摘要
Eighteen named species of acoels have been reported from Japanese waters, though none from Hokkaido. Our faunal survey in Oshoro Bay, Hokkaido, revealed the presence of Oxyposthia praedator Ivanov, 1952, originally described from material collected in southwestern Sakhalin and subsequently recorded in the Gulf of Peter the Great. Molecular phylogenetic analysis based on the cytochrome c oxidase subunit I, 18S rRNA, and 28S rRNA genes indicates that O. praedator belongs to the family Convolutidae. However, its sister taxon could not be identified with high confidence. This is the first species-level identification of Acoela from Hokkaido and a new record of the species in Japan.

据报道，日本水域据报道有18种命名的Acoels种，尽管没有北海道。我们在北海道奥肖罗湾（Oshoro Bay）的动物群调查揭示了1952年的Oxyposthia praedator Ivanov，最初是从萨哈林西南部收集的材料中描述的，随后记录在彼得大帝的海湾中。基于细胞色素C氧化酶亚基I，18S rRNA和28S rRNA基因的分子系统发育分析表明，O. praedator属于家族。但是，无法充满信心地确定其姊妹分类单元。这是北海道的第一个物种水平的鉴定，也是日本物种的新记录。
