Abstract

Purpose

A new monogenean Microcotyle justinei n. sp. (Monogenea: Microcotylidae) is described based on specimens found on the gill filaments of the cardinal fish Apogon imberbis (Apogonidae) off the Algerian coast of the Western Mediterranean.

Methods

Monogeneans were examined, measured and drawn for a comparative morphological study with other species of Microcotyle and characterised molecularly using a partial fragment of the mitochondrial cytochrome c oxidase subunit 1 (cox1) gene. The identification of fish was confirmed by molecular barcoding using the cox1 gene.

Results

The new species is distinguished from all other species of the genus by a combination of features, such as the number and size of the clamps, the shape and size of the genital atrium and the number of testes. The molecular analysis of the cox1 gene sequences showed that interspecific differences between Microcotyle justinei n. sp. and published sequences of Microcotyle spp. was greater than 8.8%, strongly suggesting that the new species is distinct from other congeners with sequences available on GenBank.

Conclusion

The morphological and molecular analyses support the status of M. justinei as a new species. The present finding extends the list of Microcotyle spp. to 72.

来自地中海西部阿尔及利亚海岸的Cardinal Fish Apogon imberbis（Teleostei：Apogonidae）鳃的微型justinei n.sp.（单基因门：微型科）。

目的：根据在地中海西部阿尔及利亚海岸的主要鱼类Apogon imberbis（Apogonidae）的鳃丝上发现的标本，描述了一种新的单基因微体justinei n.sp.（单基因亚：微体科），测量和绘制用于与Microstyle的其他物种进行比较形态学研究，并使用线粒体细胞色素c氧化酶亚基1（cox1）基因的部分片段进行分子表征。通过使用cox1基因的分子条形码确认了鱼类的鉴定。结果：该新种通过夹子的数量和大小、生殖心房的形状和大小以及睾丸的数量等特征与该属所有其他物种相区别。对cox1基因序列的分子分析表明，微小型justinei n.sp.与已发表的微小型justinei n.sp的种间差异大于8.8%，这有力地表明该新种与GenBank上已有序列的其他同源物不同。结论：形态学和分子分析支持M.justinei作为一个新种的地位。目前的发现将Microstyle spp.的列表扩展到72。

期刊介绍： Acta Parasitologica is an international journal covering the latest advances in the subject. Acta Parasitologica publishes original papers on all aspects of parasitology and host-parasite relationships, including the latest discoveries in biochemical and molecular biology of parasites, their physiology, morphology, taxonomy and ecology, as well as original research papers on immunology, pathology, and epidemiology of parasitic diseases in the context of medical, veterinary and biological sciences. The journal also publishes short research notes, invited review articles, book reviews. The journal was founded in 1953 as "Acta Parasitologica Polonica" by the Polish Parasitological Society and since 1954 has been published by W. Stefanski Institute of Parasitology of the Polish Academy of Sciences in Warsaw. Since 1992 in has appeared as Acta Parasitologica in four issues per year.
