Brycon insignis explained

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. B. insignis migrates upstream to spawn and has traditionally been important to fisheries,[1] but it is now a threatened species.[2]

Some authorities recognize B. acuminatus as a separate, possibly extinct species,[3] but recent authorities treat it as a synonym of B. insignis.[4]
