The Asian leaf litter toads of the genus Smith, 1925 (Anura, Megophryidae) inhabit the forest floor and rocky streams in hilly evergreen forests and are widely distributed from southern China, west to north-eastern India and Myanmar, through mainland Indochina to Peninsular Malaysia and the Island of Borneo.
A new species of the Asian leaf litter toad genus from Guizhou Province, China is described. Molecular phylogenetic analyses, based on mitochondrial 16S rRNA and COI genes and nuclear RAG1 gene sequences indicated that the new species is genetically divergent from its congeners. The new species could be distinguished from its congeners by a combination of the following characters: (1) body of medium size in males (SVL 31.9 - 32.9 mm); (2) distinct black spots present on flanks; (3) toes rudimentarily webbed, with wide lateral fringes; (4) skin on dorsum shagreened with fine tiny granules and short ridges; (5) heels overlapped when thighs are positioned at right angles to the body; (6) tibia-tarsal articulation reaching interior corner of the eye.A new species of the Asian leaf litter toad genus from Guizhou Province, China is described.

1925年史密斯属（无尾目，角蟾科）的亚洲落叶蟾蜍栖息于丘陵常绿森林的森林地面和岩石溪流中，广泛分布于中国南部、西至印度东北部和缅甸，穿过中南半岛大陆至马来西亚半岛和婆罗洲岛。
描述了一种来自中国贵州省的亚洲落叶蟾蜍属新物种。基于线粒体16S rRNA和COI基因以及核RAG1基因序列的分子系统发育分析表明，该新物种在基因上与其同属物种存在差异。该新物种可通过以下特征组合与同属物种区分开来：（1）雄性体型中等（体长31.9 - 32.9毫米）；（2）体侧有明显的黑色斑点；（3）趾间有蹼迹，有宽的外侧缘；（4）背部皮肤有细小颗粒和短嵴；（5）大腿与身体成直角时，脚跟重叠；（6）胫跗关节到达眼内角。描述了一种来自中国贵州省的亚洲落叶蟾蜍属新物种。基于线粒体16S rRNA和COI基因以及核RAG1基因序列的分子系统发育分析表明，该新物种在基因上与其同属物种存在差异。该新物种可通过以下特征组合与同属物种区分开来：（（1）雄性体型中等（体长31.9 - 32.9毫米）；（2）体侧有明显的黑色斑点；（3）趾间有蹼迹，有宽的外侧缘；（4）背部皮肤有细小颗粒和短嵴；（5）大腿与身体成直角时，脚跟重叠；（6）胫跗关节到达眼内角。
