摘要

摘要:我们描述了两种来自秘鲁东北部Colán山脉的陆生繁殖蛙。我们使用分析法和最大似然法在由75个末端组成的数据集上推断分子系统发育,其中包括代表新物种的三个末端,以及4202bp的串联mtDNA和nuDNA片段。我们的系统发育分析支持将这两个新物种分别放在Lynchius和Oreobates中。从1977年到2006年,Lynchius的新物种出现在两个地方,其特征是背部被圆锥形结节覆盖,背部呈棕色,侧翼和后肢的隐藏表面没有斑点。Oreobates的新物种仅在海拔2608米的一个位置已知,其特征是没有腋窝和腹股沟腺,身体暗棕色隐藏表面有白色或奶油状斑点。

Two new species of terrestrial-breeding frogs (Anura: Brachycephaloidea) from Cordillera de Colán, Peru
ABSTRACT We describe two new species of terrestrial-breeding frogs from the Cordillera de Colán, in northeastern Peru. We used Parsimony and Maximum Likelihood approaches to infer a molecular phylogeny on a dataset composed of 75 terminals, including three terminals representing the new species, and 4202 bp of concatenated mtDNA and nuDNA fragments. Our phylogenetic analyses support the placement of the two new species in Lynchius and Oreobates, respectively. The new species of Lynchius occurs in two localities from 1,977 to 2,006 m a.s.l., and is characterized by having a dorsum covered by conical tubercles and a brown dorsal coloration lacking a pattern of blotches on the hidden surfaces of flanks and hindlimbs. The new species of Oreobates is only known from one location at 2608 m a.s.l. and is characterized by the absence of axillary and inguinal glands, and the presence of white or cream blotches on the dark brown hidden surfaces of the body.
