This species is known only from the type locality, Bom Jardin da Serra, Sao Joaquim, Santa Catarina State, Brazil, at approximately 1,300m asl.
Habitat and Ecology
It is found on sphagnum moss in montane savannah. Its breeding habits are unknown, but the larvae presumably develop in water.
It is only known from a single collection in 1970. There have been few recent attempts to locate this species because it was only recently described.
The main threats to this species are probably the spread of pine plantations, overgrazing by cattle, and fires.
It occurs in Parque Nacional Sao Joaquín and Parque Estadual da Serra Furada.
Red List Status
Data Deficient (DD)
Listed as Data Deficient since it has only recently been described, and there is still very little information on its extent of occurrence, status and ecological requirements.
