Known only from type locality, which is currently included in a park within Rio de Janeiro city (Santos 1965). Never recorded again, and therefore considered as extinct by Machado and Brescovit (2005), but that could be due to lack of surveys designed to find it which are urgently needed. Doubtful generic placement also needs to be analyzed.
