Strombidiids are common free-living ciliates that have colonized coastal and open oceanic waters across the world. In recent years, numerous new taxa and gene sequences of strombidiids have been reported, revealing a large diversity of both their morphologic and genetic features. Here, we compare the taxonomic characters of all genera in the family Strombidiidae, provide a key to their identification, and investigate their molecular phylogeny. In addition, we analyze their regional distribution based on faunal data accumulated in China and attempt to infer their global distribution based on SSU rRNA gene sequence data. The current work revises the systematics of strombidiids based on morphologic, phylogenetic, and biogeographic evidence and provides a genus-level review of marine strombidiids.
陀螺虫是常见的自由生活纤毛虫，分布于全球沿海和开阔海域。近年来，已报道了许多陀螺虫的新分类单元和基因序列，揭示了它们在形态和遗传特征上的巨大多样性。在此，我们比较了陀螺虫科所有属的分类特征，提供了一个鉴定检索表，并研究了它们的分子系统发育。此外，我们根据中国积累的动物区系数据分析了它们的区域分布，并尝试根据小亚基核糖体RNA（SSU rRNA）基因序列数据推断它们的全球分布。目前的工作基于形态学、系统发育和生物地理学证据修订了陀螺虫的分类学，并提供了海洋陀螺虫的属级综述。
