Diagnosis

Manzuma botswana gen. et sp. nov. is most similar to M. petroae gen. et sp. nov. in body coloration. The males of M. botswana gen. et sp. nov. differ in having the clypeus covered with short brown scales, medially with a thin vertical stripe of white hairs ( Figs 39 , 48 ), while in M. petroae gen. et sp. nov. the clypeus is covered with long white hairs with a diamond-shaped patch of brown hairs between AME and on upper half of clypeus in the center ( Figs 170–173, 176–177 , 186–187 ). The cheeks in M. botswana gen. et sp. nov. have a thin white line running from ALEs to the sides of the carapace ( Fig. 38 ), while in M. petroae gen. et sp. nov. the cheeks are covered with yellowish-white hairs ( Figs 171, 177 ). Apical projection (ApP) in M. botswana gen. et sp. nov. is large and robust ( Fig. 31 ), while ApP in M. petroae gen. et sp. nov. is smaller in size, rounded in lines and slightly bent dorsally ( Fig. 158 ). The females of M. botswana gen. et sp. nov. differ in having a short narrow white stripe on the eye field just behind the AMEs ( Figs 42, 44 ), while females of M. petroae gen. et sp. nov. have short wide stripe ( Figs 49–51 ), almost invisible in specimens preserved in alcohol ( Figs 178, 180 ).

Etymology
