从韩国大化港河河口采集了3种围生纤毛虫：Zoothamnium arcuatum n.sp.，Z.grossi n.sp.和Z.parahentscheli Sun等，2009年。在活体观察和银染的基础上对这些物种进行了调查，并对它们的小亚基(SSU)rRNA基因进行了测序。弓形动物可以通过杯状菌落、双层口周唇形和漏斗状多角体3(P3)的反常缩短的第3排来识别。罗氏动甲藻的形态特征是轮生分枝的茎，最低的次生茎从菌落主体分叉出来，不对称的钟形小兽，在P3中有三排短的平行的纤毛。系统发育分析表明，本文描述的三个种与兽科的其他成员聚在一起，符合预期。
Three peritrichous ciliates, Zoothamnium arcuatum n. sp., Z. grossi n. sp., and Z. parahentscheli Sun etal., 2009, were collected from an estuary of the Taehwagang River, Korea. All these species were investigated based on live observations and silver staining, and their small subunit (SSU) rRNA gene was also sequenced. Zoothamnium arcuatum can be identified by a goblet-shaped colony, double-layered peristomial lip, and abstomally shortened row 3 of infundibular polykinety 3 (P3). Zoothamnium grossi is morphologically characterized by an alternately branched stalk with the lowest secondary stalk diverging from the main part of colony, asymmetrically bell-shaped zooids, and three short, parallel ciliary rows in P3. Phylogenetic analysis revealed that the three Zoothamnium species described in this paper clustered with other members of the family Zoothamniidae, as expected.
