Data from: Molecular phylogeny and biogeography of Malagasy frogs of the genus Gephyromantis

The genus Gephyromantis is a clade within the Malagasy–Comoroan family Mantellidae composed of rainforest frogs that live and breed to varying degrees independently from water. Based on DNA sequences of five mitochondrial and five nuclear genes we inferred the phylogeny of these frogs with full taxon coverage at the species level. Our preferred consensus tree from a partitioned Bayesian analysis of 5843 base pairs of 51 nominal and candidate species supports various major clades within the genus although the basal relationships among these remain unresolved. The data provide strong evidence for the monophyly of the subgenera Gephyromantis (after exclusion of Gephyromantis klemmeri), Laurentomantis, Vatomantis, and Phylacomantis. Species assigned to the subgenus Duboimantis belong to two strongly supported clades of uncertain relationships. G. klemmeri, previously in the subgenus Gephyromantis, was placed with high support sister to the Laurentomantis clade, and the Laurentomantis + G. klemmeri clade was sister to Vatomantis. A reconstruction of ancestral distribution areas indicates a diversification of several subgenera in the northern biogeographic regions of Madagascar and the dispersal out of northern Madagascar for several clades.

糙皮蛙属（Gephyromantis）是马达加斯加-科摩罗曼蛙科（Mantellidae）下的一个演化支，包含各类在不同程度上独立于水体生活和繁殖的雨林蛙类。本研究基于5个线粒体基因与5个核基因的DNA序列，对该属蛙类开展了物种级全分类群覆盖的系统发育推断。通过对51个名义物种与候选物种的5843个碱基对序列进行分区贝叶斯分析，我们得到了最优共识树：该树支持该属内存在多个主要演化支，但这些演化支之间的基部系统发育关系仍未解析。本研究数据为四个亚属——排除克氏糙皮蛙（Gephyromantis klemmeri）后的糙皮蛙亚属（Gephyromantis）、劳伦蛙亚属（Laurentomantis）、瓦托蛙亚属（Vatomantis）以及菲拉科蛙亚属（Phylacomantis）的单系性提供了强有力的支持证据。归属于杜博蛙亚属（Duboimantis）的物种被划分为两个得到强力支持的演化支，但二者之间的亲缘关系尚不明确。此前被归入糙皮蛙亚属的克氏糙皮蛙（Gephyromantis klemmeri）被置于与劳伦蛙亚属演化支形成高支持率姐妹群的位置，且劳伦蛙亚属与克氏糙皮蛙构成的演化支又与瓦托蛙亚属形成姐妹群。祖先分布区重建结果显示，该属多个亚属的物种多样化过程发生在马达加斯加北部生物地理区，同时多个演化支曾从马达加斯加北部向外扩散。
