Notes:
- The type species of this genus has alternatively been placed in the genus Enterobacter Hormaeche and Edwards 1960 (Approved Lists 1980).

Bacteriol. 1980; 30:569-584.
- This taxon name is occasionally misprinted in some sources as: "Chronobacter"; "Cromobacter".
- This taxon was discussed in a meeting of a Taxonomic Subcommittee of the ICSP. Publication: Holmes B, Farmer Iii JJ. International Committee on Systematics of Prokaryotes Subcommittee on the taxonomy of Enterobacteriaceae. Minutes of the meetings, 7 August 2008, Istanbul, Turkey. Int. J. Syst. Evol.

- Taxonomists who have recently focused on this group are the corresponding authors of Jackson et al. (2015), Stephan et al. (2014). Editors in search of reviewers are advised to consider additional criteria such as whether a taxon is covered by one of the ICSP subcommittees.
