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.
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.
