We describe a new species of Phrynobatrachus from the eastern part of the Upper Guinea forest region, Ghana, West Africa. Morphologically, the new species can be distinguished from all of its congeners by the combination of a slender body, short and pointed snout, a relatively warty dorsum, a black-spotted throat in both sexes, a gular flap in males, a dark spotted chest, a white-greyish venter with occasional blackish spots, rudimentary pedal webbing, none to slightly dilated finger tips and strongly delated toe tips, presence of both inner and outer metatarsal tubercles and absence of a dark face mask, eyelid tubercles and longer dorsal ridges. We collected mitochondrial DNA (mtDNA) sequence data from the 16S rRNA gene to measure the genetic diversity of the new species, and to estimate phylogenetic relationships. The new species is a distinct and monophyletic evolutionary lineage most closely related to Phrynobatrachus gutturosus, P. fraterculus and P. maculiventris. The discovery of this new species highlights that the biodiversity of West African forests is still incompletely known and that the few remaining forests need urgent protection.
我们描述了一种来自西非加纳上几内亚森林地区东部的新种姬蛙。从形态学上看，该新物种可通过以下特征组合与所有同属物种区分开来：身体细长、吻短且尖、背部相对多疣、两性喉部均有黑斑、雄性有喉褶、胸部有黑斑、腹部灰白色且偶尔有黑斑、蹼发育不全、指尖无膨大或稍有膨大、趾尖强烈膨大、有内跖突和外跖突、无深色面罩、眼睑瘤和较长的背嵴。我们从16S rRNA基因收集了线粒体DNA（mtDNA）序列数据，以测量新物种的遗传多样性，并估计系统发育关系。该新物种是一个独特的单系进化谱系，与喉鸣姬蛙、兄弟姬蛙和斑腹姬蛙关系最为密切。这一新物种的发现突出表明，西非森林的生物多样性仍未完全为人所知，剩余的少数森林亟需保护。
