Aim: The aim of this study is to catalogue and summarize new taxa of the order Hymenoptera published in 2021.

Methods: In 2021, 355 journal publications on new taxa in the order Hymenoptera were obtained and analyzed by researching the available zoological databases.

Results: Based on the collected journal publications, there were 1,152 records on the new taxa of Hymenoptera for 66 families and 416 genera in 21 superfamilies, including 5 new families, 4 subfamilies, 83 new genera, 3 subgenera, 1,054 new species, and 3 new subspecies. A total of 980 extant hymenopterans from 52 families and 332 genera in 18 superfamilies were recorded in 309 of the 355 journal publications, including 2 new families, 26 new genera, 3 new subgenera, 946 new species, and 3 new subspecies. Another 46 journal publications on fossil Hymenoptera recorded 172 extinct Hymenoptera from 27 families and 86 genera in 14 superfamilies, including 3 new families, 4 new subfamilies, 57 new genera, and 108 new species. In 2021, 235 new taxa from 34 families and 91 genera in 17 superfamilies were recorded in 83 of the 309 relevant journal publications in China. These include 3 new genera (1 extinct) and 232 new species (2 extinct). The above 2 new extant genera were described from Taiwan and Zhejiang, China. The five Chinese provinces with the most new species published in 2021 are Yunnan, Zhejiang, Fujian, Xizang, and Xinjiang. Based on the publications in 2021, Ichneumonoidea was the superfamily with the highest number of new species, accounting for 32.5% (307/946), 19.4% (21/108), and 37.0% (85/230) of the extant, extinct, and Chinese new species in the Hymenoptera database, respectively. Grouping the extant Hymenoptera new species by continental regions and subregions shows that 56.9% (538) of the new species were discovered in Asia, 28.6% (271) in East Asia and 24.3% (230) in China, which tops the list of regions, subregions, and countries with the most new species. Of the 355 publications in 76 journals, 348 were published in English, 4 in Chinese, and 3 in French.

Conclusion: These results indicate that the taxonomy of Hymenoptera in China plays an important positive role in expanding our understanding of the order Hymenoptera around the world.
