J.P. Euzéby: List of Prokaryotic names with Standing in Nomenclature - Order Halobacteriales

Warning: In the List of Prokaryotic names with Standing in Nomenclature, an arrow (--->) only indicates the sequence of valid publication of names and does not mean that the last name in the sequence must be used (see: Introduction).

Classification - List of genera included in the order - List of families included in the order - Warning: see also the file "Classification of prokaryotes: Introduction".

Notes:
1 On the validation list n° 31, in violation of Rules 15 and 21a, the nomenclatural type is given as Halobacteriaceae Gibbons 1974 (Approved Lists 1980). It should be noted that the correct nomenclatural type is cited in the effective publication.

Opinion 79 in IJSEM Online
2 P. DasSarma & S. DasSarma 2008 [1], propose to rename the order Halobacteriales as "Haloarchaeales", to reflect its membership in the archaeal rather than the bacterial domain. This change is in violation of the General Considerations, Principles and Rules of the International Code of Nomenclature of Bacteria [2], and it not validly published.
