摘要

摘要Panaspis属的落叶皮蛙目前在几内亚湾的海洋岛屿上有两个物种，非洲Panaspis和安诺博南P.annobonensis。在这里，我们描述了第三个物种，Panaspis thomensis sp.nov.，圣多美岛特有种。来自先前研究的数据和使用线粒体16S基因进行的新的系统发育分析表明，该新物种与非洲P.africana在遗传上是不同的，并且是相互单系的。形态学数据（分级和形态计量学）确定了两个岛屿种群之间一致但微妙的表型差异。我们还证实，P.annobonensis代表了一个有效的物种，是物种对P.africana的姐妹 + P.thomensis sp.nov.，基于分子和形态学证据。这一描述将几内亚湾海岛上已知的Panaspis物种数量提高到了三种，这对解释当地特有性产生了影响。ZooBank——Panaspis thomensis：lsid:ZooBank.org：act:A1E69D28-CF4C-4070-BBCC-91E39C21DBA6

Review of the leaf-litter skinks (Scincidae: Panaspis) from the Gulf of Guinea Oceanic Islands, with the description of a new species

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.

期刊介绍： African Journal of Herpetology (AJH) serves as an outlet for original research on the biology of African amphibians and reptiles. AJH is an interdisciplinary journal that publishes original articles and reviews from diverse fields and disciplines, such as conservation, phylogenetics, evolution, systematics, performance, physiology, ecology, behavioural ecology, ethology, and morphology. The Journal publishes two issues a year. There are no page charges .
