Diagnosis

The males of Afroneutria immortalis comb. nov. differ from those of the other species of the genus by the elongated tip and short additional laminar projection of the embolus on the male palp ( Figs 5 View Fig. 5 A, 14 View Fig. 14 A; Polotow & Brescovit 2014: fig. 8f, indicated by an arrow) and the shape of the RTA ( Fig. 5 View Fig. 5 C; Polotow & Brescovit 2014: fig. 8d). The females can be distinguished by the acute lateral spurs ( Figs 5 View Fig. 5 D, 12 A) and straight dorsal and ventral spermathecae with a swollen apical area ( Fig. 5 View Fig. 5 E).
