摘　　要：本文报道了采自江西省九江市武宁县花棚村池塘的中国淡水扁形动物单肠目达氏科小达氏涡虫属1新纪录种,即褐小达氏涡虫Microdalyellia fuscaFuhrmann,1894;详细描述了涡虫的形态特征,介绍了整装片标本的制作方法;同时比较了中国标本与产自德国的模式标本间的异同,其关键分类性状骨质阴茎的大体形态一致,但阴茎长度及其末端各分支的大小存在明显差异,推测是地理分布产生的品系间差别。所有标本保存在深圳大学生命科学学院。A newly recorded species, Microdalyellia fusca Fuhrmann 1894, of the genus Microdalyellia （ Platyhelminthes, Rhabdocoela, Dalyellidae） is reported from Asia in this paper. All specimens in this study are deposited in the College of Life Sciences, Shenzhen University, Guangdong, China. Microdalyellia fusca Fuhrmann, 1894.
