This species is known from the Ecuadorian Amazon Basin in Napo moist forests in the Eastern tropical Altitudinal Zone, and from the department of Putumayo (between Alto Río Caquetá) in Colombia. It occurs between 200-700m asl.
Habitat and Ecology
This species lives in leaf-litter close to streams of primary and secondary Terra Firme forest and seasonal flooded forest. It has also been recorded from ant nests in banana plantations. Eggs are laid in leaf-litter and when hatched the males carry the tadpoles to small temporary or permanent pools on their backs and the tadpoles develop in these pools. It is not known from any anthropogenic habitats.
It is a common species in primary forest but is usually found in lower densities in secondary forest.
Habitat destruction and degradation are localized threats to the species. The natural vegetation of 27.2% of its distribution area (as defined by the GAA polygon) has been cleared by 1996 (based on Sierra, 1999 map).
In Ecuador its distribution range overlaps with Parque Nacional Yasuni, Reserva Biólogica Limoncocha, and Reserva de Produccion Faunistica Cuyabeno. It is not known from any protected areas in Colombia. More research into the species' Extent of Occurrence is desirable.
The species had previously been confused with Ameerega parvula according to the original description.
