Male

Head. Third antennal segment acute; brown [based on PT]. Face greyish pollinose. Frons, lower part greyish pollinose on the sides, black in the middle; eyes touching for distance equal to 4.5-5 times ocellar triangle. Occiput, upper half brownish pollinose, lower half grey.

Thorax. Humeri light brown. Mesonotum (viewed obliquely from front) brownish pollinose; greyish from the side. Scutellum brownish pollinose, with short, pale brown hairs. Dorsocentral hairs weakly developed. Halter, knob dark brown, stem paler.

Legs. Trochanters and base of femora brown, femora black, knees, tibiae, tarsal segments, pale brown [no t3 on types], last segment black. Ventroapical row of 4–5 very small spines on f1; 10–12 short, stout on f2; no spines on 3rd femur. Subapical (distal) spines on first four tibiae missing. Anteromedial hairs on 3rd tibia [no 3. leg on types]. Hind trochanter with minute white hairs on ventral side. Pulvilli slightly smaller than last tarsal segment.

Wing. Long, compared to body, damaged on types. Fourth costal section (probably) equal to third costal section. Cross-vein R-M almost in the middle of discal cell [PT: just beyond 1/3, near basal 2/ 5 in original description], dm elongated. Pterostigma fully coloured. Hairs on tegula missing.

Abdomen. [dissected in HT] Hairs dispersed, short and weakly developed. Seven dark, strong bristles laterally on first tergite. Postabdomen in dorsal view [dissected]: (T6, S7, EP) visible.

Genitalia (damaged on HT, lost on PT). Surstyli both broken, but not fused with EP ( Fig. 16H ), inner surstylus with a projection at base ventrally; epandrium deformed; ST 8 m. a. not visible ( Fig. 16J ) cf. Hardy 1959 b. SES with 20– 22 tiny spines, lower border distinct; gonopods not clear, probably very small; hypandrium not connected to EP; phallic guide broadening in the middle, pointed at apex ( Figs 16K, G ); phallus with membranes, short, trifid, branches curved; ejaculatory apodeme elongated, linear; sperm pump oval.
