A motile, rod-shaped, pale-brown-pigmented bacterium, designated strain C4, was isolated from seawater collected from the South Sea (Republic of Korea). Cells were Gram-negative, facultatively anaerobic, and catalase- and oxidase-positive. The major fatty acids were summed feature 3 (C 7 and/or iso-C 2-OH; 19.4 %), C (16.3 %), C 8 (9.5 %) and iso-C (7.7 %). The DNA G+C content was 40.8 mol%. A phylogenetic tree based on 16S rRNA gene sequences showed that strain C4 formed a lineage within the genus (92.7–96.1 % sequence similarity to representative strains of the genus ) and was part of a distinct branch with the clade comprising DW01 and ATCC 51192. Phenotypic characteristics enabled strain C4 to be distinguished from and . On the basis of the data presented in this study, strain C4 represents a novel species, for which the name sp. nov. is proposed. The type strain is C4 (=KCTC 22185=JCM 15074).
