Comments: Collected from caves within the São Domingos karst region in the upper portions of the Rio Tocantins basin.  The species occur in both subterranean and surface drainages and appears to be well adapted to epigean habitats as indicated by the overall condition and sexual maturity of the individuals from cave habitats (Ref. 84053).
