Abstract
BACKGROUND: The horned frog population, previously identified as Boulenophrys minor from Jiulong County, Sichuan Province, China, was recently proposed to be B. binchuanensis, based on geographical inference, which remains unconfirmed by specimen examination. NEW INFORMATION: We revisited this population and confirmed its identification as Boulenophrys binchuanensis in Jiulong County using molecular data from 16S and CO1 genes, complemented by morphological diagnosis. Additionally, we described its tadpoles and advertisement calls, extending the known range and informing conservation efforts.
