A new species of the genus Microhyla is described from Jamun Khadi, Jhapa district of eastern Nepal, based on molecular and morphological comparisons. This species is the sister taxon of Microhyla ornata and can be distinguished by a unique vocalization, morphology and molecular phylogeny. The uncorrected genetic divergences based on rRNA gene between the new species and its closest congeners, M. nilphamariensis, M. ornata and M. rubra were 5.34%, 6.67%, and 8.31%, respectively. The new species, Microhyla taraiensis sp. nov., is distinguished from each other of Microhyla by a combination of the following morphological characters: (1) relatively larger body size (SVL ranges 19.9-20.3 mm, n = 4 in the males and 22.1-24.9 mm, n = 3 in the females); (2) dorsal surface of head and body with light red dots; (3) toes webbing poorly developed or absent; (4) a large round inner metacarpal tubercle; and an (5) elongated outer metacarpal tubercle. In addition, our study also provides a new record of Microhyla nilphamariensis from Nepal.
基于分子和形态学比较，在尼泊尔东部贾帕县的Jamun Khadi描述了姬蛙属的一个新物种。该物种是饰纹姬蛙的姐妹分类单元，可通过独特的鸣声、形态和分子系统发育来区分。新物种与其最接近的同属物种尼尔吉里姬蛙、饰纹姬蛙和红斑姬蛙基于rRNA基因的未校正遗传差异分别为5.34%、6.67%和8.31%。新物种尼泊尔姬蛙（Microhyla taraiensis sp. nov.）通过以下形态特征的组合与其他姬蛙物种相区分：（1）体型相对较大（雄性体长范围为19.9 - 20.3毫米，n = 4；雌性体长范围为22.1 - 24.9毫米，n = 3）；（2）头部和身体背面有浅红色斑点；（3）趾间蹼发育不良或无蹼；（4）一个大的圆形内掌突；以及（5）一个细长的外掌突。此外，我们的研究还提供了尼尔吉里姬蛙在尼泊尔的新记录。
