Male
Head. Third antennal segment yellow; acuminate. Face silvery pollinose. Frons, upper part shining black, lower part silvery pollinose (except narrow black median line); eyes touching for distance equal to 2.5 times ocellar triangle. Occiput, lower half silvery pollinose, upper half less so.
Thorax. Humeri pale brown. Mesonotum (viewed obliquely from front) brownish pollinose; silvery from the side. Scutellum brownish pollinose, 3–4 pairs of pale, short hairs. Dorsocentral hairs distinct. Halter yellow-brown.
Legs. Trochanters and base of femora yellow-brown, femora brown (pv f1,2 silvery pollinose, f3 shining brown), knees, tibiae and tarsal segments yellow, last segment brown-black. Ventroapical row of 2–3(-6) very short dark spines on first femora; 5–8 spines on f2; 4–5 longer spines on 3rd femur. Subapical (distal) spines on first four tibiae present (short). No anteromedial hairs on 3rd tibia. Hind trochanter with two to six pale hairs on ventral side as long as basal width of tibia. Pulvilli as long as last tarsal segment.
Wing. Fourth costal section 1.4–1.7 times as long as third costal section. Cross-vein R-M just beyond 1/3 of discal cell. Pterostigma fully coloured. Hairs on tegula absent.
Abdomen. Viewed obliquely from front tergites completely silvery-golden pollinose (may be brown with slightly silver pollinosity). Minute pale hairs occasionally. 1–4 dark lateral spines on first tergite. Postabdomen in dorsal view: T6 visible (sometimes S7 as well); T5 0.8–1 times as long as ST8. Genitalia without dissection: black, SS+EP yellowish, ST8 with dorsal groove on the right side, m.a. small, round (sometimes elliptic) and ventrally oriented.
Genitalia. Surstyli asymmetrical, with 6–8 hairs ventrally; ST8 slightly enlarged (Fig. 27B). SES distinct; gonopods asymmetrical, OG longer, IG with pointed tip; lobes of hypandrium slightly turned; phallic guide with hook-like projection on the right in ventral view (Fig. 27F); phallus trifid, short and bent in 90°; ejaculatory apodeme flat, mushroom-shaped; sperm pump oval, with two projections (Fig. 27D).
Female
As male except for the following characters. Frons, eyes separated; silver-grey pollinose except in front of ocellar triangle for length equal to 0.5 times ocellar triangle. Third antennal segment more distinctly pointed than in males. Pulvilli and claws about 2–2.5 times as long as last tarsal segment. Fourth costal section 1.2–1.5 times as long as third costal section. Female ovipositor (Figs 39F, P): piercer curved.
Remarks — Skevington (2003) designated a neotype for this species from South Africa ("Natal, Weenen, [28°51' S, 30°04' E, 866 m], 2840 ft., in thorn country, vii–viii. 1923, H.P. THOMASSET, Pres. by Com. Inst. Ent. B. M. 1948-198, #4489 (BMNH)"), which has not been studied. This species has a projection next to the trifid phallus similar as in E. rubrus, which might be related to this species. The species can be recognised by the dorsal groove on the ST8 and the coloration of the legs, and after dissection of males the pointed tip of the IG is very distinct.
Distribution— Botswana, Burundi, Comoro Islands, Japan, Kenya, Madagascar, Micronesia, Namibia, Nepal, Solomon Islands, South Africa, Uganda, Zimbabwe.
