Singaporemma wulongensis Lin & Li, 2014: 46 , figs 7–9, 17, 20B

Examined material. Holotype ♂, paratypes 8♂ and 20♀ ( NHMSU), CHINA: Chongqing, Wulong, Tudi Town, Tiansheng Village , Xiaodong Cave , 29°31.853'N, 107°50.817'E, altitude 1050 m, 17 October 2010, L. Dou and Y. Lin leg.

Diagnosis. Male of S. wulongensis differs from males of all other congeners with the exception of S. bifurcata by the furcate embolus ( Fig. 6E–e vs. Fig. 6A–D, 6a–d, 6G–H, 6g –h ); it differs from male of S. bifurcata by the narrower, longer oval bulb, the embolus with two equilong tip branches, and the embolus starts from the submesialback surface of bulb, but the embolus of S. bifurcata with asymmetric branches that origins from prolateral surface of bulb ( Fig. 6E–e vs. Fig. 6F–f ). Female of S. wulongensis seems also close to S. bifurcata having a similar vulval structure, but it can be distinguished by the lager “ω”-shaped inner vulval plate, and the longer, weakly sclerotized central process ( Fig. 7F vs. Fig. 7D ).

Description. See Lin & Li, 2014: 46.
