Singaporemma banxiaoensis Lin & Li, 2014: 42 , figs 4–6, 16C–D, 20A

Examined material. Holotype ♂, paratypes 1♂ and 1♀ ( IZCAS), CHINA: Guangxi, Pingxiang, Xiashi Town, Xinming Village , Banxiaotun , Banxiao Cave , 22°5.542'N, 106°52.148'E, altitude 175 m, 26 July 2011, X. Wang leg.

Diagnosis. Male of this species is similar to S. halongense ( Fig. 6A ) and S. lenachanae ( Fig. 6D ), but can be distinguished from the latter two by the narrower, pointed embolic tip ( Fig. 6b vs. Fig. 6a, 6d ), and by the vestigial white eyespots lacking black ocular base in the both sexes (see Lin & Li, 2014: fig. 4G–H vs. Lin et al., 2017: figs 16E–F, 21A). Female is close to S. takensis sp. n. in having a similar configuration of vulva, but differs from the latter by the inverted triangular inner vulval plate, the wider, shorter central process ( Fig. 7C vs. Fig. 5C–D ).

Description. See Lin & Li, 2014: 42.

Distribution. China (Guangxi) ( Fig. 10 ).
