The second part is from the Greek (opsis = relating to sight and appearance); hence, resembling a hypoptopomatine fish. The species name biamnicus From the Latin bi, meaning two, and amnicus, meaning inhabitant of a river, in allusion to the fact that the species is distributed in both the Iguaçu and Tibagi basins.
