    Notes:
    • ⊕ Emendation accompanied by the proposal of 2 new species in the genus.

• Notes:
  • 😢 The terminology used by the authors is in line with many other taxonomic studies and does not negatively affect their main results; some improvements may nevertheless be possible. The term "phylogenetic definition" is not recommended. Whether taxa can have "members" is debatable. See the LPSN phylogeny page for details. Publication: Göker M. What can genome analysis offer for bacteria? In: Bridge P, Smith D, Stackebrandt E (eds), Trends in the systematics of bacteria and fungi, CAB International, Wallingford, 2021, p. 255-281. 🇬🇧
  • 🎰 The BRCs most frequently used for deposits in this group are: JCM: 4; KCTC: 4; MCCC: 1; CICC: 1; KACC: 1; NBRC: 1.
  • 🧍 The Latin noun sphaera, cited in the etymology, is a L. fem. n., not a M.L. fem. n. as cited in the paper by Park et al. 2011. Publication: Euzeby JP. List of Bacterial Names with Standing in Nomenclature: a folder available on the Internet. Int J Syst Bacteriol 1997; 47:590-592. 🇫🇷
