Diagnosis (based on description of Fain & Lukoschus [1977]). FEMALE ( Fig. 18 ). Subcapitular setae m with 3 tines. Setae vi shorter but subequal in width to e2. Setae e1 and f1 narrow lanceolate. Distances c1-d1 and d1-d2 subequal. Vulvar region without ornamentation. Setae ps3 distinctly developed, slightly curved. Setae ag1 and ag2 subequal. Setae 1b and 1d slightly thicker than 1a. Setae 2a whip-like, much longer than 2b and 3a. Trochanter I with ventral projection and without tubercles. Measurements of holotype ( Fain & Lukoschus 1977): body, including gnathosoma, 375 long, 215 maximum wide. Lengths of setae: d2 70, e2 80, 2a 60, 3a 25, 4a 22.

MALE ( Figs. 19 ). Subcapitular setae m membranous with 3 tines. Genital cone slightly elongated, length/ width ratio 2:1, with straight and parallel lateral margins. Bases of setae vi situated anterior to setae ps2. Setae e2 and f1 short, 4 and 6 times, respectively shorter than e1. Posterior end of opisthosoma with tubercles. Setae 2a whip-like, much longer than 2b. Trochanter I with ventral projection and without tubercles. Measurements of paratype ( Fain & Lukoschus 1977): body, including gnathosoma, 300 long, 180 maximum wide. Aedeagus 120 long. Lengths of setae: si 60 (about 1.7 times shorter than se), e1 60.
