我们根据核基因(Tyr和RAG1)和线粒体基因(12S、tRNA-Val和165)的部分序列，提出了无尾两栖动物Terrarana支系的系统发育假说，检验了Ischnocnema及其种系的单系性。我们对364个终端进行了最大简约、最大似然和贝叶斯推断分析：11个外群终端和353个内群Terrarana终端，包括139个Ischnocnema终端(占35个已命名的Ischnocnema物种中的29个)和Brachycephalidae、Ceuthomantidae、Craugastoridae和Eleutherodactylidae科的214个其他Terrarana终端。不同的最优化标准产生了相似的结果，大部分恢复了目前被接受的科和属。根据这些拓扑结构，Ischnocnema不是一个单系群。我们为三个物种提出了新的组合，将它们重新定位到Pristimantis，并赋予Eleutherodactylus bilineatus Bokermann，1975在全甲亚科中的地位。Ischnocnema的重新安排将其置于最北端的巴西大西洋热带雨林之外，那里的Terrarana动物群由典型的亚马逊属组成。(C)2012 Elsevier Inc.保留所有权利。
We present a phylogenetic hypothesis of the anuran clade Terrarana based on partial sequences of nuclear (Tyr and RAG1) and mitochondrial (12S, tRNA-Val, and 165) genes, testing the monophyly of Ischnocnema and its species series. We performed maximum parsimony, maximum likelihood, and Bayesian inference analyses on 364 terminals: 11 outgroup terminals and 353 ingroup Terrarana terminals, including 139 Ischnocnema terminals (accounting for 29 of the 35 named Ischnocnema species) and 214 other Terrarana terminals within the families Brachycephalidae, Ceuthomantidae, Craugastoridae, and Eleutherodactylidae. Different optimality criteria produced similar results and mostly recovered the currently accepted families and genera. According to these topologies, Ischnocnema is not a monophyletic group. We propose new combinations for three species, relocating them to Pristimantis, and render Eleutherodactylus bilineatus Bokermann, 1975 incertae sedis status within Holoadeninae. The rearrangements in Ischnocnema place it outside the northernmost Brazilian Atlantic rainforest, where the fauna of Terrarana comprises typical Amazonian genera. (C) 2012 Elsevier Inc.
