Distribution ( Tables 1, 2; Fig. 196 View FIGURE 196 ). Niger and Uganda; collected in August and September ( Tables 1, 2).

Etymology. Latin vorax for vicious, referring to the predaceous habits of asilids.

Remarks. Afroestricus vorax is similar to A. sankofa and A. vittatus in the unusually thick femora of the male, the stout posteroventral bristle on the middle femora of both sexes but is distinguished from them by the characters of the terminalia ( Figs. 187–192 View FIGURES 187–192 ).
