Aims: This study aims to summarize the new taxa of Chinese Hemiptera and 28 other orders of Insecta (i.e., orders other than Coleoptera, Diptera, Lepidoptera, and Hymenoptera) in 2020.

Methods: We collected information about newly described taxa, including new genera, species, and subspecies for Chinese Hemiptera and 28 other insect orders in 2020 by searching journals and the Zoological Record database. Based on the described taxa and published literature, we compiled a catalogue of type specimens and a bibliography for new species of Chinese Hemiptera and other insects described in 2020. We also analyzed the biodiversity information provided by type specimens, such as authors, locations, and preservation sites.

Results: In 2020, a total of 349 new taxa, including 35 new genera, 311 new species, and 3 new subspecies, were described in Chinese Hemiptera and 28 other insect orders. The hotspots for the new species described were in Southwest China and the adjacent areas. Additionally, there are as many as 69 institutions that are designated for the deposition of type specimens; within these, the holotype was primarily collected in domestic collection institutions. In contrast, there were relatively few type specimens collected by foreign institutions, and those collected were mainly paratypes. The 349 new taxa described this year were contributed by 356 authors, and a total of 182 articles were published. Zootaxa and ZooKeys were the main publication journals for these descriptions.

Conclusion: This study provides baseline data for further in-depth studies in the temporal and spatial patterns of species evolution and biodiversity protection in China. Moreover, in the face of today's rapidly declining biodiversity, we should accelerate the construction of data platforms and the integration of diverse information sources to strengthen the biodiversity research and protection.
