Four specimens (Amphibia, Anura, Dicroglossidae, Quasipaa) were collected in July 2022, at the Malipo Laoshan Provincial Nature Reserve, Wenshan, Yunnan Province, China. The specimens are relatively large in size, with an adult male head-body length ranging from 76. 2−77. 3 mm. The dorsal skin is smooth, dark brown in color, with no obvious folds. There are circular, bar-shaped, black markings on the back. Small warts are scattered on the ventral side, flanks, thighs, and groins. Black keratinous spines are distributed around the anus. Five or six large white circular warts are on the lateral side of the body. Light brown markings are on the throat. The fingertips are slightly enlarged, the lump below the finger joint is large, and the first finger is longer than the second. The toes are enlarged and have circular sucking discs at the fingertips, with full webbing between them, and the lump below the toe joint is obvious, dark brown horizontal stripes on the back limbs. It is similar to those specimen of Quasipaa delacouri specimen collected from Bac Kan Province, Vietnam (type locality). Phylogenetic analysis based on the mitochondrial cytochrome b (Cyt b) gene fragment showed that this specimen and Q. delacouri specimens clustered together, with a genetic distance of 6. 5%. Based on the morphological and phylogenetic analysis results, the specimen is identified as Q. delacouri, a new amphibian species recorded in China, and named “德氏棘蛙” in Chinese. The specimen is currently stored in the Key Laboratory of Freshwater Fish Reproduction and Development Ministry of Education, Southwest University. [ABSTRACT FROM AUTHOR]
