摘要:

本文总结了2023年全世界发表的现生蜘蛛目新分类单元。344位学者发表了75个国家和地区的1,311个新分类单元, 包括1新科70新属1,240新种, 隶属71科。这些新分类单元发表在63种刊物的315篇文章中, 其中科和属水平的修订、地区志或专著类的文章共有52篇, 占文章总数的16.5%; 运用DNA分子数据分析方法的论文共计53篇, 占文章总数的16.8%; 740个新种是基于雌雄两性标本发表, 占新种总数的59.7%, 500个新种仅基于雄或雌性标本发表, 占新种总数的40.3%。中国是2023年发现蜘蛛目新种最多的国家, 共412种, 占世界蜘蛛目新种总数的33.2%; 中国学者李枢强是2023年命名蜘蛛目新分类单元数量最多的学者, 共命名171个, 占世界新分类单元总数的13.0%。此外, 无论是命名蜘蛛目新分类单元数量还是参与命名新分类单元的学者数量, 均是中国学者位于第一。中国共有94位学者参与命名, 占世界新分类单元命名学者总数的27.3%; 这94位学者命名了中国和越南等11个国家和地区33个新属507个新种, 合计540个新分类单元, 命名新分类单元数量占世界41.2%, 该贡献率高于2022年的37.0%、2021年的33.8%和2016-2020年的平均贡献率28.1%。

Abstract

Aim: This paper focuses on the advancements in taxonomic studies of extant spiders in 2023 worldwide, with detailed statistical analyses of new taxa, type localities, arachnologists conducting such research, and journals publishing these works.

Progress: A total of 1,311 new taxa were described in 2023, including 1 new family, 70 new genera and 1,240 new species. They belong to 71 families, with type localities spanning across 75 countries and jurisdictions. The new taxa were documented by 344 arachnologists in 315 papers, published in 63 different journals. Out of these 315 papers, 52 (16.5%) comprised revisions of selected higher taxa (at family and genus levels), regional studies, and monographs. The proportion of papers incorporating DNA analyses made up 16.8% (totaling 53 papers). Among the 1,240 new species, 740 new species were published based on both male and female specimens, accounting for 59.7% of the total, and 500 new species only published based on male or female specimens, accounting for 40.3%. China is the country with the highest number of new species discovered, a total of 412, accounting for 33.2% of the global tally. With as many as 94 arachnologists naming new spider taxa, China becomes the country with the highest number of publishing spider taxonomists, accounting for 27.3% of the world’s total. Among them, the most prolific arachnologist is Shuqiang Li, who described a total of 171 new taxa, comprising 13.0% of the worldwide total for 2023. Altogether, Li and the other 93 Chinese colleagues described a total of 540 new taxa, comprising 33 new genera and 507 new species from China, Vietnam, and the other nine countries and jurisdictions. These new taxa described by Chinese arachnologists made up 41.2% of the 2023 global aggregate, higher than the Chinese output in 2022 (37.0%), 2021 (33.8%) and during the 2016-2020 period (28.1% on average).
