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.

非洲档案蛇 Gonionotophis Boulenger（有鳞目：Lamprophiidae）的系统发育和属级修订

摘要 撒哈拉以南非洲档案蛇属 Gonionotophis 目前由 15 种组成。然而，该属的概念已被组成分类群之间的形态和遗传差异所混淆。由于缺乏 DNA 样本，分类评估迄今为止是不切实际的。因此，我们对代表 10 种拟角线虫的 45 个样本的两个线粒体和一个核标记（16S、cyt b 和 c-mos）进行了测序，以使用贝叶斯和似然方法构建分子系统发育。回收了四个不同且支持良好的进化枝，包括：（1）grantii + brussauxi；(2) poensis + stenphthalmus; (3) nyassae；(4) capensis、chanleri、crossi、guirali 和 savorgnani。基于这些结果和形态学数据，Gonionotophis 属仅限于第一进化枝，Mehelya 为第二个进化枝中的物种而复活，并为其余两个进化枝描述了新属。ZooBank—urn:lsid:zoobank.org:pub:A82CFAD6-E2E0-439E-90BB-9224E225426B
