Aim: The order Hymenoptera has rich biodiversity and provides essential ecosystem services. This study aims to catalogue and summarize new taxa of extant Hymenoptera based on published works in 2022.

Methods: We obtained and analyzed a total of 360 journal publications on the new taxa of extant Hymenoptera in 2022 by researching the available zoological databases.

Results: Across 360 journal articles, 1,698 new taxa were identified, comprising 7 subfamilies, 53 new genera, 25 new subgenera, 808 new species, 6 new subspecies, 334 new synonyms, 241 new combinations, 76 new status, 14 new names, 5 revived synonyms, 71 revived combinations, 1 revived name and 57 revived status, spanning across 17 superfamilies, 77 families, and 446 genera. The superfamilies Apoidea, Ichneumonoidea, and Vespoidea displayed the highest number of new species, accounting for approximately 25.9% (209/808), 21.0% (170/808) and 18.1% (146/808) of the total new species, respectively. In 2022, 71 journal articles were published detailing newly classified extant Hymenoptera taxa in China, comprising 165 new taxa. These include 5 new genera, 126 new species, as well as 4 newly recorded genera and 30 newly recorded species, spanning across 13 superfamilies, 31 families, and 83 genera. Notably, the superfamilies Ichneumonoidea, Tenthredinoidea, and Chalcidoidea accounted for the highest number of new species in Chinese extant Hymenoptera, contributing approximately 20.6% (26/126), 19.0% (24/126) and 17.5% (22/126) of the overall new Chinese species total, respectively. Globally, Asia accounted for the highest number of newly described species, approximately 55.9% (452/808), with East Asia leading the count at approximately 20.7% (167/808) of new species. At the national and regional administrative level, China contributed the highest number of new species, approximately 15.6% (126/808) of the total. Of the 360 articles published in 85 journals on the newly classified taxa of extant Hymenoptera, 353 were in English, 5 were in Chinese, 1 in French and 1 in Spainish. Among those, 314 articles from 79 journals reported the newly described species. In 2022, a total of 412 scholars contributed to naming Hymenoptera new species, with 76 scholars (18.4%) from China. Worldwide, 167 institutions preserved the holotypes of newly described Hymenoptera species, with 19 of them located in China, representing approximately 11.4% of the total.

Conclusion: These results indicate that China plays a key positive role in the global taxonomy of Hymenoptera.
