Diagnosis

Manzuma petroae gen. et sp. nov. is most similar to M. botswana gen. et sp. nov. in body coloration. The males of M. petroae gen. et sp. nov. differ in having the clypeus covered with long white hairs with a diamond-shaped patch of brown hairs between the AME and on the upper half of the clypeus in the center (Figs 170–171, 176–177, 186–187), while in M. botswana gen. et sp. nov. the clypeus is covered with short brown scales, medially with a thin vertical stripe of white hairs (Figs 39, 48). The cheeks in M. petroae gen. et sp. nov. are covered with yellowish white hairs (Figs 170–171, 176–177) while in M. botswana gen. et sp. nov. the cheeks have a thin white line running from the ALEs to sides of carapace (Fig. 38). The apical projection (ApP) in M. petroae gen. et sp. nov. is small, rounded in outline and slightly bent dorsally (Fig. 158), while in M. botswana gen. et sp. nov. the ApP is large and robust (Fig. 31). The females of M. petroae gen. et sp. nov. differ in the uniform colour of the eye of specimens preserved in alcohol (Figs 178, 180) and short wide stripe just behinf AMEs of live specimens (Figs 49– 51), while in M. botswana gen. et sp. nov. the eye field has a short narrow white stripe just behind AMEs (Figs 42, 44).
