疣螈属形态学研究进展及四隐存居群地位的初步确定

Morphological Research Development of Genus Tylototriton and Primary Confirmation of the Status of Four Cryptic Populations

疣螈属已知9种1亚种,其中红瘰疣螈种组物种分布于喜马拉雅山南坡-横段山脉至云贵高原区域,细痣疣螈种组物种沿秦巴山系-武陵山系-大娄山系-南岭山系-北部湾山系和秦巴山系-大别山系分别扩展至我国华东和华南的大部分省区。从2004年起开始对国内的疣螈属物种进行科学调研,经过8年艰苦考察和系统实验,初步对疣螈属物种的形态分化和地理变异进行总结,并发现了3新种和1个新亚种。

Genus Tylototriton has been known to cover 9 species and 1 subspecies, falling into species-groups. The species of Tylototriton verrucosus group is distributed from southern Himalaya Mountain to the Hengduan Mountains and Yuunan-Guizhou Plateau. The species of Tylototriton asperrimus group is spread to most provinces of southern and eastern China in two branches with the first branch distributed from the Qinling-Daba Mountains through the Wuling-Dalou Mountains to the Nanling Mountains and the mountains around Beibu （Tonkin） Gulf and the second branch distributed from the Qinling- Daba Mountains to the Dabie Mountains. Some primary results about the morphological differentiation and geographical variation of Tylototriton have been obtained, and three new species and a new subspecies are found and reported briefly in this paper after an 8-year research since 2004.
