Assessor(s): Abraham Mijares, Enrique La Marca, Mark Wilkinson
Reviewer(s): Global Amphibian Assessment Coordinating Team (Simon Stuart, Janice Chanson, Neil Cox and Bruce Young)
Listed as Least Concern since, although its currently known Extent of Occurrence is probably less than 20,000 km2, it occurs in an area of extensive, suitable habitat which appears not to be under serious threat, it has a presumed large population, and it is unlikely to be declining fast enough to qualify for listing in a more threatened category.
