RA4-7T grew optimally at 25 °C, at pH 7.0–7.5 and in the presence of 2.0–3.0 % (w/v) NaCl. The phylogenetic trees based on 16S rRNA gene sequences showed that RA4-7T represented a member of the genus Polaribacter . RA4-7T exhibited 16S rRNA gene sequence similarity values of 97.64 and 97.23 % to Polaribacter atrinae WP25T and Polaribacter dokdonensis DSW-5T, respectively, and of 93.83–96.99 % to the type strains of the other species of the genus Polaribacter . RA4-7T contained MK-6 as the predominant menaquinone and summed feature 3 (C16 : 1ω7c and/or C16 : 1ω6c), iso-C15 : 0 3-OH and iso-C15 : 0as the major fatty acids. The major polar lipids detected in RA4-7T were phosphatidylethanolamine and one unidentified lipid. The DNA G+C content of RA4-7T was 30.5 mol% and its DNA–DNA relatedness values with the type strains of P. atrinae and P. dokdonensis were 16 and 11 %, respectively. Differential phenotypic properties, in combination with its phylogenetic and genetic distinctiveness, revealed that RA4-7T is separated from species of the genus Polaribacter with validly published names. On the basis of the data presented, RA4-7T represented a novel species of the genus Polaribacter , for which the name Polaribacterhaliotis sp. nov. is proposed. The type strain is RA4-7T (=KCTC 52418T=NBRC 112383T)., UL https://www.microbiologyresearch.org/content/journal/ijsem/10.1099/ijsem.0.001557
