This species is currently known only from two localities: San Pedro, Cosnipata (Cuzco Department), and San Gaban (Puno Department) in south-eastern Peru. Its altitudinal range is 820-1,480m asl.
Habitat and Ecology
This is a diurnal, riparian species of primary cloud and montane forest, which presumably lays terrestrial eggs, with the larvae then being transported to streams for development.
It is uncommon.
In San Gaban it is mainly affected by agricultural activities (mosty smallholder cultivation of coffee).
A locality recorded for Cuzco is within Parque Nacional Manu.
