Diagnosis

The males of Afroneutria erythrochelis comb. nov. differ from those of the other species of the genus by the swollen retrolateral area of the cymbium, the curved median apophysis, the retrolateral base of the embolus and by the laminar projection of the embolus extending beyond its tip (Figs 7 A–B, 15 C– D). The females can be distinguished by the short lateral projections of the epigynum and the dorsal spermathecae curved ventrally, forming a spiral in the vulva (Figs 7 C–D, 12 C).
