Genital chamber (uterus) posteriorly with distinctive dark-pigmented internal sclerotization ( Figs 291, 292) formed by 1 compact crooked ventral sclerite (similar to that of  A. dissors), a pair of relatively long, nat and paler dorsal sclerites (these are absent in  A. dissors) and 1 subcircular, curved (in pronle) annular sclerite situated in front of the former. Membranous part of genital chamber large but without additional sclerotizations ( Fig. 290). Ventral receptacle ( Fig. 290) very slender (also basally), tube-like, hyaline, terminally with multiply twisted vermicular apex. Accessory gland small, vesicular, hyaline, on distally slightly dilated and sparsely ringed duct. Spermathecae (1+1) broadly suboval to ovoid ( Figs 288, 293), each with distinct, narrow but deep invagination and a number of short blunt spines in basal fourth surrounding duct insertion; duct very long and ending simply (without distinct cervix) in centre of spermathecal body. T10 small ( Fig. 287), suboval to rounded trapezoidal (distinctly wider than in  A. dissors), ochreous to yellow, with 2–3 pairs of setae (1 long) and reduced micropubescence. S10 pale brown to yellow, somewhat larger and wider than T10, suboval in ventral view ( Fig. 289), nnely setulose and micropubescent. Cercus relatively short ( Figs 291, 380), not slender, with numerous nne and relatively short setae, apical and dorsopreapical longest.   Discussion.  Anthomyza mcalpinei sp. nov.belongs to the  A. pallidagroup, as denned above. Its closest relatives are the Palaearctic  A. dissorsand the W. Nearctic  A. pullinotum sp. nov.; their close relationship can be justined not only from external appearance (thorax often with dorsal darkening, pleura always yellow) but particularly from highly similar structures in the male and female genitalia, including such nne details as: nnely spinulose basal membrane with acute spinulae laterally and nat short ones medially; subterminal membranous lobe-like dilation of the nlum of distiphallus; connecting sclerite distally with a cluster of dark spines; female T7+S7 with original T7 expanded as narrow lobes that almost meet ventromedially (sometimes even meeting in  A. dissors); and female genital chamber with compact unpaired ventral sclerite (interpreted to be a fusion product of a pair of ventral sclerites as known in other relatives of the  A. pallidagroup).At least some of the above characters can be considered synapomorphic and diagnose the  A. dissorssubgroup. Interestingly, each of the three species belonging to this subgroup has a differently armed aedeagal part of the folding apparatus.  Anthomyza pullinotumexhibits the plesiomorphic state of a group of nne dark tubercles, which is also seen in the rest of the  A. pallidagroup outside of this subgroup. Derived states are seen in the other two species of the subgroup, with the tubercles in  A. dissorsreduced and hyaline, and those of  A. mcalpineireduced to a few enlarged wart-like spines.  Anthomyza mcalpineiundoubtedly is the nearest ally of the Palaearctic species  A. dissors, demonstrated not only by their external resemblance (including the colour variability of the body, mainly of the mesonotum and abdomen), but chieny by almost identical structures in the male and female genitalia, especially a similarly formed ventral sclerite and a reduced number of dorsal sclerites in the female genital chamber.   Anthomyza mcalpineidiffers from both above relatives in having the occiput laterally normally only darker yellow (without brown areas behind eyes); the pleural part of the thorax entirely yellow and without a dark dorsal stripe (but pleura in  A. pullinotumalso is usually unicolourous yellow); male S6 and S7 yellow, contrasting with blackish brown epandrium; gonostylus apically not pointed but with distinct posteroapical teeth ( Fig. 286); aedeagal part of folding apparatus with a few dark blunt spines; saccus with fewer (usually 6) robust dark-pigmented spines; female thorax never brown dorsally; female 7th segment with a distinct S7 that is not fused with T7 ( Fig. 289); and female genital chamber with only a single pair of nat sclerites above the single compact and crooked ventral one.   Etymology.This common species is named in honour of J. F. McAlpine, a preeminent Canadian dipterist whose body of work on acalyptrate Dipterasystematics serves as an inspiration to the junior author, whose graduate committee he served on.   Biology.There are fewer western records for  A. mcalpineicompared to  A. pengellyi, and include collections from pure stands of  Calamagrostis canadensis(Alberta: w. border of ElkIsland N. P.) and  Carex utriculata(British Columbia: Fernie). In the east, the primary plants from which this species has been taken are the grasses  Phalaris arundinaceaand  C. canadensisand sedgessuch as  Carex aquatilis,  C. utriculataand  Scirpus microcarpusJ. & C. Presl. There is a single record from “mostly”  Carex strictaLam.(Ontario: Manitoulin Is. – Misery BayNature Reserve) and repeated collections from  Carex stipataMuhl. ex Willd. var. stipata(Ontario: Sault Ste. Marie – Finn Hill). Beaverdams and meadows are mentioned on labels, with some including additional reference to sedges(Ontario: S of Sioux Narrows, ~ 5 kmSE Searchmont, Finland– S of Caliper Lake). A “pasture sweep” yielded  A. mcalpinei(Newfoundland: PortugalCove) while another less specinc collection indicates “ grassesat edge of agricultural neld” (Alberta: Dunvegan), a site shared with  A. pengellyiand  A. vockerothi. Various other plants such as  Equisetum,  Typha,  Solidago,  Rubusand ferns can be included but it is the graminoids in these plant mixtures or growing nearby that are the most likely hosts. A mixed riparian community (Ontario: Greenwater P. Pk., Fig. 279) was dominated by  Carexspp.,  C. canadensis, and  P. arundinacea(from higher to lower prevalence) while a drier adjacent upstream area, dominated by  P. arundinacea, also yielded specimens. There is a singular site in Sault Ste. Marie, Ontario (S of Algoma University) where several hundred specimens were collected over a number of years. This is a small, narrow site that supports a mixture of  C. canadensisand  C. aquatilis, each transitioning to dominance at either end of a forest edge with a dense patch of  P. arundinaceain the middle. This narrow stretch is bordered on the opposite side by a raised municipal snow dump and a wetter area dominated by  Typha latifoliaL. Whilemost of the collection effort was expended in sampling from the  C. aquatilis(primarily for syntopic  A. gibbigerand  A. orthogibbus),  A. mcalpineiwas also very abundant on  C. canadensisat this site, but also present at lower numbers on  P. arundinacea. More than 150 eggsof  A. mcalpineiwere obtained from a collection of nine females with three males (Ontario: Sault Ste. Marie – S of Algoma University) and used in a rearing attempt over the period of 8 August to 20 September 2002. The three dominant species of plants from this site (  C. aquatilis,  C. canadensis, and  P. arundinacea) were initially offered to the adults and the subsequent larvae, but on 14 September all (~34) surviving larvae were transferred to  P. arundinaceae. The single puparium (21 September) which yielded an adult female (4 October) originated from eggs laid on  P. arundinacea; the pupariation period at 20°C was 13 days. The remaining nve larvae were transferred to 10°C on 3 November but were dead by 29 November. Despite the lack of success reported here, one or more of these graminoids are likely to serve as a natural host for  A. mcalpinei. Adults of  A. mcalpineihave been collected from 3 June (Minnesota: WillowRiver) to 16 September (Ontario: Sault Ste. Marie).   Distribution.This commonly collected species has a transcontinental distribution in Canadaand the northern United States of Americathat is similar to, but latitudinally narrower than that of  A. pengellyi. It has not yet been recorded in New Mexicoin the southwest or in the northern jurisdictions of Alaska, Yukon, Northwest Territories and Labrador, although it has been recorded from Newfoundland and Prince Edward Island in the northeast. The list of records includes Canada: Alberta, British Columbia, Manitoba, New Brunswick, Newfoundland, Nova Scotia, Ontario, Prince Edward Island, Quebec, Saskatchewan; United States of America: Colorado, Idaho, Massachusetts, Michigan, Minnesota, Montana, New Hampshire, New York, Oregon, Washington, Wisconsin(see Table 2, Fig. 599). 2985226544 2001-06-25 DEBU J.
