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. The term should not to be confused with species nova, used for a previously unnamed species.

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.

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.[2]

gollark: <@350812024055398401> Good question. I can't really test that very easily, since that's only done on the actual school-owned computers (personal devices you bring in and connect to their wifi network seem to have less restricted outbound access, though I'm sure they're logging as much as possible).
gollark: My school *does* MITM every connection made on the inschool computers! Yay!
gollark: Try Docker Compose next, it's very cool.
gollark: "Anyone suggesting security fixes is clearly a hacker and must be fired." - hopefully not.
gollark: Ah, a windows thing.
