Note: The type order "Aquificales" Reysenbach 2001 does not appear on the Approved Lists of Bacterial Names, and was not validly published when Cavalier-Smith proposed the class Epsilobacteria (January 14, 2002). The order ¤ Aquificales Reysenbach 2002 (previously known as "Aquificales" Reysenbach 2001) was validly published in the May 2002 issue of the IJSEM (Validation List no. 85). Consequently, Epsilobacteria Cavalier-Smith 2002 is illegitimate.
