本文从形态、解剖、生态等方面的证据进一步论证了山溪鲵的Ｂａｔｒａｃｈｕｐｅｒｕｓｔｉｂｅｔａｎｕｓ与Ｂ．ｐｉｎｃｈｏｎｉ是两个有效种，而非同物异名。 相似文献

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。 相似文献

The chromosome number of a Chinese salamander, Batrachuperus pinchonii, was re-examined. Adults and embryonic specimens had a diploid number of 66, with 33 bivalents during meiosis, in contrast
to previous reported results. Furthermore, when C-banding analysis was performed with embryos, chromosomes with banding patterns
homoeologous to those of Salamandrella keyserlingii and Hynobius species were found. It appears, therefore, that Batrachuperus, Salamandrella and Hynobius might be derived from a common ancestral species in eastern Asia.
