• 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. Publication: Göker M.
