Remarks. Afroestricus vittatusis distinguished from most congeners by the characters in the key and terminalia ( Figs. 177–186). It is similar to A. sankofaand A. voraxin an unusually narrow base of cell m 1, the strongly arched base of vein M 1, strong black posteroventral bristle on the apical 1/3 of the middle femur of both sexes, and a prominent apical spur on the hind tibia of the male, but is distinguished from them by the presence of a deep dorsoapical notch on the epandrium ( Fig. 177).
