| 中文摘要: |
| 2020年7月30日，在湖南壶瓶山国家级自然保护区石碾子沟（30°00′46″ N，110°32′18″ E，海拔615 m）采集到1号蛇类标本，经形态鉴定和分子系统关系比较，确定为四川竹叶青蛇（Trimeresurus sichuanensis），为湖南省蛇类分布新记录种，该标本（CSUFT HPS2007080）存放于中南林业科技大学动物标本室。此次发现增补了四川竹叶青蛇的生物学信息，也表明该物种在武陵山脉及其延伸地区可能有着更为广泛的地理分布。建议进一步开展该物种种群生态学的研究，以便为该特有种种群和栖息地保护提供参考。 |
| 英文摘要: |
| Trimeresurus sichuanensis was a newly described species from China in 2011, with only two known localities: Hejiang County, Sichuan Province, and Jiangkou County, Guizhou Province. During our field surveys in July 2020, one adult female Trimeresurus specimen was collected from Hunan Hupingshan National Nature Reserve (HHNNR), Hunan Province, China. After a detailed morphological examination, it exhibits the same characteristics as T. sichuanensis (Table 1), we believed this is a species which never been reported from Hunan Province. We then used four fragments of the mitochondrial genes Cyt b, ND4, 12S rRNA and 16S rRNA to reconstruct the phylogenetic tree of Trimeresurus to identify the position of the newly collected specimen from Hunan Hupingshan National Nature Reserve (Fig. 3). The result shows the HHNNR sample clustered together with the paratype specimen (YBU030116) of T. sichuanensis from Hejiang County, Sichuan Province, and there’s nearly no genetic distance between these two samples. Thus, we here report T. sichuanensis as a new record in Hunan Province, China. Our discovery indicates that a broader distribution range of T. sichuanensis in the Wuling Mountains and nearby areas. In order to provide useful data for the conservation of this endemic species, researches on its potential range and population status should be a focus. |
