Sinoalaria nitida (Zhao & Li, 2012) comb. nov.

Figs 11 , 17

Karstia nitida Zhao & Li, 2012: 20, figs 11A-E, 12A, B (♀).

Material examined.

Paratype 1♀ (IZCAS), China: Guangxi: Hechi City, Jinchengjiang District, Hechi Town , Laba Village , Shoushui Cave , 24°41.229'N, 107°52.609'E, 268 m, 31.III.2011, Z. Chen and Z. Zha leg. Examined.

Diagnosis.

Sinoalaria nitida morphologically is similar to S. shuidi sp. nov. by the scape shorter than length of epigynal plate, with a swollen apex (Figs 11C-E , 14C-E ) (scape longer than length of epigynal plate, distally not swollen in all other congeners, such as S. chengguanensis , S. chi sp. nov., S. shenhei sp. nov. and S. xiaotu sp. nov.; Figs 6E, F , 8E, F , 13E, F , 16E, F ). From S. shuidi sp. nov., S. nitida can be distinguished by the following features: (1) the scape shaped like a nose, apex nearly as wide as stem (shaped like a water drop, apex distinctly wider than its stem in S. shuidi sp. nov.) (cf. Fig. 11C-E and Fig. 14C, D ); (2) the spermathecae peanut-shaped (globular in S. shuidi sp. nov.) (cf. Fig. 11E, F and Fig. 14E ).

Description.

See Zhao and Li (2012). Habitus as in Fig. 11A, B , epigyne as in Fig. 11C-G .
