A new species in the dicroglossid genus Limnonectes known only from Ha Giang province, Vietnam is described. Analysis of DNA sequence data from the mitochondrial 12S and 16S gene regions places the species within the Limnonectes kuhlii Complex and demonstrates it to be the sister taxon to an Indochinese clade containing L. isanensis, L. jarujini, L. megastomias, and L. taylori. The new species occurs in syntopy with L. bannaensis. Both molecular and morphological data support the recognition of this lineage as a new species. Notably, the relatively diminutive size of this species distinguishes Limnonectes nguyenorum sp. nov. from all other members of the L. kuhlii Complex.
描述了仅发现于越南河江省的叉舌蛙属（Limnonectes）新物种。对线粒体12S和16S基因区域的DNA序列数据进行分析，将该物种置于库氏叉舌蛙（Limnonectes kuhlii）复合体内，并证明它是包含伊山叉舌蛙（L. isanensis）、加鲁叉舌蛙（L. jarujini）、巨口叉舌蛙（L. megastomias）和泰勒叉舌蛙（L. taylori）的印度支那分支的姐妹分类单元。新物种与版纳叉舌蛙（L. bannaensis）同域分布。分子和形态学数据均支持将这一分支识别为新物种。值得注意的是，该物种相对较小的体型使其区别于库氏叉舌蛙复合体的所有其他成员，即阮氏叉舌蛙（Limnonectes nguyenorum sp. nov.）。
