Assessment Information [top]

Red List Category & Criteria: Critically Endangered (Possibly Extinct) A2a; B2ab(v) ver 3.1
Year Published: 2010
Date Assessed: 2006-02-28
Needs updating
Assessor(s): Enrique La Marca, Juan Elías García-Pérez
Reviewer(s): Global Amphibian Assessment Coordinating Team (Simon Stuart, Janice Chanson, Neil Cox and Bruce Young)
Listed as Critically Endangered because of a drastic population decline, estimated to be more than 80% over the last ten years, inferred from the apparent disappearance of most of the population; and because its Area of Occupancy is less than 10 km2, all individuals are in a single location, and there is continuing decline in the number of mature individuals.
Date last seen: 1991

Population [top]

Population:It is a very rare species that appears to have declined. Several attempts to find it in recent years have failed, and it is still known only from the time it was first described.
Current Population Trend:Decreasing
Additional data:
Population severely fragmented:No

Habitat and Ecology [top]

Habitat and Ecology:It occurs in small cold-water streams in cloud forest. The eggs are laid on land and the male protects the eggs. When hatched the male carries the larvae on his back to water where they develop further.
Systems:Terrestrial; Freshwater

Threats [top]

Major Threat(s): Habitat loss and degradation due to agriculture (both crops and livestock) and road construction, is the major threat to the species. The locality is near the headwaters of a stream and thus could have been affected by a drought in the past. The species could also potentially be affected by disease, such as chytridiomycosis.

Conservation Actions [top]

Conservation Actions: There is a population within Parque Nacional Dinira. Surveys are urgently needed to determine the population status of this species as well as some of its threats.
