Type genus
A genus whose name forms the basis of a family-group name and anchors that name to a name-bearing type species.
Taxonomic rank: A level in the hierarchical classification of organisms, such as genus, family, or order. A type genus connects the genus rank to the family rank.
Family-group name: A zoological name at the rank of superfamily, family, subfamily, tribe, or a related family-group rank. Type genera provide the stem from which family-group names are formed.
Hominidae: The family of great apes, including orangutans, gorillas, chimpanzees, bonobos, and humans. Homo is the type genus underlying this zoological family name.
Type genus (zoology): In zoological nomenclature, the genus that anchors a family-group name through its name-bearing type species. This zoological usage has rank-specific rules distinct from botanical family naming.
Genus: A taxonomic rank above species and below family, grouping closely related species. A type genus is a genus with a special role in family-group naming.
Principle of typification: The nomenclatural principle that links a name to a designated type rather than to a definition. The family name is anchored through the type genus, whose own name is anchored by a type species.
Felidae: The biological family of cats, including domestic cats, big cats, and their extinct relatives. Felis is the type genus whose name supplies the family name's stem.
Type genus (botany): In botanical nomenclature, the genus whose name is the basis of a family name. Botanical family names commonly use a prescribed ending, unlike zoological family-group names.
Family (biology): A taxonomic rank above genus and below order, grouping related genera. The family name is based on its type genus.
International Code of Zoological Nomenclature: The internationally adopted rules governing the scientific names of animals. Its family-group rules make the genus name the basis of the family name.
