Due to the presence of different parasite taxa and other disease-causing agents, all fish species are extremely prone to dangers. As a result, the current study focused on some of the monogenean parasites that infect one of the economically important fish species, the soldier bream , from the Red Sea coast of Jeddah, Saudi Arabia. Following that, thirty fish specimens were examined for monogenean parasites. The parasitic species were isolated and morphologically and molecularly studied. The presence of one monogenean species of (F: Ancyrocephalidae) infecting gills was observed in 50% of the investigated fish species. The ancyrocephalid species is characterized by having all generic features within the genus . It could be distinguished from other species within this genus by the male copulatory organ including a copulatory tube with no accessory piece and a haptor made up of two pairs of anchors, two bars, and seven pairs of marginal hooks. As ectoparasitic taxa of the investigated sparid fish, the current study of species constitutes the first report of this genus. A molecular phylogenetic analysis based on the partial gene region was analyzed to investigate the phylogenetic affinity of this parasite with the genus belonging to Ancyrocephalidae. This study considers the addition of a new genetic sequence for this parasite species.
由于存在不同的寄生虫类群和其他致病因子，所有鱼类都极易面临危险。因此，当前研究聚焦于一些单殖吸虫寄生虫，这些寄生虫感染了沙特阿拉伯吉达红海沿岸具有经济重要性的鱼类之一——军曹鲷。在此之后，对30个鱼类标本进行了单殖吸虫寄生虫检查。分离出寄生物种并进行了形态学和分子学研究。在50%的被调查鱼类物种中观察到一种单殖吸虫（F：锚首科）感染鳃部。该锚首科物种具有该属内所有的一般特征。它可以通过雄性交配器官与该属内其他物种区分开来，雄性交配器官包括一个没有附属片的交配管以及一个由两对锚、两条杆和七对边缘小钩组成的抱器。作为被调查鲷科鱼类的外寄生类群，对该物种的当前研究构成了该属的首次报告。基于部分基因区域进行了分子系统发育分析，以研究这种寄生虫与锚首科所属属的系统发育亲缘关系。本研究考虑为这种寄生虫物种添加一个新的基因序列。
