短腿蟾属(无尾目:角蟾科)复查并恢复平头短腿蟾的有效性及描述一新种

Review of the genus Brachytarsophrys (Anura: Megophryidae), with revalidation of Brachytarsophrys platyparietus and description of a new species from China

  • 摘要: 最近,关于广义角蟾属有诸多分类争论,其中也包括单系群短腿蟾。短腿蟾具有明显的可识别的形态特征,且最近所有分子系统学研究都表明其为一个稳定的单系群,因此将其作为一个独立属是合理的。本研究对该属做了全面复查,并基于形态学差异和系统发育关系提出了两个种组,同时认为平头短腿蟾是一个有效种,其与宽头短腿蟾有较大遗传分化和显著形态差异。此外,基于采自中国东南部的一系列标本,描述了一新种——东方短腿蟾。至此,短腿蟾属成员增加到7个,其多样性显然被低估了。另外,基于分类便利性、单系性和紧凑性原则,本研究还讨论了角蟾亚科其他单系群的属级分类地位问题。

     

    Abstract: The genus-level recognition of monophyletic short-legged toads (Brachytarsophrys) has been recently implicated in the taxonomic debate of Megophrys sensu lato. In the present study, Brachytarsophrys is reasonably regarded as a distinct genus based on significant morphological differentiations and recent molecular analyses. Furthermore, a comprehensive review of this genus is performed, with two species groups proposed based on morphological differences and phylogenetic relationships. Particularly, Brachytarsophrys platyparietus is removed as a synonym of Brachytarsophrys carinense and considered a valid species due to significant genetic divergence and distinct morphological differences. In addition, a new species, Brachytarsophrys orientalis         sp        .         nov        ., is described based on a series of specimens collected from southeastern China. This work takes the member species of the genus Brachytarsophrys to seven, suggesting that the diversity of Brachytarsophrys is underestimated. In addition, the genus levels of other monophyletic groups within the subfamily Megophryinae are discussed.
