摘要

Lake Tanganyika harbours the most diverse endemic cichlid fish assemblage of Africa, but its monogenean fish parasites have not been investigated. Here we report, for the first time, on the Gyrodactylus parasites in this hotspot of fish biodiversity. Haptor morphometrics and nuclear ribosomal DNA sequences revealed 3 new species on Zambian Simochromis diagramma: Gyrodactylus sturmbaueri n. sp., G. thysi n. sp. and G. zimbae n. sp. Their distinct morphology and strong genetic differentiation suggest that they belong to distant lineages within the genus Gyrodactylus, and phylogenetic reconstructions suggest affinities with other genera of gyrodactylids. Additional U-shaped haptoral plates in G. thysi n. sp. and a second large spine-like structure in the male copulatory organ of G. zimbae seem to represent new features for the genus. Such large diversity on a single host species can probably be explained by host-switching events during the course of evolution, in agreement with the generally accepted concept that ecological transfer is an important aspect of gyrodactylid speciation. Additional parasitological surveys on other host species, covering a broader phylogenetic and geographical range, should clarify the evolutionary history of Gyrodactylidae on cichlids in the African Great Lake and other parts of Africa.

Thysi N的额外U形触觉板。 SP。和G. Zimbae的雄性交叉组件中的第二种大脊椎结构似乎代表了该属的新特征。在单个宿主物种上的这种大多样性可能是通过在进化过程中的主机切换事件中解释，同时与生态转移是陀螺动态的一个重要方面的普遍接受的概念。其他宿主物种的额外寄生学调查，涵盖更广泛的系统发育和地理范围，应阐明非洲大湖和非洲其他地区的慈鲷葡萄球菌的进化史。
