To date, 41 species of have been described from Africa. However, none of these have been reported in Morocco. After identifying and examining 738 cyprinid host specimens, 26 specimens belonging to were found to parasitize the gills of nine species of , , and . The current study provides new information about the presence of a new parasitic species in Morocco, the first to be characterized on a species level in the Maghreb region. It describes in detail 12 specimens of isolated from the gills of (Pellegrin, 1919) and (Boulenger, 1905). Based on morphoanatomical observations, the characterization of the specimens collected indicates a species of that is new to science, described here as n. sp. The new species is different from previously described gyrodactylids infecting African cyprinid hosts because it has a longer hamulus total length, a longer hamulus root, a downward projecting toe of the marginal hook, and a trapezium-shaped ventral bar membrane with a slightly striated median portion and small rounded anterolateral processes. This study increases the total number of spp. found in African cyprinids to four.
迄今为止，已从非洲描述了41种[该寄生虫名称未给出]。然而，摩洛哥尚未报告过其中任何一种。在鉴定和检查了738个鲤科宿主标本后，发现属于[该寄生虫名称未给出]的26个标本寄生在9种[宿主鱼类名称未给出]、[宿主鱼类名称未给出]和[宿主鱼类名称未给出]的鳃上。本研究提供了关于摩洛哥存在一种新寄生虫物种的新信息，这是在马格里布地区首个在物种水平上进行特征描述的物种。它详细描述了从[佩勒格林，1919年]和[布伦格，1905年]的鳃中分离出的12个[该寄生虫名称未给出]标本。基于形态解剖学观察，所收集标本的特征表明是一种科学上新发现的[该寄生虫名称未给出]物种，在此描述为[新物种名称未给出]新种。该新物种与先前描述的感染非洲鲤科宿主的三代虫不同，因为它的小钩总长度更长、小钩根部更长、边缘小钩的趾向下突出，以及腹杆膜呈梯形，中间部分有轻微条纹且前侧有小圆形突起。本研究将在非洲鲤科鱼类中发现的[该寄生虫名称未给出]物种总数增加到了4种。
