Gephyromantis 属是马达加斯加-科摩罗 Mantellidae 科的一个分支，由雨林蛙组成，它们在不同程度上独立于水生活和繁殖。根据五个线粒体和五个核基因的 DNA 序列，我们推断出这些青蛙的系统发育，在物种水平上具有完整的分类单元覆盖。我们通过对 51 个名义物种和候选物种的 5843 个碱基对进行分区贝叶斯分析得出的首选一致树支持该属内的各种主要进化枝，尽管这些进化枝之间的基本关系仍未解决。这些数据为 Gephyromantis 亚属（排除 Gephyromantis klemmeri 后）、Laurentomantis、Vatomantis 和 Phylacomantis 亚属的单系性提供了强有力的证据。属于 Duboimantis 亚属的物种属于两个相互关系不确定的、得到有力支持的进化枝。 G. klemmeri 以前属于 Gephyromantis 亚属，被列为 Laurentomantis 分支的高支持姐妹，而 Laurentomantis + G. klemmeri 分支是 Vatomantis 的姐妹。祖先分布区的重建表明马达加斯加北部生物地理区域的几个亚属的多样化以及几个进化枝从马达加斯加北部的扩散。 (C) 2011 Elsevier Inc. 保留所有权利。
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.
