中文摘要:
      2022年9月和2023年4月在浙江省温州市鹿城区仰义水库分别采集到1条脊蛇属(Achalinus)物种幼体尸体标本(标本编号分别为2022AZJLCN1和2023AZJLCN2)。形态上它们分别与黄家岭脊蛇(A. huangjietangi)和云开脊蛇(A. yunkaiensis)接近。基于线粒体COI基因片段的最大似然树结果,两蛇样本序列分别与这两种脊蛇聚为一个支系;2023AZJLCN2标本与云开脊蛇的遗传距离为0.10,低于中国境内分布脊蛇属物种间的遗传距离(0.12 ~ 0.16);2022AZJLCN1标本与黄家岭脊蛇的遗传距离为0.09,在黄家岭脊蛇种内遗传距离(0.04 ~ 0.12)范围内。综上,鉴定2023AZJLCN2标本为云开脊蛇,2022AZJLCN1标本为黄家岭脊蛇。此前记录云开脊蛇分布于我国广东和广西,本次在浙江温州市鹿城区的发现为浙江蛇类新分布记录种;黄家岭脊蛇分布于安徽和浙江,此次在在温州市鹿城区的发现是温州市首次新分布记录。这两种脊蛇的新分布记录提示它们有更广的分布范围。
英文摘要:
      Two specimens of genus Achalinus (2022AZJLCN1 and 2023AZJLCN2) were collected from Yangyi Reservoir, Lucheng District, Wenzhou City, Zhejiang Province in September 2022 and April 2023. They were similar to A. yunkaiensis and A. huangjietangi in morphology, respectively. The results of the maximum likelihood tree based on COI gene sequences showed that they were clustered into a clade with these two species respectively. The p-distance of 2023AZJCN2 and A. yunkaiensis was 0.10, lower than that between Achalinus species ranging from 0.12 to 0.16 in China. The p-distance of 2022AZJLCN1 and A. huangjietangi was 0.09, which is not higher than that between A. huangjietangi ranging from 0.04 to 0.12. In the end, 2023AZJLCN2 and 2022AZJLCN1 were identified as A. yunkaiensis and A. huangjietangi. The previous record of A. yunkaiensis was found in Guangdong and Guangxi of China, the discovery in Lucheng District is a new record in Zhejiang Province. And A. huangjietangi was distributed in Anhui and Zhejiang Provinces, the discovery in Lucheng District is the first new record of its distribution in Wenzhou City. The new records of those two species suggested a wider distribution range.
