Diagnosis

The male of this species is recognized by the shape of the RTA, which is about as long as the length of the tibia, slightly curved down and dorsoventrally Fattened; it has a typical large ventral bulge; extremity of the MA is slightly indented ( Fig. 8 View Fig. 8 A). Females are characterized by the epigyne ( Figs 5 View Fig. 5 G – H, 6 C) in which the three sections of the frontal margin are strongly curved.

Etymology

The name refers to the wide area of distribution in the Sahel zone of western Africa.
