Aims: Coleoptera is the largest group of insects. The aim of this study is to summarize the new taxa and taxonomic changes of Coleoptera from the world in 2021, and sort out the new species and new records in China separately.

Methods: By searching the online databases and some papers from peer experts, 1,114 journal publications related to the new taxa and taxonomic changes of Coleoptera from the world were obtained and analyzed.

Results: Totally, 3,375 new taxa of Coleoptera from the world were reported in 2021, including 2 new subfamilies, 1 new supertribe, 9 new tribes, 3 new subtribes, 178 new genera, 36 new subgenera, 3,070 new species and 76 new subspecies. In addition, 1,071 new combinations, 485 new synonyms, 70 upgradations and 26 degradations were provided. There are 534 new staphylinids and 461 new scarabaeids, accounting for about 31.6% of the total species. China with the largest number of Coleoptera new species founded in the world, and it has published 13 new genera, 4 new subgenera, 635 new species, 6 new subspecies and 2 newly recorded subfamily, 13 newly recorded genera, 1 new recorded subgenera, 112 newly recorded species, 6 newly recorded subspecies in 2021. There are 204 new species of Coleoptera in China published in 2021 belong to Scarabaeidae, and Yunnan is the region with the highest number of new species discovered, with 172 new species reported.

Conclusion: Summarizing and sorting out taxonomic information timely has an important impact on guiding taxonomic research.
