记述了两个种的形态和纤毛特征。11月和Paramagna Chen等人，2014年从中国东北部的一个淡水池中分离出来，用活体观察和银染方法对其进行了研究。11月由以下特征组合识别：淡水Frontonia，活体大小约220-350×130-250亩m，轮廓椭圆形；128-142个体细胞运动；3或4个前庭运动，6或7个后运动；1-3个各具4个运动的；单个可收缩的液泡，约有10个集合道。改进的诊断是基于当前和以前的报告。还提供了淡水Frontonia之间的比较。对这两个种的小亚基核糖体rRNA基因(SSU RDNA)序列进行了分析，根据这些序列进行的系统发育分析表明，这两个种都属于Frontonia属的核心沼泽地带，该属不是单系进化。(C)2018年爱思唯尔股份有限公司。版权所有。
The morphology and infraciliature of two Frontonia species, F. shii spec. nov. and F. paramagna Chen et al., 2014, isolated from a freshwater pond in northeastern China, were investigated using living observation and silver staining methods Frontonia shii spec. nov. is recognized by the combination of the following characters: freshwater Frontonia, size in vivo about 220-350 x 130-250 mu m, elliptical in outline; 128-142 somatic kineties; three or four vestibular kineties, six or seven postoral kineties; peniculi 1-3 each with four kineties; single contractile vacuole with about 10 collecting canals. The improved diagnosis for F. paramagna is based on the current and previous reports. Comparisons among freshwater Frontonia are also provided. The small subunit ribosomal rRNA gene (SSU rDNA) sequences of the two species are characterized and phylogenetic analyses based on these sequences show that both species fall into the core Glade of the genus Frontonia, and this genus is not monophyletic.
