This species is known only from the Nudo de Pasto area on the eastern slopes of the Andes in southern Colombia and northern Ecuador. In Ecuador, it has been recorded only in the extreme north-eastern páramos around Sánta Barbara on the Cordillera Oriental on the border with Colombia. It has been recorded at about 1,950-2,700m asl.
Habitat and Ecology
A cloud forest species, it has also been found in partially cleared forest, where frogs were found at night on branches of trees above a stream. However, its adaptability to disturbed habitats is not well known. It breeds in streams.
It is a rare species.
The major threats are likely to be deforestation due to agricultural development, planting of illegal crops, logging, and human settlement, and pollution resulting from the spraying of illegal crops. All known localities in Ecuador are subject to severe human disturbance. The species lives in montane habitats where catastrophic declines have affected other frogs with stream-dwelling larvae, probably as a result of chytridiomycosis.
It is not known from any protected areas, and there is an urgent need to expand the protected area coverage in the Colombian Andes. Research is needed to determine the current population status of this species and to ascertain whether chytrid poses a threat.
This species was previously within the genus Hyla but has recently been moved to the resurrected genus Hyloscirtus (Faivovich et al. 2005).
