Abstract:

Aim: The aim of this study is to summarize the new taxa and taxonomic changes of Hymenoptera from China published in 2020.

Method: Through searching the available zoological databases and collecting data from Chinese hymenopterists, in 2020, 104 journal publications and 1 monograph related to the new taxa and taxonomic changes of Hymenoptera from China were obtained and analyzed.

Results: Based on these publications, 469 records of new taxa, new records and taxonomic changes of Hymenoptera from China were retrieved, including 4 new genera (1 extinct genus), 1 new subgenus, 321 new species (10 extinct species), 8 new combinations, 22 new synonyms, 1 newly recorded subfamily, 18 newly recorded genera, 93 newly recorded species, and 1 replaced name. In 11 records of them, 3 superfamilies, 3 families and 5 genera of extinct hymenopteran were involved. Another 458 records belong to 11 superfamilies, 29 families, 170 genera of extant Hymenoptera, of which 40 genera distributed in 6 families are only related to new distribution records or taxonomic changes. Among these 11 superfamilies, 9 superfamilies with new species published in 2020 include Symphyta: Tenthredinoidea (23 new species); Aculeata of Apocrita: Apoidea (29 new species), Chrysidoidea (2 new species), and Vespoidea (20 new species); Parasitica of Apocrita: Chalcidoidea (23 new species), Cynipoidea (12 new species), Ichneumonoidea (206 new species), Platygastroidea (4 new species), Trigonalyoidea (2 new species).

Conclusions: Among the 9 superfamilies, Ichneumonoidea had the largest number (206) of new species by covering about 2/3 of 321 new species published in 2020. Five provinces with more new species published in 2020 are Yunnan, Zhejiang, Xizang, Fujian, and Liaoning, covering about 1/2 of the 321 new species. Moreover, the current status and future development of Hymenoptera taxonomy were discussed here based on these results.
