Holotype: male, SOUTH AFRICA, Limpopo Province, Entabeni , 05, 22°58'S: 30°16'E, night collecting, exposed afromontane forest, 9 February 2008, leg. S.H. Foord, N. Hahn, M. Muthaphuli & M. Mashau ( NCA 2012 /2706). GoogleMaps  

Diagnosis. This species is similar to R. virilis   described below. It may be distinguished by the presence of a ventral process on the palpal tibia (the only species in the genus with this process). It also differs in the pedipalp structure; the bulb is wider than the cymbium (narrower in R. virilis   ) and the embolus is clearly longer with the distal part perpendicular to the long axis of the cymbium (versus parallel in other species).

Etymology. The specific name refers to the presence of a protuberance on the ventral surface of the palpal tibia.

Description. Measurements. Cephalothorax: length 1.7, width 1.4, height 1.1. Abdomen: length 1.7, width 1.3. Eye field: length 0.8, anterior and posterior width 1.3.

Male. General appearance as in Fig. 142 View FIGURES 142–145 . Carapace moderately high, sloping posteriorly, dark brown with white hairs on lateral slopes. Ocular area dark brown, almost black. Sternum brown. “Cheeks”, clypeus and chelicerae dark brown, with dense white hairs on clypeus and cheeks. Chelicerae with two promarginal teeth and a broad retrolateral tooth ( Fig. 143 View FIGURES 142–145 ). Abdomen yellowish brown; dorsum brownish with yellow longitudinal central patch and large light area on posterior half. Sides whitish, venter light ( Fig. 142 View FIGURES 142–145 ). Book-lung covers and spinnerets brown. Legs brown, distal segments lighter, tarsi yellow. First legs stouter than others, with dark brown tibiae, covered with long dense dark hairs ventrally. Pedipalps dark brown clothed in dark brown hairs. Tibia with large process on ventral surface, tibial apophysis pointed, bulb with short proximal lobe, embolus wide at base, its tip rolled together with tip of terminal apophysis and perpendicular to long axis of cymbium ( Figs 144, 145 View FIGURES 142–145 ).
