【目的】 鞘翅目昆虫是世界上多样性最为丰富的生物类群，也是生物多样性研究的重要类群之一。明确世界及国内鞘翅目分类单元的发表与修订情况，对于掌握我国近年鞘翅目研究现状，进一步推动国内鞘翅目多样性研究及生物多样性保护具有重要意义。【方法】 对2016-2020年间发表世界鞘翅目新分类单元文献进行检索和整理，并进一步分析。【结果】 经统计，这5年国内外共发表鞘翅目新分类单元18 058个，共涉及152个科，包括新种16 860个，新属1 187个，新科11个。数据显示，这5年，世界范围内的新分类单元数、新异名提出数及文章发表数均呈整体下降趋势；隐翅虫科等少数科成为热点研究类群。2016-2020年中国鞘翅目新分类单元共2 477个(占全世界的13.7%)，涉及73科，包括新种2 388个，新属87个，新科2个。【结论】 虽然国内学者发表的新种数和文章数占世界的相应比例呈整体上升趋势，但这5年，我国鞘翅目的新种仅有39.7%为国内学者发表，且国内作者数随年度呈下降趋势。总体而言，国际鞘翅目多样性研究有所下降，而国内鞘翅目昆虫多样性研究也并不乐观。

[Objectives]  The Coleoptera are the most diverse group of animals in the world and are therefore an important taxon for biodiversity research. Summarizing key revisions of coleopteran taxonomy both internationally and domestically is important, not only to understanding the current taxonomic status of the order, but also to promote research on beetle diversity and biodiversity protection in China. [Methods]  We searched, collated and analyzed taxonomic and phylogenetic literature on the Coleoptera published overseas and within China between 2016 and 2020. [Results]  A total of 18 058 new Coleopteran taxa have been described in the past five years. 16 860 new species, 1 187 new genera, and 11 new families. The number of new taxa, synonyms and articles published during this period have, however, been declining. 2 477 new taxa were described in China during the same period; 2 388 new species, 87 new genera and 2 new families, accounting for 13.7% of the all new taxa. [Conclusion]  Although the proportion of new species and articles published by Chinese researchers in the world has increased year by year, only 39.7% of new species of Coleoptera were described by Chinese researchers between 2016 and 2020. The number of Chinese authors has also been decreasing. In general, research on Coleopteran diversity has been declining worldwide, which is not optimistic for research on this taxon in China.
