The genus Pedioplanis reaches its northernmost limit in western Angola, where it is represented by three species, Pedioplanis benguelensis, P. haackei and P. huntleyi. The taxonomic status of P. benguelensis remains problematic, mainly due to the vague original description and the loss of the original type material. Here we provide a revision of the Angolan representatives of the genus, with the description of a new species, Pedioplanis serodioi sp. nov., from the lowlands of southwestern Angola. Phylogenetic analyses using a combination of mitochondrial (16S and ND2) and nuclear (RAG-1) markers, as well as morphological data, support the recognition of the new species. For purposes of nomenclatural stability, we designate a neotype for P. benguelensis and provide motivation to correct the spelling of the specific epithet to benguelensis. The clarification of the status of P. benguelensis and the description of a new species contribute to a better understanding of the taxonomy and biogeography of the genus Pedioplanis, as well as the general biogeographic context of southwestern Angola, adding to the growing evidence in favor of the recognition of this region as a hotspot of lizard diversity and endemism. An updated key to the genus is also provided.
该属 Pedioplanis 的分布北限达到安哥拉西部，那里有三个物种，即 Pedioplanis benguelensis、P. haackei 和 P. huntleyi。P. benguelensis 的分类地位仍然存在问题，主要是由于原始描述模糊和原始模式标本丢失。在这里，我们对安哥拉代表种进行修订，描述了一个新种，即来自安哥拉西南部低地的 Pedioplanis serodioi sp. nov.。使用线粒体（16S 和 ND2）和核（RAG-1）标记以及形态数据的系统发育分析支持对新种的识别。为了保持命名稳定性，我们指定了 P. benguelensis 的正模，并提出了纠正其种名拼写的理由，拼写应改为 benguelensis。P. benguelensis 地位的澄清和新种的描述有助于更好地理解 Pedioplanis 属的分类学和生物地理学，以及安哥拉西南部的一般生物地理背景，这为承认该地区是蜥蜴多样性和特有性的热点提供了更多证据。还提供了属的更新钥匙。
