  • 🧍 Considered not validly published (informal proposal for replacement name). Publication: Oren A, Arahal DR, Christensen H, Goker M, Manaia CM, Moore ERB. International Code of Nomenclature of Prokaryotes. Prokaryotic Code (2025 Revision). Int J Syst Evol Microbiol 2026; 76:6979. 🇮🇱
  • 🧍 The authors did not expliclty assign a nomenclatural type but since the class is suggested to form the nomenclatural type of the phylum Nitrospiraeota for replacing the phylum Nitrospira (Nitrospirae), Nitrospirales is the obvious choice.
