Diagnosis

Manzuma tanzanica is most similar to M. jocquei , M. lympha and M. nigritibia in body coloration. The males can be distinguished from M. jocquei and M. lympha by the poorly developed apical projection (well developed in M. jocquei ) (cf. Figs 190, 192 , 57–58 , 64 and 109, 111 correspondingly); from M. nigritibia it can be distinguished by the coloration of the clypeus and cheeks. The upper half of cheeks under ALEs are covered with short brown scales and the basal half of cheeks covered with long white hairs ( Figs 196–197 ) while in M. nigritibia the clypeus has a diamond-shaped patch of brown hairs between AME and on upper half of clypeus and the cheeks covered with long white hairs from ALEs to margin of carapace ( Figs 145, 147 ).

Etymology

The specific epithet is named after the country of origin, Tanzania.
