Assessment Information [top]

Red List Category & Criteria: Critically Endangered (Possibly Extinct) B2ab(i,ii,iii,iv,v) ver 3.1
Year Published: 2004
Date Assessed: 2004-04-30
Needs updating
Assessor(s): Luis A. Coloma, Santiago Ron
Reviewer(s): Global Amphibian Assessment Coordinating Team (Simon Stuart, Janice Chanson, Neil Cox and Bruce Young)
Listed as Critically Endangered because its Area of Occupancy is probably less than 10km2, its distribution is severely fragmented, and there is a continuing decline in its Extent of Occurrence, in its Area of Occupancy, in the extent and quality of its habitat, in the number of locations, and in the number of mature individuals.
Date last seen: 1960s

Geographic Range [top]

Range Description:This species was known from the inter-Andean valleys of Guayllabamba, Toachi, Chimbo, and Cañar, and on the western slopes of the Andes in northern and central Ecuador, where it occupied areas between 1,500 and 3,800m and was known from more than ten localities.

Population [top]

Population:There are no records of this species since the 1960s. Bustamante (2002) provides data of its absence at Bosque Protector Cashca Totoras (Provincia Bolívar), where it used to be a common frog. It is possible that undetected relict populations might still survive.
Current Population Trend:Decreasing
Additional data:
Population severely fragmented:No

Habitat and Ecology [top]

Habitat and Ecology:It lives in mid- to high-elevation humid montane forest (Coloma 1995). It lays its eggs on the ground, and males carry the eggs to small streams for development.
Systems:Terrestrial; Freshwater

Threats [top]

Major Threat(s): The primary threat to this species is habitat destruction and degradation due to agriculture, clear cutting, and human settlement; virtually no habitat remains where this species used to occur. Invasive alien species are also a threat.

Conservation Actions [top]

Conservation Actions: The distribution range of the species overlaps Reserva Ecológica Los Illinizas, Reserva Geobotánica Pululahua, and Reserva de Producción Faunística Chimborazo. Surveys are urgently required to determine the population status and continued persistence of this species.
