A yellow-coloured bacterium, designated strain JGD-16T, was isolated from a tidal flat in Janggu-do, Garorim Bay, Taean-gun, Chungcheongbuk-do, Republic of Korea. Cells were Gram-stain-negative, aerobic, non-flagellated and short ovoid to coccoid-shaped. Growth was observed at 10–37 °C (optimum, 30 °C), pH 6.0–9.0 (pH 8.0) and with 1–5% (w/v) NaCl (2%). Results of 16S rRNA gene sequence analysis indicated that strain JGD-16T was closely related to Altererythrobacter xiamenensis LY02T (97.1 %), Altererythrobacter aurantiacus O30T (96.3 %), Altererythrobacter ishigakiensis JPCCMB0017T (95.8 %), Altererythrobacter epoxidivorans JCS350T (95.7 %) and Altererythrobacter insulae BPTF-M16T (95.3%). Phylogenomic analysis using the maximum-likelihood algorithm showed that strain JGD-16T formed a clade with the genus Altererythrobacter. The genomic DNA G+C content was 57.8 mol%. The predominant respiratory quinone was ubiquinone-10. The major polar lipids were diphosphatidyl-glycerol, phosphatidylethanolamine, phosphatidylglycerol, phosphatidylcholine, a sphingoglycolipid, an unidentified glycolipid and an unidentified lipid. The major fatty acids were C18:1 ω7c (31.5 %) and C18:3 ω6c (19.6 %). On the basis of its phylog-enomic, physiological and chemotaxonomical characteristics, strain JGD-16T represents a novel species within the genus Alter-erythrobacter, for which the name Altererythrobacter lutimaris JGD-16Tsp. nov. is proposed. The type strain is JGD-16T (=KCTC 72632T=KACC 21405T=JCM 33750T). We also propose the reclassification of Altererythrobacter deserti as Tsuneonella deserti comb. nov., Altererythrobacter estronivorus as Croceicoccus estronivorus comb. nov. and Altererythrobacter muriae as Alteripon-tixanthobacter muriae comb. nov.
