摘　　要：利用非淹没培养皿法、活体观察法和蛋白银染色法,对采自甘肃临夏县和会宁县农田土壤的4种腹毛类纤毛虫,即柠檬管膜虫(Cyrtohymena citrina)、背触毛拟腹柱虫(Gastrostylides dorsicirratus)、沙栖蠕形尖毛虫(Vermioxytricha arenicola)和半残毛虫属一种(Hemisincirra sp.)进行了研究。结果表明,柠檬管膜虫、背触毛拟腹柱虫和沙栖蠕形尖毛虫为中国纤毛虫分布新记录种。半残毛虫属一种因缺失相关分类学、细胞发生学和分子学信息,此处暂作为未定名种处理。文中对4种纤毛虫的形态学特征进行了详细描述和讨论。Four species of hypotrichous ciliates isolated from farmland soils in Gansu,Cyrtohymena citrina(Fig.1 and 2),Gastrostylides dorsicirratus(Fig.3 and 4),Vermioxytricha arenicola(Fig.5﹣7)and Hemisincirra sp.(Fig.8 and 9),were studied morphologically using non-flooded Petri dish method,live observation and protargol staining methods.Among the species,C.citrine,G.dorsicirratus and V.arenicola are new record species of ciliates in China and H.sp.is kept as an unnamed form owing to the lack of some key taxonomic data and morphogenetic as well molecular information,which are required for accurate identification.Their morphological character were described in details and discussed.
