Assessment Information [top]

Red List Category & Criteria: Critically Endangered (Possibly Extinct) B2ab(iii,v) ver 3.1
Year Published: 2004
Date Assessed: 2004-04-30
Needs updating
Assessor(s): Carlos Frederico da Rocha, Monique Van Sluys, Carlos Alberto Gonçalves da Cruz
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, all individuals are in a single sub-population, and the extent and quality of its habitat, and the number of mature individuals, on the Itatiaia Mountains in southern Brazil are declining.
Date last seen: 1976

Population [top]

Population:This species was found frequently up until the 1970s, but has not been found for more than 10 years even though there have been extensive searches of the area for many years. It was last collected in 1976.
Current Population Trend:Decreasing
Additional data:
Population severely fragmented:No

Habitat and Ecology [top]

Habitat and Ecology:This species occurs on the ground, under mulch and leaves, which is also where the eggs are laid. It hides under stones and in terrestrial bromeliads in open grassland, and probably breeds by direct development.

Threats [top]

Major Threat(s): The species has been heavily impacted by habitat degradation due to touristic activities and fire, and is also affected by extreme frosts.

Conservation Actions [top]

Conservation Actions: The range of the species is within Parque Nacional do Itatiaia, and continued conservation and maintenance of its habitat is necessary. More exhaustive searches for this species are needed, in order to determine whether or not it still survives in the wild. If it is found, then further conservation measures, including a conservation management plan, will be needed.
