homotypic synonym, validly published under the ICNP
Neisseriaovis is the correct name 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 Neisseria.
However, the type strain was not cited [see Rule 27(3)] and this new combination did not appear in the Notification List published in the July 1993 issue of the IJSB .Publication:
Lists Editor I. Notification that new names and new combinations have appeared in IJSB. Int. J. Syst. Bacteriol. 1993; 43:625.
In the April 1993 issue of the IJSB, M. Véron et al.  proposed that Neisseria ovis should be called Branhamella ovis.Publication:
