Balantidium grimi n. sp. is described from the rectum of the frog Quasipaa spinosa (Amphibia, Dicroglossidae) from Lishui, Zhejiang Province, China. The new species is described by both light microscopy (LM) and scanning electron microscopy (SEM), and a molecular phylogenetic analysis is also presented. This species has unique morphological features in that the body shape is somewhat flattened and the vestibulum is "V"-shaped, occupying nearly 3/8 to 4/7 of the body length. Only one contractile vacuole, situated at the posterior body, was observed. The phylogenetic analysis based on SSU-rDNA indicates that B. grimi groups together with B. duodeni and B. entozoon. In addition, the genus Balantidium is clearly polyphyletic.
格氏小袋纤毛虫（Balantidium grimi）新种是在中国浙江省丽水市棘胸蛙（两栖纲，叉舌蛙科）的直肠中发现并描述的。该新种通过光学显微镜（LM）和扫描电子显微镜（SEM）进行描述，并进行了分子系统发育分析。该物种具有独特的形态特征，身体形状略扁平，前庭呈“V”形，占体长的近3/8至4/7。仅观察到一个位于身体后部的收缩泡。基于小亚基核糖体DNA（SSU-rDNA）的系统发育分析表明，格氏小袋纤毛虫与十二指肠小袋纤毛虫和内栖小袋纤毛虫聚为一类。此外，小袋纤毛虫属明显是多系的。
