One juvenile and one adult female wolf snake(Colubridae: Lycodon) were sampled at Yixian and Fuxi, Huangshan, Anhui, China in the summer of 2011 and 2012, respectively. The two specimens were identified as Lycodon liuchengchaoi based on external morphology and molecular data. This is a new reptile record in Anhui Province. In our laboratory, four eggs were laid and three neonates were hatched successfully. This is the first record of the laying and incubation of L. liuchengchaoi eggs. The five specimens were deposited at the Museum of Huangshan University(HUM20140001) and Guangdong Entomological Institute(HB-lcfsp12613, HB-lcfsp-ch1~3). 相似文献

Classification of the Asian snake genera Lycodon and Oligodon has proven challenging. We conducted a molecular phylogenetic analysis to estimate the phylogenetic relationships in the genus of Lycodon and clarify the taxonomic status of Oligodon multizonatum using mitochondrial(cyt b, ND4) and nuclear(c-mos) genes. Phylogenetic trees estimated using Maximum Likelihood and Bayesian Inference indicated that O. multizonatum is actually a species of Lycodon. Comparing morphological data from O. multizonatum and its closest relatives also supported this conclusion. Our results imply that a thorough review of the evolutionary relationships in the genus of Lycodon is strong suggested. 相似文献

2021年9月,在贵州省黔南布依族苗族自治州荔波县黎明关水族乡采集到一雌一雄2号白环蛇属(Lycodon)物种个体,两个体具有以下形态学特征:背鳞17-17-15行,光滑;上唇鳞8枚,下唇鳞10枚;颊鳞1枚,入眶;眶前鳞1枚,眶后鳞2枚;颞鳞8枚,2 + 3 + 3排列;腹鳞209 ~ 213枚(+ 1或2枚前腹鳞),雄性尾下鳞90对,雌性标本尾末端缺损,肛鳞完整。活体背面棕黑色,雄性体背部具29条浅色环,尾背部具12条浅色环,雌性体背部具30条浅色环,尾背部具10条浅色环。2号标本与锦白环蛇(L. pictus)原始描述中提供的形态学鉴定依据相符。线粒体Cyt b基因序列分析显示,本次采集的标本与已知锦白环蛇样本的遗传距离在0.3% ~ 0.8%之间。综合形态特征和系统发育分析比较,鉴定此次采集的白环蛇属标本为锦白环蛇,为贵州爬行动物分布新记录种。 相似文献

2017年6月23日,在河南内乡开展两栖爬行动物调查采集,于伏牛山南坡的宝天曼国家级自然保护区 (111°53′1.76″E,33°29′9.58″N, 630m a.s.l.) 采集到1号游蛇科(Colubridae)链蛇属Lycodon标本,经鉴定为刘氏链蛇L. liuchengchaoi, 采集环境见图1。该物种是河南省爬行纲新纪录种(Zhang et al., 2011; Uetz et al.,2018)。标本整体用75%乙醇溶液固定,保存于河南大学生命科学学院标本室。 相似文献
