Principle of Coordination
In zoology, the Principle of Coordination is one of the guiding principles of the International Code of Zoological Nomenclature.
It states that the act of publishing a new zoological name thereby automatically and simultaneously establishes all the corresponding names in the relevant other ranks, with the same type.
In the species-group, publishing the species name Giraffa camelopardalis Linnaeus, 1758 also establishes the subspecies name Giraffa camelopardalis camelopardalis Linnaeus, 1758. The same applies to the name of a subspecies; this establishes the corresponding species name.
In the genus-group, similarly, publishing the name of a genus also establishes the corresponding name of a subgenus : Giraffa Linnaeus, 1758 and Giraffa Linnaeus, 1758 ;. In the family-group, publication of the name of a family, subfamily, superfamily also establishes the names in all the other ranks in the family group.
Author citations for such names are the same as for the name actually published. It is immaterial if there is an actual taxon to which the automatically established name applies; if ever such a taxon is recognised, there is a name available for it.
