Class Order Family
Amphibia Anura Allophrynidae

Taxonomic Comments: This is a problematic taxon that has been assigned to different families (Allophrynidae, Bufonidae, Centrolenidae, Hylidae, Leptodactylidae).

Global Conservation Status

IUCN Category: This species either has not been evaluated or is considered of Lesser Concern by the IUCN.
IUCN Red List Category Rationale: Listed as Least Concern in view of its wide distribution, presumed large population, and because it is unlikely to be declining fast enough to qualify for listing in a more threatened category.
IUCN Red List Assessor(s): Enrique La Marca, Claudia Azevedo-Ramos
CITES Status: None
General Status Comments: This species was listed as having population declines in Vial and Saylor (1993). Unfortunately, no arguments were given to this point of view, and the locality has not been documented yet for this taxon in Venezuela. The species was also listed as Endangered in Péfaur and Rivero (2000) with no evidence other than citing Vial and Saylor (1993).

It is associated with ponds, creeks and rivers, although it prefers forests that are not too dense. It is mostly terrestrial, and has been found in terrestrial bromeliads and on vegetation 1 to 3m above the ground or water. It is an explosive breeder, and lays its eggs in temporary ponds in the forest. It appears to be restricted to primary forest.
Population Status
It is a common species, but can be difficult to find because of its explosive breeding habits.
Distribution Status in Mexico and Central America

Native Brazil, French Guiana, Guyana, Suriname, Venezuela
