This species can be found in the Amazon Basin in Colombia, Ecuador, Peru, northwestern Bolivia, and Brazil. It occurs up to 800 masl in Ecuador.
Habitat and Ecology
Although this species occurs in primary and secondary tropical rainforest, it most commonly is found around temporary ponds in clearings near forest. This species inhabits a variety of non-forest situations (Duellman, 1978; Rodríguez and Duellman, 1994). Reproduction occurs in temporary bodies of water. Eggs are laid out of water, on leaves while tadpoles develop in the water.
It is uncommon throughout most of its range. Can be common in aquiculture ponds in Ecuador.
There are no major threats.
Conservation units are present within its range. In Ecuador, its geographic range overlaps with Parque Nacional Sumaco Napo-Galeras, Reserva de Producción Faunística Cuyabeno, Reserva Biológica Limoncocha, and Parque Nacional Yasuní.
This species was previously within the genus Hyla but has recently been moved to the resurrected genus Dendropsophus (Faivovich, et al., 2005). Many colour morphs of this species have been recognized taxonomically.
