本文报道了四种海洋盾纤毛虫--秀丽侧丝藻新种Pleuronema elegans spec. nov.刚毛假单胞菌P. setigerum Calkins，1902，葛氏假单胞菌P. grolierei Wang et al.，2008和东方尾丝藻（Uronema orientalis spec. nov.）采用活体观察和蛋白银染色法对采自中国近海的10种鱼类进行了调查。秀丽侧丝藻新种Pleuronema elegans spec. nov.的特征为：体细胞大小90-115 × 45-60 µm，细长椭圆形，后端明显尖，尾纤毛长约10条，口前动丝2条，体动丝18 - 19条，膜2a双列，后端直，膜3三列，大核1个，体细胞10条，体细胞海洋栖息地东方尾丝藻（Uronema orientalis spec. nov.）的特征是：体细胞大小约40-55 × 20-30 μm，顶板截短;体细胞动力体20个;膜1个，单列，分为两部分，分别由4个和3个基体组成;第二个体细胞动力体末端有可收缩的空泡孔;海洋生境。我们还提供了改进的诊断为P. grolierei Wang等，2008和P. setigerum Calkins，1902基于当前和以前的报告。U. orientalis、P. elegans、P. grolierei和P. puytoraci进行测序。系统发育分析表明，尾丝属和侧丝属不是单系的。
The morphology and infraciliature of four marine scuticociliates, Pleuronema elegans spec. nov., P. setigerum Calkins, 1902, P. grolierei Wang et al., 2008 and Uronema orientalis spec. nov., collected from China seas, were investigated through live observation and protargol staining methods. Pleuronema elegans spec. nov. can be recognized by the combination of the following characters: size in vivo 90–115 × 45–60 µm, slender oval in outline with a distinctly pointed posterior end; about 10 prolonged caudal cilia; consistently two preoral kineties and 18 or 19 somatic kineties; membranelle 2a double-rowed with its posterior end straight; membranelle 3 three-rowed; one macronucleus; marine habitat. Uronema orientalis spec. nov. is distinguished by the following features: in vivo about 40–55 × 20–30 μm with a truncated apical plate; consistently twenty somatic kineties; membranelle 1 single-rowed and divided into two parts which comprise four and three basal bodies respectively; contractile vacuole pore positioned at the end of the second somatic kinety; marine habitat. We also provide improved diagnoses for P. grolierei Wang et al., 2008 and P. setigerum Calkins, 1902 based on current and previous reports. The small subunit rRNA gene of U. orientalis, P. elegans, P. grolierei and P. puytoraci were sequenced. Phylogenetic analyses indicate that Uronema and Pleuronema are not monophyletic.
