Basionym

A basionym is the original name of a taxon on which a new combination (or name at new rank) is based. This term and its concept is confusing! An original, or base name, is not always a basionym. For example, Nupela frezelli is not a basionym; basionym is undefined. However, a taxon that has been transferred to a new genus does have a basionym. For example, Navicula mutica is the basionym of Luticola mutica.
