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. insignis.[6][7]
