Ichthyological terms, not general ones.
A nomenclatural concept denoted by an available name used in an original description, and based, actually or potentially, upon its name-bearing type but having no defined taxonomic boundaries. Often used when the precise definition of a species or genus is unclear, such as when a name may refer to more than one taxon and is therefore in need of clarification.

See nominal taxon.

Can be used to refer to any taxonomic group, the characteristics of which are used for defining related, higher or lower ranking groups. For example, the type of a nominal species is a specimen (type specimen), the type of a nominal genus is the nominal species (type species), and the type of a nominal family is the nominal genus (type genus).
