Posterior margin of the sternal shield indiscernible. Genital shield flask-shaped, genital sigilla (1–3 pairs) visible, posterior margin of the scutum straight. The 4 th and 5 th pair of genital sigilla clearly visible between the bases of the setae ZV1. The 6 th pair of sigilla posterior or posteroparaxial to the setae ZV1. Ventrianal shield sub-pentagonal, slightly striated, with four pairs of pre-anal setae, JV1, JV2, JV3 and ZV2. Length of the ventrianal shield 125, 126, width at level of setae ZV2 109, 118, at level of setae JV2 102, 110, at level of setae JV3 97, 106 and at level of para-anal setae 85, 87. No solenostome gv3. Setae JV5 smooth, 50, 52 long.

Chelicera. Fixed digit 28, 29 long, with four teeth (three subapical anterior to the pilus dentilis and one posterior to the pilus dentilis). Movable digit, unidentate, 28, 29 long.

Legs. Genu II with seven setae, 2 2/0 2/0 1; Legs IV with three macrosetae, on Sge 23–24, Sti 30 and StIV 48–50.

Insemination apparatus. Major duct broad, cylindrical and very short 2–4. Atrium slightly bulbous, minor duct not visible. A short neck is present between the atrium and the calyx. The calyx is campanulate, thick walled. Calyx U-shaped and elongated, 16–17 long and 6–7 wide.
