Fig. 4 View Fig

Body elongated; greatest depth contained 3.2 to 3.3, and caudal peduncle depth 9.4 to 9.5 times in SL; head length 4.0, predorsal distance 2.0, caudal peduncle length 10.2 to 11.0 in SL; snout length 2.1 to 2.2, horizontal orbital diameter 4.9 to 5.1 and least interorbital width 2.3 in HL. Mouth terminal; premaxilla with three and dentary with four teeth, no maxillary teeth. Lateral line with 39- 41 pored scales; transverse series above lateral line with 7 scale rows and below with 5 or 5½ scale rows. Dorsal fin with 12, pectoral fin with 16 or 17, pelvic fin with 10, anal fin with 10 or 11 and caudal fin with 19 rays. Ground color yellowish; upper lip dark-brown; nine dark-brown transverse bars on body, one between orbits, one on nape, five on flank (usually Y-shaped), and two on caudal peduncle. Yellowish fins.

Maximum standard length. 410.0 mm.

Biological data. Lives in littoral and bathypelagic zones ( Freitas et al., 2009); it is a short-distance migratory species, with external fertilization, and does not display parental care ( Neuberger et al., 2009).

Distribution. Rio Tocantins and upper rio Paraná basins.

Remarks. Leporinus tigrinus has been captured in the upper rio Paraná floodplain since 2015 by Nupélia staff. Records of L. tigrinus were already reported to the upper rio Paraná basin by Langeani et al. (2007), Pavanelli et al. (2007) and Santos et al. (2013). Because museum specimens have not been captured in the basin before that, L. tigrinus is a possible non-native species in the region, probably introduced from the rio Tocantins basin ( Santos et al., 2013).
