Abstract
The classification of the Rickettsiales is discussed for taxa above species. A new Class, Microtatobiotes, meaning smallest life, is proposed to include Orders Rickettsiales and Virales. Other new proposals are: Tribe Wolbachiae under Rickettsiales including two new genera Symbiotes (genotype Rickettsia lectularia Arkwright et al.) and Rickettsiella (genotype Coxiella popillae Dutky and Gooden). Extensive new synonymy is provided in genera and species under Rickettsia, Coxiella, Cowdria, Miyagawanella, and Wolbachia.
