  • 🛺 The type order of this class has been placed in the class Deinococci Garrity and Holt 2002. Publication: Garrity GM, Holt JG. Class I. Deinococci class. nov. In: Boone DR, Castenholz RW, Garrity GM (eds), Bergey's Manual of Systematic Bacteriology, 2nd edn, vol. 1 (The Archaea and the Deeply Branching and Phototrophic Bacteria), Springer, New York, 2001, p. 395-403.

  • 🧍 Irregularly formed name (not formed from the stem of the name of the nomenclatural type). Name of the type order "Thermales" was not validly published at the time of publication. Rejected Name (Judicial Comm., Opinion 79 suppl.; IJSEM 64: 3599–3602). Publication: Tindall BJ.

  • 🧍 The type order "Thermales" Rainey and Da Costa 2001 does not appear on the Approved Lists of Bacterial Names, and was not validly published when Cavalier-Smith proposed the class Hadobacteria (January 14, 2002). The order Thermales Rainey and Da Costa 2002 (previously known as "Thermales" Rainey and Da Costa 2001) was validly published in the May 2002 issue of the IJSEM (Validation List no. 85). Consequently, Hadobacteria Cavalier-Smith 2002 is illegitimate. — Hadobacteria was previously known as "Hadobacteria" Cavalier-Smith 1992 emend. Cavalier-Smith 1998. Publication: Anonymous.
