This species is known from two localities close together; one in Parque Nacional Natural Munchique and the other just outside the park, both in Cauca department, on the western slope of the Cordillera Occidental in Colombia, from 1,470-1,600m asl.
Habitat and Ecology
This species is a microhabitat specialist, found on rocks near waterfalls in streams in primary forests. It has not been recorded outside primary forest. It breeds by direct development.
It is not thought to be a rare species.
There are no major threats to the species' habitat at present, as its habitat is relatively well protected. Some other species of Eleutherodactylus that are associated with streams at high elevations have undergone dramatic declines and disappearances, possibly due to chytridiomycosis, so the status of this species should be monitored carefully.
One locality is within Parque Nacional Natural Munchique, and the other is in a private reserve that has well-protected primary forest. The maintenance of these protected areas is essential for the long-term survival of this restricted-range, microhabitat specialist.
Red List Status
Listed as Vulnerable because it is known from fewer than five locations.
