Following the publication of the'Catalogue of mammals in China(2021)'and the release of Taxonomy and Distribution of Mammals in China,the mammalian catalogue of China has garnered significant attention from research-ers worldwide.This surge in attention is primarily attributed to significant national research projects,such as the Second Qinghai-Xizang Plateau Scientific Expedition and Research Program,which have facilitated further exploration of Chi-na's biodiversity and enhanced our understanding of the mammalian fauna.Between 2022 and 2024,a series of new mammalian species have been established,augmenting the 2022 catalogue by 42 species.In order to present a compre-hensive overview of the valid mammalian taxa in China,we hereby present an updated edition of the'Catalogue of mam-mals in China(2024)'.The documentation conducted until the end of December 2024 revealed a total of 58 families,en-compassing 263 genera and comprising 736 valid mammalian species in China.
