Abstract

The distribution of ciliated cells and the oncomiracidium chaetotaxy in Ancyrocephalus paradoxus Creplin, 1839 (Ancyrocephalidae) parasite of Sander lucioperca (Teleostean, Percidae) are described for the first time as well as the larval ciliated cells in Dactylogyrus extensus (Dactylogyridae) parasite of Cyprinus carpio. Also is given a description of the larval haptorial armature of Ancyrocephalus paradoxus which shows some original features in our region. The ciliated cell pattern and chaetotaxy are compared among Ancyrocephalus paradoxus (Ancyrocephalidae) Ergenstrema mugilis (Ancyrocephalidae) Dactylogyrus extensus (Dactylogyridae) Tetraonchus menenteron (Tetraonchidae) and Euzetrema knopffleri the systematic position of which is still to be defined. As a result it appears that an unitary pattern occurs in the ciliated cell arrangement and chaetotaxy in the larvae of Ancyrocephalus paradoxus, Ergenstrema mugilis and Dactylogyrus extensus. Yet they are easy to distinguish. Tetraonchus monenteron reveals some affinities with these Dactylogyroïdea but further investigations have to be undertaken again while Euzetrema knoepffleri proves to be very different. In the armature of the larval haptor of Ancyrocephalus paradoxus intraspecific variations appear which seem to be of a biogeographic order. Also the same variations are reported in the larvae of Diplectanum aequans.

摘要

首次描述了鲈塘鳢（硬骨鱼纲，鲈科）的寄生吸虫——奇异锚首吸虫（Ancyrocephalus paradoxus Creplin，1839年）（锚首科）的纤毛细胞分布和幼虫纤毛排列，以及鲤（鲤科）的寄生吸虫——伸展指环虫（Dactylogyrus extensus）（指环虫科）的幼虫纤毛细胞。还对奇异锚首吸虫幼虫的吸附器结构进行了描述，该结构在我们的研究区域呈现出一些独特特征。对奇异锚首吸虫（锚首科）、鳗鲡锚首吸虫（Ergenstrema mugilis）（锚首科）、伸展指环虫（指环虫科）、肠四联吸虫（Tetraonchus menenteron）（四联科）和克氏艾氏吸虫（Euzetrema knopffleri）（其系统位置仍有待确定）的纤毛细胞模式和纤毛排列进行了比较。结果表明，奇异锚首吸虫、鳗鲡锚首吸虫和伸展指环虫的幼虫在纤毛细胞排列和纤毛排列上呈现出统一模式。然而，它们很容易区分。肠四联吸虫与这些指环虫类显示出一些亲缘关系，但仍需进一步研究，而克氏艾氏吸虫则证明有很大不同。在奇异锚首吸虫幼虫吸附器的结构中出现了种内变异，这些变异似乎具有生物地理学特征。在均等复殖吸虫（Diplectanum aequans）的幼虫中也报道了同样的变异。
