Scientific Name: Atelopus ignescens
Species Authority: (Cornalia, 1849)
Common Name(s):
English Quito Stubfoot Toad, Jambato Toad
Synonym(s):
Atelopus carinatus Andersson, 1945
Phryniscus laevis Günther, 1858
Taxonomic Source(s): Frost, D.R. 2014. Amphibian Species of the World: an Online Reference. Version 6 (27 January 2014). New York, USA. Available at: http://research.amnh.org/herpetology/amphibia/index.html. (Accessed: 27 January 2014).
Taxonomic Notes: Coloma, Lötters and Salas (2000) redefined Atelopus ignescens and restricted the species to the north-central Andes of Ecuador. Populations in northern Ecuador (in Cachi Province), and adjacent southern Colombia (Narino Department), previously assigned to Atelopus ignescens are now considered to belong to an undescribed species.

Assessment Information [top]

Red List Category & Criteria: Extinct ver 3.1
Year Published: 2004
Date Assessed: 2004-04-30
Annotations:
Needs updating
Assessor(s): Santiago Ron, Luis A. Coloma, Stefan Lötters, William Duellman, Martín R. Bustamante, Wilmar Bolívar, Enrique La Marca
Reviewer(s): Global Amphibian Assessment Coordinating Team (Simon Stuart, Janice Chanson, Neil Cox and Bruce Young)
Justification:
Listed as Extinct because it has not been recorded since 1988, and extensive searches over the last fifteen years have failed to locate this species.

Geographic Range [top]

Range Description: This species ranged from Imbabura to Chimborazo and Bolívar Provinces, in the Inter-Andean valleys and higher parts of the major Andean Cordilleras of Ecuador, at elevations of 2,800-4,200m asl.
Countries occurrence:
Regionally extinct:
Ecuador

Population [top]

Population: There have been no records of this species in Ecuador since 1988, despite extensive searches. It was formerly abundant along streams, but now appears to be extinct.
Additional data:
Population severely fragmented: No

Habitat and Ecology [top]

Habitat and Ecology: An inhabitant of humid montane forest, humid sub-páramo (high-altitude bushland), and páramo (high-altitude grassland). This was a stream breeding species. Animals were recorded from disturbed habitats, including modified grasslands, in the Inter-Andean valleys and residential areas close to Quito.
Systems: Terrestrial; Freshwater

Threats [top]

Major Threat(s): It probably disappeared due to the synergistic effects of the disease chytridiomycosis-confirmed in this species-and climatic change (local warming and droughts). Habitat loss and the introduction of predatory non-native trout might also have contributed to some population declines, however these threats are unlikely to have caused the substantial decline of the species throughout its range.

Conservation Actions [top]

Conservation Actions: The known range of this species overlapped with several protected areas, including: Reserva Ecológica Cayambe-Coca; Reserva Ecológica Antisana; Parque Nacional Cotopaxi; Area Nacional de Recreación el Boliche; Reserva Ecológica Los Illinizas; Parque Nacional Llanganates; and Reserva de Producción Faunística Chimborazo in Ecuador.
