这种吸虫最初是由英国的科博尔德在1859年从一只死在伦敦动物园的美国红狐的胆管中发现的例子中命名的。后来，在1872年，刘易斯和坎宁安，并在1876年，麦康奈尔记录了其他吸虫在这个相同的名称;这些后来，然而，指的是物种后睾吸虫noverca。1899年，洛斯建立了一个新属--次睾吸虫属，并将这种吸虫归入其中。同时在1894年，斯泰尔斯和哈塞尔描述了一种来自美国猫的吸虫，命名为Distoma complexurn;它后来被归为Parametalus属。这是区别于本物种的事实，卵黄腺跨越肠盲囊，满足前面的髋臼。副蜜环鱼属的主要特征是卵黄腺在“玫瑰花”形子宫前面的结合;蜜环鱼属也有一个“玫瑰花”形子宫，卵黄腺在两个独立的侧群中。“玫瑰花结”一词不应太过字面理解;它指的是一个管状的子宫，线圈堆积在自己身上，或多或少围绕着髋臼，与后睾的起伏形式形成对比。1926年，洪描述了一种来自猫的吸虫，他称之为Parameteris noveboracensis。1929年，Price根据Law和Kennedy在加拿大收集的材料，描述了分别来自银狐和水貂的中间型P. intermedius和加拿大型P. canadensis; 1934年，艾伦和沃德尔描述了来自狗的Manitobensis。所有这些都可以根据在各种描述时检查的标本相互分离。然而，当一个大的系列是可用的，不同的主机感染实验从同一来源，差异消失，所有似乎是科博尔德的Distoma结膜的同义词。然而，所有这些都被归为Parametalus属。我一直找不到任何特征来证明科博尔德的物种在任何属以外的Metabolis。这使得Parametalus属只有一个物种，P. complexus，其特征是卵黄的结合。1934年，徐氏在中国描述了与猫尾蝠（M. felis）近缘但又有区别的猫尾蝠（Metabolis felis）。白纹鲨因此，在哺乳动物中，Metabolis属现在有三个物种，M。albidus，M. felis和M.产于北美洲的合生种。它们都有非常相似的特征，并且都有明确的地理分布。此外，它们还可以在形态学上区分如下：
This trematode was originally named by Cobbold in England in 1859 from examples found in the bile ducts of an American Red Fox which died in the London Zoological Gardens. Later, in 1872 Lewis and Cunningham, and in 1876, McConnell recorded other flukes under this same name; these were later, however, referred to the species Opisthorchis noverca. In ,1899, Looss established a new genus, Metorchis, in which he placed this trematode. Meanwhile in 1894, Stiles and Hassall described a fluke from a cat in the United States under the name of Distoma complexurn; it was later placed in the genus Parametorchis. This is distinguished from the present species by the fact that the yolk glands cross the intestinal caeca to meet anterior of the acetabulum. The main character of Parametorchis was this union of the yolk glands anterior to the "rosette"-shaped uterus; the genus Metorchis, which also had a "rosette"-shaped uterus, had the yolk glands in two separate lateral groups. The word "rosette" should not be taken too literally; it refers to a tubular uterus, with coils heaped up on themselves and more or less surrounding the acetabulum, contrasted with the undulating form seen in Opisthorchis. In 1926, Hung described a fluke from the cat which he called Parametorchis noveboracensis. In 1929, Price described P. intermedius and P. canadensis from the silver fox and mink respectively, from material collected by Law and Kennedy in Canada, and in 1934, Allen and Wardle described P. manitobensis from the dog. All of these are separable from each other on the basis of the specimens examined at the time of the various descriptions. However, when a large series is available and different hosts are infected experimentally from the same source, the differences disappear and all appear to be synonyms of Cobbold's Distoma conjunctum. All, however, had been placed in the genus Parametorchis. I have been unable to find any character that justifies the placing of Cobbold's species in any genus other than Metorchis. This leaves the genus Parametorchis with a single species, P. complexus, characterized by the union of the vitellaria. Meanwhile, in 1934, Hsu described from China, Metorchis felis, closely related to, but distinct from, M. albidus. Accordingly, the genus Metorchis has now three species in mammals, M. albidus from Europe, M. felis from China, and M. conjunctus from North America. All have very similar characteristics and all have definite geographical distributions. They can be distinguished moreover on morphological grounds as follows:
