Strain Ery12T showed high 16S rRNA gene sequences similarity to Tsuneonella flava MS1-4T (99.9 %), T. mangrovi MCCC 1K03311T (98.1 %), Altererythrobacter ishigakiensis NBRC 107699T (97.3 %) and exhibited ≤97.0 % sequence similarity with other type strains of species with validly published names. Growth was observed in media with 0–10.0 % NaCl (optimum 0–1.0 %, w/v), pH 5.0–9.5 (optimum 6.0–7.0) and 10–42 °C (optimum 30–37 °C). The predominant respiratory quinone was ubiquinone 10 (Q-10). The major cellular fatty acid was summed feature 8 (C18 : 1  ω7c and/or C18 : 1  ω6c). The major polar lipids were sphingoglycolipid, phosphatidyglycerol, diphosphatidylglycerol, phosphatidylethanolamine, phosphatidylcholine, three unidentified glycolipids, one unidentified aminoglycolipid and one unidentified lipid. The DNA G+C content was 60.8 %. The ANI and in silico DDH values between strain Ery12T and the type strains of its closely related species were 71.0- 91.8 % and 19.5- 44.6 %, respectively. According to the phenotypic, chemotaxonomic, phylogenetic and genomic data, strain Ery12T represents a novel species of the genus Tsuneonella , for which the name Tsuneonella suprasediminis is proposed. The type strain is Ery12T (=CGMCC 1.16500 T=MCCC 1A04421T=KCTC 62388T). We further propose to reclassify Altererythrobacter rhizovicinus and Altererythrobacter spongiae as Pelagerythrobacter rhizovicinus comb. nov. and Altericroceibacterium spongiae comb. nov., respectively. %U https://www.microbiologyresearch.org/content/journal/ijsem/10.1099/ijsem.0.004678
