This species occurs in the "Amazonian lowlands of Colombia, Ecuador, Peru, northwestern Bolivia, the Guianas, and Amazonian Brazil." (Frost, 2002). It occurs below elevations of 400m asl. There is one record from 1,500m asl in Colombia.
Habitat and Ecology
It occurs on the forest floor in the tropical rainforest. The eggs are laid on the leaf-litter, and the tadpoles are carried on the back to temporary pools. "Diurnal and terrestrial, this species is usually associated with fallen palm fronds, branches, and small gaps in the forest". (Rodríguez and Duellman, 1994).
It is not common in the Guianas but it is common elsewhere.
Habitat destruction and degradation is a threat to this species.
Its range includes many protected areas. In Ecuador, its geographic range overlaps with Parque Nacional Yasuní.
Haddad and Martins (1994) noted that a similar, apparently unnamed, species occurs in the Amazonian lowlands of Peru, and that the review of Phyllobates pictus by Lescure (1976) is probably based on this species. Silverstone (1976) regarded this species as a pattern class of Phyllobates pictus.
