本文以中国昆虫纲半翅目等除鞘翅目、双翅目、鳞翅目、膜翅目之外的其他29目昆虫类群为研究对象, 系统汇编了2022‒2023年新分类单元的基本信息、模式标本名录与文献名录, 分析了描述新种的热点地区、模式标本存放情况以及发表期刊等。2022-2023年中国半翅目等29目昆虫共描述了新科1个新属58个新种(新亚种) 668个, 共计727个新分类单元, 其中数量最多的3个目分别为: 半翅目(新科1个新属22个新种252个)、直翅目(新属19个新种183个)和襀翅目(新属1个新种54个)。螳䗛目、缺翅目、双尾目等8个目未描述新分类单元。基于省级行政区的分析表明, 新物种发现的热点地区分布于中国西南地区的云南、贵州、西藏、四川, 华南地区的广西、海南、广东, 华中地区的湖南、湖北, 以及华东地区的台湾、浙江、福建。新发表的668个物种(亚种)的5,252个模式标本保藏于70家国内外科研机构和高等院校, 包括正模和副模在内的模式标本中有95%以上保存在国内40所高校和11家科研机构, 境外3所大学和12个研究机构保存的模式标本以副模为主。2022‒2023年新分类单元命名和描述相关工作发表在35种期刊上, 共320篇文章。

Aims: This study aims to compile and update information on China’s newly described taxa of Hemiptera and 28 other orders of Insecta (excluding Coleoptera, Diptera, Lepidoptera, and Hymenoptera) from 2022 to 2023.

Methods: We summarized the list of type specimens and bibliographies for China’s newly described taxa of Hemiptera and 28 other insect orders during 2022-2023. The preservation locations of type specimens and the journals in which the new species were published were also analyzed.

Results: From 2022 to 2023, a total of 727 new taxa were published for Hemiptera and 28 other insect orders in China, comprising 668 new species/subspecies, 58 new genera and 1 new family. Among these, Hemiptera, Orthoptera, and Plecoptera were the top three orders with the highest number of new taxa. Specifically, Hemiptera had 252 new species, 22 new genera, and 1 new family; Orthoptera had 183 new species and 19 new genera; and Plecoptera included 54 new species and 1 new genus. No new taxa were reported for Mantophasmatodea, Zoraptera, Isoptera, and five other orders during this period. Based on an analysis of provincial administrative regions, hotspots for new taxa discovery were concentrated in Southwest China (Yunnan, Guizhou, Xizang and Sichuan), South China (Guangxi, Hainan and Guangdong), Central China (Hunan and Hubei), and Southeast China (Taiwan, Zhejiang, and Fujian). Yunnan led with 338 new species, representing 50.60% of the total, followed by Guangxi with 115 new species (17.22%), and Guizhou, Xizang, and Sichuan with 90, 88, and 79 new species, respectively. In total, 5,252 type specimens of the 668 new species and subspecies were deposited across 70 preservation facilities. Over 95% of holotypes and paratypes are preserved in 40 universities and 11 research institutions in China, while less than 5% of paratypes are deposited in 3 universities and 12 research institutions abroad. Type specimens are predominantly stored in universities, followed by research institutes and museums. These newly described taxa were published in 320 articles across 35 journals. Over 70% of these articles appeared in Zootaxa, ZooKeys and European Journal of Taxonomy. The Chinese journal Entomotaxonomiaaccounted for 4.69% of the articles, while Systematic Entomology and 24 other journals each published one relevant article.

Conclusion: This study provides a timely update on the biodiversity data of Hemiptera and 28 other insect orders in China for 2022-2023. It plays a crucial role in accelerating the development of data-sharing platforms and enhancing the understanding of insect biodiversity.
