Catabasis acuminatus Eigenmann & Norris, 1900 Brycon acuminatus (Eigenmann & Norris, 1900) Brycon insignis, the Tiete tetra, is a species of fish in the family Characidae.

It is endemic to the Paraíba do Sul River basin in southeast Brazil.

[2] B. insignis migrates upstream to spawn and has traditionally been important to fisheries,[3] but it is now a threatened species.

[4] Some authorities recognize B. acuminatus as a separate, possibly extinct species,[5] but recent authorities treat it as a synonym of B.
