Strains SW-46T and SW-52 were characterized chemotaxonomically by having ubiquinone-10 (Q-10) as the predominant respiratory lipoquinone and C18 : 1 ω7c as the major fatty acid. Their DNA G+C content was 64·0–64·1 mol%. Strains SW-46T and SW-52 showed 1 bp difference in their 16S rDNA sequences and a mean DNA–DNA relatedness level of 94·4 %. Phylogenetic analysis based on 16S rDNA sequences showed that strains SW-46T and SW-52 fall within the α-subclass of the Proteobacteria and form a coherent cluster with Erythrobacter longus, Erythrobacter litoralis and Erythrobacter citreus. Levels of 16S rDNA similarity between strains SW-46T and SW-52 and the type strains of these three Erythrobacter species were 96·5–97·9 %. Levels of DNA–DNA relatedness between strains SW-46T and SW-52 and the type strains of E. longus, E. litoralis and E. citreus were 3·6–14·7 %. Therefore, on the basis of phenotypic properties, phylogeny and genomic data, strains SW-46T and SW-52 should be placed in the genus Erythrobacter as a novel species, for which the name Erythrobacter flavus sp. nov. is proposed. The type strain is SW-46T (=KCCM 41642T =JCM 11808T)., UL https://www.microbiologyresearch.org/content/journal/ijsem/10.1099/ijs.0.02510-0
