We report on a new amphibian species of the genus from Hainan Island, China, based on morphological and molecular analyses. The new species, , is diagnosed by a combination of the following morphological characters: medium-sized within genus (SVL 23.3-24.8 mm in males, =3; 27.7-30.1 mm in females, =2); dorsum bronze brown to reddish brown in life; dark brown spots and stripes on dorsum and flank absent; flanks largely pigmented with silver white; throat in adult males dark brown; undersides without dark patterns; outer metatarsal tubercle absent; supratympanic fold distinct; webbing between toes basal and poorly developed; tibiotarsal articulation adpressed limb reaching level of tympanum. The new species is divergent from all other congeners based on 16S rRNA gene sequences (3.0%-7.7%). Data on the natural history and male advertisement calls of the new species are provided. Following the IUCN Red List Categories and Criteria, we propose the new species to be listed as Vulnerable B1ab (iii).
我们基于形态学和分子分析，报道了来自中国海南岛的角蟾属的一个新种。该新种， ，通过以下形态特征组合来鉴别：属内中等大小（雄体 SVL 23.3-24.8 毫米， =3；雌体 27.7-30.1 毫米， =2）；生活时背部呈青铜棕色至红棕色；背面和侧部无深褐色斑点和条纹；侧面大部分呈银白色着色；成年雄体的喉部呈深褐色；底面无深色图案；无外跖突；鼓膜上方褶皱明显；趾间蹼基部和发育不良；胫跗关节紧贴肢体，达到鼓膜水平。新种基于 16S rRNA 基因序列（3.0%-7.7%）与所有其他近缘种明显不同。提供了该新种的自然历史和雄性广告叫声的数据。根据 IUCN 红色名录类别和标准，我们建议将新种列为易危 B1ab (iii)。
