(Figs 33A–F, 39B, 40K)
Dorilas (Eudorylas) setiformis Hardy 1949 a: 55.
Diagnosis: Third antennal segment very long acuminate. Legs completely yellow, one anteromedial hair on t3 present (on all tibiae in case of the female). Phallic guide broad towards tip, with hairy protuberances at base; phallus trifid, very long (at least two times as long as postabdomen) and coiled, branches narrow and stick together; ejaculatory apodeme with three lobes, enlarged; part of the ejaculatory duct is coiled as a spiral.
Type material: Malawi: 1♀, HT, Mt Mlanje, Nyasaland, 25.XI.1912, S.A. Neave; Pres by Comm. Inst. Ent. BM 1953-357 (BMNH).
Other material examined: Tanzania: 1♂, 1♀, East Usambara, Amani, 1000m, 22.i.1977, Zool. Mus., Copenhagen, H. Enghoff, O. Lomholdt, O.Martin leg. (both ZMUC). Zimbabwe: 1♂, N. Vumba, S. Rhodesia, 17.3.1966, D. Cookson (NMSA).
Male
Head. Third antennal segment very long acuminate, setiform (hair-like part slightly longer than other part); yellow, elongated part and arista brown-black. Face silvery pollinose. Frons shining black on upper half, silvery pollinose on lower half. Occiput faintly greyish pollinose.
Thorax. Humeri yellow. Mesonotum (viewed obliquely from front) golden yellow pollinose; silvery from the side. Scutellum yellowish with silver pollinosity, with 10–12 pairs of short, pale hairs. Dorsocentral hairs very weakly developed. Halter yellow-brown, stem white.
Legs. Completely yellow, last tarsal segments brown. Ventroapical row of 6 short, black setae on f1, 16–20 on f2; and 2–4 smaller spines on 3rd femur. Subapical (distal) spines on first four tibiae, and one anteromedial hair on t3 present. Hind trochanter silvery pollinose with 2–3 pale hairs on ventral side. Pulvilli as long as last tarsal segment.
Wing. Fourth costal section 1.4–1.5 times as long as third costal section. Cross-vein R-M beyond 2/5 of discal cell. Pterostigma fully coloured. Two-three brown hairs on tegula are present.
Abdomen. Viewed obliquely from front tergites golden-yellow pollinose, sides greyish. Hairs dispersed, distinct and whitish. Laterally 1–2 dark spines on first tergite. Postabdomen in dorsal view: edge of S7 visible; T5 2 times as long as ST8. Genitalia without dissection: M.a. round, as wide as 1/3 of the width of the black ST8, SS and EP paler.
Genitalia. Surstyli subsymmetrical, broadening distally, with teeth-like projections in lateral view; cerci bulging in lateral view; epandrium wider than long; ST8 enlarged, m.a. small, rounded (Fig. 33B). SES uncertain; gonopods symmetrical; hypandrial lobes short; phallic guide broad towards tip, with hairy protuberances at base; phallus trifid, very long (at least two times as long as postabdomen) and coiled, branches narrow and stick together (Fig. 33D); ejaculatory apodeme with three lobes, enlarged; sperm pump cup-shaped, round; part of the ejaculatory duct is coiled as a spiral (Fig. 33F).
Female
As male except for the following characters. Frons narrow (1.5–2 times as wide as first ocellus), shining black in front of ocellar triangle, otherwise silvery pollinose (black median line may be present on upper half). Ventroapical row of 4–6 tiny, dark setae on f1,2 and no spines on f3. One anteromedial hair on all tibiae. Pulvilli and claws 2–2.5 times longer than last tarsal segment. Cross-vein R-M just before middle of discal cell. Tergites completely silvery pollinose. Hairs dispersed, pale and at least as long as width of t3 at base. Laterally 3 brown setae on first tergite. Female ovipositor as in Figs 39B, 40K.
Distribution— Malawi, Tanzania, Zimbabwe.
