Abstract

We describe a new species of the South American frog genus Adenomera, based on external morphology, color patterns, advertisement call, and mtDNA sequences. The new species was collected from the Japurá River basin in northwestern Brazilian Amazonia and is distinguished from all congeners by the combination of large snout–vent length (SVL), toe tips unexpanded, presence of antebrachial tubercle on underside of forearm, and by a multi-note advertisement call composed of non-pulsed notes. This new species is part of the A. lutzi clade together with a candidate new species known as Adenomera sp. P and A. lutzi. The three species have the largest SVL in the genus. The presence of toe tips fully expanded and a single-note advertisement call distinguish A. lutzi from the new species. Acoustic and morphological data are still required to assess the taxonomic identity of Adenomera sp. P. Our new species of Adenomera is the third anuran species described from the Solimões-Japurá interfluve. This flags this poorly known region of lowland forests as an important area of species richness in northwestern Amazonia.

标题巴西西北部亚马逊河流域蛙属一新种(细趾蛙科)

我们根据外部形态、颜色模式、广告叫声和mtDNA序列描述了南美洲蛙属腺瘤蛙的一个新种。该新种采自巴西亚马孙河西北部的japur河流域，其与所有同属物种的区别在于其大鼻口长度(SVL)、脚趾尖未扩张、前臂下侧存在前臂结节以及由非脉冲音符组成的多音符广告叫声。这个新种是a . lutzi分支的一部分，另外一个候选新种是Adenomera sp. P和a . lutzi。这三个种在属中具有最大的SVL。趾尖完全扩张的存在和单音符广告叫声将a . lutzi与新种区分开来。尚需要声学和形态学资料来评估其分类特性。我们的新种腺瘤属是Solimões-Japurá间流中描述的第三个无尾动物种。这标志着这个鲜为人知的低地森林地区是亚马逊西北部物种丰富的重要地区。

期刊介绍： Founded in 1913, Copeia is a highly respected international journal dedicated to the publication of high quality, original research papers on the behavior, conservation, ecology, genetics, morphology, evolution, physiology, systematics and taxonomy of extant and extinct fishes, amphibians, and reptiles. Copeia is published electronically and is available through BioOne. Articles are published online first, and print issues appear four times per year. In addition to research articles, Copeia publishes invited review papers, book reviews, and compiles virtual issues on topics of interest drawn from papers previously published in the journal.
