This species is known only from 1,735-1,840m asl on the western slopes of the Cordillera de Huancabamba (Piura Department), Peru.
Habitat and Ecology
It can be found in humid montane forest, where males have been observed calling from herbaceous vegetation 0.3-1.0m above the ground. Individuals have also been collected from low vegetation in disturbed habitat where there were a few large trees present. This species is presumed to breed by direct development.
It is abundant where it occurs.
The threats to it are unclear, although at the type locality there is some destruction and loss of habitat to due to livestock grazing and subsistence collection of wood.
It is not known from any protected areas. There is a need to maintain the remaining habitat at the type locality. Further research is needed for this largely unknown species.
