From the IUCN Red List Species Account:


Range Description

This species is known only from the type locality: "Santa Rita Creek, fourteen miles north of the village of Mesopotamia in the southern part of the Department of Antioquia, Colombia", at 2,472m asl. It is unlikely to range more widely.

Habitat and Ecology

The type locality was forest when the specimens were collected, but the exact habitat requirements of the species are still unknown. It presumably breeds by direct development like other species in the genus.


This species is known from only two specimens collected in 1914. Searches of the type locality since then have not found it, and it is possible that it is now extinct.

Population Trend


Major Threats

At the type locality there has been significant logging in the past, and there is now high human population density in this area with accompanying increased infrastructure development for human settlement. Agriculture, including the planting of illegal crops, is also a threat in the area as well as fumigation of illegal crops.

Conservation Actions

The type locality is not within a protected area. Further survey work is needed to establish whether or not the species still occurs at the type locality or in any location outside the type locality, as the species might already be extinct in view of the scale of habitat destruction in the general vicinity.
