Abstract：
To date, 41 species of Gyrodactylus 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 Gyrodactylus were found to parasitize the gills of nine species of Luciobarbus, Carasobarbus, and Pterocapoeta. 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 Gyrodactylus isolated from the gills of Luciobarbus pallaryi (Pellegrin, 1919) and Luciobarbus ksibi (Boulenger, 1905). Based on morphoanatomical observations, the characterization of the specimens collected indicates a species of Gyrodactylus that is new to science, described here as Gyrodactylus nyingiae 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 Gyrodactylus spp. found in African cyprinids to four.
摘要：
迄今为止,已从非洲描述了41种Gyrodactylus。然而,这些都没有在摩洛哥报告。在鉴定和检查了738个鲤鱼宿主标本后，发现26个属于Gyrodactylus的标本寄生了9种Luciobarbus的g，Carasobarbus,还有Pterocapoeta.当前的研究提供了有关摩洛哥新寄生物种存在的新信息，第一个在马格里布地区的物种水平上进行表征。它详细描述了从Luciobarbuspallaryi（Pellegrin，1919年）和Luciobarbusksibi（Boulenger，1905).根据形态解剖学观察,采集的标本的特征表明了一种新的科学陀螺，这里描述为gyrodactylusnyingiaen.sp.新物种与先前描述的感染非洲鲤科动物宿主的回旋手叉不同，因为它的整体长度更长，一个较长的树根，边缘钩子向下突出的脚趾，和一个梯形的腹侧条膜，中间部分有轻微的条纹和小的圆形前外侧突。这项研究增加了Gyrodactylusspp的总数。在非洲赛普尼德中发现了四个。
