The alphaproteobacterial strain JLT2003(T) was isolated from surface seawater off the coast of Guishan island, Taiwan. The strain was Gram negative, ovoid or coccoid, non-motile and formed pink colonies on marine agar 2216 (MA; DIFCO) medium. The dominant fatty acids were C(18:1)ω7c, cyclo C(19:0)ω8c, and C(16:0). The polar lipid profile consisted of diphosphatidylglycerol and phosphatidylglycerol. The major respiratory ubiquinone was Q-10. The DNA G+C content was 62.3 mol%. Phylogenetic analysis based on 16S rRNA gene sequences showed that the strain was most closely related to Pontibaca methylaminivorans GRP21(T) with 94.8% similarity. The isolate was distinguishable from members of the family Rhodobacteraceae based on phenotypic and biochemical characteristics. On the basis of the taxonomic data presented, strain JLT2003(T) is considered to represent a novel species of a new genus, for which the name Oceaniovalibus guishaninsula gen. nov., sp. nov. is proposed. The type strain of Oceaniovalibus guishaninsula is JLT2003(T) (=JCM 17765(T) = CGMCC 1.10827(T)).
海洋弧菌属新种，命名为桂山岛海洋弧菌。桂山岛海洋弧菌（Oceaniovalibus guishaninsula）是一株革兰氏阴性、卵形或球形、非运动性、在海洋琼脂 2216（MA；DIFCO）培养基上形成粉红色菌落的α变形菌。其优势脂肪酸为 C（18：1）ω7c、环 C（19：0）ω8c 和 C（16：0）。极性脂由双磷脂酰甘油和磷脂酰甘油组成。主要呼吸醌为 Q-10。DNA G+C 含量为 62.3mol%。基于 16S rRNA 基因序列的系统发育分析表明，该菌株与甲基胺营养Pontibaca methylaminivorans GRP21（T）的相似度最高，为 94.8%。该分离株与红杆菌科的其他成员在表型和生化特征上有所不同。根据所提供的分类学数据，菌株 JLT2003（T）被认为代表了一个新属的新种，因此提议建立一个新属，名为桂山岛海洋弧菌属（Oceaniovalibus gen. nov.），其模式种为桂山岛海洋弧菌（Oceaniovalibus guishaninsula）。桂山岛海洋弧菌的模式株为 JLT2003（T）（=JCM 17765（T）=CGMCC 1.10827（T））。
