In Brazil, the records are related to preserved areas, but unfortunately, those spaces still being affected by negatives influences. So, formal education to the population that lives near those areas and the park managers can start to change the situation.

Actions that are orientated to taxonomy and exploration to new sites need to be stimulated until a better understanding of this species status.
