This species occurs along the eastern edge of the Andes from southern Colombia (Departments of Nariño and Putumayo) southward to Napo Province in Ecuador. It occurs at 1,900-3,400m asl.
Habitat and Ecology
It is a species of upper humid montane forest, sub-páramo bush land, and páramo grassland. It is associated with open areas, especially at very highest altitudes. However, in the forest zone, it is generally associated with primary, undisturbed forest, where it can be found in bromeliads up to 3m above the ground. It is generally found under rocks or logs on muddy ground during the day. At night it is very active on the ground and on low perches in grass or small bushes. It is presumed to breed by direct development, but the egg deposition site is not known.
It is a very common species.
The major threats are likely to be deforestation for agricultural development, plantations, illegal crops, logging, and human settlement, and pollution resulting from the spraying of illegal crops.
It is not known from any protected areas in Colombia. In Ecuador, its geographic range overlaps with the Reserva Ecológica Antisana, Parque Nacional Sumaco Napo-Galeras, Parque Nacional Cotopaxi, Area Nacional de Recreación El Boliche, and Reserva Ecológica Cayamba-Coca.
