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