Combinatio nova

Combinatio nova, abbreviated comb. nov. (sometimes n. comb.), is Latin for "new combination". It is used in life sciences literature when a new name is introduced based on a pre-existing name.

There are three situations:

• the taxon is moved to a different genus
• an infraspecific taxon is moved to a different species
• the rank of the taxon is changed.

Examples

When an earlier named species is assigned to a different genus, the new genus name is combined with of said species, e.g. when Calymmatobacterium granulomatis was renamed Klebsiella granulomatis, it was referred to as Klebsiella granulomatis comb. nov. to denote it is a new combination.
