This species occurs in the Anangu/Garzacocha region of the Río Napo in eastern Ecuador and nearby Amazonian Colombia and Peru. It is also known from Manaus and the Juruá river, Amazonas state, Brazil. It is found below 300m asl.
Habitat and Ecology
The type locality is a tropical wet forest and is believed to be mostly undisturbed except for scattered patches (Vigle and Goberdhan-Vigle, 1990). This species calls from water hyacinths and bushes in ponds and along slow-moving streams in, or at the edge of tropical rainforest (Rodríguez and Duellman, 1994). The eggs are laid in water, and the tadpoles develop there also.
It can be common in appropriate habitats; these are ponds with floating vegetation.
Habitat destruction, degradation, and water pollution are threats to this species. The range in Brazil is well preserved.
The range of this species includes several protected areas. In Ecuador, its geographic range overlaps with Reserva de Producción Faunística Cuyabeno and Reserva Biológica Limoncocha.
This species was previously within the genus Hyla but has recently been moved to the resurrected genus Dendropsophus (Faivovich, et al., 2005).
