摘　　要：利用活体观察和银染技术,对采自广东省惠阳大亚湾沿岸的一种罕见海洋游仆类纤毛虫拟伍氏游仆虫Euplotes parawoodruffi进行了再研究,补充了有关活体形态学、性状变异以及分类学特征的统计学资料等。中国新纪录种拟伍氏游仆虫大亚湾种群与原报道种群存在细微差异,其主要特征为：口围带小膜数为60～70;体纤毛器数目及排布模式十分稳定：额腹棘毛9根,横棘毛5根,尾棘毛2根,左缘棘毛2根;背触毛恒为9列;大核近T形,形状多变。The morphology and infraciliature of a rare euplotid ciliate, Euplotes parawoodruffi Song and Bradbury, 1997, collected from the Daya Bay, Guangdong, South China, were investigated using live observation and silver impregnation methods. This isolate is very similar to the original description and hence only some additional information is supplied here： the living features and body variation, statistic data etc. This Chinese population of E. parawoodruffi is characterized by： body usually elliptical, some quadrate or triangular in outline, size in vivo 90-140 tan ×60-90 μm; adoral zone with about 60- 70 membranelles; constantly 9 frontoventral, 5 transverse, 2 caudal and 2 left marginal cirri; 9 dorsal kinedes; macronucleus T-shaped, with great shape variants.
