Note Blackwall (1865)indicated one female as the typematerial used in the description of Ctenus velox, but two adult females were found in the OUMNH collection and, according to the label, both were designated as types. Based on the original description we here designate the smaller specimen as the lectotypeand the other female as the paralectotype.
Diagnosis The males of Afroneutria velox comb. nov.differ from males of the other species of the genus by the laminar and truncated tip and the additional subdistal projection of the embolus ( Fig. 1B) and the shape of the RTA ( Fig. 3A–C). The females can be distinguished from the remaining species of the genus by the acuminated and short lateral projections of the epigynum and rounded dorsal spermathecae in the vulva ( Fig. 3D–E).
