Based on concordant differences in morphology, male advertisement call, and 16S mtDNA barcode distance, we describe a new species of from southern Amazonia, in the states of Mato Grosso and Pará, Brazil. The new species is most similar to and but differs from these species by its proportionally larger eyes and features of the advertisement call. Additionally, genetic distance between the new species and its congeners is 3.0-10.4% based on a fragment of the 16S rRNA gene, which is greater than the threshold typically characterizing distinct species of anurans. Using an integrative approach (molecular, bioacoustics, and adult morphology), we were able to distinguish the new species from other congeneric species. The new species is known only from the type locality where it is threatened by illegal logging and gold mining as well as hydroelectric dams.
基于形态学、雄性求偶鸣叫以及16S线粒体DNA条形码距离的一致差异，我们描述了一种来自巴西南部亚马逊地区马托格罗索州和帕拉州的新物种。该新物种与[具体物种1]和[具体物种2]最为相似，但在眼睛比例较大以及求偶鸣叫特征方面与这些物种不同。此外，基于16S rRNA基因片段，新物种与其同属物种之间的遗传距离为3.0 - 10.4%，这大于通常表征无尾目不同物种的阈值。通过综合方法（分子、生物声学和成年形态学），我们能够将新物种与其他同属物种区分开来。该新物种仅在模式产地被发现，在那里它受到非法伐木、金矿开采以及水电大坝的威胁。
