Eye sizes: AME 0.55, ALE 0.27, PME 0.10, PLE 0.25. Anterior eye row 1.71 wide, posterior row 2.16 wide, eye area 1.04 long. Chelicera strong, reddish brown, promargin with 3 large teeth and 4 small teeth ( Fig. 7B ); retromargin with 1 tooth and 1 forked fissidentate ( Fig. 7C ). Endite and labium reddish brown. Sternum with iridescent color. Legs yellowish brown. Coxae of legs with a notch at the base. Leg I stout, femur, patella and tibia swollen; tibiae with scopulae ventrally and 2 pairs of stout spines; metatarsi with 2 pairs of stout ventral spines.
