Acanthocephalus parksidei Amin, 1974, was recently described from 11 species of Wisconsin fishes. Considerable variation was observed in this acanthocephalan's body size, number and arrangement of proboscis hook, size of hooks, proboscis, proboscis receptacle, lemnisci, embryos, testes, and cement glands, and number of the latter two. Most of these variations were related to worm sex and age as well as host species. Structural variations in the shape and lobation of lemnisci, abnormalities in hooks and body wall, and changes associated with monorchidism in males were noted. The significance of the erection of this new taxon in relation to the taxonomic criteria applied to acanthocephalan species is discussed.
帕克赛德棘头虫（Acanthocephalus parksidei），由阿明于1974年发现，近期在威斯康星州的11种鱼类中被描述。该棘头虫在体型、吻钩数量及排列、钩的大小、吻、吻鞘、系带、胚胎、睾丸和粘腺以及后两者的数量方面存在相当大的差异。这些差异大多与蠕虫的性别、年龄以及宿主种类有关。还注意到系带形状和叶状结构的结构变异、钩和体壁的异常以及雄性单睾症相关的变化。本文讨论了设立这一新分类单元相对于应用于棘头虫物种的分类标准的意义。
