Description. Male. Total body length 2.06–2.54 mm; general colour as in A. furvifrons but more densely and paler grey microtomentose (Fig. 520). Head more elongate than in all relatives, distinctly longer than high (Figs 520, 547), subquadrangular, with face strongly receding in pronle and frons projecting in front of eye (Fig. 520), dark brown and yellow. Occiput dorsomedially slightly but distinctly concave, dark brown to black with distinct greyish microtomentum. Frons relatively narrow (Figs 521, 550), longer than in relatives, medially dull blackish brown (at most up to anterior third of frons), only frontal triangle dark grey microtomentose; anterior third or more of frons orange-yellow; orbits largely yellow and silvery white microtomentose, more posteriorly (behind posterior ors) gradually brownishdarkened and with silvery grey microtomentum. Frontal triangle narrow, reaching at most to midpoint of frons. Frontal lunule yellow, whitish microtomentose. Face, parafacialia and gena yellow to orange-yellow and mostly dull. Face very narrow, medially weakly sclerotized, more or less furrowed and somewhat darkened. Parafacialia relatively broad and (like gena) with silvery white microtomentum (most dense on vibrissal angle). Both parafacialia and gena with rather broad but relatively pale (dark yellow to ochreous) marginal stripe. Postgena ventrally yellow and whitish microtomentose, dorsally brown and greyish microtomentose merging with similar vestiture on occiput (Fig. 520). Mouthparts (including palpi) similarly coloured to those of A. furvifrons.

Other pedal chaetotaxies as described for A. furvifrons. Wing (Fig. 525) long and narrow (usually slightly narrower than those of relatives), with pale brown veins and hyaline unicolourous (ochreous to brownish) membrane. Wing venation mostly as in A. furvifrons only R 4+5 usually very slightly bent (recurved) and running closer to M. Discal (dm) cell often narrower and less widened distally, with r-m situated somewhat in front of the middle of dm cell. Apical portion of CuA 1 usually longer than dm-cu and alula narrower.

Preabdominal sterna lighter than those of A. furvifrons, pale ochreous yellow, only S1, S2 (darkest) and S5 (partly, laterally) brownish. T6 yet larger (longer) than in A. furvifrons, usually more than half length of T5, largely brown but with a narrow unpigmented area anteromedially or medially across sclerite (hence sometimes seemingly divided into two sclerites), often with a few setae at posterior margin. S6 (paler) and S7 (darker) brown, both with more sclerotized and blackish brown anterior margin, each with 2 (rarely 3) setae; S8 as in A. furvifrons.
Genitalia most similar to those of A. equiseti. Epandrium (Figs 551, 552) about as broad as high thus slightly higher than that of A. equiseti, blackish brown and somewhat more densely setose than in latter species, with 1 dorsolateral pair of (not much) longer and thicker setae; anal nssure distinctly narrower (Fig. 551) than in A. equiseti. Cercus moderately narrow, with apex more or less pointed; setae nne and numerous, the longest apical slightly longer than subapical. Medandrium (Figs 551) wider and not as high as that of A. furvifrons, in pronle somewhat constricted in the middle (Fig. 552), dorsolateral corners small. Gonostylus (Figs 551, 552, 559, 563) small, most similar to that of A. equiseti thus moderately bent medially, with simple acute apex, micropubescence on most of outer side and setae on inner side of both anterior (there more than in A. equiseti) and posterior margins (Figs 559, 563) but somewhat more elongate and with anterior margin more concave than in the latter species. Hypandrium (Fig. 553) relatively elongate, with anterior internal lobes reduced, membranous; its posterior arms nrmly fused with transandrium. Transandrium (Fig. 554) relatively strong and well sclerotized, posteromedially with broad, nat but dorsomedially weakly sclerotized caudal process terminating in distinctive trough-like appendage (Figs 553–555, 561). This appendage smaller and narrower than in A. equiseti and with teeth on ventrolateral margins reduced or absent (Figs 553, 561), only those on posterior corners (Figs 554, 555) well developed. Pregonite (Figs 553, 560) with anterior part angularly projecting medioventrally (this process distinctly larger than in A. equiseti) and bearing 3 setae (as in relatives), 1 long, 1 shorter and 1 minute; posterior part of pregonite reduced and hairless. Postgonite (Fig. 553) slender, more elongate and bent than that of A. equiseti, with moderately pointed apex and 1 anterior setula in distal fourth in addition to granular sensillae; its proximal part attached to large basal sclerite provided with several (5–8) ventral spines. Armature of basal membrane incorporated into ventral appendage of caudal process of transandrium. Aedeagal part of folding apparatus with similarly spinose walls as those of A. equiseti: right wall dorsally with a large cluster of strong dark spines, ventrally with only a number of spine-like tubercles (Fig. 558); left wall with only 2–3 long and dark spines in dorsal cluster, ventrally there are only smaller spines and tubercles (Fig. 556). Connecting sclerite slender, only dorsally dilated and with granulous structure, well sclerotized on apex armed with 1–2 dark spines surrounded by a few pale tubercles (Fig. 556). Phallapodeme slender with basal part dilated and deeply forked, fulcrum rather long but relatively slender, apex with small lateroventral corners. Aedeagus with short, frame-like phallophore fused to distiphallus as in relatives. Distiphallus basally with dorsal and ventral elongate sclerites; bind from about two-nfths. Saccus proximally well sclerotized (more on right side, Fig. 556) and its dilated distal membranous part provided with rather variable armature of 2 (Fig. 562) to 4 robust black spines (Fig. 556). Filum formed by single sclerite, only partly pigmented, very nnely spinulose in proximal and middle part, subterminally only somewhat widened without corner or projection, with terminal part slender; apical part gradually tapered into sinuate, very slender and acute point with 3–4 spinulae (Fig. 557). Ejacapodeme small, slender and pale, with elongate digitiform projection (Fig. 556).
Female. Similar to male unless mentioned otherwise. Total body length 2.26–3.18 mm. Antenna with 1st nagellomere anterodorsally (on both sides) more or less extensively ochreous to brownish-darkened (Figs 545, 547), sometimes leaving only narrow proximal and ventral parts yellow. Palpus usually darkened to brown or grey apically. Marginal stripe of parafacialia and particularly gena darker ochreous to brown. Yellow areas on thoracic sternal midline and propleuron more common and more extensive in some populations, and may include margins of the humerus and margins and isolated spots on the mesopleuron. Wing measurements: length 2.46–3.26 mm, width 0.69–1.02 mm, Cs 3: Cs 4 = 1.23–1.47, rm\dm-cu: dm-cu = 2.25–3.27. Abdomen (Fig. 547) similarly formed, coloured and setose to that of A. furvifrons but T3–T5 not longer than T2, subequal in length but T4 slightly wider than T3 or T5. Preabdominal sterna S2–S5 somewhat narrower than in male; only S1 (wider than long) and S2 (as long as wide) brownish, S3–S5 (and S6) light ochreous yellow. S2–S4 becoming only slightly larger and wider posteriorly, S3–S5 as long as broad or slightly longer than broad, S5 usually narrower than S4.
Postabdomen (Figs 566–568) closely resembling that of A. equiseti, elongate, slender, gradually tapered posteriorly. T6 large, broad but narrower than T5, brown with posterior margin more or less extensively unpigmented, setose in posterior three-fourths. S6 slightly transverse, wider posteriorly, with anterior corners rounded, pale ochreous thus lighter than in A. equiseti, setose in posterior half. Tergosternum T7+S7 conically ring-shaped, blackish brown laterally (Figs 564, 566) and dorsally with narrow posteromedial incision (Fig. 567). Ventral part of T7+S7 with relatively large desclerotized area (Figs 565, 568) anteriorly delimited by short transverse (longitudinally grooved, see Figs 565, 570, arrows), pale brown strip connecting both blackish brown lateral parts of synsclerite (both yellowish brown in palest specimens); the groove often producing a chordate anterior margin to the membranous area. The ventral part of T7+S7 differing from that of A. equiseti in having desclerotized area with more setae and, particularly, in lacking narrow yellowish brown anterolateral areas reaching above 7th spiracle. Posterior to the ventral desclerotized area there is an additional pale brown, nat and distinctively micropubescent posteromedial appendage (Figs 564–566, 568, 570, often at least partly invaginated) shared with A. equiseti. 8th segment (Figs 566, 568), narrow, long, largely membranous, micropubescent. T8 narrow, elongate, posteriorly parallel-sided, with nne exclinate lateral setulae and anterior corners laterally wing-like dilated and separated by a deep narrow incision (Fig. 567); S8 (Fig. 568) much shorter than T8, medially divided to form 2 narrow, nnely setose sclerites with posterior end curved and invaginated (as in relatives). Genital chamber (uterus) with internal sclerotization (Figs 571, 573) formed by 1 pair of long, nat, but rather crooked and complex sclerites with suboblong pronle (cf. Fig. 571, in contrast to a more regularly oblong outline in A. equiseti) and 1 anterior annular sclerite that is wider anteriorly and posteriorly, down-curved posteriorly (usually more than in A. equiseti). Ventral receptacle (Fig. 571) very long, slender, tubuliform, hyaline and multiply twisted, distinctly longer than that of A. equiseti; accessory gland hyaline, elongate, with duct slightly dilated distally. Spermathecae (1+1) suboval, with long digitiform invagination (Figs 569, 572), indistinctly wrinkled surface and dark spinulae (more than in A. equiseti) near duct insertion; the latter situated close to opening of invagination; duct ending in very short, pigmented cervix. T10 (Fig. 567) small, dark, transversely oval, with 2–4 pairs of setae including 1 long pair and with sparse micropubescence. S10 (Fig. 568) small, longer than T10, somewhat tapered and rounded anteriorly, wider posteriorly, nnely setulose and micropubescent. Cercus slender, relatively long, with numerous nne setae, apical and dorsopreapical longest, subequal in length (Figs 566–568).
Discussion. Based on a number of shared male and female genitalic characters, A. vulgaris sp. nov. is considered the sister species of A. equiseti sp. nov. Most of the male genitalic features are probably plesiomorphic (e.g. medandrium wider and more robust; gonostylus with simple apex; aedeagal part of folding apparatus without long spines ventrally) but the unique posteromedial ventral appendage of the female T7+S7 (see Figs 564, 565, 570, 589, 591) is considered a strong synapomorphy of this sister pair.
It is notable that A. vulgaris is variable in some structures of the male genitalia, particularly the form of the gonostylus (Figs 559, 563), the armature of the caudal process of the transandrium (cf. Figs 553, 561) and the number of spines in the saccus (Figs 556, 562), which ranges from two to four. This variability may renect the extreme habitat and host-plant tolerance of A. vulgaris (see below) but this assumption should be experimentally tested. Nevertheless, A. vulgaris differs from all Nearctic species of the A. gracilis group in having lighter microtomentum of the thorax and a distinctly elongate head and eye. There are also a number of differences from its closest relative, A. equiseti, not only in the terminalia (epandrium narrower, pregonite more projecting, postgonite more slender, ventral appendage of caudal process with teeth reduced, saccus with fewer spines, female T7+S7 with paler anteroventral strip simple (not extended to 7th spiracle), female T8 with anterolateral wing-like dilations), but also in the form of the head (see above), the colouration of the frons and, particularly, the legs (in A. vulgaris uniformly yellow except for the sometimes shiny brown patch on the base of cx 1 and the 2 brownish terminal tarsal segments).
Etymology. The new species is named vulgaris (= common, a Latin adjective) to renect its frequent occurrence in various communities of graminoid plants.
Biology. The habitat of Anthomyza vulgaris includes a wide range of sites from extremely dry to relatively wet sites with plant communities usually dominated by grasses. In at least Ontario, A. vulgaris is one of the most commonly encountered anthomyzids, particularly in open, disturbed grassy areas.
The driest sites include those collections made from the beach grass Ammophila breviligulata Fernald from three localities, namely Nova Scotia: South Harbour Beach – mixed with Lathyrus sp. (Fabaceae) not considered a potential host; Ontario: Pancake Bay P. Pk., Fig. 546; and Quebec: Îles de la Madeleine, road 199 between Havre-aux-Maisons and Point-aux Loups. There are also similar records from a very sandy site (Ontario: Bruce Peninsula N. P.–Singing Sands) supporting Calamagrostis and “ Agropyron ” (likely Elymus repens) and from “dunes” (Nova Scotia: Crescent Beach; Ontario: Manitoulin Island–Sand Bay; Quebec: Godbout). An unusual sandy site was the exposed perimeter of a drained man-made lake (Ontario: ~ 66 km NNW Elliot Lake, Rocky Island Lake) where Scirpus microcarpus grew in isolated clumps (Fig. 548).
Multiple collections made from prairie habitat in Manitoba (Aweme), including tallgrass prairie (Gardenton, Winnipeg) and “ Andropogon-Stipa prairie community” (5 mi SW Shilo), also suggest dry habitats, as does the collection from Andropogon (Wisconsin: Swan Lake– 4 mi E Portage).A particular reference to “tundra at summit” (New Hampshire: Mt. Washington) may be another dry site.
There are several records indicating that roadsides and both dry and wet ditches yield this species. Fens, alvars (e.g. Ontario: Manitoulin Is., nr. Misery Bay [Prov.] Nature Reserve, Little Lake Huron Road, Fig. 549), and alvar savanna are also recorded, along with riparian habitats such as “shoreline” and “riverside”, along with “lakeside” and “marshy lake shore”. References such as “vegetation on boggy trail”, “noodplain community near tamarack bog”, “boggy meadow” and “ Sphagnum bog” also indicate that wetter sites can support populations of this species.
Observations at one roadside ditch site supporting all three species of the A. gracilis group (Ontario: ~ 21 km NNE Smooth Rock Falls; discussed under A. furvifrons) suggest that A. vulgaris was more commonly collected on the drier slopes of the roadside ditch in a mix of grasses and herbs, though dennitive segregation among the three species could not be made. There are a few specimens recorded from Equisetum ssuviatile, but this host plant for A. equiseti is likely not a host for A. vulgaris and the specimens were likely part of a population emerged from nearby grasses. For example, the Marathon, Ontario site yielded large numbers of A. equiseti from mostly emergent E. ssuviatile, and the only specimens of A. vulgaris were taken about 50 meters away on the other side of the highway among roadside graminoids (mostly grasses).
Specinc graminoid plants that are mentioned include grasses (Calamagrostis, Phalaris, “ Agropyron ” (likely E. repens )), sedges (Carex, Dulichium, Eleocharis, Scirpus) and rushes (Juncus). Cattails (Typha) are not likely to be a host but indicate a wetter site. Collections that do not include grasses tend to be represented by small numbers of specimens. Unusual references include “ex. Ulmus sp.”, “ex. Betula glandulosa ” Michx., and “ex. leafy spurge ” (Euphorbia esula L.) but these are not considered likely hosts.A collection from the blossoms of Smilacina sp. suggests a pollen and nectar source for adults (North Carolina: Mollie Gap). Adults of A. vulgaris have been collected from 23 May (Tennessee: SW corner of Cades Cove) to 4 September (Ontario: Hilton Township).
Distribution. Anthomyza vulgaris ranges transcontinentally from British Columbia to Prince Edward Island (Alberta, British Columbia, Labrador, Manitoba, New Brunswick, Nova Scotia, Ontario, Prince Edward Island, Quebec and Saskatchewan) in Canada. However, in the United States of America, this most commonly collected species of the Anthomyza gracilis group is restricted to the east from Minnesota to Maine and Pennsylvania to Tennessee and Georgia (Georgia, Maine, Massachusetts, Michigan, Minnesota, New Hampshire, New York, North Carolina, Pennsylvania, Tennessee, Vermont, West Virginia and Wisconsin) (see Table 2).
