A new species, Gracixalus jinggangensis sp. nov., is described based on a series of specimens collected from Mount Jinggang, Jiangxi Province, southeastern China. The new species is distinguished from all other known congeners by the following combination of morphological characters: relatively small body size, SVL 27.9-33.8 mm in nine males and 31.6 mm in a single female; upper eyelid and dorsum lacking spines; skin of dorsal and lateral surface of head, body and limbs rough with sparsely scattered with tubercles; ventral skin granular; tibiotarsal projection absent; finger webbing rudimentary; toes with moderately developed webbing; brown to beige above in life, with an inverse Y-shaped dark brown marking extending from the interorbital region to the middle of dorsum; males with a single, subgular vocal sac, barely visible nuptial pads with minute granules on the dorsal surface of the bases of first and second fingers. The new species is also genetically divergent from all other Gracixalus for which comparable 16S rRNA gene sequences are available. The discovery of Gracixalus jinggangensis sp. nov. represents the twelfth known species in the genus.
基于从中国东南部江西省井冈山采集的一系列标本，描述了一个新物种——井冈山姬蛙（Gracixalus jinggangensis sp. nov.）。该新物种与所有其他已知同属物种的区别在于以下形态特征组合：体型相对较小，9只雄性个体的体长（SVL）为27.9 - 33.8毫米，1只雌性个体的体长为31.6毫米；上眼睑和背部无棘；头部、身体和四肢背面及侧面的皮肤粗糙，散布着稀疏的瘤粒；腹部皮肤呈颗粒状；无胫跗突；指蹼不发达；趾间有适度发达的蹼；活体时背部呈棕色至米色，有一个倒Y形深棕色斑纹从眶间区域延伸至背部中央；雄性有一个单一的、位于喉下部的声囊，第一和第二指基部背面有几乎不可见的婚垫，上面有微小颗粒。该新物种在基因上也与所有其他有可比16S rRNA基因序列的姬蛙属物种不同。井冈山姬蛙的发现代表了该属已知的第12个物种。
