摘　　要：根据纤毛图式及细胞发生学特征 ,重新界定了腹毛目侧毛虫科纤毛虫 :侧毛虫、异毛虫、锥口虫、海尾柱虫、拟片尾虫以及拟翁口虫 6个相近属的定义。同时利用近祖 -衍化分析 ,探讨了其系统关系。According to the ciliary pattern as well as the morphogenetic information obtained today, the diagnosis and the general definition of six morphologically similar genera, Parurosoma, Ponturostyla, Onychodromopsis, Coniculostomum, Pleurotricha and Allotricha were revised and outlined. The results show that all taxa treated share the same character, i.e. possessing more than one marginal rows on at least one side, which represents, in the authors' opinion, a highly reliable and group dependent feature. Thus as a clearly outlined taxon(family) is qualified. An improved diagnosis is suggested: Sporadotrichina with more than one marginal rows on one or both sides. Based on morphological as well as morphogenetical data, the phylogenetic relationship among these taxa are discussed and described.
