摘　　要：运用形态特征系统聚类和分子系统学分析,研究先前报道的湖南省花臭蛙(Odorrana schmackeri)各地理种群的分类组成及其分布格局。结果显示,原认定的花臭蛙湖南省各地理种群已分化为花臭蛙和黄岗臭蛙(O.huanggangensis)两个物种。分布于湘西南及南部雪峰山和南岭的花臭蛙种群应修订为黄岗臭蛙,为湖南省臭蛙属物种新发现,湘西北及湘东南罗霄山脉的种群为花臭蛙,黄岗臭蛙与花臭蛙在张家界市武陵源景区同域分布。湘西北武陵山与雪峰山之间以及湘中丘陵地带花臭蛙种群的分类归属,黄岗臭蛙和花臭蛙在湖南省分布格局的形成以及同域分布的机制值得探讨。The Piebald Odorous Frogs （Odorrana schmackeri species complex） are endemic to China and widely distribute in Southern China. However, their taxonomy is still unresolved and many cryptic species have been reported in the past decade. Previous analyses have suggested the obvious genetic divergence of O. schmackeri in Hunan Province, whereas the taxonomic status and distribution patterns of this frog in Hunan Province remain unclear. Here, morphological cluster and molecular phylogenetic analyses were conducted based on the data collected from 8 geographical populations of the piebald odorous frog in Hunan and the type locality of piebald odorous frog in Yichang, Hubei as well as samples of the huanggang odorous frog （O. huanggangensis） from the type locality Wuyishan, Fujian （Fig. 1）. The genetic distance between Huitong, Chengbu, Xinning, Shuangpai, Yizhang populations of O. schmackeri in Hunan Province and O. huanggangensis in Fujian Province is 0.001﹣0.002, whereas it reached 0.072﹣0.073 compared with O. schmackeri from the type locality Yichang, Hubei Province. The genetic distance between Shimen, Guidong groups of O. schmackeri in Hunan Province and O. schmackeri of Yichang, Hubei Province is 0.001﹣0.012, which is less than that （0.072﹣0.074） with O. huanggangensis in Fujian Province （Table 2）. Interestingly, the genetic distance analyses further suggested the existence of two distinct species, i.e., O. schmackeri and O. huanggangensis, which corresponding to Wulingyuan （A） group and Wulingyuan （B） group respectively, in the Wulingyuan Scenic Area of Zhangjiajie City, Hunan Province. In addition, the topology of phylogenetic tree reconstructed based on morphological and molecular data all indicated that O. schmackeri species complex in Hunan Province were divided into two major groups： one group consisted of the populations from Wulingyuan （A）, Huitong, Chengbu, Xinning, Shuangpai and Yizhang, the another contained samples from Shimen, Wulingyuan （B） and Guidong �
