Description: Male : Total length 2.02; carapace length 0.91, width 0.70. CEPHALOTHORAX: Carapace orange-brown, shiny, finely reticulate; suffused with dark gray along margin and radiating lines; trident mark present. Sternum orange-brown suffused with dark gray. Clypeus height 3. Chelicerae orange-brown, strongly excavated; ~12 seta-tipped tubercles; promargin three teeth, retromargin four denticles, promargin with large triangular projection near base of fang, retromargin with truncated projection. Cheliceral stridulatory organ ~29 strong striae, well spaced, slowly getting closer basally. ABDOMEN: Uniformly gray. LEGS: Orange; total length leg I: 3.44, total length leg III: 2.50; Tm I: 0.21, Tm IV: absent. GENITALIA: Palpal retrolateral tibial apophysis elongated, tip rounded, with a spike medially; dorsal tibial apophysis wide and smooth; two retrolateral trichobothria and a dorsal one ( Fig. 485 ). Cymbium triangular; glabrous depression present ( Fig. 485 ); cymbial tubercles absent; prolateral notch shallow ( Fig. 486 ). Paracymbium apical pocket short, anterior and posterior pocket absent, with one spine posteriorly ( Fig. 485 ). Embolus tip pointed, with large “swirled element”; Fickert’s gland medial, elongated; ventral lamella transparent, large and spiny with two large prongs basally, joining the thumb; thumb short, reaching well below the embolus proper ( Fig. 487 ). Embolus proper set apically on a horizontal ridge associated with the embolus tip, dorsal part slightly wider ( Fig. 487 ). Anterior terminal apophysis wide, tip with long protrusions; terminal apophysis narrow and blunt; lamella characteristica small, one narrow, one large triangular tip ( Fig. 488 ). Female : Total length 1.69; carapace length 0.80, width 0.64. CEPHALOTHORAX: Same coloration as male. Chelicerae orange; promargin five teeth, retromargin five denticles. Cheliceral stridulatory organ ~29 striae, well spaced slowly getting closer basally. ABDOMEN: Same as male. LEGS: Same as male; palpal claw absent; total length leg I: 3.46, total length leg III: 2.55; Tm I: 0.27, Tm IV: absent. GENITALIA: Epigynum with proximal part of scape wide, sides parallel; epigynal slits small; pit hook depression shallow ( Fig. 489 ); lateral lobes elongated and folded; stretcher small; pit deep ( Fig. 490 ). Median part of scape narrow; genital pores situated at base of lateral lobes pockets ( Fig. 491 ). Internal genitalia with large, oval receptacula obliquely positioned ( Figs 490, 491 ).
