Amphibians are the most vulnerable vertebrates to biodiversity loss mediated by habitat destruction, climate change and diseases. Informed conservation management requires improving the taxonomy of anurans to assess reliably the species' geographic range. The genus that is geographically refined to Argentina, Bolivia, Brazil, Uruguay and Paraguay includes currently 12 nominal species with many populations of uncertain taxonomic assignment and subsequently unclear geographic ranges. In this study, we applied integrative taxonomic methods combining molecular (mitochondrial 16S gene), allozyme, morphological and bioacoustic data to delimit species of the genus sampled from throughout Argentina where most species occur. The combined evidence demonstrates one case of cryptic diversity and another of overestimation of species richness. The populations referred to as comprise at least three species. In contrast, and represent junior synonyms of the phenotypically plastic species . We conclude that each of the four species occurring in Argentina inhabits medium to large areas. The Red List classification is currently "Least Concern". We also propose a phylogenetic hypothesis for the genus and associated genera and (Odontophrynidae).
两栖动物是最易受栖息地破坏、气候变化和疾病介导的生物多样性丧失影响的脊椎动物。明智的保护管理需要改进无尾两栖类的分类学，以便可靠地评估物种的地理分布范围。该属在地理上分布于阿根廷、玻利维亚、巴西、乌拉圭和巴拉圭，目前包括12个命名物种，许多种群的分类归属不确定，地理分布范围也不明确。在本研究中，我们应用综合分类学方法，结合分子（线粒体16S基因）、等位酶、形态和生物声学数据，对从阿根廷各地采集的该属物种进行界定，阿根廷是该属大多数物种的分布地。综合证据表明存在一个隐存多样性案例和另一个物种丰富度高估案例。被称为……的种群至少包含三个物种。相比之下，……和……是表型可塑性物种……的次异名。我们得出结论，在阿根廷出现的四个物种各自栖息于中等到大面积区域。目前红色名录分类为“无危”。我们还提出了该属以及相关属……和……（齿蟾科）的系统发育假说。
