Madtom catfishes of the genus Noturus are a well-known component of the North American ichthyofauna. Original nucleotide sequence data were collected from mitochondrial (cytochrome b) and nuclear (recombination activating gene 2) genes and used to estimate genetic variation and infer phylogenetic relationships among and within species of Noturus. Mitochondrial sequences were variable among species and several species were found to contain considerable genetic diversity. Relationships among members of the subgenus Rabida were resolved and in many cases well supported. Relationships among members of the subgenus Schilbeodes were poorly resolved. Previous phylogenetic hypotheses and the traditional classification (except the furiosus species group) were rejected in their explicit form according to the Kishino-Hasegawa and Shimodaira-Hasegawa tests of tree score difference.
诺图鲁斯属的疯鲶鱼是北美鱼类区系中广为人知的组成部分。从线粒体（细胞色素b）和核（重组激活基因2）基因中收集了原始核苷酸序列数据，并用于估计遗传变异以及推断诺图鲁斯属物种之间和物种内部的系统发育关系。线粒体序列在物种间存在差异，并且发现几个物种含有相当大的遗传多样性。拉比达亚属成员之间的关系得到了解决，并且在许多情况下得到了有力支持。希勒波德斯亚属成员之间的关系解析得很差。根据树得分差异的木村-长谷川检验和岛田-长谷川检验，先前的系统发育假设和传统分类（除了弗留奥苏斯物种组）的明确形式被否定。
