Male

Head. Third antennal segment acuminate; brown. Face silvery pollinose. Frons, upper part subshining black, lower part silvery pollinose; eyes touching for distance equal to 3.5 times ocellar triangle. Occiput, lower half silvery pollinose, upper half subshining black.

Thorax. Humeri yellow-brown. Mesonotum (viewed obliquely from front) subshining black, along anterior margin slightly silvery; completely grey from the side. Scutellum brownish pollinose, without hairs. Dorsocentral hairs weakly developed. Halter yellowish brown.

Legs. Trochanters and femora black (1st four femora silvery pollinose, hind femur shining posteriorly), knees and tibiae yellow. Tarsal segments yellow, last segment brown. Ventroapical row of 6–8 pairs of short black spines on first four femora; 6 pairs of longer spines on 3rd femur. Subapical (distal) spines on first four tibiae missing. No anteromedial hairs on 3rd tibia. Hind trochanter with 2 dark hairs on ventral side, otherwise shining. Pulvilli shorter than last tarsal segment.

Wing. Fourth costal section 0.8 times as long as third costal section. Cross-vein R-M beyond 1/3 of discal cell. Pterostigma fully coloured. Hairs on tegula missing.

Abdomen (already dissected). Hairs dispersed, short and weakly developed. Laterally 4–5 dark spines on first tergite. Postabdomen in dorsal view: (T6, S7, EP) visible.

Genitalia. Surstyli asymmetrical, OS larger, both broader distally in lateral view; ST8 large, m.a. 2/3 as wide as ST8 ( Fig. 15B ). SES uncertain; gonopods hairy, equally long, OG slimmer; phallic guide broad, sides parallel, with three pointed tips in ventral view ( Fig. 15F ), slightly bent in lateral view ( Fig. 15A ); phallus trifid, at least one branch covered with minute hairs; ejaculatory apodeme linear, broader towards tip; sperm pump round ( Fig. 15E ).
