Assessment Information [top]

Red List Category & Criteria: Critically Endangered B1ab(iii)+2ab(iii) ver 3.1
Year Published: 2004
Date Assessed: 2004-04-30
Assessor(s): Fernando Castro, John Lynch
Reviewer(s): Global Amphibian Assessment Coordinating Team (Simon Stuart, Janice Chanson, Neil Cox and Bruce Young)
Justification:
Listed as Critically Endangered because its Extent of Occurrence is less than 100km2 and its Area Of Occupancy is less than 10km2, all individuals are in a single location, and there is continuing decline in the extent and quality of its habitat.

Geographic Range [top]

Range Description: This species is known only from the region of the type locality, 8km east of Sonsón, in the Cordillera Central, in the department of Antioquia, Colombia, at 2,780m asl. It might be more widespread, but it is difficult at present to survey in surrounding areas due to security problems.

Population [top]

Population: It is known only from three specimens, and while there have been at least a dozen surveys of the type locality since its first description they have all failed to find the species. It has not been seen again since it was first described.
Population Trend: Decreasing

Habitat and Ecology [top]

Habitat and Ecology: The species was recorded on wet rocks very close to the surface of the stream in primary forest.
Systems: Terrestrial; Freshwater

Threats [top]

Major Threat(s): Unfortunately, the habitat of the type locality has been quite degraded, largely as a result of guerrilla activities.

Conservation Actions [top]

Conservation Actions: Further survey work is needed to confirm whether or not the species still survives at the type locality or if it occurs outside the vicinity of the type locality (although it is not a safe area to conduct fieldwork at present). If the species still survives, restoration and protection of its habitat will be necessary for its survival, since the type locality is not within any protected area.
