Epanerchodus lipsae Golovatch and Geoffroy, 2014: 102 , figs 17–20, map 3.

Material examined: 6 males, 8 females ( SCAU) from China, Sichuan Province, Mianyang City, Beichuan County, Xunlongshan Mountain , Wolong Dong Cave , 15.VII.2014 ; 8 males, 26 females ( SCAU) from the same county, Yuanwang Dong Cave , 16.VII.2014 ; 10 males, 19 females ( SCAU) from Sichuan Province, Jiangyou City, Hanzeng Town, Shuimen Dong Cave , 19.VII.2014, colls: Weixin Liu , Haomin Yin , Sunbin Huang and Xinhui Wang.

Notes: This species is diagnosed by the gonopod showing a peg-shaped exomere (ex) and a ribbon-shaped endomere (en). The endomere has an axe-shaped mesal process (p) and a long, flagelli- or spiniform process (a) at its base ( Fig. 19 ). Epanerchodus lipsae has been described from a few caves in Jiangyou and Beichuan counties in northeastern Sichuan Province. The material examined here comes from several additional caves and agrees with the original description in morphological characters ( Golovatch & Geoffroy 2014); only the body length is more variable in these specimens: ca 16–28 vs. 22–26 mm.
