In a study of marine ciliate diversity, we collected an Anteholosticha monilata-like population from Vietnam. To identify this population, we analyzed its morphology, some morphogenetic stages, and molecular phylogeny. Based on these data, we conclude that the Vietnamese population is new to science. Anteholosticha foissneri n. sp. resembles Anteholosticha monilata-like species considering (1) the number and arrangement of macronuclear nodules and micronuclei; (2) the presence of cortical granules; and (3) the saline habitat. However, the new species can be easily distinguished from these species by the arrangement, color, and shape of the cortical granules. The divisional morphogenesis commences with the de novo proliferation of basal bodies as a single longitudinal patch left of the posteriormost midventral cirral pair. This character state has not been reported before in Anteholosticha (based on check of the available data) and probably reflects a distinct clade within the nuclear small subunit ribosomal RNA gene tree.

在对海洋纤毛虫多样性的研究中，我们从越南收集了类似Anteholosticha monilata的种群。为了识别该种群，我们分析了它的形态，某些形态发生阶段和分子系统发育。根据这些数据，我们得出结论，越南人口是科学的新手。Anteholosticha foissneri ñ。sp。类似于Anteholosticha monilata-考虑到以下种类的物种：（1）大核结节和微核的数量和排列；（2）皮质颗粒的存在；（3）盐碱地。但是，可以通过皮质颗粒的排列，颜色和形状轻易地将这些新物种与这些物种区分开。分裂形态发生始于基体的从头增殖，即最后腹膜中央对的单个纵向斑块。以前尚未在Anteholosticha中报告过这种字符状态（基于对可用数据的检查），并且可能反映了核小亚基核糖体RNA基因树中的独特进化枝。
