1 The type genus "Cenarchaeum" does not appear on the Approved Lists of Bacterial Names, and has not been validly published since 1 January 1980. Consequently, Cenarchaeales Cavalier-Smith 2002 is illegitimate.
2 In the paper by Cavalier-Smith 2002, the type genus "Cenarchaeum" is erroneously cited as "Cenarchaeum" Preston et al. 1996.
