ABSTRACT An integrative taxonomic review of the genus Boaedon in Angola is provided. A molecular phylogeny, based on 99 genetic samples for which the mitochondrial markers 16S rRNA have been sequenced, reveals 23 monophyletic species-level groups in Africa and indicates the presence of nine species in Angola. Based on both phylogenetic and morphological data, we revalidate and designate a neotype for B. angolensis, describe three new species for Angola (e.g. B. bocagei sp. nov., B. branchi sp. nov., and B. fradei sp. nov.), revalidate B. variegatus from its synonymy with B. lineatus and designate a lectotype for this taxon, and identify B. lineatus var. lineolatus as a junior synonym of B. variegatus. The taxonomic status of the recently described B. paralineatus from Central Africa is discussed with respect to the more inclusive B. lineatus group. Moreover, we report on a new country record for Angola, namely B. mentalis, which we elevate here to full species and discuss the taxonomic status of this species in southern Africa. Finally, we provide an identification key and updated distribution maps for all Boaedon species occurring in Angola, including the Cabinda enclave.

安哥拉家蛇的回顾,Boaedon Duméril、Bibron 和 Duméril 属 (1854)(Serpentes:Lamprophiidae),描述了 Boaedon fuliginosus(Boie,1827)物种复合体中的三个新物种

摘要提供了对安哥拉 Boaedon 属的综合分类学评论。分子系统发育基于 99 个已对其线粒体标记 16S rRNA 进行测序的遗传样本,揭示了非洲的 23 个单系物种水平组,并表明安哥拉存在 9 个物种。基于系统发育和形态学数据,我们重新验证并指定了 B. angolensis 的新型,描述了安哥拉的三个新物种(例如 B. bocagei sp. nov.、B. branchi sp. nov. 和 B. fradei sp. nov. .),从 B. lineatus 的同义词重新验证 B. lineatus 并指定该分类群的选型,并确定 B. lineatus var. lineolatus 作为 B. variegatus 的初级同义词。最近描述的来自中非的 B. paralineatus 的分类地位将根据更具包容性的 B. lineatus 组进行讨论。此外,我们报告了安哥拉的新国家记录,即 B. mentalis,我们在这里将其提升为完整物种,并讨论该物种在南部非洲的分类地位。最后,我们提供了安哥拉所有蟒蛇物种的识别密钥和更新的分布图,包括卡宾达飞地。
