Korneyev and V. Korneyev 2025	<div><p>Parastenomyia Kameneva, S. Korneyev and V. Korneyev, new genus</p><p>urn:lsid:zoobank.org:act: 619840EE-48F4- 4D06-AD68-126472AF74A6</p><p>Type species: Parastenomyia waynei, new species .</p><p>Diagnosis.— Parastenomyia shares the wing pattern with four dark crossbands and frons with long ocellar, interfrontal, and frontal setae and very short parafrontal setulae lateral to them, with Aspistomella gtoup of genera (Kovac et al. 2024), the Chaetopsis group of genera (see below), and Amethysa Macquart 1835 (Kameneva et al. in prep.) of the tribe Lipsanini . It has the abdomen elongate with narrowed pleura, long oviscape, and dorsoventrally flattened aculeus in females and surstyli spread apart laterally and bearing only fine mesal setulae in males, as in the Chaetopsis group of genera: Chaetopsis, Eumecosomyia, Eumetopiella, Hypoecta, Steneretma, Stenomyia, and Zacompsia (Kameneva et al., in prep.) and belongs here, but differs from other genera by the vein R 1 setulose dorsally along the pterostigma (bare in the other genera of the group) and the apically pointed aculeus (blunt or truncate in other genera).</p><p>Description.—Body dark brown with sparse white microtrichia, dark brown setulae and setae.</p><p>Head (Figs. 9–12, 15–17, 34, 38, 44, 45): Brownish yellow to black on vertex and occiput; entirely microtrichose, densely on orbits, dorsal half of face, occiput and postgena. Chaetotaxy: very long inner (medial) vertical seta and outer (lateral) vertical seta; ocellar, posterior orbital; and postocellar setae half as long as inner vertical seta. Frons with one reclinate anterior orbital seta and 6–8 inclinate frontal and interfrontal setae and a row of fine parafrontal setulae along eye margin (see Kovac et al. 2024: fig. 3A); postgenal and genal setae and 5–6 proclinate parastomal setae as long as frontal setae. Frontal vitta covered with fine oppressed microtrichia, matt. Lunule narrow, nonsetulose, matt. Epistome short, very slightly protruding anteriorly, shining, sparsely microtrichose. Gena matt, either wrinkled, or with oppressed microtrichia or nonmicrotrichose except genal dilation. Antenna: scape dorsally with 6 black setulae; pedicel with conspicuous notch; mesally with 9–12 short but stout setulae in 2–3 rows and moderately long pedicellar seta, laterally with single marginal row of 18–20 setulae, ventralmost as long as pedicel; postpedicel ovoid, apically rounded; arista 2-segmented, with very short, oppressed microtrichia, virtually bare. Clypeus almost half as high as epistome, microtrichose. Palpus microtrichose, moderately densely and long setulose; prementum bulged, sparsely setulose and microtrichose.</p><p>Thorax: Dark brown to black, with silver, often bluish sheen, sparsely white microtrichose and dark brown or black setulose. Proepisternal ridge with 8–10 setulae in 2 irregular rows; 1 short proepimeral seta (Fig. 51). Scutellum subshining, shagreened, slightly flattened. Chaetotaxy as in most other Lipsanini: 1 postpronotal, 2 notopleural, 1 prescutellar acrostichal, 2 dorsocentral, 1 intra-alar, 1 postsutural supra-alar, 1 postalar, and 2 pairs of scutellar setae well developed; 1 anepisternal and 1 katepisternal setae slightly shorter than anepisternal seta; 6–8 rows of setulae between dorsocentral rows.</p><p>Legs: unmodified; as in other Lipsanini . Mid tibia usually with one long ventroapical and one shorter (half of length of longest seta) or with 4 subequally long setae (Figs. 53–54).</p><p>Wing (Figs. 5–8): With four dark crossbands separated by hyaline interspaces; costal cell twice as long as pterostigma; pterostigma elongate, 4–5 × as long as wide; vein R 1 dorsally with 3–10 setulae on section along pterostigma; apex of vein R 1 just proximal of middle of wing; crossvein r-m at mid-pterostigma level near middle of cell dm; ultimate section of vein M 1 twice as long as penultimate. Cell cua (= cup) with moderately short postero-apical lobe (shorter or at most as long as cell width); vein CuA+CuP complete, reaching wing margin. Halter yellow.</p><p>Abdomen (Figs. 20, 28, 48): Moderately narrow, lengths of tergites 3–5 of both sexes subequal. Tergite 6 of female narrow, hidden underneath tergite 5, bearing one row of 6–8 setulae; sternites 3–5 (–6) wider than long and 4–5 × as wide as pleural membrane (Figs. 20, 28).</p><p>Male genitalia (examined only in P. waynei): Sternite 8 setulose, with 2 setae twice as long as other setulae. Hypandrium anteriorly with deep pouch; pregonite rounded, almost flat, with 8–9 short setulae scattered along its lateral margin (Figs. 23, 26, 27). Phallic guide deep, its lobes narrowly triangular, slightly pointed towards posterior end; postgonites (sensillar fields) laterobasally at middle of phallic guide, separated by membranous stripe from pregonites, each with 4–5 short trichoid sensilla (Fig. 26). Basiphallus (Fig. 26) moderately large, as wide as phallic guide; distiphallus with a few inconspicuous microtrichia, strongly narrowed beyond phallic guide, membranous apically (Figs. 21–24). Epandrium (Figs. 21–24) lower than wide in posterior view and longer than high in lateral view, with surstyli widely spread at bases and with spatulate and apically rounded, mesally directed, apical portions; basal part of medial (inner) surstylus with row of 5 moderately short and thin setulae (Figs. 23–25, 27). Cerci setulose, very short, separated by membranous area (Figs. 22–24). Phallapodeme low, phragmalike. Sperm pump long, almost as long as ejaculatory apodeme (Fig. 21).</p><p>Female genitalia: Oviscape long, as long as tergites 3–6 combined and twice as long as wide, spiracles at its anterior margin (Fig. 28); eversible membrane nearly as long as oviscape, with rounded postero-medial lobe of oviscape antero-dorsally and antero-ventrally, with two pairs of sclerotized taeniae half as long as membrane, medial vittae of sclerotized blots impregnated into membrane on dorsal and ventral sides; middle portion of membrane with blunt triangular, slightly sclerotized scales, gradually transitioning into taeniae and vittae and posteriorly into very short, non-sclerotized multidentate scales (Figs. 31–34). Aculeus (Fig. 29, 30, 35, 41–43, 49–50) conspicuously flattened dorso-ventrally, narrowly triangular on apical quarter with apex sharply pointed; sternite and tergite 8 with rows of short setulae (mechanoreceptors); cercal unit (Fig. 35) seamlessly fused to tergite 8, triangular, with long anal slit; on dorsal side with pair of moderately long setulae, shorter ventral setulae at sides of cercal pads; apex narrowly pointed, not truncated, with 2–3 short and 1 longer preapical setulae. Ventral receptacle (Fig. 31) as in other Ulidiidae, round and flat, non-sclerotized, on short petiole. Two cuplike, smooth spermathecae with wide inverted “collars” or “necks” (Fig. 36).</p><p>Distribution.—Central (Costa Rica) and South America (Ecuador, Peru).</p><p>Biology.—Unknown. Judging from having the flat and long aculeus, these species may be associated with poaceous grasses, ovipositing into sheaths between stem and leaf (or cob and husk of corn), like other members of the Chaetopsis group of genera.</p><p>Comments.—A preliminary phylogenetic analysis (Kameneva and Korneyev, in prep.) shows that Parastenomyia certainly shares synapomorphies with the other taxa of the Chaetopsis group (narrowed abdominal pleura, wide epandrium and surstyli without stout prensisetae, long oviscape, flattened aculeus), but it is a basal lineage within that group, showing several character states generalized or believed to be of plesiomorphic condition in the group or in the Lipsanini (developed interfrontal setae, blunt postpedicel, setulose R 1, wide abdominal sternites, long dorsal and ventral setulae on cercal unit), but possessing shining mesonotum and abdomen (microtrichia more sparse than in most Lipsanini) and narrowly acute, pointed cercal unit of female (rounded or blunt in all other Lipsanini) and extremely narrow phallus (character known only in P. waynei).</p><p>Such a combination of character states show the separate position of the species described below and the necessity to establish for them a new genus. The following key can be used to differentiate it from the other genera of the Chaetopsis group.</p><p>Key to species of the genus Parastenomyia ( Lipsanini)</p><p>1. Mid tibia with one moderately long and one shorter ventro-apical setae less than 1.5 × as long as tibia width (Fig. 52).

Lunula reddish brown, face and clypeus black. Epistome 1.2 × as high as clypeus. Epistome and clypeus with bluish sheen. Eye 1.6 × as high as long and 6.7 × as high as gena. Postpedicel 1.5 × as long as wide. Otherwise as in as in P. peruviana .</p><p>Thorax (Figs. 3, 46): As in P. peruviana . Scutum with strong blue sheen; pleura with somewhat denser microtrichia.</p><p>Legs: Fore coxa brown, otherwise as described for P. peruviana .</p><p>Wing (Figs. 3, 7, 47): 5.5 mm long, 2.7 × as long as wide. Vein R 1 in apical section with 9–10 setulae dorsally along pterostigma. Wing pattern as in P. peruviana, differing as follows. Medial hyaline interspace as wide as discal and subapical crossband. Subapical crossband 1.1 × as wide as vein dm-m length, widely fused with apical band in cells r 1 and r 2+3; preapical hyaline interspace narrow, inconspicuous in cell r 2+3, widened to posterior margin in cells r 4+5 and m 1, anteriorly reaching only vein R 4+5, and separated from posterior margin in cell m 1 by gray microtrichose area. Apical band wide.</p><p>Aculeus flattened, with pointed apex.</p><p>Distribution.— Ecuador.</p><p>Type data.— Holotype female, ECUADOR: Napo Prov., Huahua Sumaco, km 45, on Hollin-Loreto rd, Malaise trap, 20 Dec 1989, M. and J. Wasbauer and H. Real (CSCA) .</p><p>Remark. Both P. peruviana and P. ecuadoriana are known only from their two holotype females. Though nothing is known about the variability of their wing patterns, they generally exhibit common intraspecific differences in this group of Lipsanini genera. Remote localities (&gt; 1,100 km apart) with similar rainforest habitats on the eastern slopes of the Andes can be inhabited by populations of the same or different species. We therefore provisionally describe them as separate species, reserving the option to reconsider their status in a future revision involving more extensive material and molecular analysis.</p></div>	https://treatment.plazi.org/id/9632878AFFA10E32ADC2FC074E5CFA1E	Public Domain	No known copyright restrictions apply.

It looks most similar to P. waynei in having a moderately narrow subapical crossband, but differs from it also by the slightly less pointed aculeus: the distance from the basal most of the three subapical setulae and the apex 1.7–1.8 × longer than the distance between the basal most setulae (in P. waynei, 3.5 ×, in P. peruviana 3.1 ×).</p><p>Description.—Medium-sized, body length ≈ 7 mm (6.3 mm without head), subshining brown-black fly with bluish sheen and banded wings.</p><p>Head missing in the holotype.</p><p>Thorax (Fig. 48): Prothoracal segments as in Fig. 51, otherwise as described for P. peruviana . Scutum with strong blue sheen; pleura with somewhat denser microtrichia.</p><p>Legs: As in P. peruvianam but mid tibia with 3–4 subequally very long apicoventral setae, each 2 × or more as long as width of tibia (Figs. 53, 54).</p><p>Wing (apical halves of both wings clipped; Figs. 42, 43): ≈ 4.5–5.2 mm long, 1.8 mm wide. Vein R 1 in apical section with 10 setulae dorsally along pterostigma. Wing pattern apparently similar to P. waynei (especially in male), differing as follows. Prediscal hyaline interspace 1.0–1.2 × as wide as discal band. Medial hyaline interspace as wide as discal and subapical crossband. Subapical crossband 1.1 × as wide as vein dm-m length, widely fused with apical band in cells r 1 and r 2+3; preapical hyaline interspace narrow, inconspicuous in cell r 2+3, widened to posterior margin in cells r 4+5 and m 1, anteriorly reaching only vein R 4+5, and separated from posterior margin in cell m 1 by gray microtrichose area. Apical band apparently wide, proximally reaching middle of cell m 1.</p><p>Aculeus (exposed in the holotype) flattened, apex less pointed than in distance from basal most of 3 subapical setulae and apex 1.7–1.8 × longer than distance between basal most setulae.</p><p>Distribution.— Peru.</p><p>Type data.— Holotype female, Peru:“Pachitea-Münd” [ mouth of the Pachitea River, tributary of Ucayali River; -8.77, -74.53], 150 m, 24 Nov 1903, [O. Garlepp leg. (red stripe on green label)] (SDEI) .</p><p>Remark. The holotype, the unique female specimen, certainly belongs to the genus Parastenomyia . Despite its severe damage, it can easily be recognized as a new species based on its key characters. While being a scholarship holder at the Deutsches Entomologisches Institut, possibly in 1937, Willi Hennig identified it as “ Euxesta sp. (nov.)”. The specimen originated from Otto Garlepp’s collection at the Museum für Tierkunde Dresden, where Hennig had volunteered prior to receiving the scholarship.</p><p>Etymology. This species is named after Willi Hennig (1913–1976), who was the first to recognize it as a new, previously undescribed species.</p></div>	https://treatment.plazi.org/id/9632878AFFA10E33AFF2FA7F4957FCFB	Public Domain	No known copyright restrictions apply.
