Strain HWR-17T grew optimally at pH 7.0–8.0, at 30 °C and in the presence of 2 % (w/v) NaCl. Phylogenetic analyses based on 16S rRNA gene sequences showed that strain HWR-17T clustered with the two Mariniflexile species in the family Flavobacteriaceae, exhibiting 16S rRNA gene sequence similarity of 97.1–97.2 % to their type strains and less than 95.7 % sequence similarity to other members of the family Flavobacteriaceae. Strain HWR-17T contained MK-6 as the predominant menaquinone and iso-C15 : 0 as the major fatty acid. The polar lipid profile of strain HWR-17T contained phosphatidylethanolamine, an unidentified aminolipid and four unidentified lipids. The DNA G+C content of strain HWR-17T was 35.7 mol% and it exhibited 11 and 10 % DNA–DNA relatedness, respectively, with Mariniflexile gromovii KCTC 12570T and Mariniflexile fucanivorans DSM 18792T. The phylogenetic and genetic distinctiveness and differential phenotypic properties revealed that strain HWR-17T is distinguishable from the two recognized Mariniflexile species. On the basis of the data presented, strain HWR-17T is considered to represent a novel species of the genus Mariniflexile, for which the name Mariniflexile aquimaris sp. nov. is proposed. The type strain is HWR-17T ( = KCTC 23346T  = CCUG 60529T). An emended description of the genus Mariniflexile is also proposed. %U https://www.microbiologyresearch.org/content/journal/ijsem/10.1099/ijs.0.031492-0
