• Notes:
  • 🚂 For the type species of this genus another name is in use, which is affiliated with the genus Novosphingobium Takeuchi et al. 2001. Publication: Lim YW, Moon EY, Chun J. Reclassification of Flavobacterium resinovorum Delaporte and Daste 1956 as Novosphingobium resinovorum comb. nov., with Novosphingobium subarcticum (Nohynek et al. 1996) Takeuchi et al. 2001 as a later heterotypic synonym. Int J Syst Evol Microbiol 2007; 57:1906-1908.
  • 💁 Taxonomists who have recently focused on this group are the corresponding authors of Niharika et al. (2013), Wang et al. (2025). Editors in search of reviewers are advised to consider additional criteria such as whether a taxon is covered by one of the ICSP subcommittees.
  • ❗ Pseudonovosphingobium is the correct name instead if this genus is regarded as a separate genus (i.e., if its nomenclatural type is not assigned to another genus whose name is validly published, legitimate and not rejected and has priority).
  • 🎰 The BRCs most frequently used for deposits in this group are: DSM: 17; JCM: 7; KCTC: 6; CCUG: 6; CCM: 6; CIP: 4; LMG: 4; MCCC: 3; KACC: 3; CGMCC: 3.
