• Notes:
  • 🧕 Wang et al. (2025) assigned this genus to the family Sphingopyxidaceae 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: Sheu SY, Yang CC, Sheu DS, Tsai JM, Chen WM. Sphingomonas lacunae sp. nov., isolated from a freshwater pond. Int J Syst Evol Microbiol 2020; 70:5899-5910. 🇹🇼
  • ❗ Alterisphingopyxis 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: LMG: 1; BCRC: 1.
  • 🧍 The distinct name Alterisphingobium from the same publication has a similar spelling. — 🧍 The distinct name Alterisphingomonas from the same publication has a similar spelling.
