摘　　要：【目的】考察"台湾钝头蛇-中国钝头蛇复合体"(Pareas formosensis-chinensis complex,后简称"复合体")分类的历史、现状及进展。【方法】主要依据最新文献资料及色斑、鳞被特征等形态学资料,对"复合体"的分类进行探讨。【结果】1)分子系统学研究恢复了中国钝头蛇(Pareas chinensis)的分类地位,它的分布范围可能仅局限于四川省及邻近省份;2)综合分类研究恢复了阿里山钝头蛇(Pareas komaii)的分类地位,并设立新种泰雅钝头蛇(Pareas atayal);3)根据形态特征,云南钝头蛇(Pareas yunnanensis)应为有效种;4)台湾钝头蛇(Pareas formosensis)、广东钝头蛇(Pareas kuangtungensis)、缅甸钝头蛇(Pareas hamptoni)可能是亚种关系。【结论】"复合体"并非1个种,最少应包含5个种。综合分类学方法为解决本类群的的分类争议提供了方向。[Purposes]It aims to investigate the history,status and development of the classification of Pareas formosensis-chinensis complex.[Methods]Based on literature survey and morphological characteristics,the classification status of the ＂complex＂was discussed.[Findings]1）The molecular phylogenetics results indicate that Pareas chinensis is a valid species.2）Using integrated taxonomic method,the taxonomic status of Pareas komaii was recovered,and a new species was described.3）According to the morphological characteristics,Pareas yunnanensis should be an effective species.4）Pareas formosensis,Pareas kuangtungensis and Pareas hamptoni may be a subspecies relationship.[Conclusions]P.formosensis-chinensis complex is not one species,but should contain at least five species.
