Female (from 38°04'N, 26°07'30''W)): 11, habitus (dorsal); 12, idem (lateral left side); 13, basipodal segment of P4.

Head and 1st thoracic segment with suture weakly marked.
Cephalothorax about 4 times longer than urosome
Corners of thoracic segment 5 rounded, not reaching the midlength of genital segment (extending backward ± 1/3 genital segment).
A1 reaching the midlength of urosome
Coxopodite of P4 with comb of 12 spines across mediodistal portion of posterior surface.
