This species is known only from the type locality: La Empalada, in the municipality of Mistrató, in the department of Risaralda, Colombia, from 1,760-1,790m asl. There has been quite extensive sampling in the neighbouring regions suggesting that it is most likely confined to this area.
Habitat and Ecology
It is usually found on low vegetation and in leaf-litter, inside primary cloud forest, and has not been recorded outside forest habitat. It breeds by direct development.
It is a rare species.
The major threat is habitat loss caused by agricultural development, particularly the cultivation of illegal crops.
The type locality is near Parque Nacional Natural Tatama, but it has not been recorded from inside the park. Protection of the species' habitat is essential for the long-term survival of this restricted range, primary forest species.
This is the sister species of Pristimantis bellona according to Lynch and Ruíz-Carranza (1996b).
