  Notes:
  - Emendation accompanied by the proposal of 1 new species in the genus. — Emendation accompanied by the removal of 2 species from the genus.

List of changes in taxonomic opinion no. 25. Notification of changes in taxonomic opinion previously published outside the IJSEM. Int J Syst Evol Microbiol 2017; 67:7-8.
  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 expression "monophyletic clade" is a pleonasm. The phrase "validly described" is misleading. See the LPSN phylogeny page for details.
