Diagnosis: Femora with thick ventral protuberance at base. Fourth costal section very short compared to third costal section. ST8 without m.a., with a visible dorsal depression. Surstyli asymmetrical, OS with a round basal lobe in dorsal view.

Other material examined: South Africa: 1♀, same data as PT from Ramsgate ( NMSA) .

Male

Head. Third antennal segment acuminate; brown. Face silvery pollinose. Frons, upper part subshining black, lower part silvery pollinose, except shining black spot in the middle; eyes touching for distance equal to 3.5 times ocellar triangle. Occiput, lower half silvery pollinose, upper half more brownish.

Thorax. Humeri pale brown. Mesonotum (viewed obliquely from front) brownish pollinose, along anterior margin slightly grey; greyish brown from the side. Scutellum brownish pollinose, with 6–7 pairs of pale hairs. Dorsocentral hairs weakly developed. Halter brown.

Legs. Trochanters and base of femora yellow brown, femora dark brown (with thick ventral protuberance at base), knees and tibiae yellow. Tarsal segments yellow, last segment brown. Ventroapical row of 6–9 short, black spines on mid femora; no spines on 1st and 3rd femur. Subapical (distal) spines on first four tibiae present. No or one anteromedial hair on 3rd tibia. Hind trochanter covered with numerous whitish hairs on ventral side. Pulvilli as long as last tarsal segment.

Wing. Fourth costal section 0.4–0.5 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. Viewed obliquely from front tergites brownish pollinose, hind margins greyish laterally, sides completely silvery pollinose. Hairs dispersed, short and weakly developed. Laterally 2–4 longer dark spines on first tergite. Postabdomen in dorsal view: S7 and edge of EP visible; T5 1.2 times as long as T8. Genitalia without dissection: ST8 dark brown, without m.a., dorsal depression visible. EP and SS yellow, SS curved.

Genitalia. Surstyli asymmetrical, OS with a round basal lobe in dorsal view, tips curved ventrally; epandrium as long as ST8; no m.a. ( Fig. 20H ). SES with numerous hairs, borders uncertain; gonopods asymmetrical, both with medial projections the inner pointed towards SS, the outer towards hypandrium; hypandrium very narrow, lobes uncertain; phallic guide triangle shaped and with strong hairs on each side in ventral view ( Fig. 20L ), pointed at tip; phallus trifid, short; ejaculatory apodeme flat, broad at tip; sperm pump round ( Fig. 20J ).

Female

As male except for the following characters. Frons, eyes separated; silver-grey pollinose except on the upper half of the frons. Fourth costal section almost as long as the third, cross-vein R-M just before middle of discal cell. First four femora with ventroapical row of 8–10 short black spines (hind femora shining posteriorly). Pulvilli and claws about 2 times as long as last tarsal segment. Female ovipositor as in Fig. 39Q .

Remarks —The female may belong to a different species, therefore it is not included in the type series.

Distribution — South Africa.

Etymology —The name refers to the special shape of the hind femora.
