2020年中国双翅目新分类阶元

New taxa of Diptera from China in 2020

本文总结了2020年中国双翅目分类研究的进展以及分类学者们对双翅目分类的科学贡献,并对中国双翅目新分类单元的种类、分布地、发表期刊以及发表新分类单元数量的学者进行了统计。基于统计得到的中国双翅目标本2020年发表的3新属113新种,本研究发现果蝇科(Drosophilidae)(31新种)、缟蝇科(Lauxaniidae)(17新种)和摇蚊科(Chironomidae)(17新种)新分类单元最多;云南(43新种)、西藏(19新种或新属)和四川(17新种或新属)发现的新分类单元最多;发表新分类单元最多的期刊为Zoo Keys(30新种或新属)、Zootaxa(27新种或新属)和《昆虫分类学报》(22新种或新属);发表新分类单元最多的双翅目学者分别为华南农业大学陈宏伟团队、中国农业大学杨定团队和南开大学王新华团队。

Aims:In order to outline the contributions and advances of Diptera taxonomy in China in 2020,we summarize the detailed information of the new taxa,species distribution,and publication cases.Methods:Potential source articles were searched and identified from online resources.The Chinese National Knowledge Infrastructure,Web of Science,Elsevier,Springer,and other related academic literature index databases were searched.Results:Totally three new genera and 113 new species of Diptera were reported from China in 2020.We ranked the publications from different perspectives:the most newly described taxa were found in Drosophilidae(31 new species),Lauxaniidae(17 new species),and Chironomidae(17 new species);the regions with the greatest number of new taxa were Yunnan(43 new species),Xizang(19 new species or genera)and Sichuan(17 new species or genera);the journals with the most published new taxa are Zoo Keys(30 new species or genera),Zootaxa(27 new species or genera)and Entomotaxonomia(22 new species or genera);The research groups that published the most new taxa are Hongwei Chen,Ding Yang,and Xinhua Wang.Conclusion:Some progress has been made in the Chinese Diptera classification in 2020,however,gathering a deeper understanding of the dipteran taxonomy remains challenging due to the relatively short research history and insufficient and uneven research foundation.Diptera is a major order of insects,with about 150,000 described species and perhaps more than a quarter of a million species.According to our statistics,113 new species were described in China last year,then it can be seen that the taxonomic research of Diptera in China has a long way to go.More professionals,more taxonomic group coverage,and wider international collaboration would contribute to the Chinese Diptera research to a higher level.
