Assessment Information [top]

Red List Category & Criteria: Endangered B1ab(iii)+2ab(iii) ver 3.1
Year Published: 2010
Date Assessed: 2008-11-07
Assessor(s): Luis A. Coloma, Santiago Ron, Diego Cisneros-Heredia
Reviewer(s): Global Amphibian Assessment Coordinating Team (Simon Stuart, Janice Chanson, Neil Cox and Bruce Young)
Listed as Endangered, in view of its extent of occurrence of less than 5,000 km2 and area of occupancy of less than 500 km2, with all individuals in five locations, and a continuing decline in the extent and quality of its habitat.
Previously published Red List assessments:
2004 Endangered (EN)

Geographic Range [top]

Range Description: This species is known from four localities on the Amazonian slopes of the Andes in Río Salado and the Cascada de San Rafael, Napo Province, Ecuador, and from 35 km southwest of San Francisco, Putumayo department, Colombia. It is found at altitudes of 1,300-1,900m asl.
Countries occurrence:
Colombia (Colombia (mainland)); Ecuador
Lower elevation limit (metres): 1300
Upper elevation limit (metres): 1900

Population [top]

Population: It is known to be rare; it was last recorded in 1979 and searches in 1999-2001 failed to turn up any individuals (Bustamante, 2002). However, the sampling effort throughout its range has probably been insufficient.
Current Population Trend: Decreasing
Additional data:
Population severely fragmented: No

Habitat and Ecology [top]

Habitat and Ecology: It lives in cloud forest. The holotype was found in a bromeliad in the spray zone of a waterfall and on a cliff (Lynch and Duellman, 1973). It lays its eggs on vegetation, and the larvae develop in water.
Systems: Terrestrial; Freshwater

Threats [top]

Major Threat(s): Habitat destruction and degradation, as a result of agriculture and logging, are the main threats to this species. It is possible that chytridiomycosis may also have contributed to the decline. Predictions suggest that in Ecuador, almost half of the habitats suitable for this species have been deforested (Cisneros-Heredia, 2008).

Conservation Actions [top]

Conservation Actions: Its distribution may overlap marginally with the Reserva Ecológica Cayambe-Coca. Improved protection of the montane forest habitat in the range of this species is necessary. Given the possible threat of chytridiomycosis, surveys are needed to determine this species' current population status.
