Comment. The same as the former synonymy, N. chinensis and N. tianmuensis were described from the same locality (Tianmushan, northwest Zhejiang Province, east China) and with the same characters after the types were examined. N. tianmuensis is a new synonym of N. chinensis .

Comparative notes. Nazeris chinensis is similar to N. sadanarii Hu & Li, 2010 and N. zhujingwenae Hu, Li & Zhao, 2011 in external characters. It can be separated from N. sadanarii by the ventral surface of head lacking microsculpture ( Fig. 15 ), the male sternite VII lacking stout black setae, and much shorter dorso-lateral apophyses of aedeagus ( Figs. 7, 8 ). It can be separated from N. zhujingwenae by all of the abdominal tergites with fine microsculpture, and by the shorter dorso-lateral apophyses of aedeagus ( Figs. 7, 8 ).

Distribution and habitat data. The species is known from northwest Zhejiang. The specimens were collected by sifting leaf litter at altitudes of 1000–1750 m, partly together with N. minor and N. rougemonti .
