''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 to be confused with ', used for a previously unnamed species.
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.

Klebsiella granulomatis'', it was referred to as ''Klebsiella granulomatis comb. nov.'' to denote it was a new combination.
