Podophthalma bayaoniana  Karsch 1878: 326, plate 2, fig. 8 (female, misidentified).

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).
