• Notes:
  • 😩 Deposit incorrectly indicated in some sources as representing the type strain of this taxon: CIP 81.
  • ❗ Kocuria kristinae is the correct name instead if this species is regarded as a separate species (i.e., if its nomenclatural type is not assigned to another species whose name is validly published, legitimate and not rejected and has priority) within a separate genus Kocuria.
