Thermotogati is a kingdom of bacteria. They are united by the presence of an outer sheath-like membrane called a "toga".
Phylogeny The kingdom contains 3 valid and 2 candididate phyla:Parte, A.C., Sardà Carbasse, J., Meier-Kolthoff, J.P., Reimer, L.C. and Göker, M. (2020). List of Prokaryotic names with Standing in Nomenclature (LPSN) moves to the DSMZ. International Journal of Systematic and Evolutionary Microbiology, 70, 5607-5612; DOI: 10.1099/ijsem.0.004332
Notes: "Acetithermota" phylum as recorded by LPSN contains only one genus, "Candidatus Acetithermum". NCBI considers it a synonym of "Bipolaricaulota" per Hao et al. 2018. Neither LTP nor GTDB resolves current Thermotogati as a monophyletic group. The smallest group that includes all definitionally included phyla and sister groups are presented. Thermotogati and its now included phyla are shown in bold. Phylogenies below the phylum level are available on the pages for these individual phyla. The trees are extracted from phylum trees in pages The All-Species Living Tree Project and Branching order of bacterial phyla (Genome Taxonomy Database, 2018). They are subject to the disclaimers on these pages.

The proximity of Thermotogota to Synergistota is well-resolved in both trees. GTDB, which includes "Bipolaricaulota", supports its proximity to Deinococcota. However, the two trees do not appear to support the proximity between these two two-phylum groups.
Hao et al. (2018), using a CheckM genome tree constructed out of 43 marker genes, instead finds that "Bipolaricaulota" branches between Thermotogota and Synergistota, with Deinococcota branching relatively far away.
