The genus Clinostomum Leidy, 1856 (Digenea: Clinostomidae) has been reported in all ecozones of the world and a clear separation between the species of the 'Old World' and 'New World' has been recognized based on molecular studies. Recent works on Afrotropical species include redescriptions of C. cutaneum and C. phalacrocoracis, while C. tilapiae has yet to be studied using modern taxonomic approaches. In the present research, morphological redescription of C. tilapiae metacercariae from a new host, Synodontis batensoda sampled at Anambra River Basin, Nigeria, together with molecular analysis of nuclear internal transcribed spacer rDNA and cytochrome c oxidase 1 mtDNA are reported. We also provide morphological and molecular data from four further putative species of Clinostomum (morphotypes 1-4) from different areas of Africa, as well as the first report of C. phalacrocoracis in South Africa.
1856年命名的斜口吸虫属（复殖吸虫纲：斜口吸虫科）在世界所有生态区均有报道，基于分子研究已明确区分出“旧世界”和“新世界”的物种。近期关于非洲热带地区物种的研究包括对皮肤斜口吸虫和鸬鹚斜口吸虫的重新描述，而罗非鱼斜口吸虫尚未采用现代分类学方法进行研究。在本研究中，报告了从尼日利亚阿南布拉河流域采集的新宿主巴氏歧须鮠体内罗非鱼斜口吸虫尾蚴的形态重新描述，以及核糖体DNA内部转录间隔区和细胞色素c氧化酶1线粒体DNA的分子分析。我们还提供了来自非洲不同地区另外四种疑似斜口吸虫属物种（形态型1 - 4）的形态和分子数据，以及南非鸬鹚斜口吸虫的首次报道。
