• Notes:
  • 🧕 Wang et al. (2025) assigned this genus to the family Sphingomicrobiaceae Wang et al. 2025. Publication: Wang Y, You H, Kong YH, Sun C, Wu LH, Kim SG, Lee JS, Xu L, Xu XW. Genomic-based taxonomic classification of the order Sphingomonadales. Int J Syst Evol Microbiol 2025; 75:6769. 🇨🇳
  • 🚂 For the type species of this genus another name is in use, which is affiliated with the genus Sphingomonas Yabuuchi et al. 1990. Publication: Asker D, Beppu T, Ueda K. Sphingomonas jaspsi sp. nov., a novel carotenoid-producing bacterium isolated from Misasa, Tottori, Japan. Int J Syst Evol Microbiol 2007; 57:1435-1441. 🇯🇵
  • 💁 Taxonomists who have recently focused on this group are the corresponding authors of Asker et al. (2007), Kang et al. (2021). Editors in search of reviewers are advised to consider additional criteria such as whether a taxon is covered by one of the ICSP subcommittees.
  • ❗ Pseudosphingomonas 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 phylogenomic assignment score of this taxon is 0.00687 (N = 4).
  • 🎰 The BRCs most frequently used for deposits in this group are: KCTC: 10; NBRC: 6; KACC: 5; JCM: 5; DSM: 5; CCUG: 2; CCTCC: 2; LMG: 2; CIP: 2; CGMCC: 1.
