• Notes:
  • 🚂 For the type species of this genus another name is in use, which is affiliated with the genus Halomonas Vreeland et al. 1980. Publication: Lee JC, Jeon CO, Lim JM, Lee SM, Lee JM, Song SM, Park DJ, Li WJ, Kim CJ. Halomonas taeanensis sp. nov., a novel moderately halophilic bacterium isolated from a solar saltern in Korea. Int J Syst Evol Microbiol 2005; 55:2027-2032. 🇰🇷
  • 🧔 This taxon was discussed in a meeting of a Taxonomic Subcommittee of the ICSP. Publication: Oren A, Arahal DR, Ventosa A. International Committee on Systematics of Prokaryotes Subcommittee on the Taxonomy of Halobacteria and Subcommittee on the Taxonomy of Halomonadaceae: minutes of the joint open meeting, 25 November 2025, Oaxaca, Mexico. Int J Syst Evol Microbiol 2026; 76:7065. 🇮🇱
  • ❗ Onishia 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: CECT: 2; LMG: 2; KCTC: 1; CIP: 1; BH: 1; DSM: 1.
