This species is known from Parque Nacional do Itatiaia in Serra da Mantiqueira on the border of Rio de Janeiro and Minas Gerais States, in southern Brazil, from 1,800-2,400m asl, and possibly also from Castanhal Grande, Óbidos, Pará State, Brazil.
Habitat and Ecology
This diurnal species occurs in swamp areas along rivers with limpid and cold waters. It deposits its eggs in temporary puddles formed by the rain. It is not known whether or not it is able to adapt to habitat disturbance.
This is a very common species within its small range, but it appears to have declined recently (Eterovick et al. 2005).
Threats to this species include tourism and recreation.
The known range of the species is restricted to Parque Nacional do Itatiaia. More research is needed to confirm its extent of occurrence and whether or not it is a restricted range species. Conservation and maintenance of its habitat is also required, and population monitoring is needed to investigate an apparent decline.
Red List Status
Near Threatened (NT)
Listed as Near Threatened because, although its Extent of Occurrence is less than 5,000 km2, it occurs in a habitat that is not under significant threat, and so it is probably not in decline.
A strangely disjunct population from Óbidos, Pará State, Brazil, was described as a subspecies by Cochran (1948). Bokermann (1967) doubted the correctness of this locality and assumed that the specimens came from Itatiaia.
