Pristella is a genus of freshwater ray-finned fishes belonging the family Acestrorhamphidae, the American characins. It was formerly a monotypic taxon only containing Pristella maxillaris , but in 2019 a second species, Pristella ariporo, was described. ^[2]

Taxonomy

Until 2019, Pristella was a monotypic genus, but P. ariporo was described in 2019. Additionally, Hyphessobrycon axelrodi may belong in Pristella due to its conical teeth, but further genetic studies are needed to confirm this. ^[2]

Species

Pristella contains the following valid species: ^{[2] [3] [4]}
