ABSTRACT Leaf-litter skinks of the genus Panaspis are currently represented in the oceanic islands of the Gulf of Guinea by two species, Panaspis africana and P. annobonensis. Here we describe a third species, Panaspis thomensis sp. nov., endemic to São Tomé Island. Data from previous studies and a new phylogenetic analysis using the mitochondrial 16S gene shows that the new species is genetically divergent and reciprocally monophyletic with respect to P. africana. Morphological data (scalation and morphometry) identify consistent, yet subtle, phenotypic differences between the two island populations. We also confirm that P. annobonensis represents a valid species, sister to the species pair P. africana + P. thomensis sp. nov., based on both molecular and morphological evidence. This description raises the number of known Panaspis species in the Gulf of Guinea oceanic islands to three, with consequences for the interpretation of local endemicity.

来自几内亚湾大洋洲群岛的落叶石龙子 (Scincidae: Panaspis) 的回顾，以及一个新物种的描述

摘要 Panaspis 属的落叶石龙子目前在几内亚湾的海洋岛屿中有两个物种，Panaspis Africana 和 P. annobonensis。在这里，我们描述了第三种， Panaspis thomensis sp。11 月，是圣多美岛的特有种。先前研究的数据和使用线粒体 16S 基因的新系统发育分析表明，新物种在遗传上与非洲假单胞菌不同，并且相互单系。形态学数据（缩放和形态测量）确定了两个岛屿种群之间一致但微妙的表型差异。我们还确认 P. annobonensis 代表一个有效的物种，是物种对 P. Africana + P. thomensis sp. 的姐妹。11 月，基于分子和形态学证据。这种描述将几内亚湾海洋岛屿中已知的 Panaspis 物种数量增加到三个，对当地特有性的解释产生了影响。ZooBank-Panaspis thomensis: lsid: zoobank.org:act:A1E69D28-CF4C-4070-BBCC-91E39C21DBA6
