From the IUCN Red List Species Account:


Range Description

This species is only known from Pilaló at 2,320m in Cotopaxi Provice, and nearby areas in Ecuador.

Habitat and Ecology

It has been found only in disturbed cloud forest, where adults have been found by day. There is no information on its ability to survive in heavily degraded habitats. Breeding takes place in streams.


Recent efforts to locate the species at the type locality were unsuccessful, but more surveys are needed before it can be concluded whether or not this species has declined in suitable habitats.

Population Trend


Major Threats

At the type locality, patches of forest have been cleared for agriculture and livestock farming, possibly posing a serious threat to the survival of the species. The species lives in habitats where catastrophic extinctions have affected other frogs with stream-dwelling tadpoles, probably as a result of chytridiomycosis.

Conservation Actions

This species is not known from any protected areas, and its remaining intact habitat is in urgent need of protection. Survey work is urgently required to determine the current population status of the species.

Taxonomic Notes

This species was previously included in the genus Hyla but has recently been moved to the resurrected genus Hyloscirtus (Faivovich et al. 2005).
