Figs 1C, 2A, 3 A–F, 4A–F, 5A–F, 6A–F, 8A–F

Prodidomus scaber Purcell, 1904: 172, pl. 11, figs 41, 42 (Female holotype from Prince Albert, Western Cape [33°13’36.57”S, 22°2’8.57”E], South Africa, deposited in SAMC 3016, examined).

Austrodomus scaber Cooke, 1964: 264, figs 32, 37, 60 (only female; male = Purcelliana problematica Cooke, 1964).

Diagnosis. Males of Austrodomus scaber differ from those of A. gamsberg sp. nov. by the palp with the distal half of the embolus slender and tapering (distal half of the embolus robust and ventrally bent in the middle in A. gamsberg sp. nov.) (Figs 6A, C, 8A, B). Females resemble those of A. zuluensis in having the posterior margin of the epigynal plate sinuous and without posterior projections (Figs 7A, 8D), but differ by the vulva with the laterally convoluted part of the copulatory ducts almost the same width as the proximal part (1/3 of the width in A. zuluensis), and by the inconspicuous spermathecae (well-defined in A. zuluensis) (Fig. 8E).
