A new species of the genus Gracixalus is described from Nonggang National Nature Reserve, based on eleven specimens from evergreen karst forests in Sino-Vietnamese border region of southern China. The new species, Gracixalus nonggan-gensis sp. nov., is medium sized species of Gracixalus that can be distinguished from its congeners by a combination of the following characters: SVL ranging from 29.9-35.3 mm in males and 33.6-38.0 mm in females; vomerine teeth absent; distinct tympanum as wide as the disc of finger III; the lower part of the tympanum with many small tubercles; tibiotarsal articulation reaching the tip of the snout; dorsum smooth yellowish-olive in life with a wide, dark-green irregular mark; throat, chest and belly white with light grey-blue tint and brown marbling; broad, dark olive, transverse stripes on limbs; finger webbing absent, toes one-third webbed; male with internal subgular vocal sac. Based on a 16S ribosomal RNA mitochondrial gene fragment, G. nonggangensis sp. nov. forms a monophyletic group embedded within the genus Gracixalus.
基于采自中国南部中越边境地区常绿喀斯特森林的11个标本，在弄岗国家级自然保护区发现了棱皮树蛙属的一个新物种。新物种为弄岗棱皮树蛙（Gracixalus nonggangensis sp. nov.），是棱皮树蛙属的中等体型物种，可通过以下特征组合与同属其他物种区分开来：雄蛙体长29.9 - 35.3毫米，雌蛙体长33.6 - 38.0毫米；无犁骨齿；鼓膜明显，与第三指吸盘等宽；鼓膜下部有许多小瘤；胫跗关节达吻端；活体时背部光滑，呈黄橄榄色，有一条宽的深绿色不规则斑纹；咽喉部、胸部和腹部白色，有浅灰蓝色调及褐色云斑；四肢有宽的深橄榄色横纹；指间无蹼，趾间约三分之一蹼；雄蛙具内声囊。基于线粒体16S核糖体RNA基因片段，弄岗棱皮树蛙形成一个单系类群，嵌套在棱皮树蛙属内。
