Known only from type locality and a locality 40 km away; type locality (Santos 1962) currently included in a park inside of Rio de Janeiro city, where it was last collected in 1966 (R.W. Garrison 2006); inferred continuing decline in quality of habitat due to human development in the area. Surveys to find if it occurs elsewhere along the eastern coastal area of Rio de Janeiro are needed; also studies on biology, trends and threats.
