Bonn zoological Bulletin 62 (2): 125 –170 December 2013 On the Nazeris fauna of China II. New species and records from Zhejiang, Sichuan, and Yunnan (Coleoptera: Staphylinidae: Paederinae) Volker Assing Gabelsbergerstr. 2, D-30163 Hannover, Germany; E-mail: [email protected]. Abstract. Material of the Palaearctic paederine genus Nazeris Fauvel, 1873 from the Chinese provinces Zhejiang, Sichuan, and Yunnan is revised. Thirty species are described and illustrated, eight of them from Sichuan and the remainder from Yunnan: Nazeris bilamellatus sp. n. (Sichuan: Emei Shan); N. foveatus sp. n. (Sichuan: Erlang Shan); N. appendiculatus sp. n. (Sichuan: Daxue Shan); N. puetzi sp. n. (Sichuan: Erlang Shan); N. cornutus sp. n. (Sichuan: Erlang Shan); N. tri - furcatus sp. n. (Sichuan: Xiaoxiang Ling); N. wrasei sp. n. (Sichuan: Xiaoxiang Ling); N. schuelkei sp. n. (Sichuan: Laba - he, Daxiang Ling); N. wuliangicus sp. n. (Yunnan: Wuliang Shan and adjacent mountain range); N. nivimontis sp. n. (Yun - nan: Xue Shan N Lincang); N. sagittifer sp. n. (Yunnan: Ailao Shan, Wuliang Shan); N. secatus sp. n. (Yunnan: Laobie Shan); N. cangicus sp. n. (Yunnan: Diancang Shan); N. aculeatus sp. n. (Yunnan: Jizu Shan); N. zhemoicus sp. n. (Yun - nan: Zhemo Shan); N. pungens sp. n. (Yunnan: Xue Shan ENE Lincang); N. lanuginosus sp. n. (Yunnan: Laobie Shan); N. peniculatus sp. n. (Yunnan: mountain range N Er Hai); N. barbatus sp. n. (Yunnan: Wuliang Shan); N. firmilobatus sp. n. (Yunnan: Gaoligong Shan); N. spiculatus sp. n. (Yunnan: mountain range E Luxi); N. curvus sp. n. (Yunnan: Gaoligong Shan); N. infractus sp. n. (Yunnan: Nu Shan); N. subdentatus sp. n. (Yunnan: Gaoligong Shan); N. meilicus sp. n. (Yun - nan: Meili Xue Shan); N. vexillatus sp. n. (Yunnan: Gaoligong Shan); N. circumclusus sp. n. (Yunnan: Gaoligong Shan); N. hastatus sp. n. (Yunnan: Gaoligong Shan); N. bangmaicus sp. n. (Yunnan: Bangma Shan); N. fissus sp. n. (Yunnan: Ailao Shan, Wuliang Shan). Records of 17 additional species are reported. Seven of them are represented exclusively by females and probably undescribed, and the remainder described previously; the latter are from Zhejiang (two species), Sichuan (four species), and Yunnan (four species). The male sexual characters of some of the previously described species are illustrated. Species group affiliations are discussed. The distributions of 37 species are mapped. The genus now in - cludes a total of 171 species and seven subspecies; 94 species have been reported from China (exclusive of Taiwan). Key words.

INTRODUCTION According to a recent contribution (Assing 2013a), the Henan (1). The sum of species exceeds 64 in this overview paederine genus Nazeris Fauvel, 1873 has an essentially because five species have been reported from more than Palaearctic distribution and previously comprised a total one province or from the border region between two or of 143 species and seven subspecies.

Recent studies on the Chinese Lathrobium fauna re - vealed that the diversity in Yunnan (60 described species) ReSUlTS is far greater than that of any other province and that Sichuan (39 described species) ranks second (Assing Diversity and zoogeography 2013b, c; Peng et al. 2013a); among the remaining provinces the Lathrobium fauna of Shaanxi (20 described The revised material is composed of 47 species, ten of species) is the most diverse, but still hosts much fewer them described previously from Zhejiang (two species), species than Yunnan and Sichuan.
