This species occurs on the eastern slopes of the Andes in Napo Province, Ecuador, at 2,350-3,155m asl. It has been recorded from nine localities and probably occurs somewhat more widely.
Habitat and Ecology
It inhabits upper montane forests and clearings and is tolerant of some limited habitat degradation. It is found beneath rocks and logs by day and on low vegetation at night. It is presumed to breed by direct development, but the site of egg deposition is not known.
It is a common species within its small known range.
The major threat is habitat destruction and degradation due to deforestation for agricultural development, logging, and human settlement.
Its geographic range overlaps with Parque Nacional Sumaco, and slightly with the Reserva Ecológica Antisana. Improved protection of the montane forest habitat of this species is needed.
