Peru is well known for amphibian diversity and endemism, yet there have been relatively few field studies of glassfrog (Centrolenidae) diversity in this country. Research in Colombia and Ecuador indicates that centrolenid diversity is higher in the northern Andes. However, part of this trend appears to be due to sampling effort. We conducted fieldwork throughout northern Peru, and based on phylogenetic analysis of DNA sequences, combined with bioacoustic and morphological analyses of new and available material we now recognize 33 species from the country (versus 30 species prior to this work). Field surveys led to the discovery of four remarkable species: Centrolene charapita new species is a large, ornamented glassfrog that appears to be sister to Ce. geckoideum; Chimerella corleone new species represents the second-known member of the genus Chimerella; Cochranella guayasamini new species is the second-known member of the genus with humeral spines; and Hyalinobatrachium anachoretus new species occurs in the cloud forest of the east-Andean versant in Peru. In addition to the new species described here, we provide new country records, new localities including range extensions of up to 875 km, information on diagnostic characters and phylogenetic relationships, call and larval descriptions, and observations on natural history for several Peruvian centrolenids. Our results also revealed several taxonomic problems concerning species of the genus Rulyrana, and we conclude that R. croceopodes and R. tangarana are junior synonyms of R. saxiscandens. By implication of our phylogenetic analyses, we recognize the following new combinations: Espadarana audax new combination, Espadarana durrelorum new combination, and Espadarana fernandoi new combination.
秘鲁以其两栖动物的多样性和特有性而闻名，但该国对玻璃蛙（瞻星蛙科）多样性的实地研究相对较少。在哥伦比亚和厄瓜多尔的研究表明，安第斯山脉北部的瞻星蛙科多样性更高。然而，这种趋势部分似乎是由于采样工作。我们在秘鲁北部进行了实地调查，并基于DNA序列的系统发育分析，结合对新的和现有材料的生物声学及形态学分析，我们现在确认该国共有33个物种（而在这项工作之前为30个物种）。实地调查发现了四个引人注目的物种：查拉皮塔瞻星蛙新物种是一种大型、有装饰的玻璃蛙，似乎是Geckoideum瞻星蛙的姐妹物种；科莱昂嵌合瞻星蛙新物种是嵌合瞻星蛙属已知的第二个成员；瓜亚萨米尼科克伦瞻星蛙新物种是该属已知的第二个有肱骨棘的成员；隐居透明瞻星蛙新物种出现在秘鲁东安第斯山坡的云雾森林中。除了这里描述的新物种，我们还提供了新的国家记录、新的地点，包括范围扩展达875公里的记录、关于诊断特征和系统发育关系的信息、叫声和幼体描述，以及对几种秘鲁瞻星蛙科动物自然史的观察。我们的结果还揭示了关于鲁利拉纳瞻星蛙属物种的几个分类学问题，我们得出结论，克罗塞奥波德斯瞻星蛙和坦加拉纳瞻星蛙是萨克西斯坎登斯瞻星蛙的次异名。根据我们的系统发育分析，我们确认了以下新组合：奥达克斯埃斯帕达瞻星蛙新组合、杜雷洛姆埃斯帕达瞻星蛙新组合和费尔南多埃斯帕达瞻星蛙新组合。
