摘要

Coitocaecum Nicoll属,1915年,是最具物种的digenean科的一部分,Opecoelidae Ozaki, 1925年,在全球淡水和海洋鱼类中都有发现。据报道,南非海鱼中有15种卵形纲,但仅有一种Coitocaecum在该地区被描述:Coitocaecum capense Bray, 1987。在对南非Saldanha Bay area、Cape Town harbour、Hermanus、Garden Route National Park Tsitsikamma section和Chintsa East的特有潮间带鱼类Clinus superciliosus (Linnaeus)的digenean进行了探索性研究,基于形态学和分子(28S rDNA、its1 - 58s - its2 rDNA和COI mtDNA)数据,共鉴定出3种不同的Coitocaecum。前面提到的C. capense, Coitocaecum brayi sp. n.和第三个未命名的物种。我们提供了来自南非的Coitocaecum物种的第一个分子特征,并附有详细的形态学描述。这项研究说明了综合分类方法的重要性,特别是在研究具有相似形态的物种时。这些发现进一步强调了缺乏关于南非海洋鱼类吸虫的真正多样性和分子数据的信息,为未来的探索性分类研究创造了巨大的能力,并突出了利用潮间带进行此类研究。

Molecular characterisation of three species of Coitocaecum (Digenea: Opecoelidae) infecting Clinus superciliosus (Clinidae) in South Africa, with description of Coitocaecum brayi sp. n.

The genus Coitocaecum Nicoll, 1915 is part of the most speciose digenean family, the Opecoelidae Ozaki, 1925, which is found globally in both freshwater and marine fishes. Fifteen opecoelid species have been reported from marine fishes in South Africa, yet only one species of Coitocaecum has been described from this region: Coitocaecum capense Bray, 1987. During an explorative study of the digeneans of the endemic, intertidal fish Clinus superciliosus (Linnaeus) from the Saldanha Bay area, Cape Town harbour, Hermanus, the Tsitsikamma section of the Garden Route National Park and Chintsa East in South Africa, a total of three distinct species of Coitocaecum were identified based on morphological and molecular (28S rDNA, ITS1-5.8S-ITS2 rDNA and COI mtDNA) data: the previously mentioned C. capense, Coitocaecum brayi sp. n. and a third, unnamed species. We provide the first molecular characterisation of species of Coitocaecum from South Africa, accompanied by detailed morphological descriptions. This study illustrates the importance of an integrated taxonomic approach, especially when studying species with similar morphology. These findings further emphasise the lack of information on the true diversity and molecular data for trematodes of marine fishes in South Africa, creating a great capacity for future explorative taxonomic studies and highlighting the use of intertidal areas for conducting such research.

期刊介绍: FOLIA PARASITOLOGICA, issued in online versions, is an international journal that covers the whole field of general, systematic, ecological and experimental parasitology. It publishes original research papers, research notes and review articles. Contributions from all branches of animal parasitology, such as morphology, taxonomy, biology, biochemistry, physiology, immunology, molecular biology and evolution of parasites, and host-parasite relationships, are eligible. Novelty and importance in the international (not local or regional) context are required. New geographical records of parasites, records of new hosts, regional parasite and/or host surveys (if they constitute the principal substance of manuscript), local/regional prevalence surveys of diseases, local/regional studies on epidemiology of well known diseases and of parasite impact on human/animal health, case reports, routine clinical studies and testing of established diagnostic or treatment procedures, will not be considered. One species description will also not be considered unless they include more general information, such as new diagnostic characters, host-parasite associations, phylogenetic implications, etc. Manuscripts found suitable on submission will be reviewed by at least two reviewers.
