Individual gene trees of Synodontis relationships inferred from Bayesian analyses for a) mitochondrial Cytochrome oxidase I (COI), b) mitochondrial Cytochrome b (Cyt b + tRNA-pro), c) nuclear S7 ribosomal protein intron 1 and 2 (S7) and d) nuclear recombination activating gene (Rag 2). Taxa are colour coded according to the biogeographical clade they nest within based on Figure 2: purple, Congo Basin; blue, East Africa; green, West Africa (light green WA NS; dark green WA LGF). BPP values include black circle: >85%; black square 70-84%.

本研究基于贝叶斯分析构建了歧须鮠属（Synodontis）亲缘关系的单基因树，具体包括：a) 线粒体细胞色素氧化酶亚基I（COI）；b) 线粒体细胞色素b（Cyt b + tRNA-pro）；c) 核S7核糖体蛋白内含子1与2（S7）；d) 核重组激活基因2（Rag 2）。基于图2，所有分类群按其所隶属的生物地理支系进行颜色编码：紫色代表刚果盆地支系；蓝色代表东非支系；绿色代表西非支系（浅绿色为西非NS类群，深绿色为西非LGF类群）。贝叶斯后验概率（BPP）值的标注规则为：黑色圆点表示支持率大于85%；黑色方块表示支持率介于70%至84%之间。
