This species is known from two areas in southeastern Brazil, from the vicinity of the city of Rio de Janeiro and Teresópolis in Rio de Janeiro State, and from the general vicinity of Santa Teresa (in Espírito Santo State) in southeastern Brazil. It is presumably more widespread, at least in the intervening regions. It occurs from near sea level up to at least 800m asl, perhaps higher.
Habitat and Ecology
This species is found in soil, or under the forest leaf-litter or under stones in primary forest, and also in plantations and rural gardens. It is assumed to be oviparous with terrestrial eggs and direct development, and not dependent on water for breeding.
This species is frequently encountered and is relatively easy to find.
Infrastructure development might be a localized threat, but it is adaptable is not generally at risk.
The range of the species in Espírito Santo State overlaps with the Parque Nacional da Jijuca and Parque Estadual da Pedra Branca. In Rio de Janeiro State it overlaps with the Reserva Biólogica Augusto Ruschi, Estacão Biólogica Santa Lucia and Parque Nacional Serra de Orgãos-Teresópolis.
Red List Status
Least Concern (LC)
Listed as Least Concern, although this species is currently known from only two locations (parts of which are within protected areas), its range is most likely much larger, it is abundant at these locations, and its population is not believed to be in decline.
This is a poorly circumscribed species in need of taxonomic review (M. Wilkinson pers. comm.).
