A new nemertean species of the genus Cephalothrix from intertidal calcareous red algae off the Vietnam coast is described based on histological sections, confocal laser scanning microscopy, and nucleotide sequences of three nuclear (18S rRNA, 28S rRNA, H3) and two mitochondrial (COI, 16S rRNA) DNA fragments. Cephalothrix suni sp. nov. is characterized by a unique body colour pattern consisting of transverse brown on ventral body side. A molecular phylogenetic analysis of the family Cephalotrichidae using a multigene approach has identified three clades for Cephalothrix: Cephalothrix, Procephalothrix, and interstitial cephalotrichids. The new species belongs to clade Procephalothrix sensu Chernyshev Kajihara 2019 and a subclade of species with red, orange, or dark yellow anterior tip.
描述了一种来自越南沿海潮间带钙质红藻的新Nemertean 属 Cephalothrix 物种，基于组织学切片、共聚焦激光扫描显微镜和三个核（18S rRNA、28S rRNA、H3）和两个线粒体（COI、16S rRNA）DNA 片段的核苷酸序列。Cephalothrix suni sp. nov. 的特征是独特的身体颜色模式，由腹侧的横向棕色组成。使用多基因方法对 Cephalotrichidae 科的分子系统发育分析确定了 Cephalothrix 的三个分支：Cephalothrix、Procephalothrix 和间生 Cephalotrichidae。新物种属于 Chernyshev Kajihara 2019 年定义的 Procephalothrix 分支以及具有红色、橙色或深黄色前端的物种的亚分支。
