• Notes:
  • 🚂 For the type species of this genus another name is in use, which is affiliated with the genus Nostocoides Deshmukh and Oren 2024. Publication: Deshmukh UB, Oren A. Proposal of Shuttleworthella gen. nov. and Nostocoides gen. nov. as replacement names for the illegitimate prokaryotic generic names Shuttleworthia and Tetrasphaera, respectively.

  • 🙄 This taxon name is occasionally misprinted (or affected by an OCR error) in some sources as: "Tertasphaera"; "Tetraspheara".
  • 💁 Taxonomists who have recently focused on this group are the corresponding authors of McKenzie et al. (2006). Editors in search of reviewers are advised to consider additional criteria such as whether a taxon is covered by one of the ICSP subcommittees.
  • 🎰 The BRCs most frequently used for deposits in this group are: JCM: 8; DSM: 7; NBRC: 4; NCIMB: 4; KCTC: 3; CIP: 2; ATCC: 2; VKM: 1; IFO: 1.
  • 😷 The risk group for Canada has been imported on 2024-02-27. The full classification is: risk group = 1, note = "Security sensitive biological agent: No - Terrestrial animal pathogen under Canadian Food Inspection Agency authority: No". — If in doubt, use the risk group given in the regulations for your country and, if these are not available, use the risk group given in the catalogue of the culture collection from which you have obtained or intend to obtain the strain.
  • 🧍 Illegitimate according to Principle 2 and to Rule 51b (4); the genus name Tetrasphaera Maszenan et al. 2000 is illegitimate because it is a later synonym of Tetrasphaera Popofsky 1912 (Protozoa, Sarcomastigophora, Sarcodina, Actinopoda, Polycystinea). Publication: Oren A, Arahal DR, Goker M, Moore ERB, Rossello-Mora R, Sutcliffe IC. International Code of Nomenclature of Prokaryotes. Prokaryotic Code (2022 Revision).
