Diagnosis

Manzuma nigritibia   is most similar to M. jocquei   and M. lympha   in body coloration. The males can be distinguished by the coloration of the clypeus and cheeks. The clypeus has a diamond-shaped patch of brown hairs between AME and on the upper half of the clypeus. The cheeks are covered with a long white hairs from the ALEs to the margin of carapace ( Figs 145, 147 View Figs 143–153 ), while in M. jocquei   and M. lympha   the upper half of the cheeks under ALEs are covered with a short brown scales and the basal half covered with a long white hairs ( Figs 75–77 View Figs 72–82 and 121–125 View Figs 117–130 correspondingly). The females cannot be distinguished from M. jocquei   and M. lympha   but can be distinguished from M. botswana   gen. et sp. nov. and M. petroae   gen. et sp. nov. by the absence of white stripes of scales running from the outer rim of the AME’s to the lateral sides of carapace (cf. Figs 152 View Figs 143–153 , 82 View Figs 72–82 , 129 View Figs 117–130 , 44 View Figs 37–45 and 180 View Figs 168–181 correspondingly).
