Espinhos dorsais (total) : 0; Raios dorsais moles (total) : 0; Espinhos anais: 0; Raios anais moles: 34 - 38. Belly with 23 or 24 + 8 to 11, total 33 or 34 scutes. Lower jaw projecting; upper jaw with a toothed hypo-maxillary bone between hind tip of pre-maxilla and lower bulge of maxilla blade; lower gill rakers 12 to 14 (in fishes of 20 to 50 cm standard length).

Occurs in rivers, apparently not entering the sea, although presumably tolerating at least some salinity at the Amazon mouth. More data needed.
