Two new species of Dalyellidae, Dalyellia callvucurai n. sp. and Gieysztoria namuncurai n. sp., are described from temporary freshwater environments in central Buenos Aires Province, Argentina. The ultrastructure of the stylets of both species is also described. The new species of the genus Dalyellia is the second species of the genus found in the neotropics and the first whose stylet has been studied with scanning electron microscopy. Gieysztoria namuncurai n. sp. joins the seven species of the genus known in Argentina. The ultrastructural characteristics of the stylet place it in the Inaequales group, with complex stylets.
从阿根廷布宜诺斯艾利斯省中部的临时淡水环境中描述了两种新的戴氏涡虫科物种，即卡氏戴氏涡虫新种（Dalyellia callvucurai n. sp.）和纳氏吉氏涡虫新种（Gieysztoria namuncurai n. sp.）。还描述了这两个物种吻针的超微结构。戴氏涡虫属的这个新物种是在新热带地区发现的该属第二个物种，也是首个其吻针通过扫描电子显微镜进行研究的物种。纳氏吉氏涡虫新种加入了阿根廷已知的该属七个物种。吻针的超微结构特征使其归入具有复杂吻针的不等吻组。
