  • 🧍 The transfer of Eperythrozoon coccoides (the type species of the genus Eperythrozoon) to the genus Mycoplasma means that the genera Eperythrozoon and Mycoplasma are heterotypic synonyms. According to Rule 44, the name of the genus must be Eperythrozoon because Eperythrozoon Schilling 1928 (Approved Lists 1980) has priority over Mycoplasma Nowak 1929 (Approved Lists 1980). In the paper by Neimark et al. 2005, the authors added a request for an Opinion concerning this problem. Consequently, according to Rule 28b(2), Mycoplasma coccoides (Schilling 1928) Neimark et al. 2005 is not validly published.

  • 🧍 Neimark et al. (2005) proposed to transfer Eperythrozoon coccoides Schilling 1928 (Approved Lists 1980) to the genus Mycoplasma Nowak 1929 (Approved Lists 1980) as ''Mycoplasma coccoides'' (Request for an Opinion, IJSEM 55:1385-1391). The Request was denied by the Judicial Commission of the International Committee on Systematics of Prokaryotes (Opinion 92., IJSEM 64:3586-3587).
