虽然坦噶尼喀湖拥有最多样化的特有慈鲷鱼组合，但其单殖寄生虫动物群几乎没有记录。慈鲷族Tropheini由于其在Haplochromini s.l.中的系统位置而引起了极大的兴趣。在营养形态、繁殖行为和种群结构上的多样性。它有可能成为多种单殖吸虫动物群的宿主。在这里，我们描述了第一个Cichlidogyrus spp.：斯氏丽回鱼，爱尔兰丽回虫，新种和吉氏丽回鱼Cichlidogyrus gistelincki sp. n.三个主机种，Limnotilapia dardennii，Ctenochromis horei和Gnathochromis pfefferi，都感染了一个单一的独特的Cichlidogyrus sp.的新物种的生殖器和haptoral结构表明了密切的关系，这可能反映了Tropheini内的主机之间的密切关系。根据haptoral配置，新物种属于一个形态组内的属包含寄生虫的西非慈鲷和Haplochromini，因此，不代表一个新的组织的附件器官（最近已被描述的同源物感染的ectodine慈鲷Ophthalmotilapia）。
Although Lake Tanganyika hosts the most diverse endemic cichlid fish assemblage, its monogenean parasite fauna has hardly been documented. The cichlid tribe Tropheini has generated great interest because of its systematic position within the Haplochromini s.l. and its diversity in trophic morphology, reproductive behaviour and population structure. It has the potential to host a diverse Monogenea fauna. Here, we describe the first Cichlidogyrus spp.: Cichlidogyrus steenbergei sp. n., Cichlidogyrus irenae sp. n. and Cichlidogyrus gistelincki sp. n. The three host species, Limnotilapia dardennii, Ctenochromis horei and Gnathochromis pfefferi, are all infected by a single unique Cichlidogyrus sp. The genital and haptoral structure of the new species suggests a close relationship, which might mirror the close affinities between the hosts within the Tropheini. Based on haptoral configuration, the new species belong to a morphological group within the genus containing parasites both of West African cichlids and of Haplochromini, and hence, do not represent a new organisation of the attachment organ (as has recently been described of congeners infecting the ectodine cichlid Ophthalmotilapia).
