First description on female and tadpole of Nidirana chongqingensis Ma & Wang, 2023 (Anura, Ranidae) and its distribution expansion in Guizhou Province, China

During herpetological surveys in 2024-2025, we collected six adult specimens (3 males, 3 females) and five tadpoles of Nidirana from Zheng'an County, Guizhou Province, China. Molecular analyses of 16S and COI genes confirmed their identity as <i>N. chongqingensis</i>. We provide the first detailed description of the female morphology and tadpole characteristics of this species, revise its diagnostic features, extend its known distribution range from Chongqing to Guizhou, and offer foundational data for future conservation assessments.
