A marine, Gram-negative, deep-orange-coloured, rod/coccoid-shaped, strictly aerobic, non-motile, oxidase- and catalase-positive bacterial strain, designated YM6-073, was isolated from sediment collected in Okinawa, Japan. Strain YM6-073 produced the carotenoid (3,2′)-myxol. A phylogenetic analysis based on 16S rRNA gene sequences revealed that strain YM6-073 belonged to a distinct lineage in the family , the closest relative being HTCC2501 (93.7 % sequence similarity). Strain YM6-073 could be distinguished from other members of the family by means of a number of phenotypic characteristics. The DNA G+C content was 50.1 mol%. The predominant cellular fatty acids were iso-C, iso-C 10, iso-C 3-OH and C and menaquinone-6 was the only respiratory quinone. DNA–DNA hybridization between strain YM6-073 and DSM 15991 showed less than 10 % DNA–DNA relatedness. On the basis of phenotypic, genotypic and phylogenetic features, strain YM6-073 represents a novel species of the genus , for which the name sp. nov. is proposed. The type strain is YM6-073 (=MBIC 06409=KCTC 22216=DSM 21019).
