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 View Figs 168–181 , 186–187 View Figs 182–187 ), 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 View Figs 37–45 , 48 View Figs 46–51. 46–48 ). The cheeks in M. petroae   gen. et sp. nov. are covered with yellowish white hairs ( Figs 170–171, 176–177 View Figs 168–181 ) 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 View Figs 37–45 ). The apical projection (ApP) in M. petroae   gen. et sp. nov. is small, rounded in outline and slightly bent dorsally ( Fig. 158 View Figs 154–160 ), while in M. botswana   gen. et sp. nov. the ApP is large and robust ( Fig. 31 View Figs ). 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 View Figs 168–181 ) and short wide stripe just behinf AMEs of live specimens ( Figs 49– 51 View Figs 46–51. 46–48 ), while in M. botswana   gen. et sp. nov. the eye field has a short narrow white stripe just behind AMEs ( Figs 42, 44 View Figs 37–45 ).
