Abstract

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.
