This species occurs from San Jose del Palmar on the Río San Juan, Department of Choco, on the western flank of the Cordillera Occidental in Colombia, south to northwestern Ecuador. It occurs from near sea level to 1,900m asl, though it is generally found below 1,000m asl.
Habitat and Ecology
It lives in lowland and submontane rainforest. It has been found in both primary and secondary forest, not in open areas. It often perches on broad leaves or on branches along streams at night. It is presumed to breed by direct development, but the egg deposition site is not known.
It is an uncommon species, but it is occasionally locally common.
The major threats are likely to be deforestation for agricultural development, plantations, illegal crops, logging, and human settlement, and pollution resulting from the spraying of illegal crops. It should be noted that some other species of Eleutherodactylus that are associated with streams have undergone dramatic declines and disappearances, possibly due to chytridiomycosis, so the status of this species should be monitored carefully.
In Colombia, the species is marginally present in La Planada private nature reserve, and in the lower parts of the following National Natural Parks: Cerro Munchique; Los Farallones de Cali; and Los Paraguas. In Ecuador, its geographic range overlaps with the Reserva Ecológica Cotacachi-Cayapas.
