Total body length 2.18–2.94 mm; bicolourous, yellow ventrally and laterally and (relatively pale) brown dorsally, largely dull, dorsal parts of thorax and abdomen distinctly pale grey microtomentose. Head slightly higher than long, anteriorly (at antennal base) rather rounded in pronle with face very slightly receding, almost entirely yellow, only ocellar triangle and lateral spots on occiput brownish. Occiput slightly concave, medially with usual pair of silvery white microtomentose spots (largely fused ventrally above foramen), laterally to them at least with crescent-shaped ochreous to brown areas which, in darkest specimens, can be expanded dorsolaterally to reach eye margin. Frons relatively narrow, largely dull yellow, lighter anteriorly and on orbits, darker (to orange) medially in front of frontal triangle; ocellar triangle brown to dark brown and greyish microtomentose; frontal triangle dark yellow to orange and dull, narrowly margined by some golden microtomentum; stripes between the latter and orbits silky yellow; orbits whitish microtomentose up to posterior ors, subshining more posteriorly. Frontal triangle narrow and rather short, reaching at most to anterior third of frons. Frontal lunule minute, yellow. Face narrow, medially concave to folded, and, like parafacialia and gena, yellowish white with silvery white microtomentum; marginal stripe of parafacialia and gena golden yellow; postgena and mouthparts whitish yellow to yellow. Cephalic chaetotaxy (setae usually paler than in relatives): pvt relatively long and often strongly crossed; vti and oc longest of cephalic setae; vte and posterior ors usually slightly shorter than vti; 3 ors but only 2 long, middle ors slightly shorter than to as long as posterior ors; 1 shorter anterior ors setula well developed; 1–2 (usually) pairs of medial microsetulae in anterior third of frons but none in front of anterior ors setula; 1 small setula behind vte; postocular setulae (7–8) short, in single row; postgena with several setulae and 2 relatively small posteroventral setae; 1 vi (usually weaker but sometimes as long as posterior ors), subvibrissa small, normally slightly longer than anterior peristomal; only 3–4 nne peristomal setulae. Palpus light yellow, with 1 ventral preapical seta and several (6–7) small setulae subapically and ventrally. Eye convex, subovoid (widest in anteroventral half), with longest diameter oblique and about 1.4 times as long as shortest. Gena relatively high; its shortest height about 0.15 times as long as shortest eye diameter. Antenna strongly geniculate, pale yellow, 1st nagellomere with short white pilosity. Arista brown but basal segments yellow, about 1.8–1.9 times as long as antenna, with shorter ciliation than on 1st nagellomere.
Thorax slightly narrower than head, laterally yellow but dorsally mostly brown with light grey (often with bluish tinge) microtomentum. Scutum entirely or largely brown to greyish brown, in latter case with yellow or ochreous longitudinal vittae (of various length) on dc lines, in palest specimens also anterior third of scutum yellow; notopleural area and dorsal part of humeral callus yellow but lateral side of the latter always brownish; scutellum yellow on disc only in lightest specimens, otherwise partly or completely brown; both scutum and scutellum distinctly pale grey microtomentose and dull. Pleural part of thorax more shining than scutum, all brightly yellow, only in darkest specimens with very narrow brownish darkening at dorsal (rarely also posterior) margin of mesopleuron. Postscutellum and postnotum brown to dark brown. Thoracic chaetotaxy (setae usually paler than in relatives): 1 hu plus 2 (1 longer) setulae on humeral callus; 2 npl (anterior longer than hu, posterior shorter); 1 weak prs (about as long as hu); 1 sa and 1 pa (both weak as prs, pa often shorter); 2 usual postsutural dc (anterior markedly shorter) and 4–6 dc microsetae in front of them (the hindmost distinctly enlarged, sometimes resembling a 3rd dc macroseta); 3–4 rows of ac microsetae on suture, only 2 rows between dc macrosetae and posteriorly not reaching to level of posterior dc; 2 sc, apical as long as posterior dc (longest thoracic setae), laterobasal very weak, shorter than sa; 1 minute ppl; 2 long stpl, anterior shorter, and 2–4 setulae in dorsal half of sternopleuron, its ventral part with 3–4 longer setae. Scutellum rounded triangular, very slightly convex dorsally. Legs yellow to pale yellow, only last tarsal segments of all tarsi dark brown in distal half to three-fourths; setosity of all legs pale ochreous yellow except for brown ctenidial spine, ventroapical seta on t 2 and ventral setulae on mid basitarsus. f 1 with ctenidial spine slightly to distinctly longer than maximum width of t 1. f 3 with posteroventral row of sparse erect setae; only 4–5 of them in distal two-nfths shortened and thickened; t 2 with moderate ventroapical seta; fore and hind basitarsus proximoventrally with several (usually 2–3) longer pale setulae; also 1–2 proximoventral setulae in mid basitarsus somewhat prolonged but brown; other parts of legs simply setulose. Wing (Fig. 274) elongate, moderately narrow, with pale yellowish ochreous veins and membrane. C with very sparse spinulae between apices of R 1 and R 2+3. R 2+3 long, parallel to C with apex very slightly upcurving; R 4+5 very slightly bent to almost straight, usually very slightly divergent from M (this almost straight) towards apex. Discal cell (dm) long, moderately narrow; r-m situated near the middle of cell dm or slightly basal to the midpoint. Apical portion of CuA 1 slightly to distinctly longer than dm-cu and almost reaching wing margin; A 1 short, ending far from it. Alula distinct but narrow. Wing measurements: length 2.18–2.88 mm, width 0.73–0.99 mm, Cs 3: Cs 4 = 1.03–1.32, rm\dm-cu: dm-cu = 1.82–2.65. Haltere pale yellow to yellowish white.
Abdomen. Preabdominal terga pale brown to brown, subshining but distinctly pale grey microtomentose and relatively shortly and usually pale setose. T1 and T2 only laterally partly fused; T1 shorter than T2 and distinctly narrower than T3. T3–T5 subequal in size, reaching onto lateroventral side of abdomen. Preabdominal sterna pale yellow (S2 sometimes darker yellow), not very narrow and becoming wider posteriorly, S2 slightly, S3–S4 more and S5 distinctly transversely trapezoidal, the latter being the largest and widest sternum; sterna nnely setose, only S1 bare and with darker posterior marginal stripe. T6 short (less than one-third of T5), transverse, bare, medially broadly unpigmented, with only lateral parts pale brown. S6 and S7 strongly asymmetrical and fused dorsally, brown as T5, both with more sclerotized and dark brown anterior margin; S6 with 2–3, S7 with 2–4 distinct setae; S8 slightly longer than epandrium, tapered posteriorly, often somewhat darker than S6 and S7 and setose in posterior half.
Genitalia. Epandrium (Figs 260, 261, 294) brown to dark brown, concolourous with or somewhat darker than pregenital sclerites in contrast to that of A. pallida, relatively long and broad (longer and wider than in A. pallida) and moderately setose, with 2 pairs of longer and thicker dorsomedial setae; also anal nssure larger and wider than in latter species. Cercus rather short and broad, with numerous nne setae, apical longest. Medandrium (Fig. 260) distinctly wider and with more projecting dorsolateral corners than in A. pallida. Gonostylus (Figs 260, 261, 263) slightly incurved, largely micropubescent on outer side and sparsely setose on inner side, as in A. pallida, but shape relatively short and oblong (not tapered and triangular), and distally with 3 distinct teeth (1 apical and 2 subapical). Hypandrium (Fig. 262) also similar to that of A. pallida, being medium-sized, relatively slender and with anterior internal lobes reduced. Transandrium (Fig. 265) simple, slightly bent medially and without caudal process as in A. pallida, but somewhat broader. Pregonite (Fig. 262) strongly resembling that of A. pallida, having a small, short, triangular process behind the larger anterior tooth-like projection, but the latter process is trapezoidal rather than subtriangular, and the posterior part of the pregonite has more (5–6) setae. Postgonite (Fig. 262) relatively robust, less widened distally compared to A. pallida, with 1 anterior setula in proximal fourth, several sensillae and blunt apex; its proximal part connected with slender basal sclerite. Dorsal internal sclerite at base of postgonite narrow but distinct. Basal membrane (Figs 262, 265) densely overgrown with pigmented and distinctly larger spines than those in A. pallida. Aedeagal part of folding apparatus with a group (larger than in A. pallida) of grain-like tubercles and usual elongate hyaline warts (Fig. 264). Connecting sclerite (Fig. 264) slender, dark-pigmented and, in contrast to that of A. pallida, terminating in a group of distinct pigmented spines. Phallapodeme (Fig. 264) relatively slender, with basal part deeply forked; fulcrum shifted close to apex as in A. pallida, but apex more projecting and wing-like laterally. Aedeagus with short phallophore (Fig. 264) and very large and long distiphallus that is bind from near its base. Saccus unusually long and proximally distinctly sclerotized as in A.pallida, but its large membranous part is armed with 4 robust dark spines. Filum slender, long and arched, very similarly constructed to that of A. pallida, but basally broader and partly micropubescent, medially curved and with membranous fringe, and distally with distinct sharp dorsal tooth and thin, curved, acutely pointed apex (Fig. 266), the latter provided with 3 subterminal spinulae. Ejacapodeme very small and pale-pigmented, with minute and pointed terminal projection (Fig. 264).
Female. Similar to male unless mentioned otherwise. Total body length 2.58–3.30 mm. Generally paler with brown markings reduced. Antenna with outer side of 1st nagellomere distinctly darkened, ochreous orange to pale brown, with only margins variably yellow. Darkened pattern on scutum and scutellum more reduced, appearing as longitudially greyish brown-and-yellow stripes, sometimes even with yellow areas prevailing. f 3 simply setulose posteroventrally. Wing measurements: length 2.42–3.41 mm, width 0.81–1.13 mm, Cs 3: Cs 4 = 0.97–1.26, rm\dm-cu: dm-cu = 2.07–2.84. Abdomen with preabdominal terga variable in colour, ranging from almost entirely yellow (only T1 with medial pale brown darkening) to proximally (T1, T2) completely pale brown to brown and distally (T3–T5) with large medial brownish areas. T2–T5 shorter and more transverse than in male. Preabdominal sterna hardly shorter than in male, similarly coloured but rather transversely suboblong than trapezoidal. S2–S3 slightly, S4–S5 distinctly transverse, S5 largest.
Postabdomen (Figs 268–270) relatively long and narrow, tapered posteriorly, telescopic, with sclerites yellow and/or (partly) brown. T6 simple, narrower than T5 (longer than in A. pallida), trapezoidal, entirely yellow or variably brown medially (Fig. 268) and with relatively short setae. S6 narrower than S5 (and less transverse compared to A. pallida), transversely suboblong, nnely setose. T7 slightly tapered posteriorly, always (in contrast to that of A. pallida) with large brown area of various length posteromedially, yellow laterally and anteriorly, setae relatively short and nne, and its sides expanded onto venter but not with anterior corners touching (Fig. 270) and not fused to S7; S7 (Fig. 270) small and narrow, widened posteriorly and nnely setose. 7th spiracle embedded in T7 far from anteroventrolateral margin (Fig. 269). 8th segment densely micropubescent laterally. T8 brown, distinctly longer than broad, anteriorly slightly tapered and deeply emarginate (Fig. 268), with nne exclinate setae and reduced micropubescence; S8 slightly shorter than T8, medially divided into 2 sclerites (together of cordate shape, Fig. 270) each with 2 longer nne setae besides short setosity and with posterior end invaginated into 8th segment. Genital chamber (uterus) with internal sclerotization well developed (Figs 272, 273) although rather pale-pigmented, formed by 2 separate pairs of nat curved sclerites (anterior pair higher, posterior pair longer, hence different from those in A. pallida, where subequal, cf. ROHÁĆEK 2006a: Figs 237, 238) and 1 anterior, slender, strongly curved annular sclerite (Fig. 273). Distal part of genital chamber often with dark secondary spine-like excrescences (Fig. 273). Ventral receptacle (Fig. 273) slender, tube-like, long, hyaline, terminally spirally twisted, proximally broader but without subbasal attenuation seen in A. pallida; accessory gland hyaline, with minute granulae on surface, borne on distally dilated and distinctly ringed duct. Spermathecae (1+1) shortly ovoid (Figs 267, 271), each with short cup-like terminal invagination (wider and shorter than in A. pallida), very nnely spinulose base and smooth surface (not nnely ringed in distal half as that of A. pallida); spermathecal duct very long, terminally without distinct cervix. T10 small, darker than in A. pallida and of subcordate shape, with 1 medial pair of long setae and very reduced micropubescence. S10 also different from that of A. pallida, elongately suboblong thus narrow and longer, nnely setulose and micropubescent. Cerci moderately sized, separated by their width (Fig. 268); with numerous nne setae, apical and dorsopreapical longest.
Discussion. This new species, Anthomyza pengellyi sp. nov., belongs to the A. pallida group as denned above. It is distinctly different from all other Nearctic relatives of the A. pallida group (see the key) and is, in fact, closest to the Palaearctic A. pallida forming with it the A. pallida (s. str.) subgroup. Their sister-species relationship is demonstrated by general resemblance (including the brown lateral side of the humeral callus) and, more importantly, by several shared synapomorphies that denne the subgroup: gonostylus shortened; pregonite with broadened anterior tooth and short posterior triangular process; saccus of distiphallus prolonged; nlum of distiphallus with characteristic subterminal tooth; and internal pairs of sclerites of female genital chamber situated as anterior and posterior (not dorsal and ventral). The most distinct differences between A. pengellyi and A. pallida can be seen in the structures of the male genitalia (shape of gonostylus, armature of basal membrane, saccus and connecting sclerite) and female postabdomen (shape and/or pigmentation of T6, S6, T7, T8, T10, structure of spermatheca, form of internal sclerites of female genital chamber) but A. pengellyi is most readily differentiated by the distinct brown to greyish brown markings on the mesonotum (largely yellow or with very faint marking in A. pallida), a brown to dark brown subscutellum and postnotum (reddish brown to ochreous in A. pallida), a brown epandrium (yellow in A. pallida), and often by pale setae that are ochreous to yellow in most specimens but ranging to black (always brown to black in A. pallida).
Etymology. This species is dedicated to the memory of Professor David Pengelly who formally introduced the junior author, as an undergraduate and graduate student, to the wonders of the insect world.
Biology. The habitat for A. pengellyi is still rather ill-denned but graminoids are the most common component. Collections have often been made from dry sites dominated by grasses to moist sites dominated by sedges and various combinations of graminoids. Dry (open disturbed) sites with grasses have included Bromus inermis, Poa compressa L., and Leymus innovatus (Beal) Pilg. in the west (Alberta: Peter Lougheed P. Pk. – 0.5 km W Little Highwood Pass, Fig. 259; ~ 26 km NW Highwood House – Mt. Lipsett pulloff; Elbow-Sheep Wildland Pk. – ~22.5 km NW Highwood House) while a much less disturbed site under Betula / Acer had a dominant graminoid component in the east (Ontario: Lake Superior Prov. Park – Crescent Lake Trail, Fig. 258). A decidedly mesic site with mostly Glyceria striata (Lam.) Hitchc. (Ontario: ~ 61 km NNW Elliot Lake – Three Lakes) was shared with A. dichroa and A. mcalpinei, while an extremely xeric sandy beach supporting the beachgrass Ammophila breviligulata Fernald (Ontario: Pancake Bay P. Pk., Fig. 546), was shared with the more numerous A. vulgaris. Additional references are made to “grass slope” and “ grasses at edge of agricultural neld” (Alberta: Dunvegan) which sound similar to the “streamside, mostly grasses ” reference (Alberta: ~ 20 km SSE Robb). More specincally, Calamagrostis sp. (probably C. canadensis) was identined in a dry site (New York: Whiteface Mt.) and C. canadensis in a wet hydro cut, either by itself or mixed with Equisetum ssuviatile (Ontario: Otter Rapids).
A mesic forested site yielded A. pengellyi from a range of “trailside graminoids, Impatiens ”, “short trail grasses ”, “trailside grasses ” and “trailside Carex ” (Ontario: Sault Ste. Marie – Sault College Outdoor Lab). The wet border of a fen habitat dominated by a mix of Carex utriculata Boott in Hook. and Poa cf. pratensis L. also yielded A. pengellyi, a site that transitioned to a sparse growth of mixed herbs and grasses (probably including P. cf. pratensis) near the roadside (Alberta: Peter Lougheed P. Pk). But a similarly dry border of a fen with sparse growth of C. utriculata, without a strong grass component, was also productive (Alberta: Peter Lougheed P. Pk. – Upper Lake Drive). Another example where graminoids were either absent or an insignincant component was of a community dominated by Eurybia and Equisetum under an aspen canopy (Ontario: Otter Rapids). The edge of a wet forest trail (Ontario: Moosonee) dominated by Equisetum, Rubus, and Cornus but with a signincant graminoid component was also a good site for A. pengellyi. The night period for A. pengellyi runs from 26 May (Alberta: Elkwater Park; Quebec: Old Chelsea) to 8–15 September (Utah: Logan Canyon).
