A Gram-positive, rod-shaped or coccoid, yellow-pigmented bacterial strain, D287, was isolated from the water flea (Crustacea: Cladocera) collected from Lake Balaton in Hungary. Phylogenetic analysis on the basis of 16S rRNA gene sequence comparisons revealed that the strain represented a distinct lineage within the cluster of the genera and . The following characteristics were consistent with the affiliation of strain D287 to the genus : peptidoglycan based on -2,6-diaminopimelic acid, MK-8(H) as the major menaquinone, iso-C as the predominant cellular fatty acid, the presence of phosphatidylglycerol and diphosphatidylglycerol and a DNA G+C content of 69.9 mol%. Owing to characteristic differences in physiological traits and levels of 16S rRNA gene sequence similarity to its phylogenetically closest neighbours that were below 97 %, strain D287 is considered to represent a novel species of the genus , for which the name sp. nov. is proposed. The type strain is D287 (=DSM 18664=CCM 7403).
