Asian leaf-litter toads of the genus represent charismatic anuran diversification with 80 species, of which 25 are from China. Recent new discoveries suggest that the diversity of this genus is underestimated. Here, we describe a new species of , from the Basha Nature Reserve, Congjiang County, Guizhou Province, China. The new species is distinguished from its congeners by the following suite of morphological traits: small body size (SVL 22.9-25.6 mm in six adult males and 27.1 mm in one adult female); head longer than wide; dorsal skin slightly shagreened with small tubercles; creamy-white chest and belly with irregular black spots; distinct ventrolateral glands forming a white line; finger webbing and fringes absent; toe webbing rudimentary and lateral fringes narrow; iris bicolored with bright orange in upper half and silver in lower half; dorsal surface of tadpole head dark brown with small, brown, irregular spot, air sac-shaped bulges on both sides of body. The new species differs from all known congeners by an uncorrected -distance of >5.3% of the 16S rRNA gene fragment examined, and the phylogenetic analysis clusters the new species with and . At present, the new species is only known from a small range of montane evergreen secondary forests in Basha Nature Reserve approximately 900 m elevation. Its natural history and conservation status are discussed.
属的亚洲叶栖蟾蜍代表了具有80个物种的有魅力的无尾目多样化，其中25个来自中国。最近的新发现表明该属的多样性被低估了。在此，我们描述了一种来自中国贵州省从江县八沙自然保护区的新物种。该新物种与其同属物种的区别在于以下一系列形态特征：体型小（6只成年雄性的体长为22.9 - 25.6毫米，1只成年雌性的体长为27.1毫米）；头长大于宽；背部皮肤略粗糙，有小瘤；胸部和腹部为乳白色，有不规则黑斑；明显的腹侧腺体形成一条白线；手指无蹼和缘膜；趾蹼不发达，外侧缘膜窄；虹膜双色，上半部分为亮橙色，下半部分为银色；蝌蚪头部背面深褐色，有小的褐色不规则斑点，身体两侧有气囊状凸起。该新物种与所有已知同属物种的16S rRNA基因片段未校正距离大于5.3%，系统发育分析将该新物种与和聚类在一起。目前，该新物种仅在八沙自然保护区海拔约900米的一小片山地常绿次生林中被发现。文中讨论了其自然史和保护状况。
