Pseudomonasrhodos is the correct name if this species is regarded as a separate species within a separate genus Pseudomonas.
The specific epithet rhodos (sic) has been corrected in the new combination Methylobacterium rhodinum [see, Methylobacterium rhodinum corrig. (Heumann 1962) Green and Bousfield 1983, comb. nov.]. However the name "Pseudomonas rhodina" 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 rhodos (sic) has been maintained for Pseudomonas rhodos.Publication:
