This species occurs on the Amazonian slopes of the Andes in southern Colombia (in Caquetá and Putumayo Departments) and Ecuador (south to Morona Province). It ranges from 2,000-2,600m asl.
Habitat and Ecology
It lives in upper humid montane forest, and it also survives in pastureland and other altered habitats. However, although it is adaptable, it probably cannot tolerate extremely severe habitat clearance, leading to a very open landscape. It is associated with creeks and breeds in streams. Individuals have been found on vegetation along small creeks within forests; tadpoles have been collected in bodies of water with limited movement (Mueses-Cisneros, 2005).
It is a common species.
The major threats are habitat loss from agricultural development, planting of illegal crops, logging, and human settlement, and pollution resulting from the spraying of illegal crops. The species has a narrow altitudinal range, and lives in habitats where catastrophic extinctions have occurred in other frog species with stream-dwelling tadpoles, perhaps due to chytridiomycosis. Mueses-Cisneros (2005) reports that all tadpoles examined in his study lack keratin in their mouthparts; however, he suggests that this is not necessarily related to chytrid infection.
It occurs in several protected areas in Ecuador, including Parque Nacional Llanganates and Parque Nacional Sangay, but is apparently not recorded from any in Colombia. There is a need for close population monitoring of this species, given the potential threat of chytridiomycosis.
This species was previously included in the genus Hyla but has recently been moved to the resurrected genus Hyloscirtus (Faivovich et al. 2005).
