Type material: Holotype male, 3 female (all IZCAS) and 1 female ( SMF) paratypes, CHINA: Hainan Province, Dongfang City, Yalong Village, Yalongdong Cave (18°58.72’N, 108°53.41’E), 31 March 2005, Yanjing Song, Xu Han, Yanfeng Tong and Gaoyun Deng leg.

Etymology: The specific name is a compound word and derived from the Latin grandis, -e, meaning “large”, and spinosus, -a, -um, meaning “spinose”, referring to the shape of the branch of RTA; adjective.

Diagnosis: The new species can be separated from other Sinopoda species by 1. unique spine-shaped and small dorsal RTA, 2. distal part of the embolus including the embolic apophysis bent at a right angle, and 3. characteristic lobal pockets situated very close and running parallel to the posterior margin of the epigyne ( Figs 3C–D, 3F View FIGURES 3 A – F ).

Description: Male (holotype). Measurements (in mm): PL 4.5, PW 4.5, AW 2.4, PH 3.5, OL 5.3, OW 3.3.

Palp as in diagnosis. Embolus long and slender, embolus tip as long as embolic apophysis, embolus slightly curved and parallel to the embolic apophysis, proximal part of embolus fully visible. Embolic apophysis long and slender. Sperm duct almost straight in ventral view. Ventral RTA well developed, much larger than dorsal RTA, blunt and long; dorsal RTA arising from the proximal half of ventral RTA. Cymbium distinctly longer than tibia ( Figs 3A–D View FIGURES 3 A – F ).

Copulatory organ as in diagnosis. Median part of epigyne long and narrow with median fissure in posterior part. Posterior margin of epigyne distinctly bilobate. Internal duct system running partly parallel along the median line, anterior part slightly narrower than posterior part. Anterior parts bent at sharp angle, short ( Figs 3E–F View FIGURES 3 A – F ).

Distribution: China (Hainan) ( Fig. 12 View FIGURE 12 ).
