Prodidomus scaber Purcell, 1904: 172   , pl. 11, figs 41, 42 (Female holotype from Prince Albert   GoogleMaps , Western Cape [33°13’36.57”S, 22°2’8.57”E], South Africa, deposited in SAMC 3016 View Materials , 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 View FIGURE 6 , 8A, B View FIGURE 8 ). Females resemble those of A. zuluensis   in having the posterior margin of the epigynal plate sinuous and without posterior projections ( Figs 7A View FIGURE 7 , 8D View FIGURE 8 ), 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 View FIGURE 8 ).

Description. Male (NCA 2013/5520). Total length: 2.30. Carapace 1.07 long, 0.77 wide; Abdomen 1.22 long, 0.75 wide; Sternum 0.77 long, 0.53 wide; Spinnerets ALS 0.11 long, 0.13 wide. Eye diameters: AME 0.08, ALE 0.09, PME 0.08, PLE 0.09; interdistances: AME–AME 0.05, PME–PME 0.05. Chelicerae 0.43 long. Leg formula 4123; measurements: I: 3.83 (1.06, 0.70, 0.75, 0.78, 0.54); II: 3.04 (0.80, 0.58, 0.58, 0.61, 0.48); III: 2.54 (0.69, 0.34, 0.56, 0.51, 0.44); IV: 4.30 (1.18, 0.61, 1.03, 0.85, 0.64). Leg spination: III—femur d1-1-0; tibia v0-1r-1r, r0-1-0; metatarsus v0-0-1, r1-1-1. IV—femur d1-1-0; tibia v2-2-2; metatarsus v2-2-1. Palp: femur with one dorsal spine; vRTA subrectangular in ventral view ( Fig. 8B View FIGURE 8 ); dRTA truncated in retrolateral view ( Fig. 8C View FIGURE 8 ); conductor triangular ( Fig. 8B View FIGURE 8 ).

Female. (NCA 2013/5520). Total length: 2.81. Carapace 1.25 long, 0.82 wide; Abdomen 1.45 long, 1.15 wide; Sternum 0.86 long, 0.62 wide; Spinnerets ALS 0.25 long, 0.22 wide. Eye diameters: AME 0.09, ALE 0.08, PME 0.09, PLE 0.09; interdistances: AME–AME 0.04, PME–PME 0.07. Chelicerae 0.52 long. Leg measurements: I: 3.60 (1.0, 0.69, 0.73, 0.64, 0.55); II: 3.0 (0.88, 0.54, 0.60, 0.55, 0.44); III: 2.66 (0.73, 0.44, 0.56, 0.49, 0.45); IV: 4.16 (1.08, 0.58, 1.06, 0.83, 0.63). Leg formula 4123. Leg spination: III—femur d0-1-0; tibia v2-1r-1r, r0-1-0; metatarsus v0-0-2, r0-1-1. IV—femur d1-1-0; tibia v1r-2-2, r0-1-0; metatarsus v1r-1r-2. Epigyne: copulatory openings small, slightly larger than posterior pouch-like structures, separated from each other by half their width ( Fig. 8D View FIGURE 8 ).

Variation. Total length (5 males): 1.66–2.50; (5 females): 2.40–5.34.

Distribution. South Africa and Namibia ( Fig. 10 View FIGURE 10 ).
