  • This taxon name is occasionally misprinted in some sources as: "Ancyclobacter"; "Ancytobacter".
  • Taxonomists who have recently focused on this group are the corresponding authors of Doronina et al. (2022). Editors in search of reviewers are advised to consider additional criteria such as whether a taxon is covered by one of the ICSP subcommittees.

  • Pittman et al. (1991) suggested the abbreviation "AYBT" for this genus name but this does not appear to be of practical relevance any longer. Publication: Pittman KF, Walczak CA, Lock CM.

  • Replacement of the illegitimate name Microcyclus Ørskov 1928 (Approved Lists 1980), which is illegitimate because of precedence of the fungal genus Microcyclus Saccardo 1904 [Rule 51b (4)].
