This species is known only from two localities in Napo Province, Ecuador: Volcán Sumaco, and the Cordillera de Guacamayos. It probably occurs a little more widely. Its altitudinal range is 2,040-2,500m asl.
Habitat and Ecology
It lives in very humid, low cloud forest, and breeds in streams. There is no information on its adaptability to secondary habitats.
There is no information on the population status of this species.
The main threat is forest clearance due to agriculture, livestock farming, and wood extraction. It lives in montane habitats where catastrophic declines have affected other frogs with stream-dwelling larvae, probably as a result of chytridiomycosis.
The geographic range of this species overlaps with Parque Nacional Sumaco. Continued and strengthened management of this reserve, and expanded protection of cloud forest elsewhere in the range of this species, are needed. Further survey work is necessary to determine its current population status, and whether chytrid poses a threat.
This species was previously included in the genus Hyla but has recently been moved to the resurrected genus Hyloscirtus (Faivovich et al. 2005).
