Wide spread; captured from November through August. 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). 1915-06-30 AMNH Democratic Republic of the Congo 0.5 Types 1308 25.166666 Stanleyville 66 67 1 holotype 1915-06-16 AMNH Democratic Republic of the Congo 0.5 Stanleyville 1308 25.166666 66 67 1 allotype 1915-03 1915-04-31 1915-03 AMNH Democratic Republic of the Congo 0.5 Stanleyville 1308 25.166666 66 67 1 paratype 1915-06-22 USNM Bromley Democratic Republic of the Congo -6.0 Zambi Congo 0 12.833333 66 67 1 paratype 1972-03-07 1972-03-08 1972-03-07 BMNH N.
