Insperanos nattereri is a species of anostomid fish. It is found in the Rio Negro, Aleixo Lake, and the central Amazon basin in Brazil.[2] It is the only member of the genus Insperanos.[3] Prior to 2021, it was classified in the large genus Leporinus, but was moved to its own genus in 2021 after a phylogenetic analysis found it to represent an evolutionarily basal member of the subfamily. It is thought to be a relatively ancient genus, having diverged from the rest of the Leporininae during the Late Eocene, about 37 million years ago.[4]
Etymology
It is named in honor of Johann Natterer (1787-1843).[5]
