Assessment Information [top]

Red List Category & Criteria: Data Deficient 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 Data Deficient in view of continuing doubts as to its taxonomic validity as well as absence of recent information on its extent of occurrence, status and ecological requirements.

Geographic Range [top]

Range Description:This species is known only from the type locality, the headwaters of the Pastaza River, in Napo Province, eastern Ecuador. The exact altitude of this site is unclear, though it is clearly a montane locality.

Population [top]

Population:This species has not been seen since the original collection in the 1940s, though this is probably related to the lack of survey effort, and its elusive nature.
Current Population Trend:Unknown
Additional data:
Population severely fragmented:No

Habitat and Ecology [top]

Habitat and Ecology:This is presumably a montane forest species. If it is similar to other species in its genus, it is an explosive breeder in ephemeral pools.
Systems:Terrestrial; Freshwater

Threats [top]

Major Threat(s): There is no precise information, owing to uncertainty relating to the exact location of the type locality.

Conservation Actions [top]

Conservation Actions: Its taxonomic status should be reviewed, in particular in relation to Ceratophrys cornuta (Cisneros-Heredia pers. comm.).
