This species can be found in cloud forest at 1,410-2,750m asl on the eastern face of the Andes, and on the eastern slope of the Cordillera Central in the departments of Caquetá, Huila, and Putumayo (Colombia), and Sucumbios, Napo, and Pastaza provinces (Ecuador). It probably occurs more widely, in particular in areas between known populations.
Habitat and Ecology
This species can be found in montane cloud forest. It has been found in old-growth forest and in adjacent altered forest. It is nocturnal and occurs inside bromeliads from ground level up to 2m high, and also on herbaceous and shrubby vegetation up to 1.5m high. It is presumed to breed by direct development, but the site of egg deposition is not known.
Historically, this species has been uncommon where collected.
Habitat loss caused by logging and agricultural development (livestock and illegal crops) is a threat.
In Colombia, this species occurs in the San Augustin Archaeological Park and probably also occurs in Parque Nacional Natural Alto Fragua. In Ecuador, it occurs in Parque Nacional Sumaco-Napo Galeras, Parque Nacional Llanganates, Reserva Ecológica Cayambe-Coca and Reserva Ecológica Antisana.
