This species occurs in the state of Bolívar in Venezuela, and in the adjacent portion of western Guyana (Mt Ayanganna and Paramakatoi), from 500-1,850m asl.
Habitat and Ecology
It inhabits tropical rainforests, where it is found on leaves of low herbaceous plants and bushes usually over slow moving streams. Males have been found on exposed bedrock in streams of gallery forests and calling from marginal vegetation at heights up to 3m above the water. The eggs are laid in pools and slow moving streams, where the larvae also develop.
It appears to be a common species.
There are no major threats to the species overall at present, since it occurs in a region where there are minimal impacts to its habitat.
Its range includes several protected areas.
Red List Status
Least Concern (LC)
Listed as Least Concern in view of its wide distribution, presumed large population, and because it is unlikely to be declining fast enough to qualify for listing in a more threatened category.
This species was previously within the genus Hyla but has recently been moved to the resurrected genus Hypsiboas (Faivovich, et al., 2005). This form is a complex of more than one species (some of the western populations appear to be a different taxon).
