Euprosthenops pulchellus Pocock  1902: 18, plate 3, fig. 6, female holotype from South Africa, Eastern Cape Province, Grahamstown ( BMNH 01.3.13.194) (examined); Blandin 1977: 143, figs 9, 15, 19, 20b (transferred from Euprosthenops  )  .

Note. Males and females were found together in several lots from South Africa ( NCA collection).

Diagnosis. The males of Euprosthenopsis pulchella  resemble those of E. armata  by the short distal tegular projection ( DTP, Figs 27, 29), by the short and membranous median apophysis ( MA, Figs 27, 29), by the large and translucent conductor ( C, Figs 27, 29) and by the concave retrolateral tibial apophysis ( RTA, Figs 28, 30). Males of E. pulchella  can be distinguished by the large and wide conductor ( C, Figs 27, 31, 32), the long and thin embolus ( E, Figs 27, 32), the elongated and slender distal tegular apophysis ( DTA, Figs 27, 32) and the tooth-like projection at the base of the retrolateral tibial apophysis ( RTA, Figs 28, 33, 34).

Chelicerae dark brown, with scattered white bristles anteriorly (Fig. 25). Retromargin of left cheliceral fang furrow with three teeth, equidistant and equal in size; promargin with three teeth, median tooth largest. Sternum dark brown with a median irregular light brown band, bristly; 2.07 long, 1.91 wide (Fig. 26). Labium light brown, dark brown laterally, 0.35 long, 0.70 wide (Fig. 26).

Ventral pairs of macrosetae on tibiae: I-4; II-4; III-4; IV-4. Abdomen 6.64 long, dark brown with a lateral patch of white bristles forming two paramedian white bands (Fig. 23). Venter brown with a thin light brown band. Palpus with a short and rounded distal tegular apophysis ( DTA) (Figs 27, 31, 32). Cymbium 2.34 long. Median apophysis ( MA) short, slender and membranous (Figs 27, 31, 32). Conductor large, wide and translucent (Figs 27, 31, 32).
