从我国近海沃茨中分离到3种刺甲藻，分别为触手刺甲藻Tintinnopsis tentaculata Nie and Cheng，1947，东方刺甲藻Tintinnopsis orientalis Kofoid and坎贝尔，1929和绿刺甲藻Eutinnus lususundae（Entz，1885）Kofoid and坎贝尔，1939。每个形态进行了调查的基础上观察的活标本和protargol染色，并分析了它们的SSU rDNA和LSU rDNA为基础的系统发育关系。这些物种的纤毛图案是第一次揭示。根据本研究的原始描述和数据，对每个物种进行了改进的诊断。与其同类不同，Eutintinnus lusussuundae的第二背动肌移位到左睫状野下方，这可能表明第二背动肌正在通过迁移过程进化为后动肌。重新定义了Eutintinnus的腹侧运动。确定了T. tentaculata在客观上稳定了种名，主要是因为模式材料的不可用。(C)2019 Elsevier GmbH.

Three species of tintinnines, namely Tintinnopsis tentaculata Nie and Cheng, 1947, Tintinnopsis orientalis Kofoid and Campbell, 1929, and Eutintinnus lususundae (Entz, 1885) Kofoid and Campbell, 1939, were isolated from coastal waters of China. The morphology of each was investigated based on observations of live and protargol-stained specimens, and their SSU rDNA- and LSU rDNA-based phylogenetic relationships were analyzed. The ciliary patterns of these species are revealed for the first time. Based on the original descriptions and data from the present study, an improved diagnosis is given for each species. Unlike its congeners, the second dorsal kinety of Eutintinnus lususundae is displaced below the left ciliary field, which may suggest that the second dorsal kinety is evolving into a posterior kinety by a migration process. The ventral kinety in Eutintinnus is redefined. A neotype is fixed for T. tentaculata to stabilize the species name objectively, mainly because of the unavailability of type material.
