Narrow-mouthed frogs (Anura: Microhylidae) are globally distributed and molecular data suggest the rapid evolution of multiple subfamilies shortly after their origin. Despite recent progress, several subfamilial relationships remain unexplored using phylogenomic data. We analysed 1,796 nuclear ultraconserved elements, a total matrix of 400,664 nucleotides, from representatives of most microhylid subfamilies. Summary method species-tree and maximum likelihood analyses unambiguously supported Hoplophryninae as the earliest diverging microhylid and confirm Chaperininae as a junior synonym of Microhylinae. Given the emerging consensus that subfamilies from mainland Africa diverged early, microhylids have likely occupied the continent for more than 66 million years.
窄口蛙（无尾目：微褶蛙科）分布广泛，分子数据表明，它们在起源后不久就快速进化出了多个亚科。尽管最近取得了一些进展，但仍有几个亚科关系尚未利用系统基因组学数据进行研究。我们分析了大多数微褶蛙科代表的 1796 个核超保守元件，总矩阵为 400664 个核苷酸。摘要方法种系树和最大似然分析明确支持 Hoplophryninae 是最早分化的微褶蛙科，同时确认 Chaperininae 是 Microhylinae 的一个次同义词。鉴于非洲大陆的亚科很早就开始分化的共识，微褶蛙科可能已经在这个大陆上生活了超过 6600 万年。
