holotype
The single specimen designated as the name-bearing type of a nominal species or subspecies.
name-bearing type
In zoological nomenclature, the biological type (normally either a genus, species, or specimen) that determines how a name is applied.
neotype
A single specimen designated as the name-bearing type of a species subsequent to its description, most often when the holotype, lectotype, and syntype no longer exist.
nominal taxon
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.
paralectotype
In zoological nomenclature, any remaining member of a former syntype series following designation of a lectotype.
syntype
Any specimen within a type series if no holotype or lectotype has been designated, the syntypes collectively representing the name-bearing type.
type
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).
zoological nomenclature
Taxonomic system of scientific names for zoological taxa and the provisions for the formation, treatment, and use of those names. See ICZN.
