Description.

Wing length 2.1-2.9 mm (♂), 2.5-3.5 mm (♀). Length of ultimate section of vein M4 divided by penultimate section: 0.6-0.8. Eye height divided by gena height: 3.6-5.6. First flagellomere relatively elongate with dorsoapical corner slightly pointed; velvety with small apical tuft of dense pale hairs (only distinct when viewed anteriorly). Fronto-orbital plate and parafacial slightly pronounced, curving under eye as cheek. Ocellar triangle reaching level of anterior ors, sides concave.

Chaetotaxy: Two ors, two or three ori (if three, anterior seta smaller). Four postsutural dorsocentrals, anterior two much shorter. Mid tibia with two posteromedial setae.

Colouration: Body black with halter white and wing veins paler and fore knee sometimes very narrowly yellow. Calypter margin and hairs white. Faint greenish shine sometimes evident, mostly on abdomen.

Genitalia: (Figs 143-146 ) Surstylus broad and triangular, entirely fused to epandrium, margin darkly pigmented, setae clustered at apex and inner margin with several medial to subapical tubercle-like setae. Inner lobe of hypandrium with furrows leading to base of setae. Postgonite small, flat, lobe-like. Halves of basiphallus converging to point of fusion at base; apices abruptly converging; right 1/2 with long membranous extension at midpoint. Distiphallus of " Agromyza nigripes -type" (capsule-shaped with subbasal opening for entry of ejaculatory duct, pronounced dorsobasal collar, and medial convolution), with sides parallel medially, one pair of elongate parallel dark ventromedial swellings, and a slightly broadened apical margin with inner surface minutely spinulose; slightly angled dorsally.
