This species is known only from the type locality, at Cerro Jaua (04° 49' 55''N; 64° 25' 59''W), in Bolívar State, Venezuela, at 1,600m asl. It might also occur at lower altitudes on the slopes of Cerro Jaua, but this requires confirmation. It is probably a slope-loving species, and is likely to occur more widely.
Habitat and Ecology
This nocturnal species is found on branches of vegetation 0.3-1m above the ground, along streams on the slopes of tepui. Males call from small trees in the margins of the river and on rocks and small trees in the middle of the river. The breeding habits are unknown, although reproduction is likely to take place in streams.
It is common.
The threats to this species are unknown.
It is found within Parque Nacional Jaua-Sarisariñama.

Data Deficient (DD)
Listed as Data Deficient since it has only recently been described, and there is still very little known about its extent of occurrence, area of occupancy, status and ecological requirements.
This species was previously within the genus Hyla but has recently been moved to the resurrected genus Hypsiboas (Faivovich et al. 2005).
