半鞭毛虫是一种海洋鞭毛虫，以硅藻和甲藻等为食。虽然以前对其形态和超微结构进行了观察和表征，但尚未利用分子序列数据分析其系统发育位置。根据线粒体中的动泡体的存在，这种鞭毛虫被归类为动质体。然而，也注意到了一些类似于双线虫的形态特征，双线虫是动质体的姐妹群。在此，我们报告。通过分析18S rRNA基因序列构建的系统发育树中双线粒分支中的胞囊分支。在此基础上，对其系统定位进行了讨论。
Hemistasia phaeocysticolais a marine flagellate that preys on diatoms and dinoflagellates among others. Although its morphology and ultrastructure were previously observed and characterized, its phylogenetic position has not been analyzed using molecular sequence data. This flagellate was classified as a kinetoplastid on the basis of the presence of a kinetoplast in the mitochondrion. However, several morphological characteristics similar to those of diplonemids, a sister group of kinetoplastids, have also been noted. Herein, we report thatH. phaeocysticolabranches within the diplonemid clade in the phylogenetic tree reconstructed by analyzing 18S rRNA gene sequences. Its systematic placement based on this finding is also discussed.
