This species is known from a few localities at elevations of 1,200-1,780m asl in cloud forest on the Pacific slopes of the Andes in northern Ecuador (Carchi and Esmeraldas Provinces) and adjacent Colombia (Nariño Department). It might occur a little more widely.
Habitat and Ecology
It is nocturnal, and is usually active on vegetation 1-3m above the ground, inside dense and undisturbed cloud forests. It may occur on vegetation along streams. The ability of this species to adapt to modified habitats is unknown. It is presumed to breed by direct development, but the site of egg deposition is not known.
There is little information on the current population status of this species. However, it was observed and photographed in the mid-1990s in La Planada, Colombia.
The major threat is habitat loss caused by agricultural development (including the cultivation of illegal crops). 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 some populations of this species are distributed in La Planada National Reserve, while in Ecuador its geographic range overlaps with the Reserva Ecológica Cotacachi-Cayapas.
