Scientific Name: Elachistocleis pearsei
Species Authority: (Ruthven, 1914)
Synonym(s):
Hypopachus pearsei Ruthven, 1914
Relictivomer pearsei (Ruthven, 1914)
Taxonomic Notes: It is possible that this species is a synonym of Elachistocleis ovalis, and it was treated as such by Kenny (1969). However, here we treat them as separate, pending resolution of this problem.

Assessment Information [top]

Red List Category & Criteria: Least Concern ver 3.1
Year Published: 2004
Date Assessed: 2004-04-30
Annotations:
Needs updating
Assessor(s): John Lynch, Enrique La Marca
Reviewer(s): Global Amphibian Assessment Coordinating Team (Simon Stuart, Janice Chanson, Neil Cox and Bruce Young)
Justification:
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.

Geographic Range [top]

Range Description: This species occurs mainly in the lowlands of northern Colombia, including the Middle Magdalena Valley, and extending eastwards to northwestern Venezuela (probably in southwestern Zulia State). There is an isolated population of the Pacific versant of central Panama. It is a low-altitude species.
Countries occurrence:
Native:
Colombia; Panama; Venezuela, Bolivarian Republic of

Population [top]

Population: There is little information, but it appears to be uncommon.
Current Population Trend: Unknown
Additional data:
Population severely fragmented: No

Habitat and Ecology [top]

Habitat and Ecology: There is little information. It is a terrestrial species of lowland forests, and possibly also savannahs. Its ability to adapt to secondary habitats is not known. It breeds in temporary pools.
Systems: Terrestrial; Freshwater

Threats [top]

Major Threat(s): It is presumably affected by ongoing habitat loss.

Conservation Actions [top]

Conservation Actions: It is likely to occur in some protected areas, but this is not confirmed.
