First description of the female and notes on tadpoles of Nidirana chongqingensis Ma & Wang, 2023 (Anura, Ranidae), Guizhou Province, China

The Nidirana Dubois, 1992 is widely distributed in East and Southeast Asia. In recent years, the species of this genus have been continuously updated, with 22 species recognized globally to date and 21 species recorded in China. Nidirana chongqingensis is a species described in 2023, previously only recorded from Qianjiang, Chongqing, China. With the deepening of surveys, this species has also been discovered in Zheng'an County, Guizhou Province, China, and its females and tadpoles have been first recorded herein. During herpetological surveys in 2024–2025, we collected 6 adult specimens (3 males, 3 females) and 5 tadpoles of Nidirana from Zheng'an County, Guizhou Province, China. Molecular analyses of 16S and COI genes confirmed their identity as N. chongqingensis . 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.
