用透射电镜观察了鼠冠口线虫和细冠口线虫的成熟精子。他们提出了几个超微结构的特点，以前在其他digeneans报告。它们的精子有两个不同长度的轴丝，呈9 +“1”型，四个附着带，两个线粒体（在S.细胞核、两束平行的皮层微管、质膜外膜、棘状体和糖原颗粒。成熟精子与成熟精子的主要区别在于精子的形态结构不同。murifenic和S. tenuis是皮质微管的最大数量，精子前端和前囊的形态。这项研究是第一个关于家庭Acanthocolpidae的成员。主要的超微结构特征包括精子前后端的形态、前外侧电子致密物质、外展结构、棘状体、线粒体的数量和形态。此外，所有这些超微结构特征的系统发育的意义进行了讨论，并比较分子结果，以突出复杂的关系，在Digenea。
The mature spermatozoa of Stephanostomum murielae and Stephanostomoides tenuis are described by transmission electron microscopy. They present several ultrastructural features previously reported in other digeneans. Their spermatozoa possess two axonemes of different length showing the 9 + ‘1’ trepaxonematan pattern, four attachment zones, two mitochondria (with an anterior moniliform one in S. murielae), a nucleus, two bundles of parallel cortical microtubules, external ornamentation of the plasma membrane, spine-like bodies and granules of glycogen. The main differences between the mature spermatozoon of S. murielae and S. tenuis are the maximum number of cortical microtubules, the morphology of the anterior spermatozoon extremity and the anterior mitochondrion. This study is the first concerning members of the family Acanthocolpidae. The main ultrastructural characteristics discussed are the morphology of the anterior and posterior spermatozoon extremities, antero-lateral electron dense material, external ornamentations, spine-like bodies and number and morphology of mitochondria. In addition, the phylogenetic significance of all these ultrastructural features is discussed and compared to molecular results in order to highlight the complex relationships in the Digenea.
