Diagnosis. Hyaline part of cell r1 nearly semicircular. Abdominal tergites 4 and 7 with white hairs. Epiphallus subquadrate, but slightly wider at middle; distiphallus rather short with an obtuse tip in dorsal view, and with acute tip curved apically in lateral view.
Description. Male. Body length 9 mm, wing length 9 mm.
Head black with gray pollen; ocellar tubercle reddish brown. Hairs on head mostly black; frons with dense long black hairs; face with dense black hairs; occiput with sparse black hairs, and a row of erect brown hairs on the edge; ocellar tubercle with seven long black hairs. Antenna yellowish brown; scape long cylindrical, two times longer than wide, with rows of long black hairs on both sides; pedicel nearly as long as wide, with sparse black hairs; first flagellomere onion-shaped, bare. Antennal ratio: 5:2:8. Proboscis yellowish brown with short yellow hairs; palpus brown with black hairs.
Thorax black with brown pollen. Hairs on thorax black and yellow, bristles black; postpronotal lobe with black long hairs, mesonotum with row of yellow long hairs at anterior margin and three long black lateral bristles near base of wing; postalar callus with three black bristles. Scutellum with long black hairs and sparse short yellow hairs. Legs brown except tarsi and hind tibia black. Hairs and bristles on legs black. Femora with black hairs; tibiae with bristle-like hairs; tarsi with some short black hairs. Mid femur with three av apically; hind femur with four av apically. Mid tibia with five ad, seven pd, six av and six pv; hind tibia with 12 ad, 11 pd, nine av and seven pv. Wing (Fig. 10) half infuscate; hyaline part including entire cells r4 and m1, most part of cells r2+3, r5, m2, cu-a1, and dm, and little part of cells r1, cup, and a; hyaline part of cell r1 nearly semicircular. Halteres brown; knob pale.
Abdomen black with grey pollen. Hairs on abdomen white and black; dorsum with long dense black hairs laterally except tergites 4 and 7 with white hairs; dorsum with black hairs, tergites 4 and 7 with white hairs; tergites 9–10 with black hairs. Sternites with brown recumbent hairs and black erect hairs.
Male genitalia (Figs. 65–70). Epandrium subquadrate, distinctly longer than high, and with distinct lateral extension at base in lateral view, epandrium slightly higher than wide in posterior view; gonocoxa with slightly narrow apical portion, with a narrow middle incision apically and apicolateral lobes somewhat acute apically in ventral view; gonostylus with a basal process, its acute tip strongly curved in lateral view; epiphallus nearly quadrate, but slightly wider at middle, distiphallus rather short with an obtuse tip in dorsal view, and with its acute tip curved apically in lateral view.
Female. Body length 8 mm, wing length 9 mm. Similar to male, but abdominal tergite 1 with white hairs, tergites 2–7 with black hairs.
