CEPHALOTHORAX: Carapace dark brown, shiny, finely reticulate; suffused with dark gray along margin, radiating lines; trident mark present. Sternum brown strongly suffused with dark gray. Clypeus height 2. Chelicerae orange-brown, apical part lighter, strongly excavated; ~12 seta-tipped tubercles; promargin two denticles, retromargin three denticles, both margins with rounded projections near base of fang ( Fig. 26 ). Cheliceral stridulatory organ ~37 striae, well spaced throughout. ABDOMEN: Uniformly dark gray. LEGS: Yellow-orange; leg I total length: 2.82; leg III total length: 2.13; Tm I: 0.24, Tm IV: absent. GENITALIA: Palpal retrolateral tibial apophysis short, rugose; dorsal tibial apophysis wide, rugose; two retrolateral trichobothria and a dorsal one ( Fig. 130 ). Cymbium triangular; glabrous depression present ( Fig. 130 ); dorsal cymbial tubercle triangular, smooth; ventral cymbial tubercle absent; prolateral notch shallow ( Fig. 131 ). Paracymbium apical pocket short, anterior and posterior pockets short and curved ( Fig. 130 ). Embolus tip pointed, concave; dorso-ventrally spiny; basally with two spurs; Fickert’s gland absent; ventral lamella serrated, transparent; thumb short reaching well below the embolus proper ( Fig. 132 ). Embolus proper set apically, dorsal part wider and serrated ( Fig. 132 ). Anterior terminal apophysis narrow with long protrusions; posterior terminal apophysis wide, striate; lamella characteristica large, margin dentate basally, ending in four large spikes ( Fig. 133 ). Female : Total length 2.16; carapace length 0.81, width 0.63. CEPHALOTHORAX: Same coloration as male. Chelicerae yellow; promargin four teeth, retromargin five denticles.

GENITALIA: Epigynum with wide proximal part of scape, sides straight and vertical; epigynal slits oval and short; pit hook depression deep ( Fig. 134 ); lateral lobes wide and short; stretcher seemingly absent ( Fig. 135 ). Median part of scape long and wide with constrictions; genital pores situated at base of lateral lobes pockets ( Fig. 136 ). Internal genitalia with a rounded ventral receptacula and a small, oval dorsal one ( Figs 135, 136 ).
