Strain K-20<SUP>T</SUP>, a Gram-negative, nonmotile, nonspore-forming and strictly aerobic coccobacillus, which produces a pale pink pigment (R2A agar medium, 30℃, seven days) was isolated from a sample of biofilm obtained from a cooling tower in Tokyo, Japan. A phylogenetic analysis of the 16S rRNA partial gene sequences (1,439 bp) showed that the strain (accession number: AB297501) was related to <I>Roseomonas frigidaquae</I> CW67<SUP>T</SUP> and <I>Roseomonas stagni</I> HS-69<SUP>T</SUP> with 97.4% and 96.9% sequence similarity, respectively. Strain K-20<SUP>T</SUP> formed a distinct cluster with <I>Roseomonas frigidaquae</I> CW67<SUP>T</SUP> in the phylogenetic tree at a high bootstrap value (93%); however, distance was recognized between the strains. In addition, the DNA-DNA hybridization level between strain K-20<SUP>T</SUP> and <I>Roseomonas frigidaquae</I> JCM 15073<SUP>T</SUP> was 33%. The taxonomic data indicate that K-20<SUP>T</SUP> (=JCM 14634<SUP>T</SUP> =KCTC 32152<SUP>T</SUP>) should be classified in the genus <I>Roseomonas</I> as the type strain of a novel species, <I>Roseomonas tokyonensis</I> sp. nov.
