Contracaecum spasskii Mozgovoi, 1950, collected from the great crested grebe Podiceps cristatus (Linnaeus) (Podicipediformes: Podicipedidae), is redescribed using both light and, for the first time, scanning electron microscopy. Contracaecum spasskii differs from its congeners by having marked transverse cuticular annulations, the length of the oesophagus and spicules, the ratio between the intestinal caecum and the ventricular appendix, the number and arrangement of male caudal papillae, and especially by the particular morphology of the lips and interlabia. Some previously unreported morphological features of C. spasskii are also revealed and others corrected. Contracaecum rudolphii Hartwich, 1964 (sensu lato) is also redescribed based on the specimens collected from the great cormorant Phalacrocorax carbo sinensis (Blumenbach) (Pelecaniformes: Phalacrocoracidae) from China. Based on the geographical perspective, the present Chinese material may represent the species C. rudolphii B.
1950年从风头鸊鷉Podiceps cristatus（林奈）（鸊鷉目：鸊鷉科）采集到的斯氏对盲囊线虫Contracaecum spasskii Mozgovoi，首次使用光学显微镜和扫描电子显微镜进行重新描述。斯氏对盲囊线虫与其同属线虫的区别在于具有明显的横向角质环纹、食管和交合刺的长度、肠盲囊与心室附属物的比例、雄性尾乳突的数量和排列，尤其是唇部和阴唇间的特殊形态。还揭示了斯氏对盲囊线虫一些以前未报道的形态特征，并纠正了其他一些特征。基于从中国的普通鸬鹚Phalacrocorax carbo sinensis（布吕门巴赫）（鹈形目：鸬鹚科）采集的标本，对1964年的鲁氏对盲囊线虫Contracaecum rudolphii Hartwich（广义）也进行了重新描述。从地理角度看，目前的中国材料可能代表鲁氏对盲囊线虫C. rudolphii B物种。
