Basionym
Scientific name on which another scientific name is based / From Wikipedia, the free encyclopedia
In the scientific name of organisms, basionym or basyonym[1][2] means the original name on which a new name is based; the author citation of the new name should include the authors of the basionym in parentheses. The term "basionym" is used in both botany and zoology.[3] In zoology, alternate terms such as original combination[4] or protonym[5] are sometimes used instead. Bacteriology uses a similar term, basonym, spelled without an i.[6]
Although "basionym" and "protonym" are often used interchangeably, they have slightly different technical definitions. A basionym is the correct spelling of the original name (according to the applicable nomenclature rules), while a protonym is the original spelling of the original name.[5] These are typically the same, but in rare cases may differ.
