• Notes:
  • 📧 The e-mail address of the corresponding author given in the effective publication is not functional any more.
  • 😢 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 phrase "validly described" is misleading. Using the term "phylogenetic data" (or equivalent) for sequence data is not advocated. Whether taxa can have "members" is debatable. See the LPSN phylogeny page for details. Publication: Göker M. What can genome analysis offer for bacteria?

  • ❗ Thermotoga hypogea is the correct name instead if this species is regarded as a separate species (i.e., if its nomenclatural type is not assigned to another species whose name is validly published, legitimate and not rejected and has priority) within a separate genus Thermotoga.
