Type material: Holotype male and 1 female ( IZCAS) paratype, CHINA: Guangxi Zhuang Autonomous Region, Lingyun County, Sishui Town, Fulongdong Cave (24º20.786’N, 106º33.476’E, Alt: 470m, T: 16°C, H: 90%), 15 March 2007, Yucheng Lin, Jie Liu leg.

Etymology: The specific name is derived from the Latin semicirculatus, -a, -um, meaning “semicircular”, referring to the shape of the epigynal rims; adjective.

Diagnosis: This new species may be recognised by the following combination of characters: Males — 1. embolus of this new species long, thin, distal part of the embolic apophysis thin; 2. tip of dorsal RTA distinctly widened; 3. dorsal and ventral RTA roughly of the same length ( Figs 6A–F View FIGURES 6 A – H ). Females — 1. lateral margins of epigynal pocket extending beyond median margins anteriorly; 2. posterior part of internal duct system distinctly swollen and larger than anterior part ( Figs 6G–H View FIGURES 6 A – H ). Sinopoda wangi Song & Zhu 1999 is somewhat similar to the new species described here, but may be distinguished in the male sex by having the basal embolus broad, embolic apophysis reduced and the dorsal RTA distinctly longer than the ventral RTA. Females may be distinguished by having anterior and posterior parts of internal duct system of about the same size and epigynal pockets extending more to lateral margins of epigynal field (cf. Jäger et al. 2002: figs 8–9, 13–15).

Palp as in diagnosis. Embolus long and slender, embolus tip extending slightly beyond embolic apophysis, embolus distinctly curved and parallel to the embolic apophysis, proximal part of embolus partly visible. Distal part of the embolic apophysis thin. Sperm duct straight in ventral view. Dorsal RTA bent distally, ventral RTA well developed and pointed in dorsal view.

Copulatory organ as in diagnosis. Median part of epigyne short and narrow. Posterior margin of epigyne slightly bilobate. Internal ducts diverging posteriorly, anterior part as wide to slightly narrower than posterior part ( Figs 6G–H View FIGURES 6 A – H ).
