• Notes:
  • ⏲ According to Summers et al. (2020), this species is a later heterotypic synonym of Thermotoga petrophila Takahata et al. 2001. Publication: Summers ZM, Belahbib H, Pradel N, Bartoli M, Mishra P, Tamburini C, Dolla A, Ollivier B, Armougom F. A novel Thermotoga strain TFO isolated from a Californian petroleum reservoir phylogenetically related to Thermotoga petrophila and T. naphthophila, two thermophilic anaerobic isolates from a Japanese reservoir: Taxonomic and genomic considerations. Syst Appl Microbiol 2020; 43:126132.
  • 🏢 Synonymy of this taxon was mentioned in an IJSEM list. Publication: Oren A, Garrity GM. List of changes in taxonomic opinion no. 34. Notification of changes in taxonomic opinion previously published outside the IJSEM. Int J Syst Evol Microbiol 2021; 71:4816.
  • ❗ Thermotoga naphthophila is the correct name instead if this species is regarded as a separate species (i.e., if its nomenclatural type is not assigned to another species whose name is validly published, legitimate and not rejected and has priority) within a separate genus Thermotoga.
