This species occurs at intermediate altitudes (2,300-2,900m asl) in the valley of the Río Chingual at localities in both Colombia (Nariño and Putumayo Departments) and Ecuador. In Ecuador, it is only known from around Santa Bárbara. It might occur more widely.
Habitat and Ecology
This frog inhabits leafy upper montane cloud forest (Lynch and Duellman 1980), where it is found among leaves and branches low above the ground. In secondary forests this species can extend its activity to the dense regenerating vegetation on the ground of the forest. It is presumed to be a direct developing species, although the egg deposition site is not known.
There is little recent information regarding its population status. It was common in the 1960s at the Ecuadorian locality.
Habitat loss caused by deforestation, agricultural development, and the cultivation of illegal crops is a threat to this species.
There is no natural reserve area inside its distribution area.
