Colour: Prosoma dark brown with light brown stripe around fovea widening toward posterior part. Chelicerae brown. Sternum brown. Legs yellow but coxae greenish­brown. Opisthosoma dorsally brown with two larger anterior whitish spots, ventrally pale with few brown spots. Palp ( Figs 12 View FIGURES 9–12 ): tibia with broad apophysis, sharp on retrolateral side, cymbium oval with four distal spines. Tegulum strongly developed. Embolus long, slightly curved in the middle. Median apophysis long terminally hook­shaped, conductor hooked, distal tegular apophysis with paired protuberances.

Female: Total length 8.71 mm, prosoma 4.03 mm long, 2.61 mm wide. Cephalic part of prosoma not tapering. Colour: Prosoma yellow­brown. Legs yellow but coxae and femora greenish­brown.
