叉舌蛙是两栖动物无尾目的成员，属于双舌蛙科，是无尾蛙中最多样化的群体之一；然而，它们的分类和系统发育仍然存在争议。本研究利用代表9个双舌属和23个新蛙属的16个双舌属线粒体基因组，采用不同的划分极大似然和划分贝叶斯推理方法，在核苷酸和氨基酸水平上重建了双舌科的系统发育关系。采样的叉舌蛙形成了一个得到强有力支持的单系群，是另一个得到良好支持的Glade的姐妹分类群，该Glade包括Ranidae， Rhacophoridae和Mantellidae的代表。结果表明，双盲蝽亚科与Occidozyginae具有较强的同源性，双盲蝽亚科中存在两个主要分支。Limnonectes属和Paini部落之间的姐妹族关系得到了支持。此外，Fejervarya与Euphlyctis + Hoplobatrachus、Quasipaa与Yerana、Feirana与Nanorana之间存在姐妹类群关系。分化时间的估计揭示了上白垩世晚期至始新世早期双辉石科的分化，以及始新世早期至中新世中期双辉石属的分化。(C) 2017 Elsevier Ltd.版权所有。
The fork-tongued frogs, members of the amphibian Order Anura, belong to the family Dicroglossidae and are one of the most diverse groups of Anuran frogs; however, their taxonomy and phylogeny remain controversial. In the present study, sixteen dicroglossine mitochondrial genomes representing nine dicroglossine genera and 23 other neobatrachian taxa, were used to reconstruct the phylogenetic relationships of the family Dicroglossidae using different partitioned maximum likelihood and partitioned Bayesian inference methods at both the nucleotide and amino acid levels. The sampled fork-tongued frogs form a strongly supported monophyletic group that is the sister taxon to another well-supported Glade that includes representatives of the families Ranidae, Rhacophoridae, and Mantellidae. The monophyly of the subfamily Occidozyginae and Dicroglossinae was revealed with strong supports, and two major clades were supported within Dicroglossinae. The sister-group relationship between the genera Limnonectes and the tribe Paini was supported. In addition, a sister-group relationships between Fejervarya and Euphlyctis + Hoplobatrachus, between Quasipaa and Yerana, and between Feirana and Nanorana are well supported. Estimates of divergence times revealed the divergence of Dicroglossidae during the Late Upper Cretaceous to the Early Eocene, and diversification of the major dicroglossine genera from the Early Eocene to the Middle Miocene.
