Eudorylas angolae sp. nov.

( Figs 14G–K )

Diagnosis: The thorax and the abdomen of this species are covered with exceptionally dense, pale hairs. The fifth tergite and the last tarsi are dark, but the body is generally yellow (abdomen shining). Surstyli are slightly asymmetrical, bent ventrally; ST8 with large m.a, occupying 2/3 of width of ST8. SES with hairs at base of SS; gonopods symmetrical, shorter than PG; phallic guide straight and blunt in ventral view, bent towards SS and pointed at tip in lateral view; phallus trifid, long and coiled, distal part membranous.

Type material: Angola: 1♂, HT, Salazar , I.I.A.A., 9–15.iii.1972, (A26), Southern African Exp., B.M. 1972-I. ( BMNH); 1♂, PT, same data as HT ( HNHM) .

Male

Head. Third antennal segment long acuminate; yellow. Face silvery pollinose. Frons, upper part shining black, lower part silver-grey pollinose; eyes touching for distance equal to 4 times ocellar triangle. Occiput, lower half silvery pollinose, upper half less so.

Thorax. Humeri yellow. Mesonotum (viewed obliquely from front) brownish yellow, along anterior margin somewhat silvery; slightly greyish from the side. Scutellum yellow, with numerous longer pale hairs. Dorsocentral hairs very well developed with several hairs also in the notopleural depression. Halter yellow, knob dark brown.

Legs. Femora, knees and tibiae yellow (t3 brownish). Tarsal segments brownish yellow, last segment dark brown. Ventroapical row of 8–9 short dark spines on mid femora (no spines on f1); No spines on 3rd femur. Subapical (distal) spines on first four tibiae present. No anteromedial hairs on 3rd tibia. Hind trochanter with 4–5 pale hairs on ventral side. Pulvilli as long as last tarsal segment.

Wing. Fourth costal section 1.2 times as long as third costal section. Cross-vein R-M at 1/3 of discal cell. Pterostigma fully coloured. Hairs on tegula missing.

Abdomen. Viewed obliquely from front tergites completely shining yellow-brown, only T5 shining black. Hairs dispersed, long, pale and well developed. Laterally 5–6 long yellow spines on first tergite. Postabdomen in dorsal view: T5 2.5 times as long as T8. Genitalia undissected: completely yellow, m.a. large, occupying 3/4 of width of ST8.

Genitalia. Surstyli slightly asymmetrical, (OS broader in dorsal view), both bent ventrally; ST8 with large m.a, occupying 2/3 of width of ST8 ( Fig. 14G ). Borders of SES uncertain, with hairs at base of SS; gonopods symmetrical, shorter than PG; phallic guide straight and blunt in ventral view ( Fig. 14K ), bent towards SS and pointed at tip in lateral view ( Fig. 14H ); phallus trifid, long and coiled, distal part membranous.

Female—Unknown.
