Body deep; greatest depth contained 1.3 to 1.5 and caudal peduncle depth 9.2 to 9.6 times in SL; head length 3.7 to 3.8, predorsal distance 1.4 to 1.6 and caudal peduncle length 17.4 to 20.0 in SL; snout length 2.6 to 3.6, horizontal orbital diameter 2.2 to 2.9 and least interorbital width 2.3 to 2.6 in HL. Mouth terminal; inner row of premaxilla with 4, outer row with 2; inner dentary row with 1, outer with 4; maxilla toothless. Lateral line complete, with 82-84 pored scales; transverse series above lateral line with 30-43 scale rows and below with 36-38 scale rows. Ventral keel with 30-33 simple spines, plus 3-5 slighlty bufurcate spines. Dorsal fin with 15-16, pectoral fin with 14-16, pelvic fin with 7, anal fin with 24-27, and caudal fin with 19 rays. Ground color silvery; black rounded humeral spot with diffuse limits; several deep-lying black spots over body; during reproductive period, several patches or stripes of red pigmentation appear mainly on ventral portion of body. Pectoral fin red, pelvic fin black in males and red in females; dorsal fin with black blotch and sparse patches of red pigmentation; anal fin hyaline; caudal fin hyaline, except for dark-grey margin ( Graça, Pavanelli, 2007).

Maximum standard length. 170.2 mm ( Graça, Pavanelli, 2007).

Distribution. Drainages of Venezuela and French Guiana, Amazon basin, drainages of Northeastern Brasil, rio São Francisco and upper rio Paraná basins ( Ota, 2015).

Remarks. Metynnis lippincottianus is a possible non-native species from the upper rio Paraná, and its occurrence can be associated with the releasing of specimens for restocking, or with the aquarium trade ( Ota, 2015).
