Eudorylas hirsutus sp. nov.

( Figs 23G–L )

Diagnosis: Gonopods equally long, OG with short hairs; hypandrium with circular lobes deflected by 45 degrees in ventral view; phallic guide with long lateral hairs (6–7) in ventral view, PG curved towards SS in lateral view; ejaculatory apodeme mushroom shaped.

Type material: Kenya: 1♂, HT, “ Nyong Forest , 6500’ ” [hand-written], Nairobi, x.1934., F.W. Edwards, B.M. 1935-203. ( BMNH).

Male

Head. Third antennal segment acuminate; brown. Face silvery pollinose. Frons, upper part subshining black, lower part greasy on HT (probably silvery pollinose); eyes touching for distance equal to 3.5 times ocellar triangle. Occiput, lower half silvery pollinose, upper half brownish pollinose.

Thorax. Humeri brown. Mesonotum (viewed obliquely from front) and scutellum brownish pollinose; also brown from the side. Scutellum with very few, short hairs. Dorsocentral hairs weakly developed. Halter brown, stem darker.

Legs. Trochanters, femora, knees and tibiae entirely pale brown (f3 shining ventrally and posteriorly). Tarsal segments brown, last segment dark brown. Ventroapical row of 6–7 short dark spines on first four femora; 4–5 spines on 3rd femur. Subapical (distal) spines on first four tibiae missing. No anteromedial hairs on 3rd tibia. Hind trochanter shining brown ventrally, with 1–2 dark hairs on ventral side. Pulvilli shorter than last tarsal segment.

Wing. Fourth costal section 0.5 times as long as third costal section. Cross-vein R-M at 2/5 of discal cell. Pterostigma fully coloured. Hairs on tegula missing.

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

Genitalia. Surstyli subsymmetrical, OS broader in dorsal view, both wide distally in lateral view; epandrium narrow; ST8 deformed ( Fig. 23G ). SES uncertain; gonopods equally long, OG with short hairs; hypandrium with circular lobes deflected by 45 degrees in ventral view ( Fig. 23L ); phallic guide with long lateral hairs (6–7) in ventral view, PG curved towards SS in lateral view ( Fig. 23I ); phallus trifid, branches with minute hairs; ejaculatory apodeme broad at tip (mushroom shaped); sperm pump round ( Fig. 23J ).

Female—Unknown.

Distribution— Kenya.

Etymology —Named after the distal part of the phallic guide being hairy (from Latin).
