Deuterodon is a genus of characins from river basins in southern and southeastern Brazil (Rio Grande do Sul to Espírito Santo), with a single species of uncertain taxonomic status, D. potaroensis, from Guyana.[1][2] These are small fish that reach up to 12.6 cm (5.0 in) in total length.[1] They are omnivores with a specialized mouth structure that allows them to scrape algae and debris off bedrock.[3]

Species formerly considered members of the genera Probolodus and Myxiops were considered to be members of Deuterodon by modern researchers, following a thorough phyletic review of several characid genera in 2020,[4] though Myxiops was revalidated later.
