A new species of Limnonectes is described from northeastern Vietnam 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: Large size (SVL 50.1-68.9 in males, 45.5-63.0 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 0.16 in males, 0.15 in females); tympanum distinct (TD/ED 0.63 in males, 0.60 in females); dorsal surface of head, body and flanks with flattened tubercles; dorsal surface of tibia possessing small tubercles; supratympanic fold present; dorsolateral fold absent; webbing formula I0-0II0-1/3III0-1/3IV1/2-0V; in life, dorsum yellowish brown with a dark brown marking; throat and chest white with dark brown marking; ventral surface of fore and hind limbs as well as belly white. In phylogenetic analyses, the new species is placed as the sister taxon to Limnonectes fujianensis with strong statistical support in all analyses.
基于形态和分子差异，在越南北部描述了一种新的林蛙属物种。在形态上，新物种与同属其他物种的区别在于具有以下综合诊断特征：体型大（雄性体长50.1 - 68.9毫米，雌性45.5 - 63.0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0.16，雌性0.15）；鼓膜明显（雄性鼓膜直径/眼径0.63，雌性0.60）；头部、身体和体侧背面有扁平瘤；胫部背面有小瘤；有颞褶；无背外侧褶；蹼式为I0 - 0II0 - 1/3III0 - 1/3IV1/2 - 0V；活体时，背部黄棕色有深棕色斑纹；咽喉和胸部白色有深棕色斑纹；前肢和后肢腹面以及腹部白色。在系统发育分析中，新物种在所有分析中均获得有力统计支持，被置于福建林蛙的姐妹分类单元位置。
