Material examined. Namibia: 1 male, Starkberg, Etosha Nat. Park (18°55’S, 15°48’E), 6.v.1987, E. Marais and J. Irish; 1 male, 1 female, 10km NNW Okondeka, Etosha Nat. Park (18°55’S, 15°48’E), 29.iv.1987, J. Irish and E. Marais; 1 female, Halali, Etosha Nat. Park (19°02’S, 16°58’E), 18–20.i.1987, E. Marais and J. Irish; 2 males, Kwando River Susuwe, West Caprivi Park (17°45’37”S, 23°20’55”E), 28.ix.–2.x.1998, A.H.Kirk-Spriggs; 1 male, Elakalapwe, Ovambo (17°24’S, 15°44’E), 20.i.1993, E. Marais (all NMNW).

Description. See Van Stalle (1987: 15; as Oliarus hottentottus ). The specimens from Namibia as well as additional specimens from Angola (ex coll. RMCA) show a small, but distinct variability in male genitalia. In left lateral view, the curved spine emerging from the apex of the periandrium can be semicircular or slightly s-shaped. The straight spine above is variable in its length, and the three larger, dorsal spines are variable in their length (see Figs 37, 38 ).

Distribution. Widely distributed in southern Africa (south of 10°S); see map in Van Stalle (1987: 16). In Namibia, it is only recorded from the northern parts (Etosha, Ovambo, Caprivi).

Ecology. Recorded mainly in the rainy season (October to May).
