Legs light yellow-orange (143M); claws not pectinated; tibia I–IV with one dorsal macrosetae; metatarsus I with dorsal trichobothrium, Tm I 0.48– 0.50; Tm IV absent. Palpus length: 0.14–0.17. Palpal tibia with two retrolateral trichobothria ( Fig. 31 ), with one large palpal tibial apophysis (PTA) bearing two small teeth ventrally ( Fig. 31 ) curving into a rugose process ( Fig. 33 ); paracymbium C-shaped bearing 5 setae basally ( Fig. 31 ); embolic division simple, embolus (E) short, flat, curving apically ( Figs 30, 34 ); embolic membrane (EM) present ( Fig. 34 ); tailpiece (TP) elongated, projecting basally ( Fig. 34 ); tegulum (T) large, protruding ventrally ( Fig. 30 ); protegulum (PT) large with scale-like protegular papillae ( Figs 30, 34 ); suprategulum (SPT) bearing tooth-like marginal suprategular apophysis (MSA) ( Fig. 34 ). Female (n=5) : Total length: 1.25–1.45; carapace length: 0.62–0.64; carapace width: 0.46–0.48; carapace coloration as in male, shiny, finely reticulate, hairless except for a row of 4 long, forward-pointing setae extending from dorsal groove to posterior eye row and a few setae in eye area. Coloration of sternum and chelicerae as in male, promargin with 5 teeth, retromargin with 5 denticles; cheliceral stridulatory organ visible, with ~ 16 striae. Abdomen as in male. Legs coloration as in male; tibia I–IV with one dorsal macrosetae; metatarsus I with dorsal trichobothrium, Tm I 0.50–0.52; Tm IV absent. Palpal claw absent. Epigynum width: 0.12–0.15. Epigynal ventral plate with large, arched slit where the copulatory openings (CO) are located ( Figs 35, 36 ); copulatory ducts (CD), large, curved and narrowing down into two loops ( Figs 36, 37 ); spermathecae (S) oval ( Figs 35, 37 ); fertilization ducts (FD) long and sinuous ( Fig. 37 ).
