Abstract:

Aims: This study aims to systematically summarize the new taxa of extant Coleoptera published worldwide in 2024, with a specific focus on taxonomic additions from China. 

Methods: Literature and monographs were collected through targeted searches of taxonomic databases, review of key journals, and supplementary contributions from specialists. A total of 956 publications were analyzed in the study. 

Results: Globally, 2245 new extant Coleoptera taxa were published in 2024, comprising 3 new subfamilies, 6 new tribes, 1 new subtribe, 92 new genera, 27 new subgenera, 2068 new species, and 48 new subspecies. Additionally, 790 new combinations, 540 new synonyms, 105 raised and 36 downgrades taxa were recorded. China contributed the highest number of new species(subspecies), with descriptions including 11 new genera, 6 new subgenera, 591 new species, and 19 new subspecies. Within China, 10 new record genera, 2 new record subgenera, 108 new record species, and 6 new record subspecies were documented as well. Yunnan Province was the most productive region in China for both new taxa and new records, with 116 new species (subspecies) and 55 newly recorded species (subspecies) were discovered. Compared to 2023, the total number of new global Coleoptera taxa declined in 2024, while the number of new species described in China showed an increasing trend. 

Conclusion: This study provides an overview of the taxonomy of Coleoptera in 2024. Yunnan Province remains China's dominant contributor to both new taxa and new records. Compared to 2023, the number of new taxa of Coleoptera decreased globally, while the number of new species described from China showed an increasing trend.
