Male

Head. Third antennal segment long acuminate; yellow, arista black. Face silvery pollinose. Frons, upper part shining black, lower part silvery pollinose; eyes touching for distance equal to 2 times ocellar triangle (in case if two PTs eyes do not touch). Occiput, lower half silvery pollinose, upper half subshining black.

Thorax. Humeri pale brown. Mesonotum (viewed obliquely from front) and scutellum brownish pollinose, as well as thorax from the side. Scutellum with 6–8 pairs of longer pale hairs. Dorsocentral hairs well developed. Halter brown, stem paler.

Legs. Entirely yellow, all femora shining posteriorly, hind tibia curved and slightly thicker in the middle in posterior view. Tarsal segments yellow, last segment brown. Ventroapical row of 5–6 spines on mid femora; no spines on 1st and 3rd femur. Subapical (distal) spines on first four tibiae present. No anteromedial hairs on 3rd tibia. Hind trochanter with several white hairs on ventral side (as long as half width of t3 at base). Pulvilli as long as last tarsal segment.

Wing. Fourth costal section 0.9–1.3 times as long as third costal section. Cross-vein R-M at 1/3 of discal cell. Pterostigma coloured on distal 4/5. Hairs on tegula missing.

Abdomen. Viewed obliquely from front first tergite brownish pollinose, other tergites shining black, also on hind margins and on the sides. Hairs dispersed, short and weakly developed. Laterally 2–4 dark spines on first tergite. Postabdomen in dorsal view: S7, EP visible; T5 as long as ST8. Genitalia without dissection: ST8 angled on the right, no m.a, EP and SS yellow.

Genitalia. T6 with a bent process (slightly variable in shape, Fig. 36F ). Surstyli asymmetrical OS with projection; epandrium elongated, with thickening on the left side in ventral view; ST8 rather small, without m.a. ( Fig. 36B ). SES clearly visible with numerous hairs; gonopods asymmetrical, OG longer; phallic guide with membranous lobe and slightly pointed tip ( Fig. 36E ); phallus trifid, short; ejaculatory apodeme mushroom-shaped; sperm pump round, with two processes ( Fig. 36D ).

Female

As male except for the following characters. Frons, eyes separated; silver–grey pollinose on lower half, shining black on upper half. Pulvilli and claws about 1.5 times as long as last tarsal segment. Subapical distal spine very distinct. The tergites of the abdomen are more subshining black with faint brownish pollinosity.

Distribution— Kenya, Tanzania, Uganda.
