Phylogenetic analysis based on 16S rRNA gene sequences revealed that strain IMCC1962T belonged to the genus Eionea, forming a robust clade with members of the genus, and was most closely related to Eionea nigra (97.3  % similarity). DNA–DNA relatedness between strain IMCC1962T and Eionea nigra DSM 19752T was 21.8–26.3  %, which indicated strain IMCC1962T represents a novel genomic species of the genus Eionea. The G+C content of the DNA of strain IMCC1962T was 48.7 mol%. The major isoprenoid quinone was ubiquinone Q-8 and major fatty acids were C16 : 1ω7c and/or C16 : 1ω6c (43.4  %), C18 : 1ω7c and/or C18 : 1ω6c (19.3  %) and C16 : 0 (17.2  %). The polar lipids found in strain IMCC1962T were phosphatidylethanolamine, phosphatidylglycerol, aminophospholipid, unknown phospholipid, and four unknown polar lipids. Strain IMCC1962T and Eionea nigra DSM 19752T differed from each other in diverse phenotypic characteristics including motility, colony colour and enzyme activities. On the basis of phenotypic and genotypic data, strain IMCC1962T ( = KACC 17481T = NBRC 109703T) represents a novel species of the genus Eionea, for which the name Eionea flava sp. nov. is proposed. An emended description of the genus Eionea is also provided., UL https://www.microbiologyresearch.org/content/journal/ijsem/10.1099/ijs.0.000366
