Seven marine scuticociliates, Philaster sinensis spec. nov., Pseudocohnilembus hargisi Evans and Thompson, 1964. J. Protozool. 11, 344, Parauronema virginianum Thompson, 1967. J. Protozool. 14, 731, Uronemella filificum (Kahl, 1931. Tierwelt. Dtl. 21, 181) Song and Wilbert, 2002. Zool. Anz. 241, 317, Cohnilembus verminus Kahl, 1931, Parauronema longum Song, 1995. J. Ocean Univ. China. 25, 461 and Glauconema trihymene Thompson, 1966. J. Protozool. 13, 393, collected from Chinese coastal waters, were investigated using live observations, silver impregnation methods, and, in the case of the new species, SSU rDNA sequencing. Philaster sinensis spec. nov. can be recognized by the combination of the following characters: body cylindrical, approximately 130-150 × 35-55 μm in vivo; apical end slightly to distinctly pointed, posterior generally rounded; 19-22 somatic kineties; M1 triangular, consisting of 13 or 14 transverse rows of kinetosomes; M2 comprising 10-12 longitudinal rows; CVP positioned at end of SK1; marine habitat. We also provide improved diagnoses for Pseudocohnilembus hargisi, Parauronema virginianum, Uronemella filificum and Parauronema longum based on their original descriptions as well as the present work. Phylogenetic analyses support the monophyly of the genus Philaster.
从中国沿海水域采集到7种海洋盾纤毛虫，分别为中华菲氏藻（新物种）、哈氏伪科氏藻（埃文斯和汤普森，1964年，《原生动物学杂志》第11卷，第344页）、弗吉尼亚副尾丝虫（汤普森，1967年，《原生动物学杂志》第14卷，第731页）、丝状尾丝虫（卡尔，1931年，《德国动物志》第21卷，第181页；宋和威尔伯特，2002年，《动物学通报》第241卷，第317页）、短小科氏藻（卡尔，1931年）、长形副尾丝虫（宋，1995年，《中国海洋大学学报》第25卷，第461页）和三膜绿藻（汤普森，1966年，《原生动物学杂志》第13卷，第393页），采用活体观察、银浸染法以及（对于新物种）小亚基核糖体DNA测序进行研究。中华菲氏藻新物种可通过以下特征组合识别：身体呈圆柱形，活体时大小约为130 - 150×35 - 55μm；顶端稍尖至明显尖，后端通常圆形；19 - 22条体动基列；M1呈三角形，由13或14排横向动基体组成；M2由10 - 12排纵向动基体组成；胞咽沟位于SK1末端；海洋生境。我们还根据其原始描述以及当前研究对哈氏伪科氏藻、弗吉尼亚副尾丝虫、丝状尾丝虫和长形副尾丝虫进行了改进诊断。系统发育分析支持菲氏藻属的单系性。
