<jats:p>
Small-subunit (SSU) rRNA gene sequences associated with the phylum
<jats:named-content content-type="genus-species">Armatimonadetes</jats:named-content>
were analyzed using multiple phylogenetic methods, clarifying both the phylum boundary and the affiliation of previously ambiguous groupings. Here we define the
<jats:named-content content-type="genus-species">Armatimonadetes</jats:named-content>
as 10 class-level groups and reclassify two previously associated groups as candidate divisions WS1 and FBP.
