This species is known only from the type locality in the Serra do Navio, in the state of Amapá, in Brazil north of the Amazon Delta, and in neighbouring French Guiana. It has been recorded from sea level up to 200m asl.
Habitat and Ecology
It occurs in the understorey vegetation of lowland tropical rainforest. Males call from above water (ponds and small rivulets), and the eggs are laid in the water, where the tadpoles also hatch and develop.
It is an uncommon species.
There are no known threats to this species at present.
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).
