This species occurs in the Amazon Basin from southern Colombia and adjacent Ecuador south through Peru to northern Bolivia, the Guianas and the upper Orinoco Basin in Venezuela and Brazil. It generally occurs below 400m asl but can occur at up to 1,000m asl in Ecuador.
Habitat and Ecology
It inhabits the trees and branches of tropical rainforest. In the rainy season, nocturnal and arboreal adults are most commonly seen perched transversely on stems and small branches above slow moving streams (Rodríguez and Duellman, 1994). The eggs are laid in water, and the tadpoles also develop in water.
It is abundant in much of its range, but it is uncommon in Suriname and Bolivia.
Forest conversion, logging, clear cutting and fire are threats to this species.
Conservation units are present within its range. In Ecuador, its geographic range overlaps with Reserva de Producción Faunística Cuyabeno, Parque Nacional Yasuní, Reserva Biológica Limoncocha, Parque Nacional Sumaco Napo-Galeras and Parque Nacional Podocarpus.
This species was previously within the genus Hyla but has recently been moved to the resurrected genus Hypsiboas (Faivovich, et al., 2005).
