Among New World direct-developing frogs belonging to the clade Brachycephaloidea (= Terraranae), there are several genera with uncertain phylogenetic placements. One notable example is the genus Niceforonia Goin Cochran 1963, which includes three species that are endemic to Colombia. Three specimens of the species Niceforonia nana were collected and for the first time the genus is included in a molecular phylogenetic analysis of mitochondrial (mtDNA; 12S and 16S) and nuclear (nucDNA; TYR and RAG1) markers. Molecular phylogenetic inference based on concatenated and separate mtDNA and nucDNA analyses recovered Niceforonia nana nested within Hypodactylus Hedges et al. 2008, rendering the latter genus paraphyletic. Consequently, herein we place the genus Hypodactylus in the synonymy of Niceforonia to resolve the paraphyly and place Niceforonia in the subfamily Hypodactylinae. Based on our revised concept of the genus Niceforonia we conducted preliminary morphological comparisons using specimens and literature descriptions. Finally, Nicefornia nana is quite divergent from other species of Niceforonia (uncorrected genetic distances of ca. 10% 16S and 7% TYR) suggesting that further taxonomic revision may be warranted.
在新世界直接发育的属于短头蛙超科（= 陆栖蛙类）的蛙类中，有几个属的系统发育位置不确定。一个显著的例子是1963年戈因和科克伦命名的尼氏蛙属，该属包括三种哥伦比亚特有物种。采集了尼氏矮蛙的三个标本，并首次将该属纳入线粒体（mtDNA；12S和16S）和核（nucDNA；TYR和RAG1）标记的分子系统发育分析。基于串联和单独的mtDNA和nucDNA分析的分子系统发育推断发现，尼氏矮蛙嵌套在2008年赫奇斯等人命名的 Hypodactylus 属内，这使得后者成为并系群。因此，我们在此将 Hypodactylus 属归入尼氏蛙属的同义词，以解决并系问题，并将尼氏蛙属置于 Hypodactylinae 亚科中。基于我们对尼氏蛙属的修订概念，我们使用标本和文献描述进行了初步的形态比较。最后，尼氏矮蛙与尼氏蛙属的其他物种有很大差异（16S的未校正遗传距离约为10%，TYR的约为7%），这表明可能需要进一步的分类修订。
