• Notes:
  • ⏲ According to Zhou et al. (2020), this species is a later heterotypic synonym of Rufibacter ruber Kýrová et al. 2016. Publication: Zhou J, Ma WW, Qu JH, Li HF, Yang BB, Qu LB, Wang LF. Rufibacter hautae sp. nov., a red-pigmented bacterium from freshwater lake sediment, and proposal of Rufibacter quisquiliarum as a latter heterotypic synonym of Rufibacter ruber. Int J Syst Evol Microbiol 2020; 70:5950-5957.
  • 🏢 Synonymy of this taxon was mentioned in an IJSEM list. Publication: Oren A, Garrity GM. Notification list. Notification that new names and new combinations have appeared in volume 70, part 11 of the IJSEM. Int J Syst Evol Microbiol 2021; 71:4645.
  • 😢 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. 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.
  • ❗ Rufibacter quisquiliarum 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 Rufibacter.
  • 😷 The risk group for Germany has been imported on 2023-10-29. The full classification is: risk group = 1.
