This species is widely distributed in the lowlands of southwestern Colombia (Departamentos of Valle de Cauca, Cauca, and Nariño) and northwestern Ecuador, below 1,000m asl.
Habitat and Ecology
It is a species of lowland tropical humid forests, also living in secondary growth, but not in open areas. Specimens have been found on low vegetation in the spray zone of a small waterfall. It is not known whether or not the species is restricted to these waterfall habitats. It is presumed to breed by direct development, but the egg deposition site is not known.
It is generally uncommon, but is occasionally locally abundant.
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.
It occurs in some protected areas in Colombia. In Ecuador, its geographic range overlaps with the Reserva Ecológica Cotacachi-Cayapas.
