We propose to erect a new genus of terrestrial-breeding frogs of the Terrarana clade to accommodate three species from the Province La Convención, Department of Cusco, Peru previously assigned to Bryophryne: B. flammiventris, B. gymnotis, and B. mancoinca. We examined types and specimens of most species, reviewed morphological and bioacoustic characteristics, and performed molecular analyses on the largest phylogeny of Bryophryne species to date. We performed phylogenetic analysis of a dataset of concatenated sequences from fragments of the 16S rRNA and 12S rRNA genes, the protein-coding gene cytochrome c oxidase subunit I (COI), the nuclear protein-coding gene recombination-activating protein 1 (RAG1), and the tyrosinase precursor (Tyr). The three species are immediately distinguishable from all other species of Bryophryne by the presence of a tympanic membrane and annulus, and by males having median subgular vocal sacs and emitting advertisement calls. Our molecular phylogeny confirms that the three species belong to a new, distinct clade, which we name Qosqophryne, and that they are reciprocally monophyletic with species of Microkayla. These two genera (Qosqophryne and Microkayla) are more closely related to species of Noblella and Psychrophrynella than to species of Bryophryne. Although there are no known morphological synapomorphies for either Microkayla or Qosqophryne, the high endemism of their species, and the disjoint geographic distribution of the two genera, with a gap region of ~310 km by airline where both genera are absent, provide further support for Qosqophryne having long diverged from Microkayla. The exploration of high elevation moss and leaf litter habitats in the tropical Andes will contribute to increase knowledge of the diversity and phylogenetic relationships within Terrarana.

来自秘鲁南部的陆地繁殖青蛙的新属（Holoadeninae，Strabomantidae，Terrarana）

我们建议建立一个新的陆地繁殖青蛙属，以容纳秘鲁库斯科省LaConvención省的三个物种，这些物种以前被分配给Bryophryne：B。flammiventris，B.gymnotis和B.mancoinca。我们研究的类型和种类最多，审查形态和bioacoustic特征的标本，并在最大系统发育进行分子分析Bryophryne迄今为止的物种。我们对16S rRNA和12S rRNA基因片段，蛋白编码基因细胞色素C氧化酶亚基I（COI），核蛋白编码基因重组激活蛋白1（RAG1）的串联序列的数据集进行了系统发育分析。和酪氨酸酶前体（Tyr）。通过存在鼓膜和瓣环，以及雄性具有中齿下声囊并发出广告声，这三个物种可立即与所有其他的Bryophryne物种区分开。我们的分子系统发育学证实，这三个物种属于新的独特进化枝，我们命名为Qosqophryne，并且它们与Microkayla菌种互为亲缘。这两个属（Qosqophryne和Microkayla）更密切相关的物种Noblella和Psychrophrynella比种Bryophryne。尽管Microkayla或Qosqophryne都没有已知的形态同形异型，但它们的物种的特有度很高，并且两个属的地理分布不相交，航空公司在两个属均不存在的情况下有约310 km的缺口区域，这为它们提供了进一步的支持。Qosqophryne长期与Microkayla背道而驰。在热带安第斯山脉中探索高海拔的苔藓和凋落物栖息地将有助于增加对Terrarana内多样性和系统发育关系的了解。
