Description: Male : Total length 1.73; carapace length 0.75, width 0.57. CEPHALOTHORAX: Carapace orange-brown, shiny, finely reticulate; suffused with dark gray along margin, radiating lines; trident mark often present. Sternum brown strongly suffused with dark gray. Clypeus height 3. Chelicerae orange-brown, excavated; seta-tipped tubercles absent; promargin four denticles, retromargin four denticles; without projections near base of fang. Cheliceral stridulatory organ ~64 striae, narrowly spaced throughout. ABDOMEN: Uniformly dark gray. LEGS: Orange; leg I total length: 2.29; leg III total length: 1.78; Tm I: 0.29, Tm IV: absent. GENITALIA: Palpal retrolateral tibial apophysis with one small, rugose pointed tip; dorsal tibial apophysis rounded and rugose; two retrolateral trichobothria and a dorsal one ( Fig. 151 ). Cymbium triangular; glabrous depression present ( Fig.151 ); dorsal cymbial tubercle wide, rounded and smooth; ventral cymbial tubercle absent; prolateral notch absent ( Fig. 152 ). Paracymbium apical pocket long, anterior pocket curved, long and deep, posterior pocket short and curved ( Fig. 151 ). Embolus tip pointed, straight; apico-ventrally with spines; basally with small spines; Fickert’s gland absent; ventral lamella narrow, slightly serrated; thumb short reaching below the embolus proper ( Fig. 153 ). Embolus proper set apically, dorsal part narrower ( Fig. 153 ). Anterior terminal apophysis narrow with few long protrusions; posterior terminal apophysis striate; lamella characteristica large and elongated, with several rounded tips ( Fig. 154 ). Female : Total length 1.65; carapace length 0.66, width 0.50. CEPHALOTHORAX: Carapace light yellow, suffused with dark gray along margin, radiating lines. Clypeus height 1. Sternum suffused with dark gray. Chelicerae yellow; promargin five teeth, retromargin five denticles. Cheliceral stridulatory organ ~30 striae, well spaced apically slowly getting closer basally. ABDOMEN: Uniformly light gray. LEGS: Yellow; leg I total length: 2.21; leg III total length: 1.64; tarsal claw absent; Tm I: 0.25, Tm IV: absent. GENITALIA: Epigynum with wide proximal part of scape, narrowing evenly; epigynal slits oval; pit hook depression very shallow ( Fig. 155 ); lateral lobes wide and short, folded apically; stretcher small; pit deep ( Fig. 156 ). Median part of scape wide and short; genital pores situated at base of lateral lobes pockets ( Fig. 157 ). Internal genitalia with large rounded ventral and dorsal receptaculas ( Figs 156, 157 ).
