• Notes:
  • 🧕 Chuvochina et al. (2023) assigned this family to the order Steroidobacterales Montecillo 2023. Publication: Chuvochina M, Mussig AJ, Chaumeil PA, Skarshewski A, Rinke C, Parks DH, Hugenholtz P. Proposal of names for 329 higher rank taxa defined in the Genome Taxonomy Database under two prokaryotic codes. FEMS Microbiol Lett 2023; 0:0.
  • 🧕 Montecillo (2023) assigned this family to the order Steroidobacterales Montecillo 2023. Publication: Montecillo JAV. Phylogenomics and molecular marker-based analyses of the order Nevskiales: proposal for the creation of Steroidobacterales ord. nov. and Peristeroidobacter gen. nov. Res Microbiol 2023; 174:104057.
  • 🚃 The type genus of this family has alternatively been placed in the family Nevskiaceae Henrici and Johnson 1935 (Approved Lists 1980). Publication: Naushad S, Adeolu M, Wong S, Sohail M, Schellhorn HE, Gupta RS. A phylogenomic and molecular marker based taxonomic framework for the order Xanthomonadales: proposal to transfer the families Algiphilaceae and Solimonadaceae to the order Nevskiales ord. nov. and to create a new family within the order Xanthomonadales, the family Rhodanobacteraceae fam. nov., containing the genus Rhodanobacter and its closest relatives.

  • 😢 The terminology used by the authors is in line with many other taxonomic studies and does not negatively affect their main results; some improvements may nevertheless be possible. Contrasting the term "chemotaxonomic" with "phenotypic" is not recommended. Using the term "phylogenetic data" (or equivalent) for sequence data is not advocated. Whether taxa can have "members" is debatable. See the LPSN phylogeny page for details. Publication: Göker M. What can genome analysis offer for bacteria? In: Bridge P, Smith D, Stackebrandt E (eds), Trends in the systematics of bacteria and fungi, CAB International, Wallingford, 2021, p. 255-281.
  • 🎰 The BRCs most frequently used for deposits in this group are: JCM: 8; KCTC: 6; DSM: 4; CGMCC: 3.
