A new species of Limnonectes from central Vietnam is described based on morphological and molecular differences. Morphologically, the new species is distinguishable from its congeners on the basis of a combination of the following diagnostic characters: SVL 47.5-60.9 in males, 42.3-51.1 mm in females; males with moderately enlarged head (HL/SVL 0.48), head longer than wide; vomerine teeth present; external vocal sacs absent; rostral length short (RL/SVL 0.14 in males, 0.15 in females); tympanum invisible; dorsal surface of head, body, and flanks smooth; dorsal surface of tibia and foot distinctly tuberculate, covered with moderately dense, small, low tubercles; supratympanic fold present; dorsolateral fold absent; toes webbed to posterior of terminal phalanx; in life, dorsum with light yellowish brown markings, throat and chest white with brown markings, and ventral surface of abdomen white or white with brown markings. In phylogenetic analyses, the new species is the sister taxon to an undescribed species from Cambodia.
基于形态学和分子差异，描述了一种来自越南中部的新林蛙物种。在形态上，新物种与同属其他物种的区别在于以下诊断特征的组合：雄性体长47.5 - 60.9毫米，雌性体长42.3 - 51.1毫米；雄性头部适度增大（头长/体长0.48），头长大于宽；有犁骨齿；无外声囊；吻长较短（雄性吻长/体长0.14，雌性0.15）；鼓膜不可见；头部、身体和体侧背面光滑；胫部和足部背面明显有瘤，覆盖着适度密集的小而低的瘤；有颞褶；无背外侧褶；趾蹼至末节指骨后部；活体时，背部有浅黄褐色斑纹，喉部和胸部白色有褐色斑纹，腹部腹面白色或白色有褐色斑纹。在系统发育分析中，新物种是来自柬埔寨的一个未描述物种的姐妹分类单元。
