We characterized six tintinnid ciliates from Antarctic waters using molecular markers and morphological traits: Amphorellopsis quinquealata, Codonellopsis gaussi, Cymatocylis convallaria, Cy. calyciformis, Cy. drygalskii, and Laackmanniella prolongata. The 100% similarity in SSU-ITS1-5.8S rDNA-ITS2-partial LSU rDNA sequences among Cy. convallaria, Cy. calyciformis, and Cy. drygalskii is supportive of synonymy. Codonellopsis gaussi and L. prolongata also showed high levels of similarity in SSU rDNA (99.83%) and the D2 domain of LSU rDNA (95.77%), suggesting that they are closely related. Phylogenetic analysis placed Cymatocylis in the Rhabdonellidae, Amphorellopsis in the Tintinnidae and L. prolongata/Co. gaussi within the Dictyocystidae.
五旋钟虫、高斯拟尾柱虫、旋纹钟虫、具缘钟虫、干氏钟虫和延长拟尾柱虫。旋纹钟虫、具缘钟虫和干氏钟虫的 SSU-ITS1-5.8S rDNA-ITS2-部分 LSU rDNA 序列的 100%相似性支持它们是同物异名。高斯拟尾柱虫和延长拟尾柱虫的 SSU rDNA（99.83%）和 LSU rDNA 的 D2 结构域（95.77%）也表现出高度相似性，表明它们密切相关。系统发育分析将旋纹钟虫归入了织纹滴虫科，五旋钟虫归入了钟形虫科，而延长拟尾柱虫/高斯拟尾柱虫归入了胶须虫科。
