description: Eudorylas porrectus (Hardy, 1949)
(Figs 29H–M)
Dorilas (Eudorylas) porrectus Hardy 1949 a: 51.
Diagnosis: Fourth costal section 0.6 times as long as third costal section. Cross-vein R-M between 1/3 and 1/2 of discal cell. Hairs on tegula: 6–7 stronger brown setae. T5 3.5–4 times as long as ST8. SES clear, with hairs on border with SS; gonopods symmetrical; hypandrium with broadened lobes; phallic guide narrowing at tip, but rounded, with hairs at base; phallus with very short branches distally and with membranous lobes along the whole PH.
Type material: Ghana: 1♂, HT, Obuasi, Ashanti, W.Africa, 27.IX, 1907 [as “ 29.IX.1907 ” in Hardy 1949 a], Dr. W.M. Graham, 1908-245; [hand-written:] “Caught on leaf in dense bush” (BMNH).
Male
Head. [no 3rd antennal segment on HT] Face silvery pollinose, except shining black median line on lower half. Frons, upper part subshining black, lower part silvery pollinose with shining black spot in the middle (as large as 2nd segment); eyes touching for distance equal to 3–3.5 times ocellar triangle. Occiput, upper half black, lower half silvery pollinose.
Thorax. Humeri pale brown. Mesonotum (viewed obliquely from front) brownish pollinose, along anterior margin more silvery; brownish from the side. Scutellum brownish pollinose, 6–7 pairs of pale, short hairs. Dorsocentral hairs weakly developed. Halter black, stem yellowish.
Legs. Trochanters and base of femora brown, femora black, knees yellow-brown, tibiae black. Tarsal segments dark brown, last segment black. Ventroapical row of 4 short, black spines on first four femora; 4–5 short, whitish hairs on 3rd femur. Subapical (distal) spines on first four tibiae absent. No anteromedial hairs on 3rd tibia. Hind trochanter covered by short white pubescence on ventral side. Pulvilli as long as last tarsal segment.
Wing. Fourth costal section 0.6 times as long as third costal section. Cross-vein R-M between 1/3 and 1/2 of discal cell. Pterostigma fully coloured. Hairs on tegula: 6–7 stronger brown setae.
Abdomen. Viewed obliquely from front tergites black with brownish pollinosity, hind margins: distal half of T1,5 and distal 1/5 of T2–4 silvery pollinose, sides posteriorly with grey patches. Hairs dispersed, dark, as long as width of t3 at base. 8–10 dark lateral spines in a patch on first tergite and also longer hairs laterally on T2. Postabdomen in dorsal view: T5 3.5–4 times as long as ST8. Genitalia without dissection: ST8 short, black, m.a. posteroventrally directed, rounded triangle, SS yellow-brown.
Genitalia. Surstyli subsymmetrical; ST8 large with distinct m.a. (Fig. 29I). SES clear, with hairs on border with SS; gonopods symmetrical; hypandrium with broadened lobes; phallic guide narrowing at tip, but rounded, with hairs at base; phallus with very short branches distally and with membranous lobes along the whole PH (Fig. 29M); ejaculatory apodeme linear; sperm pump small, roundish (Fig. 29L).
Female—Unknown.
