Abstract

Xenodermidae is a generally poorly known lineage of caenophidian snakes found in South, East and Southeast Asia. We report molecular phylogenetic analyses for a multilocus data set comprising all five currently recognised genera and including new mitochondrial and nuclear gene sequence data for the recently described Stoliczkia vanhnuailianai. Our phylogenetic results provide very strong support for the non-monophyly of Stoliczkia, as presently constituted, with S. borneensis being more closely related to Xenodermus than to the Northeast Indian S. vanhnuailianai. Based on phylogenetic relationships and morphological distinctiveness, we transfer Stoliczkia borneensis to a new monotypic genus endemic to Borneo, Paraxenodermusgen. nov. We also present new morphological data for P. borneensis.
异种蛇类(鳞片目:蛇类目:异种蛇科)的系统发育关系及一新属的描述
Xenodermidae是在南亚、东亚和东南亚发现的一个鲜为人知的蛇系。我们报告了一个多位点数据集的分子系统发育分析,该数据集包括所有五个目前公认的属,包括最近描述的Stoliczkia vanhnuailianai的新的线粒体和核基因序列数据。我们的系统发育结果为Stoliczkia的非单系性提供了强有力的支持,S. borneensis与Xenodermus的亲缘关系比与东北印度S. vanhnuailianai的亲缘关系更近。基于系统发育关系和形态特征,我们将Stoliczkia borneensis转移到婆罗洲特有的一个新的单型属Paraxenodermusgen。11 .我们也提出了新的形态学资料。
