Term used in biological taxonomy for a "new combination"
Combinatio nova, abbreviated comb. nov. (sometimes n. comb.), is Latin for "new combination". It is used in taxonomic biology literature when a new name is introduced based on a pre-existing name. The term should not be confused with species nova, used for a previously unnamed species. The new combination replaces the superseded combination.
There are three situations:[1]
- the taxon is moved to a different genus
- an infraspecific taxon is moved to a different species
- the rank of the taxon is changed.
