Introduction
The speciose paederine genus Nazeris Fauvel previously included 233 named species and seven subspecies [1]. The genus is distinguished from other paederines particularly by the morphology of the aedeagus, which has a pair of dorso-lateral apophyses [2].
Up to the present, 139 species and one subspecies have been recorded from China. Koch described the first two species, N. chinensis and N. minor from Zhejiang [3]. Ito added 19 species and one subspecies from Taiwan [4–9], and one species from Zhejiang [10]. Zheng described four species from Sichuan [11]. Li (1993) added one species from Anhui in the genus Scopaeus Erichson [12], which was transferred to Nazeris by Frisch [13]. Watanabe et al recorded nine species from Yunnan [14–16]. Hu et al. added 37 species mainly from Zhejiang, Guangxi and Sichuan [17–27]. Assing added 66 species primarily from Yunnan, Sichuan, Gansu and Shaanxi [28–30].
The Luoxiao Mountains range from central to eastern China, extending for about 400 km through Hubei, Hunan and Jiangxi provinces, with several peaks of more than 2000 m. Only two Nazeris species were previously known from this large area: N. inaequalis Assing and N. proiectus Assing. During several recent field trips to this region conducted by the authors and their colleagues, the two known species were collected at their type localities and nearby areas. Besides, twelve undescribed species were discovered. In the present paper, we describe the new species and provide illustrations of their major diagnostic features.
Material and Methods
This study is part of a joint investigation project of biodiversity in the Luoxiao Mountain Range. Apermit was provided by the ministry of Science and Technology of China. The field studies did not involve endangered or protected species.
The type material listed in the present study is deposited in the Insect Collection of Shanghai Normal University, Shanghai, P. R. China (SNUC).
The dissected body parts were mounted in Euparal on plastic slides. The habitus photos were taken using a Canon 7D camera. The photos of the sternites and aedeagi were taken using a Canon G9 camera mounted on an Olympus CX31 microscope.

Eastern Hunan: 1 male, Yanling County, Taoyuandong National Park, 26°29′55″N, 114°02′54″E, along path in mixed forest, leaf litter, sifted, 900 m, 17.VII.2013, Dai, Peng, Xie leg.; 1 female, Yanling County, Taoyuandong National Park, 26°29′44″N, 114°04′39″E, along path in mixed forest, leaf litter, sifted, 1200 m, 18.VII.2013, Dai, Peng, Xie leg.
Distribution and habitat data. The species was found in several localities in the central and southern parts of Luoxiao Shan in western Jiangxi and eastern Hunan (new province record). The specimens were collected by sifting leaf litter in mixed forests, partly together with N. luoxiaoshanus, N. pengzhongi, or N. prominens. The altitudes range from 900 to 1600 m.
Remarks. The male sexual characters of the above material are identical to those illustrated by Assing (2014: figs 53–59) [30].
Nazeris proiectus Assing, 2014.
Material examined. CHINA: Western Jiangxi: 3 males, 3 females, Ji'an City, Jinggang Shan, Bijia Shan, 26°31′08″N, 114°11′22″E, mixed leaf litter, sifted, 400–600 m, 23.VII.2014, Chen, Hu, Lv & Yu leg.; 1 female, Ji'an City, Jinggang Shan, Bijia Shan, 26°31′03″N, 114°11′17″E, mixed leaf litter, sifted, 580 m, 24.VII.2014, Chen, Hu, Lv & Yu leg.
Distribution and habitat data. The species was found only in Jinggang Shan in the southern part of Luoxiao Shan in western Jiangxi. The specimens were collected by sifting leaf litter in mixed forests at altitudes between 400 and 600 m.
Remarks. The species is similar to N. shenshanjiai Hu et al., 2011, from southern Zhejiang province in general appearance and aedeagal characters [24], but can be separated by the abdominal tergites lacking microsculpture, by the posterior margin of male sternite VII having a median projection, and by the dorso-lateral apophyses extending beyond the apex of the ventral process. The sexual characters of the above males are identical to those illustrated by Assing (2014: figs 60–66) [30].
