Male

Head. Third antennal segment acuminate; yellow. Face silvery pollinose. Frons, lower part greyish pollinose; eyes touching for distance equal to 2 times ocellar triangle. Occiput greyish pollinose.

Thorax. Humeri brown. Mesonotum (viewed obliquely from front) black with brownish pollinosity; also from the side. Scutellum same as mesonotum, with short and weak hairs. Dorsocentral hairs weakly developed. Halter brown.

Legs. Trochanters and femora, knees, tibiae, tarsal segments yellow, last segment brown. Ventroapical row of 4–6 very small setae on first four femora; no spines on 3rd femur. Subapical (distal) spines on first four tibiae present. No anteromedial hairs on 3rd tibia. Hind trochanter without hairs or spines on ventral side. Pulvilli somewhat shorter than last tarsal segment.

Wing. Fourth costal section 0.8 times as long as third costal section. Cross-vein R-M at 1/3 of discal cell. Pterostigma fully coloured. One small hair present on tegula.

Abdomen. Viewed obliquely from front tergites black with brownish pollinosity, sides with occasional grey patches. Hairs dispersed, short and weakly developed. Lateral spines on first tergite: 1–3 dark hairs. Postabdomen in dorsal view: T5 as long as ST8. Genitalia without dissection: moderately swollen, EP and SS yellow, m.a. elongated, on the right side of ST8 (narrower than half with of ST8).

Genitalia. Surstyli asymmetrical, OS with long projection on inner surface (probably broken on the HT drawn); epandrium long compared to ST8 ( Fig. 22B ). SES present, with ca. 10 dispersed hairs; gonopods asymmetrical, OG longer; hypandrium connected to EP; phallic guide thick, distally pointing towards SS, membranous lobes at tip; phallus trifid, as long as ST8+EP+SS ( Fig. 22F ); ejaculatory apodeme mushroom-shaped, with membranous lobe; sperm pump with 2 distal projections ( Fig. 22D ). IS in lateral view bent ventrally, with pale, sclerotized lobe on outer edge ( Fig. 22C ).

Female

Ovipositor as in Figs 40R–S .

Remarks —The process on the OS of the HT may have been broken since most of the other specimens studied have longer structure.

Distribution— Democratic Republic of Congo, Kenya, South Africa.
