背鰭 (合計) : 13 - 14; 臀鰭: 11 - 12; 脊つい: 34 - 35. Can be differentiated from other members of the genus Leporinus by possessing 4 teeth on the premaxilla and 3 teeth on the dentary yielding the dental formula 4/3. Distinguished also from other species by the following combinations of non-unique characters: lateral line with 36-37 pored scales; transverse series of scales from origin of dorsal fin to lateral line 4; scales from lateral line to base of pelvic fin 4.5-5; series of scales around caudal peduncle 16; lateral line with 3 round dark blotches, the first at vertical through dorsal fin, the second at vertical through adipose-fin origin and the third at base of caudal peduncle (the latter two blotches, particularly the last one, usually small or inconspicuous) (Ref. 75002).
Adults inhabit lentic environments such as lagoons or borrow pits (Ref. 75002). Distinct pairs breed on densely grown weedy places (Ref. 205).
