From the IUCN Red List Species Account:

 

Range Description

This species is endemic to the Cordillera Azul, Huánuco Region, Peru, where it can be found at an altitude of between 1,200 and 1,600 m asl. It has also been introduced to the Tarapoto area of San Martin Region, although very little is known about this biological population

Habitat and Ecology

It inhabits montane tropical rainforest. Eggs are deposited in leaf-litter, and the larvae are carried to streams for their development.

Major Threats

It is generally threatened by habitat clearance for agricultural activities (such as cultivation of tea, and other small scale farming). In the past the habitat area where it occurs had been somewhat protected by the presence of terrorist groups (excepting drug crops used in drug trafficking); more recently, coca eradication campaigns and alternative development programs have diminished the presence of drug crops in the region (CIMA 2012). It is also under threat due to illegal collecting for the pet trade (von May et al. 2008).

Conservation Actions

It is found in Parque Nacional Cordillera Azul. Conservation of other areas where this species occurs is required, as is enforcement on smuggling activities. Further research is needed into the distribution, population status, ecology and threats affecting this species, especially with regards to the impact of illegal trade.
