Male genitalia: harpe broad and round in lateral view; harpe/gvc index 0.50; ventromedial margins of harpes not touching at distoventral margin of gvc, ventromedial margin of harpe convex and touching in basal third, concave in middle third, straight and diverging distolaterally in apical third; harpe with at least one ventral seta restricted to apical two thirds. Etymology The species is named after the Swahili word ‘ njia ’ which means ‘path’ or ‘aisle’, with reference to the large forest aisle of the Kakamega Forest which is the type locality.

Male genitalia in ventral (A), lateral (B) and dorsal (C) views. D . Habitus in lateral view. Female Unknown. Variation Unknown. Biology Host unknown, specimen collected from leaf litter. Distribution Afrotropical: Kenya . Remarks Comparison with similar species See remarks under A. kakamegaensis sp. nov. Condition of type material The male genitalia were lost during processing of the species. Yet, with the specimen still present and the detailed images and description of the male genitalia at hand, allowing a very robust diagnosis, we decided to describe this species as new.
