• Notes:
  • ❗ Halobacteroides acetoethylicus 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 Halobacteroides.

  • 🧍 The specific epithet acetoethylicus (sic) has been corrected in the new combination Halanaerobium acetethylicum [see, Halanaerobium acetethylicum corrig. (Rengpipat et al. 1989) Rainey et al. 1995, comb. nov.]. However the name "Halobacteroides acetethylicus" corrig. has never been formally proposed before December 14, 2000 (date of publication of the amended Rule 61; see Int. J. Syst. Evol. Microbiol., 2000, 50, page 2239, column 2). Consequently, in the "List of Prokaryotic names with Standing in Nomenclature", the epithet acetoethylicus (sic) has been maintained for Halobacteroides acetoethylicus.
