Euprosthenopspulchellus Pocock1902: 18, plate 3, fig. 6, female holotypefrom South Africa, Eastern Cape Province, Grahamstown( BMNH 01.3.13.194) (examined); Blandin 1977: 143, figs 9, 15, 19, 20b (transferred from Euprosthenops). Euprosthenopsis pulchella(Pocock, 1902). Platnick 2014.
Note. Males and females were found together in several lots from South Africa ( NCAcollection).
Diagnosis. The males of Euprosthenopsis pulchellaresemble those of E. armataby 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. pulchellacan 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).
