This species is known only from the type locality, Parque Florestal do Itapetinga, Atibaia, in São Paulo State, Brazil. This locality is at around 800m asl. It probably occurs at least a little more widely.
Habitat and Ecology
Individuals were found in a small, clean, cold montane rivulet in forest, and larvae were found in deeper pools.
The population status is unknown, this species is only known from a few specimens.
Habitat loss due to human settlement and fire might be threats to this species.
A similar species (Megaelosia cf. boticariana) has recently tested positive for Batrachochytrium dendrobatidis infection (Toledo et al., 2006b).
Parque Florestal do Itapetinga is the only protected area from which it is currently known.
