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), 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 and 121–125 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, 82, 129, 44 and 180 correspondingly).
