Figs 83–106 , 200

Langelurillus kenyaensis Dawidowicz & Wesołowska, 2016: 448 , figs 43–44; ♀ holotype from MEUU, not examined.

Diagnosis

The males of M. kenyaensis gen. et comb. nov. can easily be distinguished from those of all other species of Manzuma gen. nov. by dorsal bulge on palpal tibia ( Fig. 84 ) and palpal patella brown or brownish yellow dorsally, flattened, almost without hairs, iridescent ( Fig. 102 ). The females of M. kenyaensis gen. et comb. nov. can easily be distinguished from other Manzuma gen. nov. species by long introductory parts of the insemination ducts ( Figs 90–91, 93 ).
