Taxonomy [top]

Kingdom Phylum Class Order Family

Scientific Name: Pristimantis scolodiscus
Species Authority: (Lynch and Burrowes, 1990)
Eleutherodactylus scolodiscus Lynch and Burrowes, 1990

Assessment Information [top]

Red List Category & Criteria: Endangered B1ab(iii) ver 3.1
Year Published: 2004
Date Assessed: 2004-04-30
Assessor(s): Fernando Castro, Maria Isabel Herrera, Santiago Ron, Luis A. Coloma, John Lynch
Reviewer(s): Global Amphibian Assessment Coordinating Team (Simon Stuart, Janice Chanson, Neil Cox and Bruce Young)
Listed as Endangered because its Extent of Occurrence is less than 5,000 km2, its distribution is severely fragmented, and there is continuing decline in the extent and quality of its habitat in the Colombian and Ecuadorian Andes.

Geographic Range [top]

Range Description: This species is known from a few localities at elevations of 1,200-1,780m asl in cloud forest on the Pacific slopes of the Andes in northern Ecuador (Carchi and Esmeraldas Provinces) and adjacent Colombia (Nariño Department). It might occur a little more widely.

Population [top]

Population: There is little information on the current population status of this species. However, it was observed and photographed in the mid-1990s in La Planada, Colombia.
Population Trend: Decreasing

Habitat and Ecology [top]

Habitat and Ecology: It is nocturnal, and is usually active on vegetation 1-3m above the ground, inside dense and undisturbed cloud forests. It may occur on vegetation along streams. The ability of this species to adapt to modified habitats is unknown. It is presumed to breed by direct development, but the site of egg deposition is not known.
Systems: Terrestrial; Freshwater

Threats [top]

Major Threat(s): The major threat is habitat loss caused by agricultural development (including the cultivation of illegal crops). Some other species of Eleutherodactylus that are associated with streams have undergone dramatic declines and disappearances, possibly due to chytridiomycosis, so the status of this species should be monitored carefully.

Conservation Actions [top]

Conservation Actions: In Colombia some populations of this species are distributed in La Planada National Reserve, while in Ecuador its geographic range overlaps with the Reserva Ecológica Cotacachi-Cayapas.
