A Gram-staining-negative, yellow-pigmented bacterial strain, motile by gliding, designated HME7102T, was isolated from lagoon water in Korea. The phylogenetic tree based on 16S rRNA gene sequences showed that strain HME7102T formed a distinct lineage within the genus Flavobacterium. Strain HME7102T was closely related to Flavobacterium cheniae NJ-26T (94.5%), Flavobacterium dongtanense LW30T (94.4%) and Flavobacterium gelidilacus LMG 21477T (94.2%). The major fatty acids of strain HME7102T were iso-C15: 0, iso-C15: 1 G, iso-C17: 0 3-OH and iso-C15: 0 3-OH. The major polyamine was homospermidine and the major polar lipids were phosphatidylethanolamine, one unidentified aminolipid and two unidentified polar lipids. The DNA G+C content of strain HME7102T was 36.5 mol%. On the basis of the evidence presented in this study, strain HME7102T represents a novel species of the genus Flavobacterium, for which the name Flavobacterium jumunjinense sp. nov. is proposed. The type strain is HME7102T (5KCTC 23618T5CECT 7955T). Emended descriptions of F. cheniae, F. dongtanense and F. gelidilacus are also proposed. The genus Flavobacterium, type genus of the family Flavobacteriaceae, was proposed by Bergey et al. (1923) and subsequently emended by Bernardet et al. (1996) to include Gram-staining-negative, aerobic yellow-pigmented bacteria, predominantly motile by gliding with DNA G+C contents of 30–41 mol % and menaquinone 6 (MK-6) as the major respiratory quinone (Bernardet & Bowman, 2011). At the time of writing, the genus Flavobacterium comprises more than 85 specie
