This species is known from the region of La Escalera and Cerro Roraima, in Bolívar state, Venezuela to western Guyana (Mount Roraima and Mount Ayanganna). It has been recorded from 600-1,400m asl.
Habitat and Ecology
It has been seen calling from boulders in, and leaves, branches, and a log above a cascading stream. It is also found in open areas with fringe vegetation and in waters that are very stagnant. Some specimens have been found on trees up to 3 metres above the water in gallery forest. The eggs are usually deposited on vegetation overhanging the streams, and when hatched the tadpoles drop in to the water below where they develop further.
It is a locally common species.
Fire is a localized threat, but this species occurs in a region of limited human impact so there are no major threats overall at present.
Some populations are protected within Canaima National Park.
This species was previously within the genus Hyla but has recently been moved to the resurrected genus Hypsiboas (Faivovich, et al., 2005).
