Abstract

ABSTRACT The sub-Saharan African file snake genus Gonionotophis is currently comprised of 15 species. However, the concept of this genus has been confounded by morphological and genetic differences between the constituent taxa. Due to the dearth of DNA samples, a taxonomic assessment has been impractical to date. We therefore sequenced two mitochondrial and one nuclear marker (16S, cyt b, and c-mos) from 45 samples representing ten species of Gonionotophis to construct a molecular phylogeny using Bayesian and likelihood approaches. Four divergent and well-supported clades were recovered, including: (1) grantii + brussauxi; (2) poensis + stenophthalmus; (3) nyassae; and (4) capensis, chanleri, crossi, guirali and savorgnani. Based on these results and morphological data, the genus Gonionotophis is restricted to the first clade, Mehelya is resurrected for the species in the second clade, and new genera are described for the remaining two clades.

非洲蛇属Gonionotophis Boulenger的系统发育及属级修正(鳞目:蛇科)

撒哈拉以南非洲的蛇属Gonionotophis目前由15种组成。然而，该属的概念因其组成分类群之间的形态和遗传差异而混淆。由于缺乏DNA样本，分类评估迄今为止是不切实际的。因此，我们从代表10种Gonionotophis的45个样本中测序了两个线粒体和一个核标记(16S, cyt b和c-mos)，并使用贝叶斯和似然方法构建了分子系统发育。发现了4个分散且支持良好的分支，包括:(1)grantii + brussauxi;(2)斜眼+窄眼;(3) nyassae;(4) capensis、chanleri、crossi、guilali和savorgnani。根据这些结果和形态学资料，Gonionotophis属被限定在第一个分支中，Mehelya属在第二个分支中复活，其余两个分支中描述了新属。ZooBank-urn: lsid zoobank.org:酒吧:a82cfad6 e2e0 - 439 e - 90 - bb - 9224 e225426b
