Comments: Found in relatively small, clear water streams up to 1 m deep, with stones and rocks on bottom, and moderate riparian vegetation.  Collected at around 300 m above sea level.  Based on examination of several lots in fish collection, this species seems to occur only in mainstream of small rivers draining from Serra Geral formation, and was not found in the other subregion basin formed by lagoons of the Coastal Plain according to Malabarba & Isaia in 1992 (Ref. 96006).
