A Gram-stain negative, non-flagellated, non-gliding and rod-shaped bacterium, strain JHH-2ᵀ, was isolated from seawater collected in Jeju Island, Korea. The novel isolate was found to grow at 25–30 °C, at pH 6.5–7.0 and in the presence of 1–2 % (w/v) NaCl. Phylogenetic analysis based on 16S rRNA gene sequences revealed that strain JHH-2ᵀ is closely related to Siansivirga zeaxanthinifaciens JCM 17682ᵀ, with 16S rRNA gene sequence similarity of 96.6 %. The predominant respiratory quinone was identified as menaquinone-6 and the major cellular fatty acids were detected as iso-C₁₅:₀, C₁₆:₀ and iso-C₁₇:₀ 3-OH. Polar lipid profiling revealed the presence of phosphatidylethanolamine, an unidentified glycolipid, four unidentified aminolipids and two unidentified lipids. The DNA G+C content of the chromosomal DNA of the type strain is 35.6 mol%. On the basis of several distinct phenotypic characteristics and phylogenetic analysis, a new species of the genus Siansivirga, Siansivirga jejunensis JHH-2ᵀ sp. nov. is proposed. The type strain is JHH-2ᵀ (= KCCM 92030ᵀ = JCM 19228ᵀ).
