Two marine, heterotrophic, aerobic, pigmented and gliding bacteria, isolated from the sea urchin Strongylocentrotus intermedius were subjected to a polyphasic taxonomy study. The 16S rRNA gene sequence analysis revealed that strains KMM 6032T and KMM 6047 formed a distinct branch within the genus Arenibacter, a member of the family Flavobacteriaceae. The level of sequence similarity between the novel isolates and members of the genus Arenibacter was 94.5–98.9 %. The DNA G+C content was 39–40 mol%. The dominant fatty acids were iso-C15 : 1, iso-C15 : 0, C15 : 0, C15 : 1{omega}6c, iso-C15 : 0 3-OH, iso-C17 : 1{omega}9c, iso-C17 : 0 3-OH and summed feature 3 (comprising iso-C15 : 0 2-OH and/or C16 : 1{omega}7c). The results of DNA–DNA hybridization experiments supported by phenotypic data indicated that the isolates represent a novel species within the genus Arenibacter, for which the name Arenibacter echinorum sp. nov. is proposed. The type strain is KMM 6032T (=KCTC 22013T=LMG 22574T).

The GenBank/EMBL/DDBJ accession numbers for the 16S rRNA gene sequences of strains KMM 6032T and KMM 6047 are EF536748 and EF536749, respectively.
