Dasydorylas bodocsi sp. nov.

( Figs 7G–K )

Diagnosis : Surstyli slightly asymmetrical, strongly bent ventrally, OS with a basal process. SES with numerous thick hairs; gonopods pointed, OG with a lobe medially; hypandrium short, rounded; phallic guide in ventral view: broad, sides parallel, narrowing towards tip, with a pointed projection on the left side; phallus trifid, branches short. Type material: Zimbabwe: 1♂, HT, N. Vumba , S. Rhodesia , 22.7.1964, D. Cookson [hand-written] ( NMSA) ; 2♂, PTs, same data as HT except 16.5.1964 ( HNHM) and 9.7.1964 ( NMSA) .

Other material examined: Kenya: 1♂, Ngong Forestry Station , 13–18 Jan. 1968, Malaise trap, Krombein & Spangler ( USNM) [specimen not included in type series due to the fact that Kenya is further away from the locus tipicus].
