Mouth terminal; premaxilla and dentary with 4 teeth, no maxillary teeth. Lateral line with 40-42 pored scales; transverse series above and below lateral line with 4½ scale rows. Dorsal and pectoral fin with 14 or 15, pelvic fin with 9, anal fin with 10 and caudal fin with 19 rays ( Britski et al., 2007). Ground color silvery; four black transverse bars on flank.

Remarks. Schizodon borellii  is a non-native species from the upper rio Paraná and its occurrence can be associated with the releasing of specimens in several reservoirs in the region for restocking (CESP, 1996; Júlio Júnior et al., 2009).
