Remarks. The species was described by Serrano (2000) based on two specimens from Angola. The material now examined allows extending its distribution to central and eastern Africa, being first reported for the Republic of South Africa, Tanzania and Zimbabwe.

Male genitalia. Description and drawings of median lobe in lateral and dorsal views and left paramere shape were provided by Serrano (2000, Figs. 13 , 14 ).

Female genitalia ( Fig. 4d ). Gonocoxite 1 subtriangular; gonocoxite 2 largely sickle shaped, apex hardly pointed; dorsal surface concave, proximal half covered with numerous setae, subapical inner margin with four setae; ventral surface slightly convex, some long and minor setae near outer margin in apical half.

Distribution: Angola, Namibia, Republic of South Africa, Tanzania, Zimbabwe.
