Other material examined

SOUTH AFRICA: Free State Province: 1♂: Erfenis Dam Nature Reserve, 28°30.134'S, 26°48.427'E, 21.IX–22.X.2005, pitfalls, burned site 2, C. Haddad, S. Otto & R. Poller (MRAC, prepared for SEM).

Diagnosis

The male of this species can be easily recognised from African congeners by the presence of one or two very large teeth at the fang base (Fig. 13), and the transversely orientated curved embolus with distally broadened conductor bearing a single tooth on its dorsal surface (Figs 42, 43, 57). The raised median ocular tubercle is broader than in the other species.

Etymology

This specific epithet is Latin for southern, referring to the distribution of the species, southernmost in the genus.

Description

Male holotype. Measurements: CL 1.60, CW 1.25, AL 3.15, AW 1.68, TL 6.35 (5.60–7.80). Length of leg segments, and total: I 1.40 + 0.55 + 1.00 + 1.15 + 1.25 = 5.35; II 1.30 + 0.55 + 0.85 + 1.24 + 1.45 = 5.39; III 1.05 + 0.64 + 0.64 + 1.20 + 2.40 = 5.93; IV 1.45 + 0.64 + 0.75 + 1.44 + 2.90 = 7.18. Carapace index 1.28; patella-tibia index 0.97.
Carapace and chelicerae dark brown in colour (Fig. 2). Median ocular tubercle raised, darker in colour; median ocular tubercle broader than in other species. Chelicerae with single prolateral row of teeth, one very large tooth close to fang base, sometimes accompanied by second large tooth, remaining teeth distinctly smaller and subequal in size, with several denticles retrolateral of teeth row close to cheliceral base (Fig. 13). Sternum and coxae pale brown, remainder of legs brown, gradually fading to yellow at tarsi. Legs weakly covered with bristles; prolateral side of patellae, tibiae and metatarsi of legs II–IV covered with spinules. Abdomen grey-brown, with a round brown scutum anteriorly (Fig. 2). Palpal cymbium short with rounded distal margin; embolus and conductor orientated transversely across palpal axis, pointing retrolaterally; conductor broadened distally, with a single small tooth on its dorsal surface distally; embolus long, slightly curved in a S-form along its length (Figs 42, 43, 56–58).
Female. Unknown.

Distribution

Endemic to central and northern Free State Province, South Africa (Fig. 73).

Biology

The species was collected exclusively by pitfalls in spring and early summer (September to early December) in the Grassland Biome of South Africa. Specimens were only collected in dark vertic clay and loamy-clay soils and not from sites with sandy soils. Most of the specimens were collected from sites near to freshwater streams and dams. Despite exhaustive attempts to locate burrows in the vicinity of pitfall sites (Erfenis Dam Nature Reserve and Botanical Gardens) none could be found.
