Eudorylas inornatus (Hardy, 1949)

( Figs 24A–F )

Dorilas (Eudorylas) inornatus Hardy 1949 a: 37 .

Diagnosis: Two longer anteromedial hairs on 3rd tibia, as long as width of tibia. Surstyli symmetrical, pointing towards each other, and with a row of hairs at base; epandrium wider than long; m.a. as long as half width of ST8; SES with a group of hairs behind PH in ventral view; gonopods subsymmetrical, with hairs on inner edge; phallic guide widening apically, with 3 additional branches laterally; phallus trifid (little teeth visible in lateral view) with membranous supporting structure (gonostylus?); ejaculatory apodeme short, “hat”-like; sperm pump little, rounded.

Type material: Kenya: 1♂, HT [no head], H.J.A. Turner, Naivasha, 7. [July] 37., BM 1953-357. ( BMNH); 1♂, PT, same data as HT ( USNM) .

Male

Head. (no head on HT and PT)

Thorax. Humeri pale brown. Mesonotum (viewed obliquely from front) brownish pollinose, along anterior margin less so; black from the side with faint greyish pollinosity. Scutellum brownish pollinose, with 4–5 pairs of distinct but pale hairs. Dorsocentral hairs very weakly developed. Halter brown.

Legs. Trochanters brown, base of femora yellow-brown, femora black, shining ventrally (on all legs), knees yellow, tibiae yellow-brown with dark rings in the middle, t3 slightly curved, faint thickening in the middle. Tarsal segments yellow-brown, last segment black. Ventroapical row of 10–12 short, stout, black spines on first four femora; 6–8 longer spines on 3rd femur. Subapical (distal) spines on first four tibiae present, but weakly developed. Two longer anteromedial hairs on 3rd tibia, as long as width of tibia. Hind trochanter with white hair on ventral side, and black hair on outer surface as long as width of femur at base. Pulvilli shorter than last tarsal segment on hind leg.

Wing. Fourth costal section 0.9 times as long as third costal section. Cross-vein R-M at 1/3 of discal cell. Pterostigma fully coloured, proximal border as a line. Hairs on tegula absent.

Abdomen. Viewed obliquely from front tergites brownish pollinose, hind margins somewhat greyish laterally. Hairs dispersed, short and weakly developed, longest on ST8. Lateral spines on first tergite: 3–6 in a row. Postabdomen in dorsal view: T5 1.2 times as long as ST8. Genitalia without dissection: round m.a., SS visible in lateral view, yellowish cerci and SS.

Genitalia. Surstyli symmetrical, pointing towards each other, and with a row of hairs at base; epandrium wider than long; ST8 very wide, m.a. as long as half width of ST8 ( Fig. 24B ). SES borders unclear, with a group of hairs behind PH in ventral view; gonopods subsymmetrical, with hairs on inner edge; phallic guide widening apically, with 3 additional branches laterally ( Fig. 24F ); phallus trifid (little teeth visible in lateral view) with membranous supporting structure (gonostylus?) ( Fig. 24A ); ejaculatory apodeme short, “hat”-like; sperm pump little, rounded ( Fig. 24D ).

Female—Unknown.

Distribution— Burundi, Democratic Republic of Congo, Kenya, Madagascar, Mozambique.
