Description Female Total length 5.0. Carapace yellow, ocular area slightly darker, pattern with two darker longitudinal brown parallel bands around cephalic area and fovea, clypeus yellow ( Fig. 13A, D ). Sternum surface white, intercoxal triangles present on all legs. Labium brown, white at tip, longer than wide. Endites yellow, rectangular, slightly broader at tip ( Fig. 13C ). Chelicerae yellow, paturon dorsum without pattern ( Fig. 13B, D ), promargin with five teeth, retromargin with eight to nine denticles.

Copulatory openings under straight hood slightly projected at center. Copulatory ducts sclerotized, short, slightly curved, entering spermathecae on lateral surfaces. Seminal receptacles in anterior third in copulatory ducts inconspicuous. Fertilization ducts short, straight, and emerging from lateral surfaces of spermathecae ( Figs 14E–F , 15G–H ).

Coxa III tubercle roughly rectangular with posterior apical spur. Coxa IV with a long, curled spur curved at tip ( Fig. 15E–F ). Median apophysis hook-shaped in ventral view. Embolus long, translucent and filiform ( Figs 14A , 15A ). RTA anterior branch curved with sclerotized margin, apical edge of posterior branch of RTA with two triangular tips ( Figs 14A, C–D , 15A, C–D ). Palpal tibia prolateral apophysis small, conical ( Figs 14B–C , 15B–C ). Pedipalp tibia proportion slightly longer than wide, stridulatory ridges extending from ventral branch of median tegular apophysis to tibial distal margin ( Figs 14A–B, D , 15A–B, D ).
