Description. Male: Cephalothorax ( Figs 67, 68 ) mid orange-brown, darkening to the sides with scattered darker patches on the pars cephalica and distinct bulges on the median sides of PLE ( Fig. 70 ). Faint, darker striae radiating from the foveal area across the pars thoracica. Chelicerae ( Fig. 69 ) orange, straight, expanded and rounded on the median edge with horizontal ripples down the anterior surface. Two small, unevenly sized, promarginal teeth and one small, retromarginal tooth. Endites, labium and sternum orange. Endite distinctively shaped with lateral wing-like extensions.

Ventral abdomen dirty brown with faint darker longitudinal stripes. A thick median lip on the posterior abdomen immediately anterior to the spinnerets. Legs orange-brown, L1 more robust and larger than other legs, with femur darker and vertically flattened and a line of four strong spines on the anterior side of the tibia. Ventral, light coloured, fringe on the patella and tibia of L1 and L2. Palp ( Figs 71–75 ): orange-brown, tibia and cymbium covered with thick long brown hairs.
