Cucolepis gen. n. is erected as monotypic for Cucolepis cincta sp. n., a new species of cyclophyllidean cestode of the family Paruterinidae. The new species is described from the squirrel cuckoo, Piaya cayana Lesson (Aves: Cuculiformes), taken from two localities in Paraguay in 1984 and 1985. This new genus is most similar to the genus Triaenorhina Spasskii et Shumilo, 1965 in terms of the hook morphology and large epiphyseal structures extending from both the handle and guard, but differs in several aspects of the strobilar morphology, such as the shape of the cirrus sac, genital atrium, uterus and paruterine organ. The strobilar morphology of the new genus strongly resembles that of the genus Francobona Georgiev et Kornyushin, 1994, especially the shape of the cirrus sac and genital atrium, yet Francobona spp. lack, the developed epiphyseal structures observed in species of Cucolepis and Triaenorhina. Previous records and the nature of parasite-host associations between cuculiform birds and their cestode parasites are discussed.
新属Cucolepis是为单型属，以环带Cucolepis cincta sp. n. 为代表，它是副子宫科圆叶目绦虫的一个新物种。该新物种采自松鼠杜鹃Piaya cayana Lesson（鸟纲：杜鹃目），于1984年和1985年在巴拉圭的两个地点采集到。这个新属在钩的形态以及从柄部和护部延伸出的大型骨骺结构方面与1965年的Triaenorhina Spasskii et Shumilo属最为相似，但在节片形态的几个方面有所不同，如阴茎囊、生殖腔、子宫和副子宫器官的形状。新属的节片形态与1994年的Francobona Georgiev et Kornyushin属非常相似，尤其是阴茎囊和生殖腔的形状，然而Francobona属的物种缺乏在Cucolepis属和Triaenorhina属物种中观察到的发达的骨骺结构。文中还讨论了杜鹃目鸟类与其绦虫寄生虫之间的既往记录以及寄生虫 - 宿主关联的性质。
