This species can be found in the valley of the Río Papallacta on the eastern face of the Andes in Napo Province, Ecuador, and Putumayo Department, Colombia, at elevations of 2,160-2,750m asl. In Ecuador, the species is only known from four localities. It probably occurs more widely.
Habitat and Ecology
This species has been found in partially cleared and old growth cloud forest. It is active at night on top of low herbaceous vegetation. Mueses-Cisneros (2005) reported finding specimens next to the shores of the Rio Putumayo and within the forest, from ground level, on top of herbaceous vegetation, up to 3m high, above shrubs. It is presumed to breed by direct development, but the site of egg deposition is not known.
This species was recorded as common in Guacamayos, La Sofia, Cosanga, and Reventador, Ecuador, in 2003.
General habitat loss due to logging and agricultural development (including the planting of illegal crops) is a major threat.
It occurs in Reserva Ecológica Cayambe-Coca and Reserva Ecológica Antisana in Ecuador.
