Description.

Wing length 1.3-2.0 mm (♂), 1.4-1.8 mm (♀). Length of ultimate section of vein M4 divided by penultimate section: 1.7-3.5. Eye height divided by gena height: 3.0-4.2, sometimes up to 5.1 in Canadian specimens. Scutum lightly dusted with pruinosity.

Chaetotaxy: Two ori (anterior seta small to absent); two ors. Acrostichal setulae in two rows (sometimes three anteriorly).

Colouration: Head yellow with posterolateral margin of frons lateral to (and not touching) vertical setae yellow to brown; back of head brown dorsally; ocellar tubercle brown; clypeus brown to light brown with centre yellow. Scutum with complete lateral yellow stripe broadly overlapping margin of scutellum. Scutellum yellow with lateral corner brown. Katatergite yellow; anatergite sometimes brownish ventrally; mediotergite dark brown. Pleuron yellow with large spot on katepisternum and meron, and with small (sometimes very faint to indistinct) anteroventral spot on anepisternum and anepimeron; anepimeron sometimes brown mottled. Calypter margin brownish. Legs yellow with fore tibia and tarsi brownish, mid and hind tarsi brown, and mid and hind tibiae brown at base, apex and on dorsal surface; material from western United States with tibiae yellow with dorsum faintly brown (paler to entirely yellow on anterior legs) and tarsi only brownish on distal three segments; femora of Canadian specimens sometimes with pale dorsal streaking or with brown dorsobasal spot. Abdomen yellow with dorsum, epandrium and surstylus brown. Variation in Canadian material discussed in Lonsdale (2017).

Genitalia: (Figs 603-607 View Figures 599–607 ) Epandrium with one posterodistal spine. Surstylus darkly pigmented with one large and one small subapical spine. Inner surface of epandrium with one pair of dark bars with apical spine. Basiphallus broadly sclerotised along left lateral and dorsal surfaces. Swollen apical section of ejaculatory duct short, wide, and narrowed apically. Hypophallus relatively short with long apical hairs. Paraphallus absent. Mesophallus narrow, cylindrical, and fused to distiphallus; mesophallus and distiphallus with ventral suture. Distiphallus large, weakly pigmented, bowl-shaped with minute internal reticulations and spinules, angled dorsally, slightly bilobed, elongate, and with one pair of short, wide membranous tubules. Ejaculatory apodeme well-developed and dark with base of duct lightly sclerotised, stem narrow and blade large and thickened along margin; sclerite on sperm pump broad, dark, with thick margin.
