This species is known from Amazonian Ecuador (Sucumbios, Orellana and Pastaza Provinces) and adjacent Colombia in the Department of Putumayo. It has been recorded between 330-570m asl. It is likely to occur more widely.
Habitat and Ecology
It is an inhabitant of primary and secondary forest and flooded forest (Duellman, 1978). It is active mostly at night among fallen leaves and low vegetation, it is frequently found in epiphytes. It presumably breeds by direct development like other species in the genus, with egg deposition in the leaf-litter. The ability of the species to adapt to modified habitats is unknown.
In Ecuador, it is an uncommon frog although widely distributed. There is no population information for Colombia.
Habitat loss caused by deforestation, agricultural development, and illegal crops are localized threats but there are no known threats to the species' overall survival at present.
In Colombia it is known from La Payas Nature Reserve. In Ecuador, its geographic range overlaps with Reserva Biológica Limoncocha and Parque Nacional Yasuní. More research into the species' Extent of Occurrence and population status is needed.
