anatinus

Anatinus is a taxonomic name that has appeared in some historical classifications as a proposed genus within the duck family (Anatidae). In current taxonomic practice, Anatinus is not recognized as a valid genus; major checklists do not maintain it, and any species formerly linked to Anatinus are typically assigned to Anas or other established genera. The exact circumscription and validity of the name have varied across sources, but it is generally regarded as obsolete in modern usage.

The name is derived from Latin roots commonly used in avian nomenclature for ducks, reflecting its intended relationship to anatids. The use of Anatinus illustrates historical attempts to reorganize duck diversity during periods of taxonomic change, before later revisions consolidated many species under better-supported genera.

Because Anatinus is not used in current taxonomy, there are no extant species formally listed under this genus in major databases. The term remains of interest mainly to historians of science and researchers examining the history of avian classification. Related topics include the family Anatidae and the genus Anas.
