Salminus hilarii, the tabarana, is a species of freshwater ray-finned fish belonging to the family Bryconidae, the doradas and jaw characins. This fish is found in Argentina, Brazil and Paraguay.

[2] This species is classified in the genus Salminus which is the only genus in the subfamily Salmininae which is one of two subfamilies in the family Bryconidae. [3] The family Bryconidae is part of the suborder Characoidei in the order Characiformes. [4]
Salminus hilarii is classified in the genus Salminus, a name which suffixes -inus onto the Latin name for salmon, Salmo . This is an allusion to the salmon like body hape and adipose fin of S. brevidens , the type species of the genus. The specific name, honours the French botanist Auguste de Saint-Hilaire, the collector of the holotype. [5]
