Nomenclature of the subgenera Moraxella and Branhamella and of the nine species included in these subgenera and proposal to modify rule 34a of the Bacteriological Code (1990 Revision). Request for an opinion.

The subgenera Moraxella and Branhamella and the nine species included in these subgenera were inadvertently omitted from the Approved Lists of Bacterial Names and have never been revived according to Rule 28a of the Bacteriological Code (1990 Revision). The author requests that these names be revived and considered to be validly published in the 'Index of the bacterial and yeast nomenclatural changes published in the International Journal of Systematic Bacteriology since the 1980 Approved Lists of Bacterial Names (1 January 1980 to 1 January 1985)', which appears in the July 1985 issue of the International Journal of Systematic Bacteriology. Another problem is the status of the species included in the subgenera Moraxella and Branhamella because the Bacteriological Code (1990 Revision) does not envisage the status of a species transferred into a subgenus. The same is true for a species transferred into a subspecies. The author requests that such species be considered as new combinations and, according to this, proposes to modify Rule 34a of the Bacteriological Code (1990 Revision).
