Description of female. Prosoma. Frontal organ with two elongated and granulated branches, 2.1 times longer than wide (28, long and 13, wide). Lateral organ with one pointed, granulate blade, 1.9 times longer than wide (28/ 15). Propeltidium with 10 + 10 short setae. Metapeltidium with 3 + 3 setae, t1 (25) much shorter than t2 (98) and t3 (65). Hand of chelicera with 6 dorsal and one ventral seta, each finger with 9 teeth. Basal segment of the chelicera with three setae in the distal series (d1-d3): d3> d2> d1; d1 thing, tapering and with small setules along its length, 53 long. d2 and d3 thickened, with subparallel borders, tiny setules and a truncated tip; d2 with a crown of spines on the truncated tip; d2 and d3 95 and 60 long, respectively ( Fig. 1 View FIGURE 1–6 ). Sternum with 11 deuto-tritosternal setae.
Chaetotaxy of coxae. Pedipalp coxa with 19 setae of different lengths ( Fig. 2 View FIGURE 1–6 ). Coxa I with 15 setae: 13 normal setae and two microsetae ( Fig. 3 View FIGURE 1–6 ). Coxa II with 12 setae: 3 thickened and 9 normal setae ( Fig. 4 View FIGURE 1–6 ). Coxa III with 11 setae: 3 thickened setae, one long macroseta and 7 normal setae ( Fig. 5 View FIGURE 1–6 ).
