  • 💁 Taxonomists who have recently focused on this group are the corresponding authors of Zhu 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.
  • ❗ Halorarum 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: JCM: 3; CGMCC: 3.
