( Figs 39T–U )

Dorilas (Eudorylas) angustus Hardy 1952: 8 .

Diagnosis: Third antennal segment acute, two times longer than wide; piercer bent at the point where narrowing.

Type material: Burundi: 1♀, HT, Urundi. Terr. Bururi riv. , Sikuvayaye alt. 1800 m., 20-xii-1948, F. François, R.I.Sc.N.B. I.G. 19.700 ( ISNB) .

Female

Head. Third antennal segment acute, two times longer than wide; yellow. Face silvery pollinose, two times broader than frons. Frons, upper part silvery shining, less so in front of ocellar triangle, lower part completely silvery. Occiput silvery pollinose.

Thorax. Humeri yellow. Mesonotum (viewed obliquely from front) black with brownish pollinosity; brown with silver pollinosity from the side. Scutellum yellow-brown, paler towards tip; inconspicuous, pale hairs on margin. Dorsocentral hairs very weakly developed. Halter yellow-brown, stem long.

Legs. Completely yellow, last tarsal segment somewhat darker. Ventroapical row of 8–12 black spines on first four femora; no 3rd leg on HT. Subapical (distal) spines on first four tibiae distinct, long. Anteromedial hairs on 3rd tibia: 1 strong bristle on outside, based on Hardy's description. Pulvilli two times longer than last tarsal segment, claws 1.3 times longer than pulvilli (on 1st leg).

Wing. Fourth costal section 1.1 times as long as third costal section. Cross-vein R-M beyond 2/5 of discal cell. Pterostigma fully coloured. 2 hairs on tegula.

Abdomen. Viewed obliquely from front tergites silvery pollinose, brownish in the middle on T3–6; sides silvery pollinose. Hairs dispersed, distinct and pale. Two black lateral spines on first tergite. Ovipositor ( Figs 39T–U ): base visible, piercer bent at the point where narrowing.

Remarks —This is a doubtful species, since its identity is based on a single female specimen, and the characters of the body and terminalia are not sufficient to separate it from other species.

Distribution— Burundi.
