Abstract

We describe two new species of Phrynopus from a cloud forest of the Cordillera Yanachaga, Yanachaga-Chemillén National Park in Peru and describe and document the first clutch and case of parental care for a species of Phrynopus. One of the new species of Phrynopus is described based on two females (SVL 19.1-21.0 mm) which were found in leaf litter and moss layer in a cloud forest at 2900 m elevation. This new species is most similar to Phrynopus bracki. The second new species of Phrynopus was found in the transitional formation between cloud forest and wet puna at 3000 m elevation. Its description is based on a single female (SVL 20.7 mm) that was observed guarding nine eggs under moss. This new species is most similar to Phrynopus nicoleae. The eggs had a diameter of 5.7-5.8 mm (n = 3) and froglets when hatched a SVL of 6.2-6.5 mm (n = 3). Sympatric anurans include Gastrotheca sp., Pristimantis aniptopalmatus, Pristimantis bromeliaceus, Pristimantis sp., and Rhinella yanachaga.

摘要

我们描述了来自秘鲁亚纳查加-切米连国家公园亚纳查加山脉云雾森林中的两种新的褶蛙属物种,并描述和记录了褶蛙属一个物种的首例一窝卵及亲代抚育情况。其中一种新的褶蛙属物种是根据在海拔2900米的云雾森林落叶层和苔藓层中发现的两只雌性个体(体长19.1 - 21.0毫米)描述的。这个新物种与布氏褶蛙最为相似。第二种新的褶蛙属物种是在海拔3000米的云雾森林和潮湿普纳草原的过渡地带发现的。其描述基于一只观察到在苔藓下守护9枚卵的雌性个体(体长20.7毫米)。这个新物种与尼氏褶蛙最为相似。卵的直径为5.7 - 5.8毫米(n = 3),孵化出的幼蛙体长为6.2 - 6.5毫米(n = 3)。同域分布的无尾目动物包括胃囊蛙属物种、无指掌蛙、凤梨蛙、未鉴定的棱皮蛙属物种和亚纳查加蟾蜍。
