【摘要】 基于40号标本的形态研究,对中国小头蛇属Oligodon进行分类修订。四线小头蛇Oligodon taeniatus(Güther,1861)在中国没有分布,当初发表该纪录所依据的3号标本为紫棕小头蛇指名亚种Oligodon cinereus cinereus(Güther,1864);中国记录的管状小头蛇Oligodon cyclurus(Cantor,1839)应订正为束纹小头蛇Oligodon fascioatus(Güther,1864)。根据色斑、鳞被和半阴茎等综合特征,提出中国记录的喜山小头蛇Oligodon albocinctus包括2个物种,其中云南省陇川县标本为喜山小头蛇Oligodon albcinctus(Cantor,1839),而西藏墨脱县标本是尚未明确的小头蛇属未定种Oligodonsp.,其分类地位有待进一步研究。最后,提供中国分布的小头蛇属物种检索表。更多还原

【Abstract】 We revised the taxonomy of genus Oligodon Boie in China based on 40 specimens. The record of Oligodon taeniatus in China is error,the base of three speciemens from Funing of Yunnan Province is Oligodon cinereus cinereus. The Chinese record of Oligodon cyclurus should be revised to Oligodon fasciolatus. We supported that the record of Oligodon albocinctus in China contains two species based on color,scalation and hemipenial morphology. The specimens from Longchuan of Yunnan Province is Oligodon albocinctus,the specimens from Medog of Tibet is unidentified species which we treated as Oligodon sp. A key to Chinese known species of the genus is provided.更多还原
