Figs 2E–F , 9C–D and 12

Type material: Holotype female, 1 female paratype ( IZCAS), CHINA: Guangxi Zhuang Autonomous Region, Mashan County, Guling Township, Yangyu Village, Jinlundong Cave (23º33.378’N, 108º15.732’E, Alt: 210m, T: 14°C, H: 90%), Yucheng Lin, Jie Liu leg.

Etymology: The specific name is derived from the Latin crassus, -a,-um, meaning “stout”, referring to the shape of the vulva; adjective.

Diagnosis: This new species (females) can be recognised by the following combination of characters: 1. anterior part of median epigynal field about 1/6 to 1/7 of epigynal width, 2. epigynal pockets slightly rounded, diverging posteriorly, 3. internal duct system wider than long, with anterior part slightly wider than posterior part, 4. anterior part with additional asymmetrical sclerotised structure ( Figs 2E–F ).

Description: Female (holotype). Measurements (in mm): PL 7.5, PW 6.4, AW 3.9, PH 5.2, OL 7.8, OW 4.5.
