Diagnosis: This species differs from its congeners by the following combination of characters: squamation is reduced to axillar and caudal peduncle patches, unconnected or connected with single row along lateral midline; the anterior oculoscapular canal is present, ending anteriorly with or without pore ?; the preopercular canal is present (at least in a part of the population); the pelvic frenum has a crenate rear edge; suborbital longitudinal row b anteriorly beginning below rear border of eye; anterior dorsal row m is present; oculoscapular row u absent; single papilla of interorbital row p is present, at least in a part of a the population (Ref. 55951).
Body shape (shape guide): fusiform / normal.
Specimens were collected in a karstic river with fresh, oligotrophic, running water. The adults collected only in the main current at the greatest river depth (5.5 meter); bottom was clear gravel laterally becoming muddy; the juvenile (paratype) was collected in shallow waters, among vegetation (Ref. 55951).
