Abstract

This study focuses on the opecoelid genus Podocotyle, particularly the species in the northern European seas (White, Barents and Pechora), with additional data from few isolates from the Far East. The research combines molecular analyses (28S, 5.8S+ITS2 rDNA, and cox1 mtDNA) and morphological examinations. Molecular analyses suggested that there are most likely four species of Podocotyle in the northern European seas and three more in the Far East. Morphological redescriptions are provided for three northern European species: P. atomon, P. reflexa, and P. odhneri, with the latter recognized as a valid species. The study also verified the life cycle of P. atomon and identified Lacuna vincta (Littorinidae) as the first intermediate host for P. reflexa. In the Sea of Okhotsk, L. turrita is the first intermediate host for two apparently undescribed Podocotyle species. The results also highlight the morphological variability of P. atomon, emphasizing the need for an integrative approach in the taxonomy and biodiversity studies.

徘徊在分类学雷区：Podocotyle物种复合体（Digenea: Opecoelidae）。

本研究重点关注 Podocotyle 藻属，尤其是北欧海域（白海、巴伦支海和佩科拉海）的物种，以及来自远东的少量分离物。研究结合了分子分析（28S、5.8S+ITS2 rDNA 和 cox1 mtDNA）和形态学检查。分子分析表明，北欧海域很可能有 4 个 Podocotyle 物种，远东还有 3 个。对北欧的三个物种进行了形态学重新描述：P.atomon、P.reflexa 和 P.odhneri，其中后者被认定为有效物种。该研究还验证了 P. atomon 的生命周期，并确定 Lacuna vincta（Littorinidae）为 P. reflexa 的第一中间宿主。在鄂霍次克海，L. turrita是两个显然未被描述过的Podocotyle物种的第一中间宿主。研究结果还突显了P. atomon的形态变异性，强调了在分类学和生物多样性研究中采用综合方法的必要性。

期刊介绍： Systematic Parasitology publishes papers on the systematics, taxonomy and nomenclature of the following groups: Nematoda (including plant-parasitic), Monogenea, Digenea, Cestoda, Acanthocephala, Aspidogastrea, Cestodaria, Arthropoda (parasitic copepods, hymenopterans, mites, ticks, etc.), Protozoa (parasitic groups), and parasitic genera in other groups, such as Mollusca, Turbelleria, etc. Systematic Parasitology publishes fully illustrated research papers, brief communications, and fully illustrated major revisions. In order to maintain high standards, all contributors describing new taxa are asked to state clearly where the holotype is deposited and to make paratypes available for examination by the referees. It is recognized that, in some cases, this may cause problems for the authors, but it is hoped that by adhering to this rule authors may be protected against rapid synonymy of their taxa, and the types will be preserved for posterity.
