Euprosthenops australis Simon 1898: 12, female from South Africa, Hebron (MNHN 17418) (not examined); Lawrence 1947: 33, fig. 18; Roewer 1955b: 144, fig. 62; Blandin 1976: 70, figs 6-7, 14, 19, 22; Blandin 1978: 26, fig. 6c.
Note. Males and females were found together in several sites from South Africa (NCA collection) - see Material Examined.
Diagnosis. The males of Euprosthenops australis resemble those of E. bayaonianus and E. proximus by the presence of a large, flattened distal tegular apophysis (DTA), and its hook-like, curved tip (Figs 9, 14, 18, 20), by the membranous median apophysis (MA, Figs 9, 14, 18, 20) and by the finger-like retrolateral tibial apophysis (RTA, Figs 10, 17, 19, 21). Euprosthenops australis males can be distinguished from all other members of the genus by the slender and elongated distal tegular projection (DTP, Figs 9, 15) and by the rounded prolateral projection (arrow) on the distal tegular apophysis (DTA, Figs 9, 15).
