In central Peru this species is known along the Cordillera Oriental in Huancabamba (1,700m asl) and Valle del Perene (1,200m asl), in Pasco Department. In southern Peru it is known from Huanhuachayocc (1,630m asl), Ayacucho Department, and Cosñipata (1,700m asl), Cusco Department. It is likely that it occurs more widely.
Habitat and Ecology
In southern Peru, localities are in cloud forest at the start of the Andes. In central Peru, recorded localities are valleys (vegetation type not known) of the Amazonian drainage. Individuals have been recorded perched on herbaceous vegetation in cloud forest at night. It is not known if the species occurs in modified habitats. Eggs are deposited on leaves, and larvae develop in streams.
Its population status is unknown.
In southern Peru it is threatened by loss and degradation of its habitat for human settlement and smallholder agriculture.
This species occurs in the well-protected Parque Nacional Manu. The potential impacts of localized climate change and possible infection with the chytrid fungus require further investigation.
