Phylogenetic analyses based on 16S rRNA gene sequences indicated that these bacteria were closely related to Vibrio superstes G3-29T (98.6–99.3 % sequence similarity). DNA–DNA hybridization and phylogenetic analysis based on the gapA gene demonstrated that six strains constituted one bacterial species, two strains represented a second species and one strain represented a third species. The three novel bacterial species were different from all currently known vibrios. The names Vibrio comitans sp. nov. (type strain GHG2-1T=LMG 23416T=NBRC 102076T; DNA G+C content 45.0–48.0 mol%), Vibrio inusitatus sp. nov. (type strain RW14T=LMG 23434T=NBRC 102082T; DNA G+C content 43.1–43.7 mol%) and Vibrio rarus sp. nov. (type strain RW22T=LMG 23674T=NBRC 102084T; DNA G+C content 43.8 mol%) are proposed to encompass these new taxa. Several phenotypic features were revealed that discriminate V. comitans, V. rarus and V. inusitatus from other Vibrio species. %U https://www.microbiologyresearch.org/content/journal/ijsem/10.1099/ijs.0.64789-0
