Etymology.

The specific name is the full name of Mr. Cheng Wang (Tongren University), one of the collectors of the type specimens; noun (name) in genitive case.

Diagnosis.

Eriovixia wangchengi sp. nov. resembles E. yaoi sp. nov. and also E. jianfengensis by habitus and copulatory organs, but can be distinguished from them by: 1) posterior end of the abdomen with 6 tubercles vs. lacking (Figs 9C-F; Han and Zhu 2010: figs 2B-D); 2) PMEs of male anterior to AMEs in lateral view vs. AMEs anterior to PMEs (Figs 19E, 21D; Han and Zhu 2010: fig. 2D); 3) conductor with a tapered tip, visible in apical view vs. no tapered tip; 4) embolus straight in prolateral view vs. curved (Fig. 9A; Han and Zhu 2010: fig. 9D); 5) spermathecae touching each other vs. separated (Fig. 10D; Han and Zhu 2010: fig. 9A); and 6) scape not keeled vs. keeled (Fig. 10C, Han and Zhu 2010: fig. 9C). The male differs from E. yaoi also by having: 1) a cephalic protuberance vs. absent (Fig. 19E); and 2) long bristles around the eye region vs. absent (Figs 9C-D, 19E)
