Male

Head. Third antennal segment long acuminate; yellow-brown. Face silvery pollinose. Frons, upper part shining black, lower part silvery pollinose, except tiny black spot; eyes touching for distance equal to 2.5–3 times ocellar triangle. Occiput, lower half silvery pollinose, upper half less so.

Thorax. Humeri pale brown. Mesonotum (viewed obliquely from front) black with brownish pollinosity, along anterior margin more greyish; from the side greyish pollinose. Scutellum black with brownish-grey pollinosity, 3– 4 pairs of distinct, short, pale hairs. Dorsocentral hairs uncertain. Halter brown, stem darker.

Legs. Trochanters and femora dark brown (pv surface of f3 shining), knees, tibiae and tarsal segments yellowbrown, last segment dark brown. Ventroapical row of minute dark hairs, mainly on f2; pv some white hairs along f3. Subapical (distal) spines on first four tibiae distinct. One distinct anteromedial hair on 3rd tibia. Hind trochanter with fine, pale hairs on ventral side. Pulvilli equal to last tarsal segment.

Wing. Fourth costal section 0.85 times as long as third costal section. Cross-vein R-M beyond 2/5 of discal cell. Pterostigma fully coloured. Hairs on tegula uncertain.

Abdomen. Viewed obliquely from front the ground colour is brown with greyish pollinosity, T2 sometimes brownish. Hairs on abdomen very few and short; 1–3 dark lateral bristles on first tergite. Postabdomen in dorsal view: edge of S7 visible; T5 1.8–2 times as long as ST8. Genitalia without dissection: brown in general, no m.a.

Genitalia. Surstyli very broad at base, with hairs as long as SS in the middle, projections at base ventrally, tip of SS hooked; epandrium roundish around cerci, otherwise rectangular at distal end; no membranous area ( Fig. 35L ). SES very distinct, with 12–15 hairs ventrally, strongly connected to SS; gonopods asymmetrical, OG is broader; hypandrium elongated, not connected to EP ( Fig. 35H ); phallic guide with three hook-like projections at tip in ventral view ( Fig. 35M ), with tooth-like projection towards SS ( Fig. 35G ); phallus coiled; ejaculatory apodeme 3- sided (with 3 lobes); sperm pump oval base with 3 projections ( Fig. 35J ); phallic sheath possibly present ( Fig. 35N ), may be damaged on specimen from Natal.

Female—Unknown.

Distribution— Botswana, Namibia, South Africa.
