This species is found on the lower Amazonian slopes of the Andes in northern and southern Ecuador (Sucumbios, Pastaza and Zamora Chinchipe Departments), at elevations of 1,100-1,600m asl. It might occur a little more widely.
Habitat and Ecology
It lives in montane rainforest along streams with steep gradients (Lynch and Duellman, 1973). Reproduction is presumed to occur via eggs laid on vegetation, with the tadpoles developing in the water.
This species is noted as being uncommon across most of its range.
Habitat destruction and degradation is a threat to this species, mainly as a result of smallholder farming activities and clear-cutting of forests. Predictions suggest that, in Ecuador, almost half of the habitats suitable for this species have been deforested (Cisneros-Heredia, 2008).
Its distribution range overlaps with Parque Nacional Sumaco Napo-Galeras, Reserva Ecológica Antisana, Parque Nacional Podocarpus and Parque Nacional Llanganates.
