通过透射电子显微镜研究了在法国捕获的黑线姬鼠 (Apododemus sylvaticus) 寄生虫 Collyricloides Massanae (Digenea: Collyriclidae) 的精子学特征。 C.masanae的成熟精子具有两个不同长度的轴丝，具有Trepaxonemata的9+“1”模式，两束平行的皮质微管，质膜的外部装饰，棘状体，一个线粒体，一个细胞核和糖原颗粒。对精子组织的分析强调了 C.massanae 的成熟精子与迄今为止研究的 Gorgoderoidea 物种（特别是属于 Dicrocoeliidae、Paragonimidae 和 Troglotrematidae 科）中报道的精子之间的一些差异。 C.massanae 中描述的超微结构标准，例如精子前肢和后肢的形态、“外部装饰+皮质微管”的关联、外部装饰的 2 型和脊柱状体，将使我们能够将 Collyriclidae 与 Microphalloidea 更接近。然而，需要进一步的超微结构和分子研究，特别是在未探索的类群中，以便完全解决 Collyriclidae 的系统发育位置。
The spermatological characteristics of Collyricloides massanae (Digenea: Collyriclidae), a parasite of Apodemus sylvaticus caught in France, were studied by means of transmission electron microscopy. The mature sperm of C. massanae presents two axonemes of different lengths with the 9 + “1” pattern of the Trepaxonemata, two bundles of parallel cortical microtubules, external ornamentation of the plasma membrane, spine-like bodies, one mitochondrion, a nucleus and granules of glycogen. An analysis of spermatological organisation emphasised some differences between the mature spermatozoon of C. massanae and those reported in the Gorgoderoidea species studied to date, specially belonging to the families Dicrocoeliidae, Paragonimidae and Troglotrematidae. The ultrastructural criteria described in C. massanae such as the morphology of both anterior and posterior spermatozoon extremities, the association “external ornamentation + cortical microtubules”, the type 2 of external ornamentation and the spine-like bodies would allow us to bring closer the Collyriclidae to Microphalloidea. However, further ultrastructural and molecular studies are needed particularly in the unexplored taxa in order to fully resolve the phylogenetic position of the Collyriclidae.
