From the IUCN Red List Species Account:


Range Description

This species occurs in northern Colombia and northwestern Venezuela (where it has been reported from the States of Falcón, Lara, Mérida and Zulia, and is expected from Trujillo). A record from Apure State, east of the Andes in Venezuela, is doubtful and requires confirmation; it is not mapped here. It is a species of low altitudes occuring from sea level up to 500m asl.

Habitat and Ecology

It is a nocturnal, terrestrial species that lives in grasslands and open environments, including semi-arid habitats. They make jelly nests in water and the carnivorous tadpoles develop in temporary pools. It is an opportunistic species, breeding when conditions become suitable.


It is generally an uncommon species. It can be abundant in certain localities, but its distribution appears to be patchy, there are sometimes several kilometres between populations, even in apparently suitable habitat. This species was listed as having experienced population declines by Vial and Saylor (1993), but there is little evidence to support this view.

Population Trend


Major Threats

It might be adversely affected by droughts, and the national and international pet trade might have a local impact. Agriculture and livestock grazing in the eastern part of its range might also affect it.

Conservation Actions

It occurs in the Parque Nacional Morrocoy in Venezuela, and in several protected areas in Colombia.

Red List Status

Least Concern (LC)


Listed as Least Concern in view of its wide distribution, tolerance of a broad range of habitats, presumed large population, and because it is unlikely to be declining fast enough to qualify for listing in a more threatened category.
