Cells of the five isolated strains, JAMM 0394T, JAMM 0404T, JAMM 0415T, JAMM 0700 and JAMM 0738T, were Gram-negative, rod-shaped, non-sporulating and motile by means of a single polar flagellum. The novel strains were able to produce isoprenoid quinone Q-8 as the major component. The predominant fatty acids were C16 : 0 and C16 : 1. Phylogenetic analysis based on 16S rRNA gene sequences showed that the novel strains represent a separate lineage within the genus Psychromonas. The G+C contents of the novel strains were 38.8–42.8 mol%. DNA–DNA hybridization values between these strains and reference strains of the genus Psychromonas were significantly lower than that generally accepted as the threshold for the phylogenetic definition of species. The names Psychromonas japonica sp. nov. (type strain JAMM 0394T=JCM 14783T=ATCC BAA-1525T), Psychromonas aquimarina sp. nov. (type strain JAMM 0404T=JCM 14784T=ATCC BAA-1526T), Psychromonas macrocephali sp. nov. (two strains, type strain JAMM 0415T=JCM 14785T=ATCC BAA-1527T) and Psychromonas ossibalaenae sp. nov. (type strain JAMM 0738T=JCM 14786T=ATCC BAA-1528T) are proposed. %U https://www.microbiologyresearch.org/content/journal/ijsem/10.1099/ijs.0.65744-0
