Diagnosis: Large species. Surstyli bent ventrally and towards each other; epandrium asymmetrical, left side longer, cerci shifted to the right; SES appears to be divided, 20–22 hairs on each side; phallic guide sharply pointed, broadens before end. In lateral view ( Fig. 26A ) OS with a large process at the base above PG; phallus with supporting structure and a distinct, long process between PG and PH ; the trifid part of PH seems to be separated from the rest. Type material: Kenya : 1♂ , HT, Van Someren , Meru , 7/43 [ July 1943 ]; Pres. by Com. Inst. Ent. B. M. 1952-299; “ Dorilas meruensis Det. 1947 D.E. Hardy ” ( BMNH ); 1♂ , PT, same collecting data as HT ( USNM ) . Male Head . Third antennal segment acute; yellow (arista brown). Face silvery shining. Frons, upper part very narrow, black, lower part silvery shining; eyes touching for distance equal to 2 times ocellar triangle. Occiput greyish pollinose. Thorax . Humeri yellow-brown. Mesonotum (viewed obliquely from front) black with brownish pollinosity, somewhat greyish along anterior margin; greyish pollinose from the side. Scutellum black with brownish pollinosity, hairs missing. Dorsocentral hairs very weakly developed. Halter yellow, base somewhat brown. Legs. Trochanters and base of femora dark brown, femora black, except yellowish distal end (first four femora silvery, f3 shining black on posteroventral side), knees yellow, tibiae pale brown, hind tibia slightly thickened in the middle. Tarsal segments yellowish brown, last segment dark brown. Ventroapical row of 10–12 short black spines on first four femora; 8–10 somewhat longer spines on 3rd femur. Subapical (distal) spines on first four tibiae missing. No anteromedial hairs on 3rd tibia. No hairs on hind trochanter on ventral side. Pulvilli somewhat smaller than last tarsal segment. Wing. Fourth costal section 1.4–1.5 times as long as third costal section. Cross-vein R-M before 1/3 of discal cell. Pterostigma fully coloured (at least distal 3/4). Hairs on tegula uncertain (probably missing). Abdomen . Viewed obliquely from front T1 and anterior margin of T2 silver pollinose, other tergites faintly so; hind margins shining black with engraved stripes; sides greyish pollinose, particularly T5. Hairs very short and weakly developed. No lateral spines on first tergite, but 2 dark “lobes” at base (seems to protect the base of the halter). Postabdomen in dorsal view: S7 visible; T5 1.5 times as long as ST8. Genitalia without dissection: enlarged, EP brown, SS yellowish; large oval membranous area, as long as 2/3 of height of ST 8 in caudal view. Genitalia. Surstyli bent ventrally and towards each other; the whole epandrium is turned, not symmetrical, left side longer, cerci shifted to the right; ST8 wide ( Fig. 26B ). SES appears to be divided, 20–22 hairs on each side; gonopods symmetrical, rounded; hypandrium connected to EP ( Fig. 26F ); phallic guide sharply pointed, broadens before end; phallus trifid, not long, curved; ejaculatory apodeme fan shaped; sperm pump with 2 projections ( Fig. 26D ). In lateral view ( Fig. 26A ) OS with a large process at the base above PG; phallus with supporting structure and a distinct, long process between PG and PH ; the trifid part of PH seems to be separated from the rest. Female—Unknown. Distribution— Kenya .
