This species can be found from the southern Cordillera Central, from Nevado de Huila, Colombia to extreme northern Ecuador, at 2,280 -3,500m asl. The central and northern Cordillera Central records (Antioquia-Tolima departments) and the Cordillera Occidental records (Jericó, Antioquia departments), correspond to a different species, E. permixtus. In Ecuador, it is now known from two localities, El Carmelo and El Chamizo in Carchi Province.
Habitat and Ecology
This species occurs in cloud forest, sub-páramo, and páramo areas. It has been found beneath rocks, logs, or in deep grass. It has also been reported as being associated to streams, bromeliads, leaf litter and vegetation up to 3m high (Mueses-Cisneros, 2005). At night, specimens are active on vegetation (Lynch 1979d). It is presumed to breed by direct development, but the site of egg deposition is not known. It occurs in old-growth and secondary forest.
It was abundant in the 1970s and 1980s throughout its range. Since then, only a few individuals have been found in Ecuador, at El Chamizo, in Carchi Province in 2000.
The major threat is habitat loss caused by logging and agricultural development (livestock and illegal crops).
It occurs in Parque Nacional Natural Puracé and Parque Nacional Natural Nevado de Hulia in Colombia. It is not recorded from any protected areas in Ecuador.
