Proposal of Allopseudospirillum gen. nov. as a replacement name for the illegitimate prokaryotic generic name Pseudospirillum Satomi et al. 2002.

The prokaryotic generic name Pseudospirillum Satomi et al. 2002 is illegitimate because it is a later homonym of Pseudospirillum Alexeieff 1917, a genus of uncertain affiliation, possibly belonging to the Mesomycetozoa (Principle 2 and Rule 51b(5) of the International Code of Nomenclature of Prokaryotes). We therefore propose the replacement generic name Allopseudospirillum, with type species Allopseudospirillum japonicum.
