Taxonomic Notes: In the Edentulus clade of Ron et al. (2006). Morphometric and call differences allow for discrimination between this species and the closely related  Engystomops (was Physalaemus)freibergi (Funk et al. 2008).

Assessment Information [top]

Red List Category & Criteria: Least Concern ver 3.1
Year Published: 2010
Date Assessed: 2008-12-08
Assessor(s): Ariadne Angulo
Reviewer(s): Ariadne Angulo and Simon Stuart
Listed as Least Concern in view of its wide distribution, tolerance of a degree of habitat modification, presumed large population, and because it is unlikely to be declining to qualify for listing in a more threatened category.

Geographic Range [top]

Range Description:This species is known to occur in Amazonian Ecuador, northeastern Peru, and Amazonian Colombia. Further research is needed to determine whether the species that occurs in French Guiana is P. petersi, P. freibergi, or an undescribed species (Funk et al., 2008). We temporarily include this population in P. petersi's account until its taxonomic status can be clarified. It occurs between 89 and 1200 masl in Ecuador.

Habitat and Ecology [top]

Habitat and Ecology:This diurnal and nocturnal species has been found in primary and secondary forest, and forest edge (Duellman, 1978). It is terrestrial, and is often found in leaf-litter. Breeding takes place in temporary waterbodies and slow-moving streams during the wet season. Its eggs on foam nest next to pools and tadpoles are found in the water.
Systems:Terrestrial; Freshwater

Threats [top]

Major Threat(s): Local populations are probably impacted by severe habitat loss, such as clear-cutting, and agricultural expansion. However, overall, this species is not significantly threatened.

Conservation Actions [top]

Conservation Actions: It occurs in many protected areas.
