Cells were non-motile cocci showing oxidase- and catalase-positive activities. Growth of strain NAP41T was observed at 15–40 °C (optimum, 37 °C), at pH 6.5–9.0 (optimum, pH 7.0–7.5) and in the presence of 0.5–12 % (w/v) NaCl (optimum, 2 %). Strain NAP41T contained summed feature 8 (comprising C18 :  ω7c/C18 : 1 ω6c) and C18 : 0 as the major fatty acids and ubiquinone-10 as the sole isoprenoid quinone. Phosphatidylglycerol, phosphatidylcholine, phosphatidylethanolamine, an unidentified aminolipid and three unidentified lipids were detected as the polar lipids. The G+C content of the genomic DNA was 56.0 mol%. Strain NAP41T was most closely related to Primorskyibacter insulae SSK3-2T, Thalassococcus lentus YCS-24T and Roseivivax lentus DSM 29430T with 96.67, 96.39 and 96.39 % 16S rRNA gene sequence similarities, respectively, and formed a phylogenetic lineage distinct from closely related taxa within the family Rhodobacteraceae with low bootstrap values. On the basis of phenotypic, chemotaxonomic and molecular properties, strain NAP41T represents a novel species of a novel genus of the family Rhodobacteraceae , for which the name Aestuariicoccus marinus gen. nov., sp. nov. is proposed. The type strain of the type species is NAP41T (KACC 18431T=JCM 30739T). %U https://www.microbiologyresearch.org/content/journal/ijsem/10.1099/ijsem.0.002494
