This species is known from the upper Amazon Basin in Ecuador within a latitudinal range encompassed by the Río Napo to the north and the Río Curary to the south. Also known from two localities near Iquitos, Junction of Río Yanamono and Río Amazonas, Quebrada Grande, junction of Río Sucusari and Río Napo Departamento Loreto, in northeastern Peru. It has been recorded from Leticia in Colombia. All localities are from 100-250m in elevation. Further work is likely needed to understand if this species occurs more widely.
Habitat and Ecology
This species can be found in tropical primary moist forest including terra firme forest and seasonally flooded forest. It has been recorded from open areas (Ron and Pramuk, 1999) but this requires further investigation. Breeding takes place in temporary pools. It is not present in degraded areas.
This species is reasonably abundant.
There are no major threats, it is a widespread species with large areas of suitable habitat remaining. There is some localized habitat loss to general human activities such as agriculture (crops, livestock etc.).
In Peru, this species might occur in Allpahuayo Mishana Reserved Zone and Pacaya Samiria National Reserve. In Ecuador, its geographic range overlaps with Parque Nacional Yasuní.
