Type material.

Holotype male. SENEGAL: Dakar [14°45'N, 17°20'W], MNHN 8062 (examined).

Other material examined.

SENEGAL: Sonkorong [13°46'N, 15°33'W], near Kaymor, leg. A. Russell-Smith, 14.VI.1994 (leaf litter, 20 year old fallow), 4♂ (BMNH); Thyssé Region, Forêt Classé de Ngayene [13°43'N, 15°27'W], leg. A. Russell-Smith, 24.VII.1996 (leaf litter), 1♂ 3♀ (BMNH).

Diagnosis.

This species is recognised by the distinctly coiled epigynal ridges and the oblique curved entrance ducts of the females (Figs 89, 90). Males can be recognised by the broad, somewhat flattened embolus (Figs 43, 56).

Remarks.

The right leg I and right palp of the male holotype are missing. The redescription of the male is provided for the holotype, although more recently collected specimens are darker brown in colour.
