This species is known only from three localities in eastern and southeastern Brazil: Santa Teresa (type locality) and Cariacica in the State of Espírito Santo; and Jussari in the State of Bahia. It presumably occurs between these areas, and can be expected to occur at least a little more widely.
Habitat and Ecology
It is a forest species that cannot tolerate serious deforestation. Eggs are laid on leaves overhanging streams, and when hatched they fall in to the stream below where they develop further.
It is very common where it occurs. At the type locality it appears to have experienced a significant decline (Eterovick, et al., 2005).
The major threats are probably related to habitat loss due to agriculture, livestock grazing, and logging and human settlement.
It has been recorded from two protected areas: Reserva Particular do Patrimônio Natural Serra do Teimoso (Bahia); and Reserva Biólogica duas Bocas. Population monitoring is needed to determine wheter or not the species is in decline.
Red List Status
Least Concern (LC)
Listed as Least Concern in view of its relatively wide distribution, presumed large population, and because it is unlikely to be declining fast enough to qualify for listing in a more threatened category.
