The examined specimens have the diagnostic characters that allowed us to identify them as Leporinus tigrinus . They can be distinguished from its congeners from the Paraná River in Misiones (with the exception of Leporinus octofasciatus ) by the presence of dark brown bars across the body flank. It can be distinguished from L. octofasciatus by having 10 dark-brown vertical bars encircling the body in adults and at least one of these bars X or Y-shaped (vs. 8 vertical bars not encircling the body); the bright yellow color pattern of the body and fins (vs. reddish coloration); and for possessing 9 branched pelvic fin rays (vs. 8 rays).
