description: Austrachelas pondoensis n. sp.
(Figs 9, 10, 16–35, 42–49, 68–71)
Diagnosis. This is the largest species in the genus, and females can be easily distinguished by the shape of the anterior epigynal hood and the widely separated spermathecae (Figs 31, 68, 69); males can be recognised by the large partially hidden triangular lobe distally on the embolus and the denticulate retrolateral tibial apophysis (Figs 29, 70, 71).
Etymology. This species is named after the Pondoland region in the Eastern Cape Province, South Africa.
Female. Measurements: CL 5.18–6.05, CW 3.70–4.28, FL 0.40–0.48, AL 6.50–9.20, AW 3.10–5.13, SL 2.88–3.05, SW 2.00–2.27, TL 11.80–15.30, AME–AME 0.08, AME–ALE 0.04, ALE–ALE 0.60, PME–PME 0.10, PME–PLE 0.22, PLE–PLE 0.89.
Length of leg segments (sequence from femur to tarsus, and total): I 3.95 + 2.38 + 2.95 + 2.12 + 1.38 = 12.78; II 3.50 + 2.10 + 2.58 + 2.05 + 1.28 = 11.51; III 2.78 + 1.65 + 1.70 + 2.32 + 1.05 = 9.50; IV 4.07 + 2.10 + 3.08 + 3.72 + 1.20 = 14.17.
Carapace deep red-brown, slightly paler medially (Fig. 9); AER strongly procurved, laterals larger than medians; AME separated by distance equal to ½ their diameter, AME separated from ALE by distance equal to ¼ AME diameter; clypeus height equal to 1½ AME diameter at AME, equal to 1¼ ALE diameter at ALE; PER straight, laterals larger than medians; PME separated by distance equal to ½ their diameter, PME separated from PLE by distance equal to 1¼ PME diameter. Chelicerae deep orange; promargin with three teeth, proximal tooth smallest, median tooth largest; proximal and median teeth closer to each other than to distal tooth; retromargin with two small denticles, situated either side of distal promarginal tooth. Legs all deep orange in colour, slightly paler distally.

Abdomen dark grey dorsally, with mottled pale grey chevron (Fig. 9), paler grey laterally and ventrally; dorsum and venter lacking scutum or other sclerites. Female epigyne with short narrow anterior hood and small lateral hoods (Figs 31, 68); copulatory openings laterally situated, entering ST 2 via narrow entrance ducts; ST 2 small, globose, connected broadly to widely separated elongate oval posterior ST 1 (Fig. 69).
