摘要:

甲螨是土壤动物主要的三大类群之一, 数量庞大且种类丰富。截至2020年, 中国已报道的甲螨仅占世界所有已知甲螨种类的7.6%, 这与我国已知甲螨种类真实物种状况仍有较大的差距。值此中国甲螨学开创100周年之际, 本研究以甲螨亚目为研究对象, 分别基于世界2020-2021年度和中国2007-2021年度发表的分类学文献资料, 编制了世界新增分类单元名录和近15年中国发表甲螨新种名录, 分析了新分类单元的地理分布、学者贡献和出版刊物情况。研究结果表明, 2020-2021年, 世界甲螨亚目共描述238个新分类单元, 包括新属及新亚属21个, 新种217个; 新分类单元发表的热点地区在埃塞俄比亚界、东洋界和新热带界; 描述的新分类单元由27位作者所贡献, 其中外国学者贡献占比高; 论文均发表在国外期刊上, Systematic and Applied Acarology是新分类单元发表的主要期刊。2007-2021年, 中国发表甲螨亚目新种183个, 无新科和新属发表; 新种发表的热点地区在华南区和西南区; 描述的新种由24位作者所贡献, 中国学者占主要贡献; 论文多发表在国外期刊上, Systematic and Applied AcarologyZootaxa是新分类单元发表的主要期刊。基于以上结果, 本文认为目前从事甲螨分类学研究的学者相对较少, 发表的新分类单元在类群分布和区域分布上均表现出极不均衡的现象。传统分类学未来的发展将面临机遇和挑战。

Abstract

Aims: Oribatid mites, with large numbers and rich diversity, are one of the three main groups of soil animals. Up to 2020, the recorded oribatid mite species in China represented only 7.6% of all known species in the world. However, the species diversity has generally not been scientifically evaluated, highlighting a big gap between known species and its actual number. To commemorate the 100th anniversary for the birth of Chinese Oribatology, this study aims to summarize the new taxa of Oribatida worldwide from 2020 to 2021, and new species in China from 2007 to 2021.
Methods: We catalogued new Oribatida taxa in the world from 2020 to 2021, and new species of Chinese oribatid mites from 2007 to 2021 based on the described taxa and published literature. We also analyzed the biodiversity information provided by those new taxa, such as geographical distribution, author contributions and publications.
Results: From 2020 to 2021, a total of 238 new taxa of Oribatida were described globally, including 21 new genera and new subgenera, and 217 new species. Hotspots for new taxa discovery were in the Ethiopian, Oriental and Neotropical realms. The new taxa described were contributed by 27 authors, most of whom were non-Chinese scholars. All papers were published in non-Chinese journals, with most publications in the journal Systematic and Applied Acarology. From 2007 to 2021, a total of 183 new species of oribatid mites were described in China, but no new family and new genus were published. The hotspots for new species discovery were in the southeast, southwest and adjacent areas. The new species described were contributed by 24 authors most of whom were Chinese authors. Papers were mainly published in international journals, with Systematic and Applied Acarology and Zootaxa being the main journal.
Conclusions: Based on the above results, it shows the limited research power studying on Oribatida, and highly uneven distribution of newly discovered species among families and regions. Opportunities and challenges will continue to coexist in the development of classical taxonomy.
