This species is known only from the Colombian and Ecuadorian Andes. In Colombia it occurs patchily in the Cordillera Occidental and the Cordillera Central, and on the eastern slope of the Nudo del Pasto (in the departments of Risaralda, Valle del Cauca, Quindio and Tolima). In northern Ecuador it is known only from a small area in Carchi and Imbabura Provinces. Its altitudinal range is 1,950-3,100m asl. It probably occurs a little more widely than current records suggest.
Habitat and Ecology
It lives on vegetation (including in bromeliads and on branches) in primary and secondary forests next to water sources (usually streams). It has been found in a small, wooded ravine in otherwise cleared pastureland, and breeds in slow-moving streams.
Although patchily distributed, it is common where found.
The major threats are deforestation for agricultural development, cultivation of illegal crops, logging, and human settlement, and pollution resulting from the spraying of illegal crops.
In Ecuador, its geographic range overlaps with the Reserva Ecológica Cotacachi-Cayapas. It occurs in several protected areas in Colombia.
This species was previously within the genus Hyla but has recently been moved to the resurrected genus Hyloscirtus (Faivovich et al. 2005).
