Stevardiinae
Stevardiidae is a large Family (biology), family of freshwater fish in the Order (biology), order Characiformes. It includes many genera previously placed in the family Characidae, which was split into multiple families in 2024. They are found throughout South and Central America. In earlier taxonomic treatments, most genera in this family were placed in the characid subfamily Glandulocaudinae, which has been redefined as a much smaller subfamily of the Stevardiidae. As suggested by their former taxonomic name, a gland on their Fish anatomy, caudal fin is found almost exclusively in the males of many species of this family, which allows the release and pumping of Pheromone, pheromones. Members of this subfamily have complex courtship behaviors which lead to insemination. The ecology and life history of these fish is complex yet little studied. Stevardiids are important components of the diet for commercially-harvested larger fish. Taxonomy The following taxonomy is based on ''E ...

Eretmobrycon
''Eretmobrycon'' is a genus of characins found in Central and South America. Etymology eretmón (Gr. ἐρετμόν) means oar or paddle, referring to the paddle-like lower caudal-fin lobe of ''E. bayano''; brycon is a generalized term used in generic names of many characiform fishes, derived from brýchō (Gr. βρύχω), to bite, gnash teeth or eat greedily, originally an allusion to a fully toothed maxillae. Species There are currently 13 recognized species in this genus: * '' Eretmobrycon bayano'' W. L. Fink, 1976 * '' Eretmobrycon brevirostris'' ( Günther, 1860) * '' Eretmobrycon ecuadorensis'' ( Román-Valencia, Ruiz-C., Taphorn, Jiménez-Prado & García-Alzate, 2015) * '' Eretmobrycon emperador'' ( C.

Lophiobrycon
''Lophiobrycon weitzmani'' is a species of small characin endemic to Brazil, where it is found in the upper Paraná River basin. It is considered threatened by Brazil's Ministry of the Environment. This species is the only member of the genus ''Lophiobrycon'', but it is closely related to ''Glandulocauda'' and ''Mimagoniates'' (together they form the tribe Glandulocaudini).
