通过活体观察、银浸渍和基于小亚基核糖体 rRNA (SSU rRNA) 的分子系统发育，对从中国东北淡水池塘收集的巨尾柱虫新种群进行了研究。此外，还通过扫描电子显微镜（SEM）和透射电子显微镜（TEM）方法仔细研究了其超微结构特征。提供了一些内部超微结构的补充描述，还发现了一些新的细胞器。特别是，首次通过SEM和TEM阐明了口腔内微管系统，并报道了一种新型挤出体。这些结果可能为尾柱属纤毛虫的分类学数据和摄入机制提供补充。
A new population of Urostyla grandis, collected from a freshwater pond of northeastern China was investigated by living observation, silver impregnation, and molecular phylogeny based on small subunit ribosomal rRNA (SSU rRNA). Besides, its ultrastructural characteristics were investigated carefully by scanning electron microscopy (SEM) and transmission electron microscopy (TEM) methods. Complementary descriptions of some inner ultrastructures were provided and some new organelles were also found. Especially, the oral inner microtubule system was illustrated by SEM and TEM for the first time and a new type extrusome was reported. These results may supply complement taxonomic data and ingestion mechanism on ciliates in genus Urostyla.
