Boone et al. (2001) assigned this genus to the family Enterobacteriaceae Rahn 1937 (Approved Lists 1980).Publication:
Garrity GM, Holt JG. The Road Map to the Manual. In: Boone DR, Castenholz RW, Garrity GM (eds), Bergey's Manual of Systematic Bacteriology, second edition, vol. 1 (The Archaea and the deeply branching and phototrophic Bacteria), Springer-Verlag, New York, 2001, p. 119-166.
This taxon name is occasionally misprinted in some sources as: "Rhanella"; "Ruhnella".
The phylogenomic assignment score of this taxon is 0.01070 (N = 6).
The BRCs most frequently used for deposits in this group are: LMG: 10; DSM: 9; NBRC: 3; KCTC: 1; JCM: 1; CCM: 1; ATCC: 1; CCUG: 1.
Pittman et al. (1991) suggested the abbreviation "RHNL" for this genus name but this does not appear to be of practical relevance any longer.Publication:

The genus Rahnella Izard et al. 1981 encompasses three genomospecies: GS 1 (Rahnella aquatilis sensu stricto), GS 2 and GS 3. It is not possible to phenotypically differentiate Rahnella aquatilis from the other genomospecies. So, the genomospecies 2 and 3 are not formally named.Publication:
