小鲵科Hynobiidae同物异名及有效种问题的研究

对有属两栖小鲵科Hynobiidae山溪鲵属，巴鲵属，小鲵属分类研究中的同物异名，以及属称和种数订正中的一些分类学问题进行了探讨，无唇褶山溪鲵B. cochranae不是北方山溪鲵Batrachuperus tibetanus的同物异名，巴鲵属是一个有效属称，义乌小鲵Hynobirs yiwuensis应为中国小鲵H.chinensis的同物异名，黄斑拟小鲵Pseudohynobius flavomaculatus可以暂定为秦巴北鲵Ranadon tsinoaensis的同物异名，黑爪异鲵Xenobius melanonychus是滞有效种有待确定。

Study on the Problems of Snonym and Valid Species of the Hynobiidae

Some taxonomic problems of the genus Batrachuperus,Liua and Hynobius are discussed.Based on detail discussion on characters of some species,it is considered that there are six species which belong to the genus,i.e., B.pinchonii,B.tibetanus,B.karlschmidtii,B.yenyuanensis,B.cochranae,and B.longdongensis.Liua Zhao and Hu(1983)is a valid genus.Hynobius yiwuensis Cai(1985)is a synonym of H.chinensis Gunther(1889),Pseudohynobius flavomaculatus Fei and Ye(1982)may be a synonym of Ranodon tsinpaensis Liu and Hu(1966),Xenobius melanonychus Zhang and Hu(1985)may be a valid species,and should be revised after studying in detail.
