摘要：
Sorubim maniradii, a new species, is described on the basis of 29 specimens from the middle and upper Amazon River Basin of Bolivia, Brazil, Ecuador, and Peru. This species is similar in morphology to S. lima and S. elongatus, but is distinguished from all congeners by its diffuse (versus conspicuously black) lateral stripe and high gill taker count (31-37 versus 13-23). It occurs sympatrically and syntopically with S. lima and S. elongatus.
