Deuterodon
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. These are small fish that reach up to 12.6 cm (5.0 in) in total length. They are omnivores with a specialized mouth structure that allows them to scrape algae and debris off bedrock.
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, though Myxiops was revalidated later.
