• Notes:
  • 🥇 Nomenclatural type of the genus Neffella Silva Cerqueira et al. 2026. Publication: Silva Cerqueira AE, Holley JC, Hatcher SC, Vidigal PMP, Phillips LE, Moran NA.

  • 😢 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 expression "monophyletic clade" is a pleonasm. 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. 🇬🇧
