This Andean species from Colombia and Ecuador occurs on the Amazonian slopes of the Cordillera Oriental from Putumayo Department in southern Colombia south to Morona Province in southern Ecuador. It lives at elevations of 1,950-2,660m asl.
Habitat and Ecology
It is a species of cloud forest. Specimens have been found on stems and branches of bushes near, or over, streams at night. There is no information on its adaptability to secondary habitats. It presumably breeds in streams.
There is very little information, since there are only a few records of this species.
The major threats are likely to be deforestation due to agricultural development, the planting of illegal crops, logging, and human settlement, and pollution resulting from the spraying of illegal crops. The species also lives in montane habitats where catastrophic declines have affected other frogs with stream-dwelling larvae, probably as a result of chytridiomycosis.
In Ecuador, its geographic range overlaps with the Reserva Ecológica Cayambe-Coca, the Reserva Ecológica Antisana, Parque Nacional Llanganates, and Parque Nacional Sangay. It is not known from any protected areas in Colombia. Further research is necessary to determine the current population status of this species in the wild, 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).
