Eudorylas protumidus sp. nov.

( Figs 30A–E )

Diagnosis: Surstyli asymmetrical, strongly bent ventrally, both with broad distal parts in lateral view; no m.a. on ST8. Gonopods equal in length, OG with a distinct process, directed medially; phallic guide broad, tip pointed and with a sickle shaped apical appendix on the left in ventral view; phallus trifid, branches short.

Type material: South Africa: 1♂, HT, Cape Prov., Pakhuis Pass, east side, 17-VIII-1973, ME Irwin, 600 m, meadow with flowers, 3219Aa ( NMSA) .

Male

Head. Third antennal segment long 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 2.5 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 more greyish; also greyish from the side. Scutellum brown, with 6–7 pairs of short, pale hairs. Dorsocentral hairs weakly developed. Halter yellow-brown, knob dark brown.

Ventroapical row of 5–6 short dark spines on mid femora; 3–4 pale hairs on 3rd femur (no spines on f1). Subapical (distal) spines on first four tibiae present. One short dark anteromedial hair on 3rd tibia. Hind trochanter with 1–2 short, pale hairs on ventral side. Pulvilli distinctly shorter than last tarsal segment.

Wing. Fourth costal section as long as third costal section. Cross-vein R-M beyond 1/3 of discal cell. Pterostigma fully coloured. Two pale hairs on tegula.

Abdomen (already dissected). Viewed obliquely from front tergites (T1,2) brownish pollinose. Hairs dispersed, short and weakly developed. Laterally spines on first tergite.

Genitalia. Surstyli asymmetrical, strongly bent ventrally, both with broad distal parts in lateral view; epandrium elongated, almost as long as ST8; no m.a. on ST8 ( Fig. 30B ). SES missing; gonopods equal in length, OG with a distinct process, directed medially; phallic guide broad, tip pointed and with a sickle shaped apical appendix on the left in ventral view ( Fig. 30E ); phallus trifid, branches short.
