (Spencer 1981), and mid-October; the new specimen emerged as an adult 9–10 days after it was collected as a larva. In Florida, larvae have been collected in mid-September (9 days after collection) and mid-October (3 days after collection, apparently as a puparium) (Spencer &amp; Stegmaier 1973). In the northeastern USA, from which no Haplopeodes specimens are known, an empty mine has been found in late July (New York City), and larvae have been found in early to mid-September (MA, PA) and mid-October (NH); puparia from the October collection overwintered and parasitoids emerged from them the following spring ( Braconidae: Opiinae; Eulophidae: Entedonini).</p><p>Distribution.

Phallophorus narrowing and open ventrally; dorsal portion narrowed anteriorly. Basiphallus a single subquadrate sclerite that partially wraps around shaft laterally, is weakly sclerotized distally, and with several short well-sclerotized basal wrinkles that are longer laterally. Distiphallus not differentiated from thickened ejaculatory duct, tapering at apex; portion exposed past basiphallus slightly longer than portion of duct concealed by basiphallus. Ejaculatory apodeme large and well-sclerotized, as long and about as wide as ejaculatory duct / distiphallus past phallophorus; sperm pump semispherical but shallower, with base of apodeme sunken within it.</p><p>Comments: Haplopeodes vittatus is the seventh Haplopeodes species to be reared from Solanum . Haplopeodes kefi Steyskal, which has likewise been reared from S. triquetrum in Texas, as well as from S. umbelliferum Eschsch. in California, was said by Steyskal (1980) to form a highly irregular upper-surface blotch mine that is usually less than 2 cm long; Spencer &amp; Steyskal (1986) described it as a short linear mine, and neither publication mentioned the mode of pupation. The mine of H. eurhabdus Steyskal, reared from S. elaeagnifolium Cav. in Argentina, has not been described (Steyskal 1980). The remaining four species were all described from Brazil. Haplopeodes bullati (Spencer) forms a linear-blotch mine on S. bullatum Vell., with frass in two conspicuous lines in the linear portion and in large, irregular lumps scattered centrally in the blotch, which may obliterate the linear portion; pupation is external (Spencer 1963). Haplopeodes lopesi (de Oliveira &amp; da Silva) forms an inconspicuous lower-surface linear mine on S. argenteum Dunal, with frass in alternating rows; the mode of pupation was not recorded (de Oliveira &amp; da Silva 1954). Haplopeodes verbascifolii (Spencer) forms an inconspicuous, dark green, linear mine on a plant identified as S. verbascifolium L. (a synonym of S. donianum Walp., which does not occur in Brazil according to POWO (2025)), pupating internally at the end of the mine (Spencer 1963). The mine of H. vogti Steyskal on S. erianthum D.Don (also not recorded from Brazil by POWO (2025)) is initially linear, expanding to an elongate upper-surface blotch along the leaf margin; 4– 10 larvae feed together in a single mine, depositing frass in scattered particles and pupating internally (Esposito 1991).</p><p>Haplopeodes vittatus can be readily diagnosed by being the only member of the genus with a vittate scutum. Similar species, such as H. minutus, have most of the scutum gray to the posterior margin adjoining the scutellum.</p></div>	https://treatment.plazi.org/id/038B879BFFB9741812C0DCA74963B2DB	Public Domain	No known copyright restrictions apply.

Abdomen dark brown with tergites narrowly light yellow laterally.</p><p>Genitalia: (Figs. 390–393) Epandrium with one small posteroventral spine; articulating with surstylus. Surstylus with two well-developed subapical spines. Phallophorus chair-shaped. Basiphallus broadly sclerotized along left lateral and dorsoapical surfaces; left distolateral margin extended as broad, clear lobe. Paraphallus narrow, rodshaped, slightly upcurved. Hypophallus narrow, broader at base, and with several long apical hairs. Mesophallus fused to distiphallus, with two paired bands on distiphallus and dorsal and dorsolateral regions of mesophallus darker, contrasting remainder of segments that are largely desclerotized, especially shallow, swollen, chamberlike distiphallus; viewed ventrally, both segments smooth and rounded, mesophallus half width of distiphallus and strongly narrowed at their point of fusion; viewed laterally, mesophallus with raised ventral carina that projects basally, and pigment very dark along dorsal and basal surfaces, as well as on dark distolateral extension that supports base of strongly upturned distiphallus. Ejaculatory apodeme dark and well-developed, with blade narrower and darker approaching stem; base narrow; sperm pump broadly sclerotized ventrally, with dark patch produced as broad extensions laterally, and as dark surface along venter and sides of duct at base.</p><p>Comments. Using the key to Euphorbia -mining species in Eiseman et al. (2021), the new species will key to Liriomyza euphorbiella Eiseman &amp; Lonsdale, which is presently known from Oklahoma on E. cyathophora Murray. Both it and the new species are closely related in a lineage that specializes on that host genus, which in turn shows strong affinities to a number of specialists on Asclepias L., as well as to L. conclavis Lonsdale, which has been reared from both Asclepias and Euphorbia (see below). The new species differs from L. euphorbiella in having minor to extensive pale brown markings on the orbital plate, and while the genitalia are highly similar, the mesophallus and distiphallus of the new species is strongly constricted at their point of fusion (seen ventrally), and the segments have a characteristic pattern of dark and clear structures that are readily identifiable.</p><p>The undeveloped specimen cannot be properly diagnosed, and is only tentatively identified based on its association with the host plant.</p></div>	https://treatment.plazi.org/id/038B879BFFBF741E12C0DB67499CB16E	Public Domain	No known copyright restrictions apply.

Eye height divided by gena height: 4.3–4.8. First flagellomere small, rounded. Notum shining.</p><p>Chaetotaxy: Two ori (anterior seta ⅘ length of posterior), two ors. Four dorsocentral setae, decreasing in length anteriorly (fourth seta approximately ⅓ length of first). Acrostichal setulae in six rows; conspicuous setula-free gap along dorsocentral row.

Surstylus narrow with two apical spines. Phallophorus chair-shaped. Basiphallus sclerotized along much of left lateral surface and on distal half of dorsum; left distal margin thicker and narrowly fused to left paraphallus. Paraphallus narrow, rod-like. Hypophallus narrow, not haired. Mesophallus about as long as distiphallus but slightly narrower; with shallow ventral carina with medial fossa; lateral and dorsal surfaces thicker. Distiphallus slightly angled upwards, with narrower ventral stem fused to mesophallus, and with sclerotized ring surrounding apical opening; distal section cup-like, with dorsal surface longer, covering dorsum of stem-like basal section, and with minute bumps on inner surface; one pair of short membranous tubules emerging from apical opening. Ejaculatory apodeme well-developed, with narrow sclerotized line along distal margin of apically pale blade; sperm pump with broad transverse sclerotized section confluent with sclerotized apical section of ejaculatory duct.</p><p>Comments. We hope that future rearings will better document the appearance of the leaf mines on both leaf surfaces and clarify how consistently the mines of this species differ from those of Liriomyza conclavis, which was found feeding on Asclepias curassavica at the same site where L. calasclepiadis was reared from this host (see below).</p><p>Liriomyza calasclepiadis is a relatively dark species that appears most closely allied to two other similar Asclepias feeders. Liriomyza asclepiadis Spencer is a northeastern species confirmed from Quebec and Massachusetts west to Ontario and Kansas, reared from A. exaltata L., A. incarnata L., A. syriaca L., and A. viridis Walter (Eiseman &amp; Lonsdale 2018) . The new species will key to L. asclepiadis in Lonsdale (2017). Liriomyza subasclepiadis Spencer has been reared from A. speciosa Torr. in Washington state (material not available for this study).</p><p>Liriomya asclepiadis can be differentiated using numerous small features: calypter hairs brown; scutum subshining; lateral margin of orbital plate unpigmented; anepisternum yellow with broad, oblique stripe; surstylus spines smaller; basiphallus broader and not fused to paraphallus; mesophallus narrower and abruptly desclerotized distoventrally and dorsobasally (likely causing apical section of phallus to be additionally upturned at this point); basal stem of distiphallus darker and slightly broader, and apical cup more strongly angled upwards, shallower, clearer and bulging laterally, and shorter and smoother dorsally (Lonsdale 2017: Figs. 217–219). Liriomyza subasclepiadis is apparently identical to L. asclepiadis externally (Spencer &amp; Steyskal 1986), but there are minor differences in the male genitalia, including a narrower apical chamber of the distiphallus, and a darker, shorter and narrower mesophallus that resembles a basal extension of the distiphallus stem (Spencer &amp; Steyskal 1986: Figs. 796, 797).</p><p>Also on Asclepias is Liriomyza peleensis Spencer, but this is a darker species with a more slender distiphallus/ mesophallus that is more extensively fused (Lonsdale 2017: Figs. 285–287).</p></div>	https://treatment.plazi.org/id/038B879BFFBC740312C0DDFA4B80B2FF	Public Domain	No known copyright restrictions apply.

On Asclepias, the mines appear to be linear throughout, although highly contorted; they are largely interparenchymal, appearing greenish with reddish discoloration, with occasional portions more visible on the upper or lower surface (these being whitish). The frass, when visible, is in black strips and more or less closely spaced grains (iNat 115299016). The single photographed mine on Euphorbia was also contorted and linear, with frass in black strips, but it was entirely on the upper surface, where it appeared uniformly whitish (iNat 114101137).</p><p>Puparium. Formed outside the mine; straw-colored when empty.</p><p>Phenology and voltinism. The single previously known specimen was collected as an adult in late March (Lonsdale 2011). Larvae have been collected in mid-April and late April, with reared adults emerging about three weeks later.</p><p>Distribution. USA: CA (Alameda, San Bernardino, and San Diego Cos.).</p><p>Comments. The rearing of Liriomyza conclavis from Asclepias is not surprising since Lonsdale (2011) noted the similarity of its phallus to those of the Asclepias feeders L. asclepiadis Spencer and L. subasclepiadis Spencer. The mine of L. subasclepiadis, known only from Washington, is also interparenchymal and at least partly linear (Spencer &amp; Steyskal 1986). The widespread northeastern species L. asclepiadis makes blotch mines with at most a short linear portion; these are typically on the upper surface but are largely interparenchymal on A. incarnata L. (Eiseman &amp; Lonsdale 2018). Euphorbia is not a closely related plant genus, but has in common with Asclepias a milky latex that perhaps explains why this species would be attracted to both hosts.</p><p>The above specimens differ from the holotype in being slightly paler. The first flagellomere is dark yellow (not infuscated), the fore femur lacks dark outer markings, the posterolateral region of the scutum is yellow with very limited infuscation, the coxae are paler and the face does not appear to be brown centrally, although it is difficult to determine with the material available. These first known females are similar in wing length to the males, both being 1.4–1.8 mm.</p></div>	https://treatment.plazi.org/id/038B879BFFA3740212C0D862494BB5F7	Public Domain	No known copyright restrictions apply.

Other confirmed hosts not listed as new here were reported by Eiseman et al. (2019) under L. carphephori Eiseman, Lonsdale &amp; Feldman. Also see Comments.</p><p>Leaf mine. (Figs. 181, 182) Whitish to green or brown, linear, with frass typically in black, beaded or continuous strips (rarely squiggly, as in BG 534685). Mines on Bidens ( Coreopsideae) virtually always begin at the apex of a leaflet, where they are often highly contorted before meandering elsewhere in the leaf (Eiseman &amp; Lonsdale 2018: Fig. 160; Eiseman et al. 2019: Fig. 41). Mines of this type also occur on all hosts in Eupatorieae (Fig. 182) except perhaps Carphephorus, although they are less common on Ageratina and none of the Ageratina -reared specimens made this type of mine. The female from Ambrosia (Heliantheae) was reared from a mine of this type (BG 1877207). The mine on Rudbeckia (Heliantheae) was similarly contorted at the beginning but was initiated near the middle of the leaf (BG 1868669). On Carphephorus, the mine may be formed on either leaf surface; it is frequently formed mostly on the lower surface, switching to the upper surface toward the end (Eiseman et al. 2019: Figs. 42, 43). Mines that are not particularly contorted and switch from one leaf surface to the other also occur on other Eupatorieae (Fig. 181; Eiseman &amp; Lonsdale 2018: Fig. 162). Mines on Ageratina usually are not contorted and are usually confined to the upper leaf surface. In some of these Ageratina mines, and on some non-contorted mines on Eutrochium, there is very little visible frass (a few minute grains and irregular thread fragments may be present).</p><p>Puparium. (Fig. 55) Yellow to orange-yellow; formed outside the mine. On Ageratina, the puparium is sometimes glued with black frass to the lower leaf surface. On Mikania, we have found puparia stuck to either leaf surface (one example of each), but without the black frass lump.</p><p>Phenology and voltinism. This species is multivoltine. Larvae and puparia have been collected in early June (MA, NC), mid-June (CT, NC), late June (MA, NC, WI), early July (MA, NC), mid-July (NC, WI), late July (NC), early August (MA, NC), and mid-August (CT, MA, NC), with adults emerging 2–26 days later; one larva collected in mid-August (MA), and all larvae collected in early October (MA, VT), overwintered as pupae and emerged as adults the following spring (Eiseman &amp; Lonsdale 2018; Eiseman et al. 2019).</p><p>Distribution. USA: *CT, MA, NC, VT, *WI; Canada: ON, QC (Lonsdale 2017; Eiseman et al. 2019 (as L. carphephori)). The Illinois specimen that Eiseman et al. (2021) listed under Liriomyza cf. cracentis is here reidentified as L. eupatoriella Spencer. Also see Comments.</p><p>Comments. Although the leaf mines of Liriomyza cracentis are quite variable in form, those that begin with a highly contorted portion at the leaf tip seem safe to attribute to this species at this point, except in the southeastern USA, where L. archboldi may sometimes form similar mines on Bidens in Florida (see above), and where L. mikaniovora Spencer has now been reared from similar mines on Mikania in North Carolina (see below). Such mines have been found on additional Asteraceae genera related to the known hosts of L. cracentis, including Chromolaena DC., Conoclinium DC., Coreopsis L., and Fleischmannia Sch.Bip. The only other Liriomyza known to feed on Eupatoriae in northeastern North America is L. eupatoriella (below), on Ageratina, and we know of no way to determine which of the two species is responsible for non-contorted mines on this host without rearing adults. Liriomyza eupatorii (Kaltenbach) feeds on Eupatorium in Europe and has been reared from Mikania in Florida (Diaz et al. 2015), but it has never been associated with Eupatorieae in the rest of North America, where it is almost exclusively associated with Astereae (Eiseman et al. 2021) . Photographs on iNaturalist show leaf mines likely representing L. cracentis from Prince Edward Island and Nova Scotia to Florida, west to southern Ontario, Minnesota, eastern Nebraska, central Oklahoma, and the eastern half of Texas. We have also seen mines suggestive of L. cracentis in Colorado and Arizona.</p><p>Liriomyza cracentis (holotype genitalia in Figs. 402–404) and L. carphephori (holotype genitalia in Figs. 405– 408) are highly similar species, overlapping considerably in external appearance and genitalic morphology. Since the description of L. carphephori, additional reared material has become available that has provided host data for specimens consistent with the description of L. cracentis, blurred species boundaries with the observation of intermediate states, and made previously perceived differences appear insignificant. The holotype of L. carphephori originally appeared as distinct when examined, having a distiphallus that is wider and more barrel-shaped, an ejaculatory apodeme that is relatively atrophied, and a mesophallus that is much more squat, dorsally angled and with a pronounced ventral carina. It is now apparent that there are intermediate states that present a continuum between the extremes represented by the two holotypes.</p><p>As such, Liriomyza carphephori syn. nov. is here treated as a junior synonym of L. cracentis . The redefined species is here newly diagnosed as follows: Wing length 1.4–1.6mm (♂), 1.8–1.9mm (♀); length of ultimate section of vein M 4 divided by penultimate section: 2.2–4.4; eye height divided by gena height: 5.6–7.0; calypter margin and hairs grayish to brown; vertical setae on yellow ground; scutum dark with wide lateral yellow stripe and posterior margin very narrowly yellow in almost all specimens (note that the specimen from collection CSE7124 differs in having the black scutal spot very narrowly reach the scutellum, and as such, will not properly key using Lonsdale (2017)); anepisternum with small brown anteroventral spot; femora yellow and tibiae paler brown basally; surstylus with two spines; paraphallus short and very narrow along length; mesophallus narrowed dorsally, not more than half length of distiphallus; distiphallus subcylindrical with slight dorsoventral compression; distiphallus cup-shaped and narrow with sides nearly parallel (usually shorter with curved sides in similar species) and inner surface entirely smooth or with minute spicules that are difficult to discern (clearly visible in similar species).</p></div>	https://treatment.plazi.org/id/038B879BFFA2740012C0DD6B4CC1B527	Public Domain	No known copyright restrictions apply.

(Eiseman &amp; Lonsdale 2018) refers to specimens that are described below as Liriomyza konza, sp. nov.</p><p>Leaf mine. (Eiseman &amp; Lonsdale 2018: Figs. 138, 159; Eiseman et al. 2021: Fig. 74) Whitish, linear, 1–2 mm wide at the end, with diffuse greenish frass for most of the mine’s length, but with some dark green to black grains and irregular streaks toward the end.

Larvae and puparia have been collected in early June (MA), mid-June (IL, MA), mid-July (IA), and mid-September (WI), with adults emerging 2–22 days later (Spencer &amp; Steyskal 1986; Eiseman &amp; Lonsdale 2018).</p><p>Distribution. USA: IA, *IL, MA, MD, VA, WI; * Canada: QC (Eiseman &amp; Lonsdale 2018; Lonsdale 2021). The record of KS (Eiseman &amp; Lonsdale 2018) refers to Liriomyza konza sp. nov. Spencer &amp; Steyskal’s (1986) record of MN, based only on empty leaf mines, requires confirmation (see below).</p><p>Comments. Leaf mines of Liriomyza eupatoriella do not appear to be reliably distinguishable from those of L. cracentis on Ageratina . The two species even share the habit of gluing the puparium to the lower leaf surface with black frass—which, curiously, has not been observed on any other host plant for L. cracentis (or in the two new species on Vernonia, L. konza and L. nyx, which are closely related to L. eupatoriella). The Ageratina- reared Illinois specimen that was discussed by Eiseman et al. (2021) under the heading “ Liriomyza cf. cracentis Lonsdale ” is now accepted as representing L. eupatoriella, as is the Massachusetts female discussed by Eiseman &amp; Lonsdale (2018) as “ Liriomyza sp. 2 .”</p><p>Liriomyza eupatoriella can be differentiated from most other Liriomyza externally by a combination of characters: the posterior margin of the mostly dark scutum is narrowly yellow; the anepisternum is mostly yellow with a small brown anteroventral stripe that may be strongly reduced; the first flagellomere is small, round, and yellow; the orbit is unenlarged; the wing length is 1.6–2.0 mm; and the calypter margin is grayish to brownish and the hairs are brownish-gold. This description largely overlaps that of L. cracentis, however, which has similar genitalia (Figs. 402–408): the surstylus has two spines, the paraphallus is narrow, the mesophallus is short with a ventral carina, and the distiphallus is small and cup-shaped. To differentiate the two species, differences of the genitalia must be examined. Liriomyza eupatoriella (Figs. 409–411) differs as follows: basiphallus weakly sclerotized apically on both sides (not well sclerotized); paraphallus at least as wide as left distal margin of basiphallus and sometimes much widened apically (not short, narrow and rod-like); mesophallus with venter and dorsum subequal in length (not narrowed dorsally); mesophallus total length more than half length of distiphallus (not half as long or less); distiphallus smaller, more obviously compressed dorsoventrally and with easily viewed spinules on inner-distal margin (not absent to pale and reduced).</p><p>The Wisconsin holotype of Liriomyza eupatoriella was reared from Ageratina altissima, and following dissection of additional specimens from this host (male from collection event CSE1797 illustrated), it is now apparent that this entity includes the non-type specimen of L. cracentis from Quebec described in the variation section of the original description as “type 3” (Lonsdale 2017: Figs. 260–263). The “type 3” specimen and other Ageratina reared specimens only differ from the holotype in being slightly larger (wing length 2.0 mm, expanding the known male wing length of this species to 1.6–2.0 mm), the ratio of the ultimate section of vein M 4 divided by the penultimate is slightly smaller (2.0–2.2; 3.0 in holotype), and the brown stripe on the anepisternum is sometimes reduced to a small pale spot. With regard to the genitalia, the surstylar spines are closer to each other medially, the basal half of the basiphallus is narrow and slender, the paraphallus is simple and narrower (in the illustrated male from Iowa the apex is much expanded, appearing L-shaped), the mesophallus is longer than wide and only half as wide as the distiphallus, the distiphallus has a rounded base and is thickest medially (ventral view), and there is a wider band of spines along the inner subapical margin.</p><p>Liriomyza eupatoriella is also similar to two closely related species reared from Vernonia that are described here as new: L. konza from Kansas, and L. nyx from North Carolina. Both of the new species differ from L. eupatoriella in having six (not four) rows of acrostichal setulae, the calypter hairs are yellow (not with brownish tint), the markings on the pleuron are much reduced, the tibiae are much paler, the surstylar spines are more apical in position, the basiphallus has a longer dorsal surface and its basal left lateral extension is reduced, the mesophallus is thicker (not half the width of the distiphallus) and the base of the distiphallus is less rounded.</p><p>The adult of Liriomyza konza (Figs. 412–415) is the palest of these species, having a faded ocellar spot, an entirely yellow band around the eye, the anatergite is only brown ventrally, the brown marking on the anepisternum is reduced to a minute faded spot, the anepimeron is entirely yellow, and the tibiae are entirely yellow. Internally, the paraphallus is relatively thick with a pointed, straight apex (not broad and upcurved), and there is a narrow, pale groove along most of its length; the mesophallus is almost as high as the distiphallus and about ⅔ as wide, and the ventral carina is shallower; the distiphallus is slightly wider with a thicker base and medial constriction. Wing length is 1.6–1.7 mm; the M 4 vein ratio is 3.0–3.3.</p><p>Liriomyza nyx (Figs. 416–418) is darker (hence the name), with a thicker spot on the anepimeron that is subrectangular in outline, the narrowest part of the notal spot (near the anterior margin) is flanked on either side by a brownish patch, and the tibiae are only faintly brownish (not brown). Internally, the paraphallus is uniformly thick throughout, it is strongly upcurved at the midpoint, and the apex is darker and straighter along the distal margin; the mesophallus is as long and as thick as the distiphallus, and the ventral surface is shorter than the dorsal surface; the distiphallus (ventral view) is of nearly uniform width along its length with the apex slightly wider. Wing length is 1.8–2.0 mm; the M 4 vein ratio is 2.4–2.6.</p></div>	https://treatment.plazi.org/id/038B879BFFA0740712C0DC1A4A0BB2A3	Public Domain	No known copyright restrictions apply.

California specimens apparently reared from Callistephus Cass. ( Asteraceae) have been tentatively identified as L. eupatorii (Lonsdale 2011) . Eiseman et al. (2021) mentioned mines found on Senecio triangularis Hook. in Idaho as likely representing this species, but there are otherwise no records of L. eupatorii from hosts in the tribe Senecioneae, and these mines may actually have been made by another species such as L. temperata Spencer (Eiseman et al. 2024a).</p><p>Leaf mine. Linear, often beginning with a spiral; see Eiseman &amp; Lonsdale (2018, including Fig. 140).</p><p>Puparium. Yellow to dark brown; formed outside the mine (Eiseman &amp; Lonsdale 2018).</p><p>Phenology and voltinism. This species is multivoltine, although we have only collected larvae and reared adults prior to midsummer (Eiseman et al. 2021); an Alberta specimen emerged on 19 August from a larva collected on 4 August (Lonsdale 2017), and occupied mines were recently found in Washington as late as 13 August. The earliest record for larval activity in the eastern USA is a collection from North Carolina on 14 February, which produced an adult female by 3 March (specimen lost).</p><p>Distribution. USA: [AL], *AR, CA, [CT, DC], DE, [FL], GA, *IA, [ID], IL, [IN, KY, LA], MA, MD (Lonsdale 2021), [ME], MI, [MN, MO], MS, MT, NC, [NH, NJ], NY, [OH], OK, PA, [RI], SC, TN, [TX], VA, [VT], WA, [WI], WV; Canada: AB, BC, MB, NB, [NL], NS, ON, [PE], QC, SK; Europe (Eiseman et al. 2021).</p><p>Comments. With the exception of a single record of Liriomyza trifolii (Burgess) being reared from Symphyotrichum cordifolium in a greenhouse experiment (Smith &amp; Hardman 1986), we have seen no evidence that any Liriomyza other than L. eupatorii feeds on Solidago or Symphyotrichum spp. in North America. Three polyphagous species that occur here have been reported from Solidago elsewhere: L. huidobrensis (Blanchard) in Spain, China, and Kenya (Weintraub et al. 2017), and L. sativae Blanchard and L. trifolii in unspecified countries (Benavent-Corai et al. 2005). When mines on these hosts do not begin with the characteristic spiral, the frass pattern must be studied closely to rule out species of the Phytomyza albiceps group. In general, the frass of these Phytomyza species is in discrete grains rather than in strips, but P. ciliolati Spencer (on Canadanthus and Symphyotrichum) produces frass in very long strips, sometimes appearing as an almost continuous line (Griffiths 1976). Although specimens of P. ciliolati are known only from Alberta, it may be the species that Frost (1924) reported rearing from Symphyotrichum spp. in New York (as P. albiceps Meigen) and that Eiseman &amp; Lonsdale (2018) discussed as “ Phytomyza sp. 2 ” (from Iowa). Although the strips in these eastern Phytomyza mines are often much longer than in L. eupatorii mines, they can be of similar length, and when this occurs it becomes clear that a Phytomyza is responsible only after the larva exits and forms a blackish (rather than yellow to brown) puparium.</p></div>	https://treatment.plazi.org/id/038B879BFFA7740512C0DB9E4C86B23A	Public Domain	No known copyright restrictions apply.

(Fig. 183) According to Spencer &amp; Steyskal (1986), a “short linear mine, with frass in greenishblack strips.” Sehgal (1971) described the mine as a small blotch with a short linear beginning. The Trifolium mine examined by Eiseman &amp; Lonsdale (2018: Fig. 141) was whitish and essentially linear, but it widened dramatically and contorted to form a secondary blotch; the dark green frass particles were deposited rather irregularly, loosely arranged into alternating elongate patches unlike the distinct strips seen in other Liriomyza mines. The new mine on Lathyrus (= Pisum) was likewise linear throughout, with irregularly deposited black frass particles that were sometimes arranged in alternating loose groups but never formed strips.</p><p>Puparium.

Two related Nearctic species may also mine leaves of Galium spp. or other Rubiaceae . Liriomyza vockerothi (Spencer) is known from a single male collected in Macon Co., North Carolina, and has not been associated with any host. Since our collections of mines on three different Rubiaceae genera in North Carolina (and from Galium spp. elsewhere) have yielded only adults of L. galiivora, we have accepted photographed leaf mines found on these plants in eastern North America as representing L. galiivora . Liriomyza turneri (Spencer) was described from a single male caught in El Dorado Co., California, and Spencer (1981) tentatively associated with this species two females that were reared from G. aparine and G. trifidum L. collected in the same county. Because of this, we have omitted purported L. galiivora records on iNaturalist from California and coastal Oregon and Washington, including mines found on G. oreganum Britton in Oregon (iNat 89434981), and on G. porrigens Dempster (iNat 121838423) and G. sparsiflorum W.Wight (iNat 185937466) in California. Liriomyza galiivora has been confirmed as far west as Alaska and British Columbia in the north, but in the lower 48 states the westernmost records confirmed by reared specimens are from Minnesota and Iowa, and our two observations on Galium in Idaho and Colorado, listed above, are the only leaf mines on Rubiaceae that have been documented between the Pacific Coast states and eastern Kansas / Oklahoma.</p></div>	https://treatment.plazi.org/id/038B879BFFA4740B12C0DC1A4A10B26B	Public Domain	No known copyright restrictions apply.

Liriomyza hilairensis is differentiated from other members of the huidobrensis group by the shape of the distiphallus (but similar to L. huidobrensis), two surstylus spines (not one), and pale coloration (Lonsdale 2017: Figs. 337–340). The Wisconsin specimen differs from known Canadian specimens by having the posterolateral spot on the frons fading to yellow towards the base of the outer vertical, the spot on the anepisternum is very small, and the fore femur has no brown streaking.</p></div>	https://treatment.plazi.org/id/038B879BFFAA740A12C0DF1E4A14B321	Public Domain	No known copyright restrictions apply.

Four dorsocentral setae, decreasing in length anteriorly (fourth seta only slightly more than ¼ length of first).Acrostichal setulae in six irregular rows, extending just past level of second dorsocentral, and with two pairs of cruciate setulae between level of first and second dorsocentrals.</p><p>Coloration: Setae black.Ocellar spot pale brown, not large enough to enclose ocelli; posterolateral corner of frons with brown region not extending to margin of eye or vertical setae; back of head dark brown on dorsal half. Calypter margin yellowish-gray, hairs yellow. Anterior margin of notum brown with spot extending onto postpronotum; scutum with dark brown medial spot widely separated from lateral margin, with spot narrowest anteriorly (restricted to space between dorsocentral rows), constricted at suture, and widest postsuturally; posterior margin of scutum yellow with margin of brown spot undulating, being closest to posterior margin medially, encompassing base of first dorsocentral and avoiding base of posterior intra-alar.

These specimens were identified as Liriomyza eupatoriella by Eiseman &amp; Lonsdale (2018), while noting that the slight genitalic differences may indicate a sister species. Eiseman &amp; Lonsdale (2018) noted that no other Nearctic Liriomyza had been reared from Vernonia; the record of L. trifolii from this host was based on an empty mine that was only tentatively associated with that species. A second species on Vernonia, L. nyx sp. nov., is described below. Based on our observations thus far, the mines of L. nyx differ in the early portion, which is not contorted and is frequently on the lower leaf surface.

Wing length approximately 1.8–1.9 mm (♂), 1.9–2.0 mm (♀). Length of ultimate section of vein M 4 divided by penultimate section: 2.3–2.5. Eye height divided by gena height: 2.7–3.6. First flagellomere of male enlarged, almost ⅓ higher than pedicel; hairs along venter and distal margin longer, about half length of segment, yellow. Female first flagellomere with entire surface long-haired; segment not lengthened, but up to ⅔ higher than pedicel, resulting in kidney-shaped appearance. Anterior section of orbital plate and most of parafacial slightly pronounced, easily viewed laterally. Scutum almost shining, with faint pruinosity.</p><p>Chaetotaxy: Two ori, with anterior ori setula-like to ½–⅔ length of posterior seta; two ors (anterior seta more strongly incurved, as in ori). Ocellar and postvertical setae subequal to ors but thinner. Orbital setulae few, but dark and relatively large. Four dorsocentrals, decreasing in length anteriorly (fourth seta about half length of first). Four rows of acrostichal setulae.</p><p>Coloration: Setae black. Head mostly yellow; first flagellomere deeper yellow; back of head and clypeus dark brown; posterolateral corner of frons dark brown to level of inner vertical; ocellar tubercle enclosed by semicircular spot confluent with spot on back of head; female with very narrow brown line along outer margin of orbital plate. Notum dark brown to black with yellow lateral stripe that is faded along posterior margin near scutellum. Scutellum dark brown laterally. Mediotergite dark brown; anatergite and katatergite brown with large yellow region in anterodorsal corner of katatergite. Pleuron yellow with brown markings; anepisternum with small oblique anteroventral spot; anepimeron with single anterior stripe; katepisternum with large spot that does not reach level of seta; meron brown with dorsum yellow. Calypter margin and hairs brown. Legs mostly yellow; basal margin of coxae narrowly dark brown; hind coxa with light brown mottling; tibiae light brown (darker on hind leg); tarsi light brown. Abdominal tergites dark brown dorsally; epandrium brown; sternites yellow with irregular brown mottling.</p><p>Genitalia: (Figs. 419–421) Epandrium well-developed with one spine; articulating with surstylus. Cercus well-developed. Surstylus with two apical spines; left surstylus with additional paler apical spine. Phallophorus chair-shaped. Basiphallus with broad left lateral plate and limited dorsal sclerotization. Paraphallus elongate, slightly wider apically. Hypophallus narrow, with base widened and several apical hairs. Mesophallus fused to distiphallus, narrowing apically; dorsal and lateral surfaces thick, dark (contrasting paler distiphallus); ventral carina shallow, irregular, more developed basally where fossa is evident. Distiphallus slightly shorter and narrower than mesophallus; broadest near base, nearly straight sides narrowing apically to one pair of C-shaped bands bordering opening; circular in lateral view with nearly clear central spot, and with few internal spicules sunken below apex. Ejaculatory apodeme not recovered.</p><p>Comments. Although Lobelia cardinalis, L. inflata, and L. siphilitica are all reasonably common in New England, we have found no leaf mines of any kind on these plants there. The distribution of Liriomyza lobeliae appears to be restricted to the Midwestern USA, adjacent Canada, and the southern Appalachians.</p><p>The first flagellomere is immediately characteristic of Liriomyza lobeliae, with the length of the hairs being up to half the length of the body of the flagellomere. The segment is also enlarged in both sexes, with that of the female being more kidney-shaped in outline. Unusual features of the genitalia include the basally widened hypophallus, reduction of the basiphallus on the right side, a fused mesophallus/distiphallus that narrows distally aside from a shallow medial constriction (ventral view), and in lateral view, the mesophallus has an irregular ventral carina that is strongly developed basally with a ventral fossa, and the distiphallus is circular with a nearly clear central spot.</p><p>Similarly enlarged flagellomeres are seen in species of the Liriomyza hieracii group, particularly in females, but the new species does not appear to belong here, lacking all of the features definitive of that clade (see Xuan et al. (2023)). The two apical surstylus spines, chair-shaped phallophorus, and the general structure of the fused mesophallus/distiphallus place this species in the L. brassicae group, but determining potential sister species has been difficult. Other miners on Campanulaceae belong to the morphologically distinct L. strigata group, as well as the polyphagous L. trifolii, and L. buhri Hering and L. triodanidis Eiseman, Lonsdale &amp; Feldman, the last two of which have one pair of long, membranous tubules on the phallus.</p></div>	https://treatment.plazi.org/id/038B879BFFA8740F12C0DD334B1DB24E	Public Domain	No known copyright restrictions apply.

This species would seem to be the “ Liriomyza sp. ” listed by Diaz et al. (2015), but the host given for the undetermined species in that publication was Mikania cordifolia (L.f.) Willd. rather than M. micrantha . Diaz et al. (2015) listed M. micrantha and M. scandens as hosts for L. eupatorii, which agrees with the label data listed by Lonsdale (2021). Diaz et al. (2015) did not report any other associations of Liriomyza spp. with Mikania spp.</p><p>Liriomyza mikaniella can be allied to L. mikaniovora (Figs. 426–429) on the basis of not only a shared host genus (although no host species are known to be shared), but also highly similar external coloration and an enlarged, curved spine on the surstylus. External characters useful for diagnosing Liriomyza mikaniella are as follows: distal margin of first flagellomere with long hairs; scutum without two pairs of medial cruciate setae in otherwise bare region between first and second dorsocentrals; posterior intra-alar seta touching or enclosed by brown scutal spot (rarely occurring in L. mikaniovora); brown lateral spot on scutellum reaching base of lateral seta; the abdominal pattern is characteristic (not simply brown dorsally with posteriorly widening lateral yellow stripe). Internally, there are a number of differences with the structure of the phallus being unusually dissimilar: there is only one long, incurved surstylar spine (not two); the basiphallus has a single long lateral plate with a small dorsomedial extension (not with long dorsal plate and pointed left lateral extension); the mesophallus is weakly sclerotized ventrally, without a carina, and it is dorsally fused to a cup-shaped distiphallus with a pad of minute spinules inner-distally (not cylindrical with several larger inner-marginal spines).</p></div>	https://treatment.plazi.org/id/038B879BFFAF740E12C0DBB04B4AB113	Public Domain	No known copyright restrictions apply.

NORTH CAROLINA: Craven Co., Croatan National Forest, near Brices Creek, 28.vi.2022, em. 16–18.vii.2022 , T.S. Feldman, ex Mikania scandens, # CSE7618, CNC5173591–8 (4♂ 4 puparia); Dare Co., near Nag’s Head Woods, site 2 goatman, 25.v.2022, em. 6–7.vi.2022 , T.S.

Spencer (1♀ [holotype, photos], NHMUK); Merida, 8.v.1972 (1♀ [photos], NHMUK) .</p><p>Hosts. Asteraceae: Mikania *scandens (L.) Willd.; known from M. cordifolia (L.f.) Willd. in Venezuela (Spencer 1973).</p><p>Leaf mine. (Fig. 189) According to Spencer (1973), an “unusually long slender mine.” The mines from which this species was reared in Craven Co., North Carolina began at the leaf tip and were initially highly contorted, just like the mines the related species L. cracentis commonly makes on this and related plants. The mines in Dare Co. did not begin at the leaf tip, were not contorted, and alternated between the upper and lower leaf surfaces, as other mines of L. cracentis frequently do. In both cases, the mines were whitish with frass in black strips along the sides.</p><p>Puparium. (Fig. 62) Straw-colored when empty; formed outside the mine.</p><p>Phenology and voltinism. This species is evidently multivoltine. In North Carolina, larvae have been collected in late May and late June, with adults emerging 12–20 days later.</p><p>Distribution. * USA: NC; Venezuela (Spencer 1973).</p><p>Comments. Based on the new material available, including the first known male, the definition of this species can be expanded as follows (Figs. 61, 63–65, 426–429): wing length 1.4–1.9 mm (♂), 1.7 mm (♀); length of ultimate section of vein M 4 divided by penultimate section 2.5–2.7; eye height divided by gena height 6.7–10.8. Setae black; bases of outer vertical setae either surrounded by yellow ground or with brown spot reaching base of outer vertical (holotype female only); distal margin of first flagellomere with longer hairs (length about twice width of base of arista); clypeus yellow, sometimes with brownish tint. Scutum shining black with wide lateral yellow stripe that is wider at anterior margin and transverse suture; posterior margin of scutum with wide yellow stripe that becomes extremely narrowed along posterior margin, with yellow line sometimes barely exceeding width of one to several setae, or even entirely absent; posterior dorsocentral within brown spot and posterior intra-alar surrounded by yellow in region posterior to spot (paler brownish extension of spot reaching this seta in Venezuelan non-type); acrostichal setulae in four rows that narrow to two and disappear at or just behind level of second dorsocentral, with only two pairs of cruciate setulae in otherwise bare space between posterior dorsocentrals; anepisternum with small (only NC specimens) to slightly elongate brown anteroventral spot (some NC specimens and non-type Venezuelan specimen), or with larger pale brown region covering most of anteroventral corner (holotype only). Legs yellow with tibiae and tarsi brownish (fore leg paler). Abdominal sternites yellow; tergites brown with wide lateral yellow stripe that becomes wider on posterior segments; very narrow yellow line medially on T2. The surstylus is visible laterally and has two very long spines; the basiphallus has long basal projections on the left distal, dorsal and left lateral surfaces; the paraphallus is dark and rod-like; the mesophallus is short dorsally and much longer ventrally with a shallow carina; the distiphallus is separate from the mesophallus, short, subcylindrical with the apex slighter expanded, and with an apical ring of small spinules on the inner surface.</p><p>The newly available material has greatly extended the known distribution of this species, whose host extends from South America into the United States. Aside from the inclusion of male genitalic features, the diagnosis of this species is now updated to note that the posterior margin of the scutum is sometimes not entirely yellow as previously assumed, with the narrow medial line sometimes absent, and likely not visible in poorly preserved specimens.</p><p>The two exceptionally long, curved spines on each surstylus of Liriomyza mikaniovora is diagnostic, and very unusual in the family. A similar single spine is seen on the surstylus of L. mikaniella, and while this uncommon character and host genus suggests a close relationship, minutiae of the genitalia suggest that the character might be independently derived. In L. mikaniella, the basiphallus is more slender, and not developed on the right basal side or the left distal side, and the mesophallus is dorsally fused to a rounder distiphallus and not carinate ventrally. A few additional species share a single long spine, including L. paumensis Spencer, L. biensis Boucher, and L. monoensis Spencer, but these also have otherwise dissimilar genitalia, especially in the structure of the distiphallus, and are likely unrelated.</p></div>	https://treatment.plazi.org/id/038B879BFFAE740D12C0D80E4920B16E	Public Domain	No known copyright restrictions apply.

The type series was swept from “open grass” (Sehgal 1968).</p><p>Leaf mine. The only photograph taken of leaf mines in connection with this rearing shows a leaf with three confluent mines flanking the midrib, which we suspect represent Agromyza bispinata . Photographs of puparia taken at the time the adult emerged show more than three different puparia, so clearly the collection included more than this one leaf, and we presume the Liriomyza montana larva made a narrow mine that appeared superficially similar, or perhaps it was on the underside of a leaf and never observed at all. The related species L. flaveola (Fallén) forms a narrow, whitish, entirely linear mine on either leaf surface, which generally runs down the leaf from the apex and often follows the margin, with frass in large dark grains that alternate along the sides (Ellis 2024).</p><p>Puparium.

As noted by Eiseman &amp; Lonsdale (2019), it is unclear what evidence Spencer’s (1990) statement that L. sativae has “colonized” Phlox in Arkansas is based on, as there are no published records of any Liriomyza other than L. phloxiphaga being reared from this host in North America. We suspect that Spencer only observed vacated mines of L. phloxiphaga, and we note that Spencer &amp; Steyskal (1986) did not list Arkansas among the known localities for L. sativae, nor have any specimens been reported from that state since then. Spencer (1990) also stated that L. trifolii has colonized Phlox in Kenya, and it is conceivable that this species could occasionally mine Phlox leaves in North America, but we consider it highly unlikely that either of these species is responsible for any of the photographed mines listed above. When fresh, mines of L. phloxiphaga are green and indistinct, only later turning whitish, whereas mines of L. sativae and L. trifolii are conspicuous and whitish even when occupied.</p><p>No agromyzid has yet been reared from Polemonium L., and it may be that L. phloxiphaga is responsible for linear mines found on P. reptans L. in Delaware (iNat 296367000), Illinois (iNat 313735023), Iowa (BG 1631566), Minnesota (BG 1578571, 1578573; iNat 56472120, 56982971, 97014655), and Pennsylvania (iNat 303554579), and on Polemonium sp. in Ohio (iNat 173601295). A linear-blotch mine found on P. californicum Eastw. in Oregon (iNat 181701676) clearly represents a different species. One other Polemoniaceae host on which linear Liriomyza mines have been found is Collomia grandiflora Douglas ex Lindl., in British Columbia (iNat 183403487).</p></div>	https://treatment.plazi.org/id/038B879BFF5174F112C0DEE64D51B1DF	Public Domain	No known copyright restrictions apply.

Mesophallus not visible. Distiphallus with one pair of partially fused, shallowly undulating tubules that are dark and almost as long as remainder of phallus; base surrounded by dark bowl that is incomplete on left side and fringed by numerous long pointed projections. Ejaculatory apodeme not recovered.</p><p>Comments. Liriomyza rivinae is an unusual species most closely related to L. valladaresae Carvalho-Filho, Almeida &amp; Esposito and L. pectinimentula Sasakawa. Liriomyza valladaresae is known from “ Alternanthera tenella ” (= A. ficoidea (L.) P.Beauv. or A. sessilis (L.) DC.) and Amaranthus viridis L. ( Amaranthaceae) in Brazil (Pará) and Argentina (Carvalho-Filho et al. 2016) . While L. valladaresae is a larger species with a narrower yellow line along the posterior margin of the scutum, the relationship is clearly seen through the long, sinuous distiphallus and the reduced, rounded surstylus with only three apical setae and no spines. Liriomyza rivinae further differs from this species in having a posteromedial seta on the mid tibia, which is quite unusual in the genus, and much paler coloration, including calypter hairs that are golden (not brown). Liriomyza pectinimentula is known from two unreared males from El Salvador (Sasakawa 2005). This species differs in having a brown-tinted region ventromedially, the posterior intra-alar setae are surrounded by yellow, the wing is 1.4–1.6 mm long, the surstylus has 2 terminal setae with 1 or 2 minute spines, the hypophallus does not appear to be surrounded by several flat sclerotized plates, and the tubules of the distiphallus are more strongly curved.</p><p>Compared to Nearctic congeners, Liriomyza rivinae differs strikingly in genitalic morphology. The surstylus is much reduced with only three long setae, the phallophorus and the short, symmetrical basiphallus are unique, the swollen section of the ejaculatory duct is very dark and basally slender, and the hypophallus has numerous clustered hairs inserted into the membrane and three irregular sclerotized patches. Most diagnostic, however, is the distiphallus, which has long, dark, undulating tubules and a dark, basal cup-like section that is incomplete on the left side and fringed by long pointed projections.</p></div>	https://treatment.plazi.org/id/038B879BFF5074F612C0D89B4AE0B65B	Public Domain	No known copyright restrictions apply.

Palmer, ex Cirsium altissimum, # CSE4964, CNC1643657–9 (2♂ 1♀) .</p><p>Hosts. Asteraceae: Carduus pycnocephalus L., Cirsium *altissimum (L.) Spreng., C. arvense (L.) Scop., Cirsium brevistylum Cronquist (originally reported as C. edule Nutt., corrected by Spencer &amp; Steyskal (1986)), C. congdonii R.J.Moore &amp; Frankton, C. *douglasii DC., C. tioganum (Congdon) Petr., C. vulgare (Savi) Ten., Dahlia imperialis Roezl ex Ortgies, Pseudognaphalium leucocephalum (A.Gray) Anderb., Silybum marianum (L.) Gaertn.; Lamiaceae: Salvia mellifera Greene (Spencer 1981; Lonsdale 2011). Spencer (1981) listed a single male collected as an adult on Baccharis pilularis DC., and there are no rearing records from this host as implied by Spencer &amp; Steyskal (1986). Other California specimens labeled “ex. Bidens pilosa ” and “ex. Marigold” (Lonsdale 2011) may or may not have been reared.</p><p>Leaf mine. According to Spencer (1981), an “irregular linear mine, not infrequently associated with the midrib and stronger lateral veins.” The mines we observed (e.g., BG 1839362, 2122026) were upper-surface and largely whitish, in some cases partly greenish (interparenchymal) or with some brown discoloration, and were narrowly linear (~ 1 mm wide) with frass in black strips along the sides. We would not describe them as irregular or particularly associated with the midrib or lateral veins. The mines frequently began near the leaf apex or near the apices of lobes, with mines of up to six or more larvae beginning in a confused jumble.</p><p>Puparium. Yellow to orange (Spencer 1981); formed outside the mine.</p><p>Phenology and voltinism. This species is clearly multivoltine in California, where reared specimens are labeled with (presumably emergence) dates in mid-April, early May, late May, late June, early July, mid-July, late July, late August, mid-September, early November, and early December. Washington specimens have emerged in early August and early June (Spencer 1981; Lonsdale 2011). We have collected larvae in late May (NC), early June (OK), and late June (NC), with adults emerging 13–18 days later.</p><p>Distribution. USA: CA, *NC, *OK, WA; Canada: BC, MB; Colombia; Costa Rica; Venezuela (Lonsdale 2017).</p><p>Comments. Spencer’s (1981) statement that this species is known from Astereae, Cynareae, Heliantheae, and Inuleae needs some adjustment. The correct name for Cynareae is now considered to be Cardueae, which includes thistles and their relatives, and nearly all North American rearing records are from these plants, with a few from Coreopsideae ( Dahlia Cav. and possibly Bidens L.), Gnaphalieae ( Pseudognaphalium Kirp.), and one nonasteraceous host ( Lamiaceae: Salvia L.). There has never been a rearing record from Astereae, only a single male caught on Baccharis L. (Spencer 1981), and no recorded hosts are now placed in Heliantheae or Inuleae. Central and South American host records summarized by Lonsdale (2011, 2017) include plants now placed in Eupatorieae ( Piqueria Cav.) and Millerieae ( Galinsoga Ruiz &amp; Pav.).</p></div>	https://treatment.plazi.org/id/038B879BFF5674F612C0DFC64B7DB017	Public Domain	No known copyright restrictions apply.

We now suspect the lower-surface mines on Annona glabra L. ( Annonaceae) mentioned by Eiseman et al. (2019) may have been caused by a Phyllocnistis species ( Lepidoptera: Gracillariidae).</p><p>Leaf mine. (Eiseman et al. 2019: Figs. 47–48) A silvery, epidermal, irregular serpentine mine, usually on the upper leaf surface. We have seen a few examples of empty lower-surface mines on Passiflora and Smilax, and larvae apparently of this species have been found mining a young Smilax stem.</p><p>Puparium. Yellow to brown; formed outside the mine.</p><p>Phenology and voltinism. This species is multivoltine, with larvae observed or collected in Florida in late March, late April, mid-June, mid-July, and early October; adults have emerged 11 days after larval collections (Spencer &amp; Stegmaier 1973). In North Carolina, larvae have been collected in late July, mid-August, and late August, with adults emerging 13–22 days later (Eiseman et al. 2019).</p><p>Distribution. USA: [AL, DC], FL, [GA, IL, IN, LA, MD, MS], NC, [NJ, PA, SC, TN, TX, VA; Canada: ON]; Argentina (Valladares 1984); Bahamas; Costa Rica; Jamaica (Eiseman et al. 2019).</p><p>Comments. Our new specimens include the first successful rearing of this species from Smilax; Spencer &amp; Stegmaier’s (1973) record of an unspecified Smilax host was based on examination of a puparium. Until Eiseman et al. (2019) reported specimens reared from Gelsemium in North Carolina in 2017, the geographic distribution of Liriomyza schmidti was believed to extend only from South America to Florida (Spencer 1990) . Photographed leaf mines now reveal a continuous distribution in the coastal states of the southeastern USA from Texas to New Jersey, as well as in adjacent Tennessee, and with apparently disjunct populations along Lake Michigan and Lake Erie in Illinois, Indiana, Pennsylvania, and Ontario. Although L. schmidti is extremely polyphagous in the Neotropics including southern Florida, with records from over 30 different plant families, the host range apparently is dramatically reduced northward, with all observations north of North Carolina being on Smilax spp., and with most observations north of southern Texas and southern Florida being on Smilax, Passiflora, Gelsemium, and Erythrina .</p></div>	https://treatment.plazi.org/id/038B879BFF5474FA12C0DEE64DF2B335	Public Domain	No known copyright restrictions apply.

Most of the mines from which the new Krigia specimens were reared rapidly expanded to blotches, as in typical mines on Taraxacum (Eiseman &amp; Lonsdale 2018: Fig. 153), and were not entirely linear as reported from Krigia mines by Eiseman et al.

Larvae have been found on Krigia spp. in North Carolina from late March to late April, and with the exception of a single female that was found dead and moldy a month later (CSE7403), all have overwintered as pupae, emerging as adults the following spring.

With confirmation of the host, location and morphology, evidence is accumulating to possibly support this phenotype as a separate species, but the boundaries of L. taraxaci are too convoluted at present to arrive at a confident decision, and molecular data may be required to efficiently tease apart any cryptic taxa presently lumped within this species.</p></div>	https://treatment.plazi.org/id/038B879BFF5A74F912C0DA2D4DF3B55E	Public Domain	No known copyright restrictions apply.

This is the first record of any leaf-mining agromyzid on Borrichia; Melanagromyza minimoides Spencer feeds in seed heads of B. frutescens (Spencer &amp; Steyskal 1986) . Although our specimen from this host is an underdeveloped female, it matches the specimens reared from Canavalia . One of the Canavalia- reared specimens is a male with genitalia that agree with the description of Liriomyza trifolii, and externally they match a relatively small subset of specimens characterized by a slightly larger wing length and limited additional pigment on the femora, at the base of fronto-orbitals, and along the posterolateral margin of the eye (Lonsdale 2017). There are no prior records of Agromyzidae from Canavalia in North America, although both L. sativae and L. trifolii are recorded from this host elsewhere (Benavent-Corai et al. 2005). Both Borrichia and Canavalia are fleshy-leaved plants that grow along the immediate coast.</p></div>	https://treatment.plazi.org/id/038B879BFF5974F812C0DCC34A6BB4F7	Public Domain	No known copyright restrictions apply.

Since this is the only Nearctic Liriomyza known to feed on Valeriana, we presume the leaf mine found on V. officinalis in Minnesota also represents this species. In western Canada (YT, BC), Phytomyza kluanensis (Griffiths) has been reared from V. capitata Pall. ex Link and V. sitchensis Bong.; its mines can be distinguished from those of L. valerianivora by the frass in discrete particles and the puparium formed within the leaf (Griffiths 1974b). A Liriomyza, which may or may not be L. valerianivora, also occurs on these hosts in western North America. Hansson (1987) listed a specimen of Chrysocharis viridis (Nees) ( Eulophidae) reared from a Liriomyza sp. on V. capitata in Yukon. Liriomyza mines have been photographed on V. sitchensis in British Columbia (iNat 133261693, 136518782, 139704926, 176219628, 187032983, 187039933) and Washington (iNat 176886672, 194562037).</p></div>	https://treatment.plazi.org/id/038B879BFF5874F812C0DA6A4D02B0AB	Public Domain	No known copyright restrictions apply.

Prior to this study, the only Liriomyza recorded from Rudbeckia was the polyphagous Palearctic species L. strigata (Meigen), known from R. hirta and R. laciniata (Ellis 2024) . Three Nearctic Liriomyza species have now been reared from Rudbeckia, all of them Asteraceae specialists as far as is known, including L. arctii from R. laciniata, L. cracentis from R. subtomentosa, and L. hilairensis from R. hirta . Of these three, the contorted beginning of the mine on R. triloba is suggestive of L. cracentis, which is common in North Carolina, but this female specimen is too underdeveloped with no pigment to evaluate this possibility.</p></div>	https://treatment.plazi.org/id/038B879BFF5E74FE12C0DC8A4C2DB26B	Public Domain	No known copyright restrictions apply.

Two North American agromyzid species have been reported from Tridax previously. Liriomyza trifolii has been reared from T. procumbens in Florida (Stegmaier 1966), and L. sativae is recorded from Tridax outside of North America (Benavent-Corai et al. 2005). This female differs from these species in having more pronounced hairs along the distal margin of the first flagellomere, possibly suggesting placement in the L. hieracii group. Other features of note include only one ori, vertical setae that are enclosed by or touching brown pigment, and the frontal vitta is very narrowly brown along the eye margin; tibiae that are mostly brown, but only on the dorsal surface; the femora are yellow and the scutum is glossy.</p></div>	https://treatment.plazi.org/id/038B879BFF5E74FD12C0DBD64B38B7EB	Public Domain	No known copyright restrictions apply.

The record of Solidago multiradiata (Hansson 1987) is from a specimen of Chrysocharis viridis ( Eulophidae) labeled as having been reared from Nemorimyza posticata on this host, and it is unknown whether adult flies have been reared from this plant. Spencer (1969a) reported an unidentified agromyzid on Stachys palustris L. in Alberta, making an elongated brownish blotch adjoining the leaf margin; this now appears likely to represent N. posticata .</p><p>Leaf mine. (Fig. 194) A usually trumpet-shaped blotch with distinct feeding lines; see Eiseman &amp; Lonsdale (2018, including Figs.167–168). One mine on Solidago latissimifolia from which an adult was reared(iNat 94735588) was highly unusual, being essentially linear throughout. It superficially resembled a Liriomyza or Phytomyza mine, but had irregular margins and no clear frass pattern.A similarly linear mine found on S. ohioensis (iNat 134577744), with distinct secondary feeding lines, is also presumed to represent this species. Both of these mines are highly contorted at the beginning. Although larvae of Nemorimyza posticata are normally solitary, the mine on Rudbeckia laciniata, from which an adult was reared, contained three larvae that fed side by side. We have previously found up to three larvae feeding together in mines on Solidago patula, but only parasitoids were reared from these.</p><p>Puparium. Brown, formed outside the mine. Also see Guglya (2021, including Figs. 113–115).</p><p>Phenology and voltinism. This species is multivoltine. Larvae have been collected in mid-March (TX), late March (FL), late April (MO), early May (NC), mid-May (NC), early June (NC, NY), mid-June (MA, ME, NC), late June (IA, IL), early July (MA, MO, NC, WA), mid-July (IA, IL, MA, MI, NB, NC, WA), late July (NB, OH, WA), early August (MA, OH), mid-August (OK), late August (OK, TN), early September (IA, NB), and mid-October (FL), with adults emerging 20–34 days later (45 days for the Texas specimen, and 46–80 days for some Washington specimens collected as larvae in late July); larvae collected in mid-August (MA), late August (MA, NY, OH), mid-September (MA, MI), late September (MA), early October (MA), and mid-October (MA, OK) have overwintered as pupae and emerged as adults the following spring (Spencer &amp; Stegmaier 1973; Eiseman &amp; Lonsdale 2018; Priest et al. 2020).</p><p>Distribution.

Each of our collections of Riccia that produced adults of P. consulta also produced adults of P. imperfecta, which has a grayish velvety scutum that is only yellow laterally, and most of the acrostichal region tinted brownish. Phytoliriomyza consulta, in contrast, has a yellow scutum with brown bands, and if the dark bands are dominant, narrow yellow lines are still evident posteriorly along the dorsocentral and intra-alar rows. Phytoliriomyza imperfecta also has striping on the pleuron that is better defined and often larger and darker, the epandrium is yellow with one pair of brown dorsal spots (not entirely dark brown), and the epandrium and surstylus have rows of long thick setae (not sparse normal setae).</p></div>	https://treatment.plazi.org/id/038B879BFF4074E012C0DEE64BCEB348	Public Domain	No known copyright restrictions apply.

USA: CA, *CT, LA, *MA, MD, MI, *NC, PA, VA, WY; Canada: BC, MB, NT, ON, QC, YT; Europe; Russia; Iran; Japan (Lonsdale 2021).</p><p>Comments. The only previous records of liverwort-mining agromyzids in North America are those from Mexico given by Hering (1966) and repeated by Spencer (1990): a puparium found in a linear-blotch mine on Monoclea Hook. ( Monocleaceae), and mines on Dumortiera hirsuta (Sw.) Nees ( Dumortieraceae) that were either empty or contained a braconid cocoon. Our first indication of agromyzids occurring on liverworts in the USA was a photograph of an adult Phytoliriomyza, possibly dorsata, resting on a Conocephalum conicum s.l. thallus in Indiana, taken on 2 June 2020 (iNat 48355860). Then, in April 2022, JBV collected Marchantia polymorpha L. ( Marchantiaceae) thalli in Iowa with mines made mostly by sciarid larvae. On 11 April, an agromyzid larva appeared externally on the edge of a mined thallus that had been collected three days earlier, and it pupated within the next day (this ultimately proved to be P. pacifica (Melander)) . On learning of this observation on 13 April, CSE immediately set out in search of a thallose liverwort in Massachusetts, finally locating a single small patch of Conocephalum on a rock at the edge of a stream (on the same day, JBV discovered an empty Phytoliriomyza puparium projecting from a mined Conocephalum thallus in Iowa (BG 2109524)). No mines were evident on casual examination, but upon removing a piece (~ 3 cm by 3 cm) and holding it to the sun, two narrow linear mines could be seen, though they appeared to be empty. This sample was placed in a vial, and two days later an agromyzid larva appeared externally. This larva did not survive, but five adults of P. dorsata emerged a month later. On 17 May 2023, CSE placed a similarly small piece of Conocephalum from Connecticut —without evident mines—in a vial, and an adult emerged two weeks later. Based on these results, it appears that P. dorsata and other bryophyte-mining species must be far more common than the scattered adult collection records would suggest. In April 2024, TSF checked a Conocephalum population in North Carolina and found numerous adults of P. dorsata on the thalli.</p><p>Not long after we made our initial discoveries, Kato et al. (2022) reported rearing P. dorsata and 35 other Phytoliriomyza species from liverworts in Japan.Curiously, they reared P.dorsata only from Marchantia polymorpha, and their results indicated that all but one of the species they studied are monophagous, with 15 of them feeding on Conocephalum . They did not comment on the phenology of P. dorsata, but for most other species they noted that rearing records suggest a univoltine life cycle, with adults emerging from overwintered puparia in spring (not overwintering as larvae, as we have observed for both P. dorsata and P. pacifica).</p><p>Kato et al. (2022) noted that at least four North American species besides P. dorsata appear to belong to the bryophyte-feeding group of Phytoliriomyza: P. fumicosta (Malloch) (IL, KS), P. leechi Spencer (northern CA), P. pacifica (see below), and P. volatilis Spencer (CO, BC; Sweden) (distribution records from Spencer (1969a) and Spencer &amp; Steyskal (1986)). They predicted that P. pacifica may be a Conocephalum feeder based on its similarity to the Japanese species P. luna Kato. They did not mention P. conjunctimontis, P. consulta, or P. imperfecta, all of which have now been reared from hornworts and liverworts (see above and below).</p><p>Examination of the newly collected material has allowed us to build on the diagnoses developed by Lonsdale (2021) for Phytoliriomyza dorsata and P. pacifica . Little can be added to the external diagnoses, with the female P. dorsata from Connecticut having very faint brownish-orange supra-alar vittae, and some P. pacifica having paler legs, with the tibiae and tarsi all being occasionally faintly brownish (usually at least the hind tibiae and tarsi are brown). With regard to the male genitalia, the external components are more robust in P. dorsata, with 1–3 spines on the surstylus, which is larger, more rounded and swollen in appearance. This contrasts with the surstylus of P. pacifica, which has only one spine, and it is slightly smaller, flatter and directed inwards. Additionally, the comb of spines on the surstylus of P. dorsata appears to be slightly thicker and more tightly clustered (spines slightly narrower and apically diverging in P. pacifica), and there is a strong row of smaller, widely-spaced spines along the posterior margin of the epandrium around the anus (as opposed to being sparse to absent). The distiphallus of P. pacifica is more slender with the tubules of the distiphallus more divergent, and the hypophallus is weaker and Y-shaped (darker, longer and consisting of two narrow parallel bars in P. dorsata).</p><p>Three puparia are also now available for comparison—one for Phytoliriomyza dorsata and two for P. pacifica . The anterior and posterior spiracles for both are largely black with a short, wide subconical stem that is pale yellow like the remainder of the puparium. Regarding the anterior spiracles, P. dorsata differs in having the stem-like section narrow, long and clearly delimited from a small apical fan-like section (slightly wider than long, width half that of entire black structure) that bears the pores. In P. pacifica, the stem is relatively broad and appears very short since the apical section bearing the pores is elongate and oblique, nearly concealing the stem when viewed laterally. The posterior spiracle of both has a short stem bearing a subcircular plate with marginal pores. In P. dorsata, the plate is angled dorsally and the margin is relatively smooth, while in P. pacifica, the plate is transverse to the long axis of the spiracle and not angled, and the margin is irregular, being produced at the pores.</p></div>	https://treatment.plazi.org/id/038B879BFF4074E712C0DAB64CF8B0AB	Public Domain	No known copyright restrictions apply.

Spencer (1981) reported adults of this species collected from two fabaceous plants, Psorodendron spinosum (A.Gray) Rydb. (as Dalea spinosa) and Trifolium repens L. This is a good reminder that adult collection records of Agromyzidae should be treated only as clues to possible associations, and the plants on which adults are found should not be reported as “hosts.”</p></div>	https://treatment.plazi.org/id/038B879BFF4674E512C0D8B6489FB596	Public Domain	No known copyright restrictions apply.

(Spencer 1969a)], I. pallida Nutt., [ I. parviflora DC.]. The only previous North American rearing records for this species are those of I. capensis (as I. biflora) and I. pallida reported by Frost (1924, as Agromyza borealis Mall.).</p><p>Leaf mine. (Scheffer &amp; Lonsdale 2018: Fig. 3h; Guglya 2021: Fig. 284) Upper-surface, green to whitish; initially linear, with black frass in discrete grains along the sides; later broadly linear or forming a distinct blotch, with frass in scattered grains, irregular particles, and sometimes squiggly strips.</p><p>Puparium. Reddish-brown; formed outside the mine. Also see Guglya (2021, including Figs. 285–286).</p><p>Phenology and voltinism. Frost (1924) noted that leaf mines first appear in mid-June in New York and Pennsylvania, and host-feeding adults are abundant in early July, with mines becoming more abundant through the summer, and larvae being impossible to find toward the end of August. Based on this he believed there is a single generation per year. Scheffer &amp; Lonsdale (2018) observed larvae in New York only in June, and did not succeed in rearing adults. Our rearing records suggest there are at least two generations: larvae collected in late June in Iowa emerged as adults 21–22 days later, and a larva collected in Washington in early August emerged as an adult 42 days later; larvae that Eiseman &amp; Blyth (2022) collected in Massachusetts in late July overwintered as pupae and emerged as adults the following spring. Adults have been collected in Canada from mid-May (QC) to mid-September (ON), and in the USA from mid-May (MD) to late September (NY, PA) (Lonsdale 2021). Well-developed mines have been found as early as 2 April in Louisiana.</p><p>Distribution.

Inconspicuous; the collected plants were also mined by Scatopsciara ( Sciaridae) larvae, which were responsible for most, if not all, of the visible mines that prompted the collection. One puparium was found on the surface of a brown blotchy area at the edge of a thallus, which may have been the mine from which this larva emerged.</p><p>Puparium. (Fig. 76) Yellow; see last paragraph of Comments under P. dorsata . Of the three reared individuals, one mature larva emerged from a thallus within 72 hours after the plant material was brought indoors and kept at room temperature. It was found on the surface of what may have been its mine (see above). The larva was left undisturbed at this location and, within 15 hours, it formed its puparium there.

In Iowa, larvae overwinter, feeding until mid-April, then pupate, and emerge as adults in late April and early May. For the single individual for which the time of pupation was noted, the pupal stage lasted 17 days.

Additionally, the palps are grayish-brown, the orbits and deeper yellow frontal vitta are devoid of brown pigment, and the femora are entirely yellow (not brown mottled) with the apices very faintly orange-brown tinted.

Basiphallus halves joined dorsally near base, with pointed left ventral arm wrapping around venter of shaft; right sclerite broader apically with end truncated, inner distal margin with seven well-developed spines; left sclerite shorter, margins irregular, apically pointed, dorsum lined with dozens of spines that become smaller towards point of fusion with other half of basiphallus; basiphallus distant from distal components of phallus. Hypophallus U-shaped, narrowest at weakly sclerotized midpoint; dark, ventrally curved with angled points on both sides before middle; left base appears to be lengthened, but this extended section is a separate fused portion of the left sclerite of the basiphallus. Paraphalli membranous, extending from ventromedial point on mesophallus to bases of hypophallus. Mesophallus subcylindrical, base rounded, fused apically to two tubules of distiphallus that are similarly clear and nearly as wide, appearing as a single Y-shaped structure; angled dorsally, nearly leaning backwards over surface of basiphallus; distiphallus tubules about half length of mesophallus. Ejaculatory apodeme small, sperm pump with one pair of rounded sclerites.</p><p>Comments. Phytomyza antennariae belongs to the P. albiceps group, which is characterized by a distinct phallus that often bears numerous spines. This species does not key readily in Spencer &amp; Steyskal (1986) due to intraspecific variability with respect to the number and size of fronto-orbital setae, and due to ambiguities in the key, but a series of revisions by Griffiths (1974a, 1974b, 1976) examines most of the known north temperate species. While a number of the species illustrated by Griffiths have a similar fused and entirely clear mesophallus and distiphallus, very few also have spines along both the left and right sclerites of the basiphallus, and none show either heavy clusters of spines, or an apically thickened basiphallus that has a separate portion fused to the left base of an unusually angled hypophallus. This combination of characters readily differentiates it from others in the group.</p><p>The European Phytomyza kyffhusana Hering is also known from this host genus, but the phallus past the phallophorus is a single linear sclerite with the distal surface minutely spined. It also has a single ors and an entirely yellow orbital plate.</p></div>	https://treatment.plazi.org/id/038B879BFF4974E812C0DEE64917B527	Public Domain	No known copyright restrictions apply.

(Eiseman &amp; Lonsdale 2018), * Thalictrum dasycarpum Fisch., C. A.Mey. &amp; Avé-Lall., T. pubescens Pursh. Frost’s (1930) original description only mentions the holotype reared from A. vulgaris, but among the paratypes at the USNM are two females reared from “meadow rue” (Lonsdale 2021), the common name for Thalictrum spp. Frick (1959) gave both Aquilegia spp. (including A. formosa var. truncata (Fisch. &amp; C.A.Mey.) Baker) and Thalictrum spp. (including T. fendleri Engelm. ex A.Gray and T. pubescens Pursh) as hosts. Spencer (1969a) and Spencer &amp; Steyskal (1986) listed only Aquilegia spp. as hosts (the latter authors noting that Frick’s specimens from the western USA were misidentified, but T. pubescens is an eastern species). Spencer (1990) listed P. aquilegiana among the species feeding on Aquilegia and Ranunculus, the latter apparently by accident, since this host record is not mentioned in the text of that or any previous publication. Benavent-Corai et al. (2005) listed P. aquilegiana among the Thalictrum feeders and not among the Ranunculus feeders, also apparently by accident, since on p. 36 they listed Aquilegia and Ranunculus as the hosts of P. aquilegiana, and they cited no reference other than Spencer (1990) for any of these records. Thus, our specimens do not exactly represent the first records of this species from Thalictrum, but confirm prior records that were at least partly erroneous.</p><p>Leaf mine. (Fig. 198) An upper-surface primary blotch, with frass in scattered, fine, black grains. On Aquilegia, the mine is initially interparenchymal, appearing green from above; later a patch of reddish discoloration develops, and the larva feeds closer to the upper surface, so that the rest of the mine has a mixture of whitish and green patches. The mines we observed on Thalictrum were whitish with extenstive brownish staining, no reddish discoloration, and little or no green/interparenchymal area (two photographed mines have none at all, and one has a single, very small patch).</p><p>Puparium. Reddish-brown, deeply segmented; formed outside the mine.</p><p>Phenology and voltinism. Larvae have been collected in late May (MA, NC, NY), late June (IA), and mid-July (ON), with adults emerging 16–25 days later; larvae collected in early July (NS), mid-July (AB), and mid-August (YT) have overwintered as pupae, emerging as adults the following spring (Spencer 1969a; Sehgal 1971; Eiseman &amp; Lonsdale 2018; Scheffer &amp; Lonsdale 2018). Reared California specimens have dates of 13 January and 19 October (Lonsdale 2021).</p><p>Distribution. USA: CA, MA, MD, ME, NC, NY, PA, VA; Canada: AB, BC, MB, ON, YT (Lonsdale 2021). Frick (1959) also reported specimens from ID and WA, but according to Spencer &amp; Steyskal (1986) these represent P. aquilegioides Sehgal.</p><p>Comments. Two other species in the Phytomyza aquilegiae group— P. aquilegioides Sehgal (AK, AB, CA) and P. columbinae Sehgal (AB, CA, WY) —are known to form blotch mines on Aquilegia spp. in North America, and P. sonorensis Spencer (CA) probably does as well since it belongs to the same group. Based on existing records, it would appear that such mines found east of Alberta and Wyoming can be safely attributed to P. aquilegiana . The eastern species P. plumiseta Frost, P. dasycarpi sp. nov., and P. dioici sp. nov. form blotch mines on Thalictrum (as do P. aquilegioides and P. columbinae), and more rearing is needed to determine whether there are consistent differences among the mines of these species.</p></div>	https://treatment.plazi.org/id/038B879BFF4874EF12C0DC1B4AF6B623	Public Domain	No known copyright restrictions apply.

Apiaceae: Cicuta douglasii (DC.) J.M.Coult. &amp; Rose, C. maculata L.</p><p>Leaf mine. (Fig. 201) Upper-surface (though at least sometimes starting on the lower surface), whitish, entirely linear; frass in black grains that are mostly well separated, occasionally forming short beaded strips.</p><p>Puparium. Dark brown, barrel-shaped with sides bulging, slightly compressed laterally; formed outside the mine.</p><p>Phenology and voltinism. Larvae collected in mid-June in Alberta and Michigan emerged as adults 12–23 days later. Those collected in late August in Alberta overwintered as pupae and emerged as adults the following spring.</p><p>Distribution. USA: MI; Canada: AB.</p><p>Adult description. Wing length approximately 2.0– 2.3 mm (♂), 2.1–2.5 mm (♀). Vein dm-m absent. Eye height divided by gena height: 3.1–4.4. Ocellar triangle rounded, slightly larger than tubercle. Body subshining, with pruinosity on notum slightly thicker and brownish-gray in color.</p><p>Chaetotaxy: Two ori, with posterior ori slightly shorter than anterior ors, and anterior ori thinner with length setula-like or as large as ⅖ length of posterior ori; two ors, with posterior ors absent to ⅔ length of anterior ors, but uncommonly as large. Postvertical and ocellar setae well-developed. Four dorsocentral setae, decreasing in length anteriorly, with fourth seta ⅖–½ length of first. Four irregular rows of acrostichal setulae, tapering to two rows (less commonly three) and ending at level of first dorsocentral.</p><p>Coloration: Setae dark brown. Head base color light brown to tan; first flagellomere, back of head, ocellar triangle (confluent with margin of vertex), clypeus and palpus dark brown; pedicel and scape brownish-orange; orbital plate brown, appearing faintly iridescent in some light due to thin layer of pruinosity; ventral margin of gena with brownish-orange line. Thorax dark brown with very narrow yellow line dorsally on anepisternum, and with slightly paler brown halo around anterior spiracle; paler brown mottling on postpronotum and notopleuron. Wing veins light brown. Calypter yellow, hairs light brown. Legs mostly dark brown; apex of fore femur light yellow for length sometimes equal to width of femur apex; if fore femur more extensively pale, then apices of mid and hind femora also narrowly pale, but if fore femur with shorter pale spot, then apices of mid and hind femora very narrowly yellow or entirely dark; bases of tibiae yellowish to light yellow, with fore leg most frequently paler and hind leg darker; tarsi paler brown. Abdomen dark brown.</p><p>Genitalia: (Figs. 439–444) Epandrium not fused to small, rounded surstylus. Cercus short but well-developed. Hypandrium not much longer than wide, subtriangular with apex broadly rounded; inner lobe small with two setae in sclerotized section and one additional seta in membranous medial surface. Postgonite relatively short and thick with one seta; distal margin with long inner ridge, and inner lobe very short and broadly rounded. Phallophorus very short; dorsal margin weakly connected to dorsal base of right sclerite of basiphallus. Basiphallus made of two long, narrow dark sclerites, with base of right side broader and positioned dorsally, and base of left side twisting around shaft ventrally; apices of basiphallus adjoining paraphallus and hypophallus. Hypophallus sclerite dark, U-shaped; distomedial margin on each side with raised membranous surface bearing long, narrow, floating and minutely spinulose sclerite. Paraphallus mostly membranous, band-like, and with short, dark triangular sclerotized section at point of insertion on mesophallus. Mesophallus short and sac-like with base broadly rounded, appearing almost spherical in ventral view; with irregular patches of sclerotization ventromedially where paraphalli insert and on ventroapical margin of ejaculatory duct; one additional pair of small sclerotized blotches dorsolaterally. Distiphallus mostly clear, not much longer than mesophallus, consisting of one pair of fused tubules that flare apically; point of fusion to mesophallus not detectable; each tubule with subapical sclerotized ring that narrowly extends along inner-ventral margin. Ejaculatory apodeme small, sperm pump with one pair of faint, narrow pigmented spots.</p><p>Comments. This is the second North American record of a Phytomyza species from Cicuta, after P. cicutella, which makes entirely different leaf mines (see above). However, the Holarctic species P. pastinacae Hendel (AB, NY) has been reared from C. virosa L. in Lithuania (Pakalniškis 2000), and its mines are probably not distinguishable from those of P. cicutiphaga . Linear Phytomyza mines have been found on C. maculata in Ontario (iNat 50096513, 50368437, 82354581, 292196981), New Brunswick (iNat 51611975), Minnesota (iNat 183892412), Massachusetts (iNat 195844839), Illinois (iNat 32423995, 53288669, 53008195), and Ohio (iNat 180559710), with the shining blackish puparia sometimes loosely adhering to the upper leaf surface. A few occupied mines were found in early September in Illinois. Similar mines have also been found on C. douglasii in Alaska (iNat 122921773, 180228539; larvae present in June) and Oregon (iNat 182463433), and on Cicuta sp. in Manitoba (iNat 131104829).</p><p>Existing adult keys cannot be easily modified to accommodate this species due to the variability inherent in the fronto-orbital setae and leg coloration. Externally, Phytomyza cicutiphaga differs from most congeners with an almost entirely dark thorax, brownish calypter hairs and four rows of acrostichal setulae in having a mostly brownish/tan head with the orbital plate brown, the first flagellomere dark brown and the scape and pedicel are light brown. The anterior ori and the posterior ors are also usually shorter to absent or indiscernible, and the fore knee is distinctly yellow while the mid and hind knees are more narrowly yellow to entirely dark.</p><p>Examination of the genitalia is required for confident diagnosis. Phallic morphology immediately associates this species with Phytomyza ziziae Eiseman &amp; Lonsdale, as this species also has both the basiphallus and hypophallus simple, dark and narrow, and the hypophallus has a raised membrane supporting a long sclerotized patch with a minutely spinulose surface. In P. ziziae, however, the basiphallus is slightly shorter and more fully fused to the paraphallus, the paraphalli are faintly pigmented with a much narrower terminal sclerotized patch where it meets the mesophallus, the mesophallus is smaller with no dark dorsal patches and it has one pair of lobate membranous extensions ventrally, and the distiphallus is narrower, longer and differently pigmented subapically. Additionally, there are only two to three rows of acrostichal setulae, the orbital plate is slightly less pigmented and the anterolateral region of the notum is paler. Phytomyza hatfieldae Eiseman &amp; Lonsdale is also clearly related with a similarly shaped mesophallus and distiphallus, but the basiphallus is minutely spinulose dorsobasally, the hypophallus is irregular apically and the raised sclerotized margin is longer and more clearly spinulose, the paraphallus has a longer, narrower sclerotized patch where it meets the mesophallus, the mesophallus is dorsally unpigmented, the first flagellomere is slightly enlarged and the head is darker brown.</p></div>	https://treatment.plazi.org/id/038B879BFF4E74EC12C0D8B74BE9B463	Public Domain	No known copyright restrictions apply.

An upper-surface blotch, similar to the mine of Phytomyza plumiseta; the Michigan specimen emerged from a collection of mines that also yielded several adults of that species. The occupied mines photographed in Michigan were all still small and were whitish with a central green patch that was associated with a leaf vein, but it is possible that these were all P. plumiseta mines. The leaves photographed in association with the Iowa rearing (MJ Hatfield, in litt.; BG 2502781, 2502785) show one early mine and three that are completed or nearly so, none of which has a central green patch.

First flagellomere small, rounded, slightly longer than high; hairs along distal margin slightly longer. Ocellar triangle larger than tubercle, ovate. Cheek narrow. Thorax with faint brownish pruinosity that is denser on notum; female pruinosity slightly denser and with additional bluish tint when viewed at certain angles.</p><p>Chaetotaxy: Two ori, two ors, with setae decreasing in length anteriorly; anterior ori sometimes as small as half length of posterior ori. Ocellar and postvertical setae well-developed. Four dorsocentral setae, decreasing in length anteriorly (fourth seta about ⅗ length of first). Five irregular rows of acrostichal setulae, tapering posteriorly, almost reaching level of first dorsocentral.

Thorax mostly brown; notum light brown laterally anterior to wing base, with paler stripe narrowed behind transverse suture; dorsal margin of anepisternum narrowly yellowish-white, with stripe tapering anteriorly. Wing veins yellow. Calypter yellowish-white with hairs light brown with yellowish shine. Legs paler brown than thorax; apex of fore femur yellow for distance almost equal to width of femur apex; yellow apical spot on mid and hind femora shorter than spot seen on fore femur; tibiae paler than femora, sometimes light brown, with fore tibia brownish-yellow excluding darker region dorsomedially; mid tibia yellowish at base and apex; tarsi yellowish. Abdomen dark brown with lateral and posterior margins of tergites narrowly light yellow.</p><p>Genitalia: (Figs. 445–451) Epandrium fused to small, rounded surstylus that is ill-defined anteriorly. Cercus narrow. Hypandrium subtriangular with rounded apex; inner lobe short with two or three apical setae. Postgonite well-developed with one seta. Phallophorus subcylindrical, slightly constricted medially, not fused to basiphallus; flanked by one pair of high, flat lobes that are thicker along distal and anterior margins. Basiphallus consisting of two long sclerites that are narrowly and weakly fused subbasally, and flared and irregularly sclerotized apically; left sclerite with very long arm wrapping around venter of shaft that is very weakly and irregularly sclerotized along most of length; right sclerite with base broader, flatter and dorsal in position, adjoining dorsal margin of phallophorus. Hypophallus large and membranous with one pair of dark lateral sclerites that are about three times longer than high with anterobasal margin irregularly sclerotized; paired sclerites converging distally towards, and weakly fused to weaker ventromedial sclerite that is narrow and bifurcated dorsally, and broader, plate-like and bifurcated ventrally. Paraphalli similar in appearance to lateral hypophallus sclerites, converging distally to point of fusion ventromedially on mesophallus. Mesophallus subcylindrical, rounded at ends, with deep desclerotized notch on laterodistal margin, and about 3.5 times longer than wide with slight medial constriction; with raised ventromedial ridge that widens to meet apically pigmented ejaculatory duct; ventrodistal margin with narrow extension fused to distiphallus; dorsal surface with small flat sclerite on surface past midpoint. Distiphallus about as long as mesophallus, divided into one pair of narrow diverging tubules that are ill-defined distally along inner surface, and are darker and thicker ventrally on basal half. Ejaculatory apodeme with exceptionally large, rounded blade with clear distal margin, and with small stem and base; sperm pump small with strong transverse ventral sclerite that is darker and upturned at ends.</p><p>Comments. Although this species is so far only known to feed on Thalictrum dasycarpum, mines on this plant should not be assumed to represent Phytomyza dasycarpi, since P. aquilegiana and P. plumiseta have also been reared from blotch mines on the same host. The P. dasycarpi holotype, in fact, emerged from a collection of mines that produced six males and six females of P. plumiseta in July 2019, plus another female that emerged the following spring, six days before the P. dasycarpi male. We have assigned this female to P. plumiseta because, compared with the P. dasycarpi male and the two females from Iowa, it is slightly larger (wing length 3.0 mm) and paler, with the anterolateral region of the notum whitish-yellow, approximate posterodorsal third of anepisternum light brown to whitish, dorsal margin of katepisternum and meron whitish, anepimeron, anatergite and katatergite with whitish mottling, and gena, palpus and clypeus paler brown. These features are all consistent with P. plumiseta .</p><p>Also see Comments for Phytomyza dioici .</p></div>	https://treatment.plazi.org/id/038B879BFF7374D212C0DA464AF0B183	Public Domain	No known copyright restrictions apply.

Saxifragaceae: Micranthes *careyana (A.Gray) Small, M. ferruginea (Graham) Brouillet &amp; Gornall, [ M. hieraciifolia (Waldst. &amp; Kit. ex Willd.) Haw., M. lyallii (Engl.) Small, M. nelsoniana (D.Don) Small (as Saxifraga punctata L.), M. nivalis (L.) Small, M. virginiensis (Michx.) Small] (Griffiths 1972).</p><p>Leaf mine. Griffiths (1972) described the mine as beginning with a short linear channel, but soon broadening into an irregular blotch that sometimes encloses the initial linear channel, and ending with a short channel on the lower surface leading to the pupation site; a few mines formed entirely on the lower surface were also found. The mines on Micranthes careyana (iNat 152989658, 152990266) appear to be essentially linear throughout, though sometimes contorted to form a secondary blotch. They are whitish with varying amounts of reddish discoloration, with black frass in fine grains as well as large, irregular particles and occasionally squiggly strips.</p><p>Puparium. White, brown, or blackish; formed within the leaf, on the lower or (observed in this study)occasionally the upper surface, with its anterior spiracles projecting ventrally through the epidermis (Griffiths 1972).</p><p>Phenology and voltinism. Mines collected in late March in Tennessee yielded adults from 7 to 11 April; the photographed mines do not appear fresh and the puparia presumably had overwintered. In Alaska, larvae and puparia have been collected in mid-August, with some adults emerging 13–14 days later and others the following spring (Griffiths 1972).</p><p>Distribution. USA: AK, [GA, NY], *TN, [VT; Canada: AB, BC]; Japan (Griffiths 1972).</p><p>Comments. The only other North American agromyzid known to feed on Micranthes is Phytomyza palustris Eiseman &amp; Lonsdale; the entire type series was reared from a single individual of M. pensylvanica (L.) Haw. in Massachusetts, and no further specimens are known, although Phytomyza mines have been found on this host in Ontario (iNat 310652858) and Minnesota (iNat 248377523, 248377593, 271201872, 309855097). The leaf blades of M. pensylvanica are up to 25 cm long, and we believe that there is not sufficient space for the rather long mines of P. palustris in the much smaller leaves of M. virginiensis on which mines were found in Vermont. Phytomyza mines have also been found on M. caroliniana (A.Gray) Small in North Carolina (iNat 55237929); M. mertensiana (Bong.) Rosend. in Alaska (iNat 168737348, 173146048), British Columbia (iNat 187034857), Washington (iNat 28450339), and Oregon (iNat 162890959, 162891154); M. micranthidifolia (Haw.) Small in North Carolina (iNat 84433561, 168614788) and Pennsylvania (iNat 27163368); M. odontoloma (Piper) A.Heller in Oregon (iNat 298807905); and M. petiolaris (Raf.) Bush in North Carolina (iNat 53248836, 58496769, 58496786, 93170539, 184857186) and Tennessee (iNat 182127851). We suspect that these mostly represent P. deirdreae, but we hope that adults can be reared from each of these hosts to confirm, as well as from the additional hosts on which Griffiths found mines in western Canada and Alaska.</p></div>	https://treatment.plazi.org/id/038B879BFF7174D012C0DDFB4AEDB6EF	Public Domain	No known copyright restrictions apply.

(Figs. 202, 203) A whitish, upper-surface blotch. As in Phytomyza plumiseta, there is at least initially a small, green patch of uneaten palisade mesophyll beneath which much of the frass is deposited. The fine, blackish, irregular frass particles are scattered more diffusely around this dense central deposit. Each of the three photographed mines contained two larvae.</p><p>Puparium. (Fig. 83) Reddish-brown, deeply segmented; formed outside the mine.</p><p>Phenology and voltinism. Larvae collected in late June in Iowa yielded some adults three weeks later and others the following spring.</p><p>Distribution. USA: IA.</p><p>Adult description. (Figs. 84, 85) Wing length approximately 2.1–2.3 mm (♂), 2.4–2.5 mm (♀). Vein dm-m absent. Eye height divided by gena height: 5.3–6.0. First flagellomere small, rounded, slightly tapered apically; hairs on distal margin slightly longer and denser. Ocellar triangle slightly larger than tubercle, approximately equilateral with corners broadly rounded. Cheek narrow. Thorax subshining with pruinosity brownish; notum pruinosity denser with faint bluish tint.</p><p>Chaetotaxy: Three ori, decreasing in length anteriorly, with anterior seta thinner and sometimes setula-like to absent; two ors, with posterior ors sometimes ⅘ length of anterior ors and sometimes absent from one side. Ocellar and postvertical setae well-developed. Four dorsocentral setae, decreasing in length anteriorly with fourth seta half length of first. Five irregular rows of acrostichal setulae ending between level of first and second dorsocentrals.</p><p>Coloration: Setae dark brown with paler shine. Head mostly light yellow; antenna, ocellar triangle, posterolateral corner of frons to base of inner vertical seta, back of head, clypeus, outer surface of palpus and ventral line on gena brown; paler spot at base of outer vertical reaching eye; small, narrow brown stripe along eye reaching level of posterior ors; remaining posterior margin of frons light brown. Thorax mostly brown; lateral margin of notum with paler brown mottling, and scutum with one pair of small, faint yellowish spots anteriorly; dorsal margin of anepisternum narrowly whitish, with line tapering anteriorly. Wing veins yellow. Calypter yellowish-white, hairs brown. Legs paler brown in base color with tibiae and tarsi more yellowish; apex of fore femur light yellow for distance less than width; fore tibia yellow with faint brown tint dorsomedially; mid and hind tibiae yellowish at base and apex. Abdomen brown with lateral and posterior margins narrowly whitish.</p><p>Genitalia: (Figs. 452–457) Epandrium fused to small, rounded surstylus that is ill-defined posteriorly. Cercus narrow. Hypandrium subtriangular with apex narrower and rounded; inner lobe with two setae. Postgonite well-developed with one seta. Phallophorus subcylindrical, shallow, weakly fused to right sclerite of basiphallus dorsally; flanked by one pair of broad, rounded, pale lobes that are thicker anterobasally. Basiphallus with two sclerites that are weakly and narrowly fused subbasally; right sclerite broader and flatter at base, which is positioned dorsally; left sclerite with long, well-defined arm wrapping around venter of shaft; apices with narrow, irregularly sclerotized extension fused to base of paraphalli. Hypophallus membranous with one pair of narrow, pale lateral sclerites; sclerites converging to weak, pale medial sclerite that is narrow and bifurcated basally, and broader and flattened ventrally. Paraphalli small, globose, narrowed to medial point of fusion on ventromedial surface of mesophallus. Mesophallus subcylindrical with rounded ends, distolateral margins with desclerotized notch, length more than four times width, dorsoventrally compressed on basal ⅔; with shallow, irregular ventromedial carina separate from small ventrobasal process that meets apex of ejaculatory duct; with very narrow distal processes fused to base of distiphallus; very small, flat sclerite lying on dorsomedial surface. Distiphallus divided into one pair of dark, slightly diverging tubules that are weakly joined at base, ill-defined distally along medial surface, desclerotized dorsobasally and thicker and darker ventrobasally. Ejaculatory apodeme not recovered.</p><p>Comments. As discussed under Phytomyza aquilegiana, multiple species form similar blotch mines on Thalictrum . So far, P. dioici is the only species known to feed on T. dioicum, and it may be that this plant is not used by P. aquilegiana or P. plumiseta since we have never seen mines on it in New England where both species are common, but more rearing is certainly needed. Blotch mines have been photographed on T. dioicum in Ontario (iNat 131791595, 172420171), Minnesota (iNat 82503395), Wisconsin (iNat 172063978, 182013137), Illinois (iNat 89799482), New York (iNat 137524966), and North Carolina (iNat 81845400, 86074659).</p><p>Phytomyza dasycarpi and P. dioici are closely related, as supported by a number of adult characters including a mostly dark body with brownish pruinescence that may also appear bluish on the notum, paler shoulders, a pale head with a dark antenna, a slightly tapering first flagellomere, a larger ocellar triangle, a light brown stripe along the vertex, brownish to brown calypter hairs on a yellow margin, paler tibiae and tarsi, five irregular rows of acrostichal setulae, and characteristic male genitalia that also associate them with P. aquilegiana and P. plumiseta .</p><p>External characters provide slight differences in dimensions and coloration that allow for differentiation, but with intraspecific variation already apparent among the few specimens known, these differences may prove to overlap enough to confuse diagnoses. As such, genitalia should be examined for confident diagnosis. Until then, however, Phytomyza dioici appears to regularly have a pale spot around the base of the outer vertical, there is sometimes a third pair of ori present, the paler markings on the notum extend to the posterior margin of the scutum, the gena is slightly higher (the eye is 5.3–6.0 times higher) and only the fore femur is narrowly yellow ( P. dasycarpi yellow on all knees with spot narrow on mid and hind legs). With regards to the genitalia of P. dioici, the hypophallus sclerites are narrower and pale and the paraphallus is smaller and globose, the paraphallus and basiphallus are weakly connected (separate in P. dasycarpi with basiphallus apices broad and irregular), the ventral branch of the left basiphallus sclerite is broad and strong (long, but irregular and atrophied in P. dasycarpi), the mesophallus is slightly longer than the distiphallus and flattened along most of its length and the distiphallus is straight (slightly curved ventrally in P. dasycarpi).</p></div>	https://treatment.plazi.org/id/038B879BFF7074D712C0DC534A62B26B	Public Domain	No known copyright restrictions apply.

(Lonsdale &amp; Scheffer 2011: Fig. 5; Scheffer et al. 2021: Fig. 4; Sharrow et al. 2024: Fig. 1) According to Kulp (1968), the first instar forms a small blotch mine on the lower leaf surface and the second and third instars form a serpentine-blotch mine on the upper surface. According to Scheffer et al. (2021), mines produced in spring (or on fresh new leaves) are predominantly linear, and those produced in the fall in older, tougher leaves are “black blotches (formed by very tight twisting).”</p><p>Puparium. Brownish-yellow (Lonsdale &amp; Scheffer 2011), formed within the leaf, with the anterior spiracles usually projecting through the upper epidermis but occasionally through the lower epidermis (Kulp 1968).</p><p>Phenology and voltinism. Kulp (1968) reported a univoltine life cycle in Washington, DC, with pupae overwintering, adults emerging and ovipositing in mid-May, first instars present from June to August, third instars becoming numerous in October, and puparia appearing in late October. According to Lonsdale &amp; Scheffer (2011), this species is multivoltine, with one or more generations in both the spring and the fall. Our Oklahoma specimens emerged in late May from leaves collected in late April (at which time the mines were not noticed), and in Arkansas mines containing larvae have been photographed in early March and mines containing puparia in early April, so clearly there is more than one generation at least in the southern part of P. ditmani ’s range. The observation of well-developed upper-surface mines in Texas on 13 March, containing larvae and a puparium “a mere ten days after the leaf buds broke”, with an adult emerging on 23 March (BG 1787709), is very much at odds with Kulp’s account. Mines containing a larva and puparium have been photographed as early as 9 March in Louisiana.</p><p>Distribution. USA: AR (Sharrow et al. 2024), DC, [GA, LA], MD (Scheffer et al. 2021), ME, MI, [MO, MS], NC, *OK, PA, [TX] (Lonsdale &amp; Scheffer 2011). Scheffer et al. (2021, p. 63) reported new state records of MD and VA, but the latter is not supported by the cited supplementary table.</p><p>Comments. The photographed mines were all identified based on the assumption that this is the only agromyzid mining leaves of Ilex decidua . We know of no reliable way (apart from DNA sequencing) to distinguish mines of Phytomyza ditmani from those of related species that also feed on I. montana and I. verticillata .</p></div>	https://treatment.plazi.org/id/038B879BFF7774D612C0DBD74CA9B335	Public Domain	No known copyright restrictions apply.

(Fig. 205) The mines we observed on Erigeron pulchellus were long, whitish, entirely linear, upper-surface mines with black frass mostly in beaded strips along the sides. Griffiths (1976) described the mine as “basically linear, 3-5 cm long, 1.5-2 mm wide terminally, but in some cases (especially in smaller leaves) with secondarily blotchy areas; faeces deposited as fine particles, partly forming short beaded strips”; he reported that a few mines were partly on the lower surface, and that the semicircular exit slit was in most cases on the upper surface. A series that he suspected represented a distinct subspecies was reared from mines that “were linear throughout and significantly longer (8-10 cm) than those from other areas.” We believe the mines we photographed were at least 10 cm long, and this also appears to be the case for the one illustrated by Scheffer &amp; Lonsdale (2018: Fig. 4d).</p><p>Puparium.

We suspect there is no way to distinguish between mines of Phytomyza erigeronis and P.erigerophila, which are now both known to have broad ranges in the USA that extend at least from New England and North Carolina to the Midwest (as well as Alberta for P. erigerophila). It is probable that the mines of P. peregrini Griffiths, currently known only from Alberta where it was reared from E. glacialis (Nutt.) A.Nelson (as E. peregrinus (Pursh) ssp. callianthemus (Greene); Griffiths 1976), are also indistinguishable.</p></div>	https://treatment.plazi.org/id/038B879BFF7674D512C0D9764BD4B49B	Public Domain	No known copyright restrictions apply.

Hydrophyllaceae: Hydrophyllum *appendiculatum Michx., [ H. macrophyllum Nutt.], H. virginianum L. (Eiseman &amp; Lonsdale 2018). After revisiting the Hydrophyllum population at the type locality in Ohio, we are convinced that the host of the holotype was H. appendiculatum rather than H. canadense L. as reported by Eiseman &amp; Lonsdale (2018), and this may also be the case for the Tennessee paratype. Mines likely representing P. hydrophyllivora have, however, been found on true H. canadense (see Comments). The other widespread eastern Hydrophyllum, H. macrophyllum, is abundant at the type locality, but mines are rare on this host.</p><p>Leaf mine. (Fig. 206) Upper surface; greenish to pale brown; initially narrow and linear, expanding to a blotch that occupies most or all of a Hydrophyllum virginianum leaf segment. Distinct concentric feeding lines are sometimes present. Black frass is scattered throughout in small grains and irregular lumps, or sometimes in squiggly strips. On H. appendiculatum, the larva cuts a crescent-shaped exit slit in the lower epidermis (Eiseman &amp; Lonsdale 2018). Up to four larvae may complete development in a single H. appendiculatum leaf.</p><p>Puparium. Yellow to yellowish-brown, brown, or rarely reddish; formed entirely within the mine (on the lower surface), partly protruding from the exit slit, or entirely outside the mine (Eiseman &amp; Lonsdale 2018).</p><p>Phenology and voltinism. This species is apparently multivoltine. Larvae have been collected in late June (IA), early August (OH) and late August (TN), with adults emerging 20–30 days later; some puparia from the June collection, as well as one collected in mid-September (MA), overwintered and yielded adults the following spring (Eiseman &amp; Lonsdale 2018).</p><p>Distribution.

(Fig. 207) Whitish, linear, upper-surface; beginning with a small spiral or contorted portion that at least sometimes is initially on the lower surface; frass in fine, closely spaced, black grains, sometimes forming beaded strips along the sides and sometimes more scattered. The larva exits through a slit on the lower leaf surface (Eiseman &amp; Lonsdale 2018).

This species is evidently multivoltine. Larvae and puparia have been collected in early May (CA), mid-June (CT, MI, NC), late June (IA, MA, MI, MN), early July (MA, ON), and early August (NC), with adults emerging 14–31 days later (Spencer 1981; Spencer &amp; Steyskal 1986; Eiseman &amp; Lonsdale 2018); a larva collected in late September (MI) overwintered as a pupa and emerged as an adult the following spring (Priest et al. 2020), as did a puparium collected in mid-October (CT).</p><p>Distribution.

Following the recent synonymy of Phytomyza ranunculoides with P. loewii (Lonsdale 2021), P. loewii is one of two North American agromyzids known to form linear leaf mines on Ranunculus . The spiral or contorted area at the beginning distinguishes its mines from those of P. ranunculi (Schrank), as well as from those of polyphagous Liriomyza spp. that might occasionally occur on this host, which would also differ in having frass in strips instead of discrete grains. Several other species form linear leaf mines on Clematis . Phytomyza clematiphaga Spencer (AB, CO, MD, MT) differs in that its puparium is formed within the mine, it deposits frass in continuous or beaded strips, and it has not been observed to form a spiral or contorted area at the beginning (Eiseman &amp; Lonsdale 2018; Lonsdale 2021). The remaining species are only known from western states and provinces. Phytomyza clematoides Spencer is known from Washington, with a tentatively identified female from Colorado, in both cases on C. ligusticifolia; the Colorado mines, at least, were not contorted at the beginning (Eiseman &amp; Lonsdale 2018). An empty mine found on C. vitalba L. in Oregon (iNat 164330437) is consistent with P. loewii but might possibly represent P. clematoides . Phytomyza pulsatillae Hering is known from Yukon and Alberta (Boucher &amp; Wheeler 2001); it has been reported from C. alpina in Europe, and its mine begins with a small, compact spiral on the lower leaf surface; the otherwise upper-surface mine is said to turn blackish-brown, with frass in beaded strips, and with the exit slit in the upper epidermis; the puparium is yellow (Ellis 2024). Phytomyza clemativora Coquillett was reared from an undetermined Clematis, “presumably from leaf mines,” in southern Texas, but no details of the larval habits were recorded (Spencer &amp; Steyskal 1986); Spencer &amp; Steyskal (1986) placed this species in Chromatomyia Hardy, but Winkler et al. (2009) placed it in the P. loewii group, noting that it is related to P. clematoides (which Spencer (1990) placed in Chromatomyia), and asserting that neither species pupates internally, but it is unclear what evidence this was based on since there seem to have been no further rearings of P. clemativora . Mines consistent with P. loewii, but possibly representing P. clemativora, have been found in southern Texas on C. drummondii Torr. &amp; A.Gray (iNat 69356570, 69356571).</p></div>	https://treatment.plazi.org/id/038B879BFF7B74D912C0D89B4A22B33E	Public Domain	No known copyright restrictions apply.

(Fig. 208) Upper-surface, pale green to whitish, entirely linear. On Mitella nuda, Griffiths (1972) reported that the frass is “deposited as fine particles, forming more or less continuous strip in early part of mine, separated (but mostly by less than 1 mm) in terminal part of mine.” On M. diphylla, the black frass is typically in very widely spaced black grains, but we have observed considerable variation; in one mine, frass was almost entirely absent; some mines had short beaded strips in the early portion; and rarely frass was in closely spaced grains throughout, partly forming short beaded strips, and with some squiggly strips in the later portion.</p><p>Puparium. (Fig. 86) Griffiths (1972) stated that the puparium is uniformly brown or yellow-brown. In our experience it is typically whitish with black, transverse ventral stripes, which become confluent posteriorly, where they form a continuous band; some are brown with less conspicuous markings, and one was almost uniformly pale brown. Possibly overwintering puparia (which were all that Griffiths observed) have a tendency to be darker with faint to obsolete markings. The puparium is formed within the leaf, in a small blotch/blister on the lower surface, with its anterior spiracles projecting ventrally through the lower epidermis.</p><p>Phenology and voltinism. This species appears to have at least three generations per year, at least in the USA. Larvae and puparia have been collected in mid-June (CT), late June (IA), and mid-August (MA), with adults emerging 3–11 days later. Larvae and puparia collected in Alberta from late August to late September yielded adults the following spring (Griffiths 1972).</p><p>Distribution. * USA: CT, IA, [IL], MA, [MD, MN, NC, NY, VT, WI, WV]; Canada: AB (Griffiths 1972), [NS, ON, QC].</p></div>	https://treatment.plazi.org/id/038B879BFF7874DF12C0DCA7496BB693	Public Domain	No known copyright restrictions apply.

A.Gray (Scheffer et al. 2021).</p><p>Leaf mine. According to Griffiths &amp; Piercey-Normore (1995), the mine begins as a narrow linear channel on the lower leaf surface, then crosses to the upper surface and abruptly widens; frass is initially in closely spaced, fine, black particles and later in larger, more widely spaced pellets. Their illustration of the upper-surface portion makes clear that it is an entirely linear mine, not a “linear blotch” as stated by Lonsdale &amp; Scheffer (2011). The mines we observed were generally consistent with Griffiths &amp; Piercey-Normore’s (1995) description and illustration, although some were contorted to form secondary blotches.</p><p>Puparium. Brown; formed within the leaf, on either surface, with the anterior spiracles projecting through the upper or lower epidermis; according to Griffiths &amp; Piercey-Normore (1995), deep yellow to yellow-brown and normally on the lower surface.</p><p>Phenology and voltinism. In Newfoundland, Griffiths &amp; Piercey-Normore (1995) reported a univoltine life cycle. They observed adult host-feeding punctures beginning in mid-June but did not see initial lower-surface mines developing until mid-August, and the later upper-surface mines were first noted in late September. Pupation occurred in October, with some larvae completing their development in “green islands” on fallen, yellowing leaves, and adults emerged the following spring. This species is at least bivoltine as far north as Massachusetts; larvae and puparia were collected on 27 July, and adults began emerging the same day, with the last emerging on 20 August. Scheffer et al. (2021) did not report emergence dates, but reared adults from mines collected in April (FL, NY), June (NC), July (WV), August (WV), and September (WV).</p><p>Distribution.

Justification for the combination was not explained, and the species cannot be placed in either of the two major species groups historically treated as Chromatomyia on the basis of diagnostic features such as the supporting sclerite, including the P. periclymeni and P. syngenesiae groups. While analyses of the genus are ongoing, P. nemophilae will likely end up being placed in the P. ciliata group, which is quite dissimilar from the two aforementioned groups; von Tschirnhaus (2021) does not explain why three of 14 species in this group are included in his concept of Chromatomyia .</p></div>	https://treatment.plazi.org/id/038B879BFF7F74DE12C0DBBB490DB3FB	Public Domain	No known copyright restrictions apply.

When the plant material was collected, the mining appeared to extend from the stem into the same petiole in which the empty puparium was later found after the adult’s emergence. The stem also had an intact puparium in its interior in the pith, but this appeared to belong to a Melanagromyza species, which we presume fed exclusively in the pith and was not responsible for any of the externally visible mining.</p><p>Puparium. (Fig. 92) Whitish; formed within the petiole.</p><p>Phenology and voltinism. Our reared specimen emerged in early August from a stem collected in mid-July. Adults have been collected in late May (AB, QC), early June (NC, ON, QC), mid-June (CO, BC), and mid-July (ON); a specimen collected in early August in California is tentatively assigned to this species (Spencer 1969a; Spencer &amp; Steyskal 1986).</p><p>Distribution. USA: CA?, CO, *IA, NC; Canada: AB, BC, ON, QC (Spencer 1969a; Spencer &amp; Steyskal 1986).</p><p>Comments. This is only the second Nearctic rearing record for a species of the subgenus Napomyza, the first being a California specimen of Phytomyza (N.) plumea (Spencer) that was labeled “reared from yarrow” ( Asteraceae: Achillea L.) with no further details provided (Spencer 1981). Species of this subgenus, of which 14 are recorded from North America, are generally stem borers or feed in flower heads, pupating internally (Spencer &amp; Steyskal 1986). The otherwise Palearctic species P. (N.) lateralis Fallén has been caught in association with Tripleurospermum inodorum (L.) Sch.Bip. ( Asteraceae) in the Northwest Territories; in Europe it is known to bore in the stem or receptacle of this and various other asteracous plants, often ovipositing in the leaf, with the larva quickly moving through the midrib and petiole into the stem (Spencer 1969a).</p></div>	https://treatment.plazi.org/id/038B879BFF7D74DC12C0DB434C6CB6EF	Public Domain	No known copyright restrictions apply.

Lamiaceae: [ Melissa officinalis L.], Mentha *spicata L., M. suaveolens Ehrh., Origanum vulgare L. (Eiseman &amp; Lonsdale 2022).</p><p>Leaf mine. (Eiseman &amp; Lonsdale 2022: Figs. 1–6) Brown, upper-surface; initially narrow and linear, and essentially linear throughout, but typically contorted to form a secondary blotch that obliterates the early portion. When backlit, an intricate pattern of primary and secondary feeding lines is visible. Before pupating, the larva cuts an exit slit in the lower epidermis, often at the end of a linear track that leads away from the blotch.</p><p>Puparium. Pale straw-colored to dark brown or black; usually formed within the mine, but sometimes protruding from the exit slit to the extent that it falls out (Eiseman &amp; Lonsdale 2022).</p><p>Phenology and voltinism. Larvae and puparia have been collected in Massachusetts in late June, early July, early August, and mid-August, with adults emerging 8–26 days later (Eiseman &amp; Lonsdale 2022); those collected in mid-September and mid-October yielded adults the following spring.</p><p>Distribution. USA: [CT], MA; Europe (Eiseman &amp; Lonsdale 2022).</p><p>Comments. We are unable to confirm the identity of the females reared from Melissa since identification requires examination of male genitalia. However, the mines were entirely consistent with those of Phytomyza origani, which was present on Mentha in the same garden. Just one agromyzid species that is known to occur in North America, P. petoei Hering (QC), is recorded from Melissa in Europe; it has similar pupation habits but its mine is strictly linear, not forming a secondary blotch (Ellis 2024), and our reared females are not consistent with that species. Apart from the record of Liriomyza sativae involving a greenhouse experiment (Oatman 1959), the only other agromyzid recorded from Melissa prior to the present study is the polyphagous European species P. horticola Goureau, which also forms a strictly linear mine; its pale puparium is always formed within the mine (usually on the lower surface), with its anterior spiracles projecting through the epidermis, and without an exit slit prepared prior to pupation (unlike P. origani and P. petoei) (Ellis 2024). As documented above, a female of the unrelated species P. mimuli has recently been reared from Melissa in California; its pupation mode is like that of P. horticola .</p></div>	https://treatment.plazi.org/id/038B879BFF7C74DC12C0DC534CC3B1A7	Public Domain	No known copyright restrictions apply.

Elliott, [ A. × prunifolia (Marshall) Rehder, Prunus americana Marshall, P.?avium (L.) L., P. pensylvanica L.f.], P. persica (L.) Batsch, [ P. serotina Ehrh.] (Eiseman &amp; Lonsdale 2018).</p><p>Leaf mine. (Eiseman &amp; Lonsdale 2018: Fig. 200) Yellowish-green, upper surface; long, narrow, entirely linear; frass in discrete, well-spaced, black grains.</p><p>Puparium. Brown; formed within the mine, with the anterior spiracles projecting through the upper epidermis.</p><p>Phenology and voltinism. According to Frost (1924), adults emerge from overwintered puparia in New York and Pennsylvania around the beginning of June and begin laying eggs. Larvae of the first generation mature in mid-to late June, emerging as adults in late June and early July and laying eggs that give rise to the second generation. Scheffer &amp; Lonsdale (2018) likewise reported larvae being active in June in New York and emerging as adults within a few weeks. The female reared from Aronia in New Brunswick was collected as a puparium in mid-July and emerged as an adult later in the same summer. Peach leaves containing larvae or puparia in early August (CT) and mid-October (MA) have yielded adults the following spring or early summer (Eiseman &amp; Lonsdale 2018; Lonsdale 2021).</p><p>Distribution. USA: CT, MA, [MN], NY, OH, [PA, RI], VA, [VT]; Canada: [NB], NS, ON, [PE] (Lonsdale 2021).</p><p>Comments. Under the heading “ Phytomyza obscurella var. nigritella (Zett.) Melander)”, Frost (1924) reported having reared a species that was clearly P. persicae from peach ( Prunus persica), and it seems highly likely that the specimens he reared from black cherry ( P. serotina) were conspecific. Mines consistent with P. persicae have now been found on two additional native Prunus species as well as an ornamental, in addition to Aronia spp. Given this host range, it is remarkable how rarely encountered the mines are; Frost (1924) did note a high parasitism rate. Frost (1924) also reported rearing the same species from bush honeysuckle ( Caprifoliaceae: Diervilla lonicera Mill.), and presumably this was a superficially similar member of the P. periclymeni superspecies. None of Frost’s specimens of “ P. obscurella,” which were reared from leaves of peach, black cherry, and bush honeysuckle collected “at Arendtsville, Pennsylvania (where it is exceedingly abundant) and at Ithaca, New York,” were examined by Frick (1959) or later authors, nor are any P. persicae specimens known from Pennsylvania. The only Phytomyza species known to feed on D. lonicera is P. tarnwoodensis Eiseman &amp; Lonsdale, which makes a blotch mine entirely different from the linear mine of P. persicae . However, an old linear mine on D. lonicera with frass in discrete grains, and with a brown puparium at the end, has been photographed in Onondaga County, New York (iNat 101857741), and this presumably represents the species that Frost conflated with P. persicae . A contorted interparenchymal mine found on D. lonicera in Halifax, Nova Scotia (iNat 89679332) was probably made by the same species.</p></div>	https://treatment.plazi.org/id/038B879BFF6274C112C0D85D495CB20F	Public Domain	No known copyright restrictions apply.

A.Mey. &amp; Avé-Lall., T. pubescens Pursh (Spencer &amp; Steyskal 1986) . Frost (1924) reared the type series from T. pubescens (as T. polygamum) and Aquilegia canadensis, but Frost (1930) stated that the latter host was recorded based on confusion with P. aquilegiana, and P. plumiseta does not mine Aquilegia . Spencer (1969a) examined alleged paratypes of P. plumiseta that were reared by Frost “ex Thalictrum canadense, 3 Aug. 1926 ”; this is suspect both because this name does not apply to any Nearctic species and because the date on the specimens is two years later than the date of the original description. Spencer (1969a) also attributed to P. plumiseta young leaf mines on T. confine Fernald (sometimes considered a variety of T. venulosum Trel.) in Hering’s collection, collected in Montreal; this host requires confirmation by rearing, since the widespread species P. aquilegiana has now been reared from blotch mines on Thalictrum spp. (see above). Hansson (1987) listed a specimen of Chrysocharis oscinidis ( Eulophidae) reared from P. plumiseta on T. venulosum in Alberta, but this probably refers to an undescribed sister species we have seen from this host and locality. Eiseman &amp; Lonsdale (2018) reported probable mines of P. plumiseta on T. amphibolum Greene (as T. revolutum DC.), referring to photographic records from Iowa (BG 577023) and Wisconsin (BG 565475), but it is now clear that there are multiple species forming blotch mines on Thalictrum in the Midwest, and there is no basis for attributing mines on T. amphibolum to any of them until adults have been reared.</p><p>Leaf mine. A white blotch; see Eiseman &amp; Lonsdale (2018, including Fig. 201).</p><p>Puparium. Reddish-brown to dark brown, deeply segmented. Frost (1924) stated that the puparium usually rests in the center of the mine. According to Spencer &amp; Steyskal (1986), the puparium may be formed either within the mine or externally. We have only reared adults from external puparia, but we did collect a series of blotch mines on T. pubescens in Vermont, with larvae that formed puparia within, outside, and partly protruding from the mines; only braconids emerged from these.</p><p>Phenology and voltinism. Frost (1924) reported that larvae did not appear in New York and Pennsylvania until 5 July, and that they increased in numbers during late July through August and part of September. More recently, larvae have been collected in late May (MA), early June (NY), and late June (MN), with adults emerging within a month (Spencer &amp; Steyskal 1986; Eiseman &amp; Lonsdale 2018); larvae collected in mid-June (MI) and late July (QC) have yielded some adults 20–27 days later and some the following spring (Spencer 1969a).</p><p>Distribution. USA: MA, *MI, MN, NY (reported by Frost (1924) and confirmed in present study), PA; Canada: ON, QC (Eiseman &amp; Lonsdale 2018). Other tentative records based only on leaf mines, given by Eiseman &amp; Lonsdale (2018), require confirmation by rearing.</p><p>Comments.

Spencer (1969a) reported that Phytomyza canadensis Spencer (AB) forms a linear mine on Anemonastrum canadense, but Sehgal (1971) asserted that Spencer had confused this plant with Anemone virginiana L. (as A. riparia Fern.), and noted that Sehgal and Griffiths had found such mines only on A. virginiana, never on A. canadense .

F.Dietr., L. *involucrata (Richardson) Banks ex Spreng. (see Comments), [ L. japonica Thunb.], L. sempervirens L. (Eiseman &amp; Lonsdale 2018).</p><p>Leaf mine. (Fig. 212) Whitish, upper-surface; on Lonicera sempervirens, beginning as a small, stellate blotch with frass in a black central mass, after which the larva forms a linear mine (sometimes branching, or contorted to form a secondary blotch) with frass in discrete but closely spaced grains, generally forming two rows (Eiseman &amp; Lonsdale 2018: Figs. 203–204). On L. hispidula and L. ciliosa, multiple eggs are laid along the midrib, from which linear or branching tracks radiate, with mines made by adjacent larvae frequently becoming confluent. On all hosts, the larva usually ultimately switches to the lower surface, where it forms a more or less rounded blotch; multiple larvae may form a single communal blotch.</p><p>Puparium. White with a conspicuous dark band running centrally along the ventral surface; formed within the lower surface blotch with the anterior spiracles projecting through the lower epidermis. Occasionally the larva does not cross to the lower leaf surface and the puparium is formed with its ventral surface against the upper epidermis (Eiseman &amp; Lonsdale 2018).</p><p>Phenology and voltinism. Mines containing larvae or puparia have been collected in early April (AL, NC), late April (NC), early May (AR), mid-May (NC), late May (MA), mid-June (WA), late June (WA), early July (WA), late July (OR), and late September (NC), with adults emerging within 27 days in each case; a mine collected in late December (NC) yielded an adult the following spring (Eiseman &amp; Lonsdale 2018).</p><p>Distribution. USA: AL, *AR, [DC, GA], MA, [MD, MO, MS], NC, OR, [VA], *WA, [WI; Canada: ON].</p><p>Comments. The mines and puparium of Phytomyza sempervirentis perfectly match those described for P. nigrilineata (Griffiths), which was reared from Lonicera dioica L. in Alberta (Griffiths 1974a). Given the considerable variation in male genitalia now observed in P. sempervirentis, it seems possible that this species is synonymous with P. nigrilineata, but we prefer to wait until a revision of Canadian Phytomyza spp. is complete before making a final decision about this.</p><p>Additional blurring of species boundaries is seen in several of the Lonicera ciliosa -reared specimens from Millersylvania State Park, wherein dissected males agree with the type description except that the distiphallus is similar to that of Phytomyza palmeri, a miner on Symphoricarpos orbiculatus (see original description for a full comparison of the two species). The distiphallus (viewed ventrally) is thicker and parallel-sided with the characteristic flat, rounded lateral lobes reduced to absent. One additional male (CNC5181215, reared from L. hispidula) agrees with one type specimen (Eiseman &amp; Lonsdale 2018: Figs. 358, 359) except that the distiphallus is wider basally with the lobes darker marginally, and unlike any other male, there is a very small speck-like spot on the hypophallus laterally. This is relevant to note as the absence of any sclerotization on the hypophallus is a key diagnostic character, and a possible synapomorphy of it and several putatively related species.</p><p>The rearing of P. sempervirentis from Lonicera involucrata is surprising, since this is a shrub honeysuckle in the subgenus Lonicera, whereas all other known hosts of this species are climbing honeysuckles in the subgenus Caprifolium (except for L. japonica, a climbing species of the nominate subgenus, from which adults have not been reared). We have seen no photographic evidence of the characteristic striped puparia of P. sempervirentis being found in leaves of L. involucrata, and the reared specimens emerged from a collection of old, deteriorating mines that were not closely examined (E. Stansbury, in litt.). Further rearings of Phytomyza from this host would be desirable, to clarify the mine and puparium characteristics of the form that is identified here as P. sempervirentis, as well as those of P. involucratae Spencer, which has been associated with this host but never reared.</p></div>	https://treatment.plazi.org/id/038B879BFF6674C512C0DEE64C83B4F7	Public Domain	No known copyright restrictions apply.

The mines from which the new specimens were reared were the basis for the tentative records of Solidago altissima and Michigan given for Phytomyza astotinensis Griffiths by Eiseman et al. (2021). Larvae of P. solidaginophaga had not previously been found at such a late date, and we had failed to appreciate how delayed the phenology of Michigan’s Upper Peninsula is relative to Massachusetts, where larvae of P. astotinensis have been found as early as 9 June. Mines found as early as 26 April in Pennsylvania, 28 April in New Jersey and Virginia, and 6 May in Ohio (listed above) seem safe to attribute to P. solidaginophaga; empty mines found on S. flexicaulis in Maryland on 15 May (iNat 117369876) and in the mountains of Virginia on 18 May (iNat 163802097) also may represent this species, but rearing of Solidago -feeding Phytomyza at these lower latitudes is needed to clarify what species are present and how their phenologies compare.</p></div>	https://treatment.plazi.org/id/038B879BFF6574C412C0D82B4B66B30B	Public Domain	No known copyright restrictions apply.

Puparia have been found as early as 27 April in Ohio and 1 May in Illinois, with adults emerging from the latter five days later, although no specimens were saved to confirm their identity (BG 1225272). Specimens we have examined all emerged within 15 days from puparia collected in mid-May (IA, OH), early June (MI, PA), mid-June (CT, MI, NB), late June (IA, MI, WI), early July (NB, NS, ON), mid-July (MI), late July (MI), late August (MI), and early September (MA) (Fig. 90).</p><p>Distribution. * USA: CT, IA, [IL, IN], MA, [MD, ME], MI, [MN, ND, NE, NJ, NY], OH, PA, [RI, VA, VT], WI, [WV]; * Canada: [MB], NB, [NL], NS, ON, [PE, QC]; Europe (Guglya 2021).</p><p>Comments. This European species has not been reported from North America previously. The earliest record we have seen is a leaf mine photographed in Wisconsin in 2014. Similar observations were initially restricted to adjacent midwestern states, with mines found in Illinois in 2015, and in Iowa and Michigan in 2017. The first Canadian record, in Ontario, was in 2018, as was the first Pennsylvania record. In 2020, mines were found in Manitoba, Minnesota, Ohio, New York, and New Jersey. In 2021, mines were documented in New England (Connecticut, Rhode Island, Maine, Vermont) and adjacent Canada (Quebec, Nova Scotia, Prince Edward Island), as well as in North Dakota. In 2022, the first mines were found in New Brunswick, Nebraska, and Maryland; in 2023, mines were found in Massachusetts and Virginia; and in 2024 mines were found in Newfoundland and Indiana. Similar yellow to pale green, linear mines have been photographed in states farther south, but in all cases when the lower leaf surface is shown, no puparia are evident, so we are hesitant to attribute them to P. spinaciae: Georgia (2021) on Cirsium horridulum Michx. (iNat 80682743; possibly a Liriomyza mine given that some frass appears to be in strips); Louisiana (2021) on C. horridulum (iNat 70214999) and an undetermined thistle (iNat 76183146); Mississippi (2023) on an undetermined thistle (iNat 161327597). The same is true of mines found on C. altissimum (L.) Spreng. (an otherwise undocumented host) in Illinois (iNat 86892017, 86892239).</p><p>Phytomyza spinaciae has so far been found only on Cirsium spp. (thistles) and Centaurea spp. (knapweeds) in North America, although similar mines and puparia found on Arctium (burdock) in Manitoba (iNat 217930684) may also represent this species. In Europe it is recorded from other genera of Cardueae ( Carduoideae) including Carduus, Onopordum, and Serratula (Benavent-Corai et al. 2005), with a single record of a specimen reared from Leontodon hispidus L. ( Cichorioideae) in Lithuania (Pakalniškis 1994). The very similar European species P. autumnalis Hering makes identical mines on the same plants, but its larvae do not appear until October and its puparia are metallic black. There is no indication that P. autumnalis is present in North America.</p></div>	https://treatment.plazi.org/id/038B879BFF6474CA12C0DAF74CBEB42B	Public Domain	No known copyright restrictions apply.

Two Holarctic Phytomyza species are known to form linear mines on Angelica, and of the two, the photographed mine matches P. pastinacae, which is confirmed in North America only from Alberta and New York. The mine of P. archangelicae Hering, known from Alaska and Montana (Winkler et al. 2009), begins with a short channel on the lower leaf surface (unlike the mine from which this female was reared) and then switches to the upper surface (Griffiths 1973).</p></div>	https://treatment.plazi.org/id/038B879BFF6874C812C0DEE64C60B5F3	Public Domain	No known copyright restrictions apply.

These females are characterized by a black, thick and enlarged first flagellomere, a gray velvety frontal vitta contrasting a mostly yellow orbital plate, and a matt gray scutum with very few acrostichal setulae. They are likely conspecific with one of two previously undocumented or undescribed species in Ontario or (more likely) Yukon that will be more thoroughly treated in a revision of the Canadian Phytomyza (Lonsdale, in manuscript). A member of the P. affinis species group (referred to as the P. atomaria group by Winkler et al. (2009)), its occurrence on Plantaginaceae is unsurprising.</p><p>The 2024 collection of these mines produced adults of Eupelmus messene Walker ( Eupelmidae; CSE8976, CNC) and undetermined Entedonini ( Eulophidae; CSE8931, CSE8948, CNC), all emerging from puparia.</p></div>	https://treatment.plazi.org/id/038B879BFF6874C812C0DD6E4D55B16F	Public Domain	No known copyright restrictions apply.

Caprifoliaceae: Symphoricarpos orbiculatus Moench.</p><p>Leaf mine. Upper-surface, whitish with some brown patches; beginning at the base of the leaf, with several branches radiating to either side of the midrib; from here a linear mine meanders through the rest of the leaf; frass in discrete, closely spaced, black grains (BG 2119652).</p><p>Puparium. Brown; formed within the mine, with the anterior spiracles projecting through the upper epidermis.</p><p>Phenology and voltinism. A larva collected in mid-May emerged as an adult about three weeks later.</p><p>Distribution. USA: NC.</p><p>Comments. This unidentifiable female is entirely dark, and does not match the paler Phytomyza palmeri, which is the only Phytomyza species known to feed on Symphoricarpos orbiculatus, as well as the only Symphoricarpos - feeding Phytomyza known to occur east of the Great Plains. The adult does not disagree with the female treated as Phytomyza sp. 4 in Eiseman &amp; Lonsdale (2018), reared from S. orbiculatus in Colorado, but that specimen was reared from a collection of simple linear-blotch mines with a different frass pattern. Mines possibly representing the same species as the North Carolina female have been photographed on S. orbiculatus in Virginia (iNat 101649881); all are similarly digitate, but not all begin at the base of the leaf, and none develop into simple linear mines. Mines that are initially digitate and do develop into meandering linear mines have been found on S. albus in Ontario (iNat 94038087), perhaps representing the otherwise western P. fricki (Griffiths) .</p></div>	https://treatment.plazi.org/id/038B879BFF6874CF12C0D8D24B8FB55F	Public Domain	No known copyright restrictions apply.
