This species is known from cloud forest in the municipalities of Pensilvania and Samaná, in the department of Caldas, and from the municipalities of Guatepé and Anorí, in Antioquia department, on the eastern flank of the Cordillera Central, in Colombia. It has been recorded from 1,800-2,000m asl.
Habitat and Ecology
It is restricted to primary forest and breeds by direct development and is not associated with streams. It is very small (at most 23mm long) and is very sensitive to any variation in humidity. It is not tolerant of any habitat disturbance.
It is not a common species.
The major threat to this species is habitat loss caused by agricultural development (including the planting of illegal crops).
Its range does not include any protected areas; given the species' sensitivity to any habitat disturbance, protection of remaining primary forest habitat within the range of the species is essential.
