The Dubois, 1992 exhibit a ubiquitous presence in East and Southeast Asia, spanning from Japan west to southern China and from northern Thailand to northern Vietnam and Laos in the south. The taxonomic categorisations pertaining to this genus continue to be a subject of debate, particularly with regard to those species that possess broad geographical distributions. In China, 18 species of Nidirana are currently recognised.
We describe a new species of this genus from south-western China. Mitochondrial 16S and COⅠ gene phylogenetic analyses support the new species as an independent clade nested within the . The new species is phylogenetically close to , with a genetic distance of 2.5% from its sister taxon. Morphologically, the new species can be distinguished from congeners by a combination of the following characteristics: males relatively small (SVL 41.8-43.3 mm); lateroventral grooves present on both fingers and toes; relative finger length Ⅱ < Ⅰ < Ⅳ < Ⅲ; tibio-tarsal articulation reaching to the level of the eye or nostril; a pair of external subgular vocal sacs in males; one single nuptial pad on the dorsal surface of the base of the first finger in males during the breeding season; webbing formula I 1/2 - 1 II 1/2 - 2 III 1 - 2½ IV 2 - 1V.
1992年的杜布瓦氏蛙在东亚和东南亚广泛分布，西起日本，东至中国南部，南至泰国北部、越南北部和老挝。该属的分类一直存在争议，特别是对于那些分布广泛的物种。在中国，目前已确认有18种姬蛙属物种。
我们描述了一种来自中国西南部的该属新物种。线粒体16S和COⅠ基因系统发育分析支持该新物种为嵌套在……内的一个独立分支。该新物种在系统发育上与……接近，与其姐妹分类单元的遗传距离为2.5%。在形态上，该新物种可通过以下特征组合与同属其他物种区分开来：雄性相对较小（体长41.8 - 43.3毫米）；手指和脚趾上均有外侧腹沟；相对指长Ⅱ < Ⅰ < Ⅳ < Ⅲ；胫跗关节达眼部或鼻孔水平；雄性有一对外部喉下声囊；繁殖季节雄性第一指基部背面有一个单一的婚垫；蹼式为Ⅰ 1/2 - 1 Ⅱ 1/2 - 2 Ⅲ 1 - 2½ Ⅳ 2 - 1Ⅴ 。
