A -like bacterium, strain KC7, was isolated from a marine crustacean specimen obtained from the Sea of Japan and subjected to a polyphasic study. Comparative 16S rRNA gene sequence analysis positioned the novel strain in the genus as an independent lineage adjacent to a subclade containing LMG 2142, EDIV and NBRC 15497. Strain KC7 shared highest 16S rRNA gene sequence similarity (96.1 %) with LMG 2142, DS-4 and NBRC 15497; similarities to strains of other recognized species were lower (96.0–93.9 %). The strain contained sphingoglycolipid and the predominant fatty acids were C, C and C; 2-OH C was the major 2-hydroxy fatty acid. Previously, these lipids have been found to be characteristic of members of the genus . On the basis of phylogenetic analysis and physiological and biochemical characterization, strain KC7 represents a novel species of the genus , for which the name sp. nov. is proposed. The type strain is KC7 (=KMM 3038 =NRIC 0738 =JCM 15438).
