Eudorylas gabela sp. nov.

( Figs 21H–L )

Diagnosis: Wing with an extra spurious cross-vein closing the pterostigma at the end of the subcostal vein. Fourth costal section very short compared to the third. Surstyli subsymmetrical, bent ventrally; epandrium larger than ST8, broadest in the middle; ST8 small, without m.a. Gonopods short, rounded; hypandrium broad, lobes rectangular, hypandrial apodeme distinct; phallic guide broad at base and with two lobes surrounding PH.

Type material: Angola: 1♂, HT, Cachoeiras , 20 mls., SW. Gabela, 18–19.iii.1972. (A32), Southern African Exp. 1972–I ( BMNH) .

Other material examined: South Africa: 1♂, 1♀ [same pin], Gillits, Pinetown district , Natal, S.A. Africa, B. & P. Stuckenberg, 26. 11. 1970. (both NMSA) [these specimens were examined after the type has been selected, and sent back, therefore they are not part of the type series]
