Sternum brown, suffused with grey. Chelicerae light brown, promargin with 1 large and 4 small teeth, retromargin with 4 denticles. Cheliceral stridulatory organ not visible. Abdomen uniformly coloured, light to dark grey, densely covered with decumbent hairs. Legs light yellow, tibia I–IV with one dorsal macroseta; metatarsus I with dorsal trichobothrium, Tm I 0.52–0.62, metatarsus I with 7 curved megaspines, Tm IV absent. Palpal tibia rather long and acuminate, bearing a small curved sclerotized apophysis on the ectal side ( Figs 13, 14 ); embolic division rather simple, embolus tip spine-like, tailpiece elongate and projecting basally, tegulum (T) rather large, protegulum with protegular papillae, suprategulum well sclerotized, distal suprategular apophysis (DSA) sclerotized becoming membranous, fundus visible ( Figs 11, 12 ); paracymbium small, bearing 2 short setae ( Fig. 13 ). Female (n=5) : Total length: 1.28–1.44; carapace length: 0.50–0.63; carapace width: 0.44–0.50; carapace coloration as in male, 4–5 erect setae along midline. Coloration of sternum and chelicerae as in male; promargin of chelicerae with 1 large and 4 small teeth, retromargin with 5 denticles. Cheliceral stridulatory organ not visible. Abdomen as in male. Legs coloured as in male, tibia I–IV with one dorsal macroseta; metatarsus I with dorsal trichobothrium, Tm I 0.52–0.60, Tm IV absent. Female epigynal plate well sclerotized, somewhat rectangular ( Fig. 15 ); posterior edge of ventral plate U-shaped covering less than half the dorsal plate; spermathecae rounded situated each side of the junction of ventral plate and dorsal plate ( Figs 15, 16 ); copulatory ducts comma-shaped and well separated ( Figs 16, 17 ).
