homotypic synonym, validly published under the ICNP
According to Yarza et al. (2013), an "un-sequenced orphan species where descriptions, illustrations or dead preserved material serve as the type.".Publication:

In 2001, Neimark et al. proposed the transfer of Haemobartonella felis to the genus Mycoplasma with the Candidatus status: "CandidatusMycoplasma haemofelis" Neimark et al. 2001. The Candidatus designation is for new, incompletely described taxa, in order to give them a provisional status; changing validly published names to Candidatus would lose their standing in nomenclature. So, Neimark et al. revise "CandidatusMycoplasma haemofelis" to Mycoplasma haemofelis nom. nov. — For the transfer of Haemobartonella felis (ex Clark 1942) Kreier and Ristic 1984 to the genus Mycoplasma Nowak 1929 (Approved Lists 1980) it is necessary to substitute a new specific epithet to produce Mycoplasma haemofelis because the name Mycoplasma felis Cole et al. 1967 (Approved Lists 1980) already existed (Rules 34a and 41a).Publication:

Revision of the former classification as "CandidatusMycoplasma haemofelis".Publication:
Neimark H, Johansson KE, Rikihisa Y, Tully JG. Proposal to transfer some members of the genera Haemobartonella and Eperythrozoon to the genus Mycoplasma with descriptions of 'CandidatusMycoplasma haemofelis', 'CandidatusMycoplasma haemomuris', 'CandidatusMycoplasma haemosuis' and 'CandidatusMycoplasma wenyonii'. Int J Syst Evol Microbiol 2001; 51:891-899.
The full TRBA 466 classification is: risk group = 2, note = "t".
