Background Enchytraeids, or potworms, are tiny oligochaetes that are distributed worldwide in many terrestrial, freshwater and marine ecosystems. Despite their key role in the functioning of ecosystems, the diversity and abundance of Enchytraeidae are rarely studied due to the laborious process of species identification. The present study addresses this gap and sheds some light on the distribution and abundance of enchytraeids in the lands of the Northern Palearctic. The provided dataset constitutes the latest and comprehensive field sampling of enchytraeid assemblages across the Asiatic part of the Northern Palearctic, encompassing an original set of soil samples systematically collected throughout the region from 2019 to 2022. New information The dataset includes occurrences from 131 georeferenced sites, encompassing 39 species and 7,074 records. This represents the first dataset providing species-specific information about the distribution and abundance of terrestrial enchytraeids across an extensive geographic area covering the Asian sector of the Northern Palaearctic. The compiled dataset is the key for exploring and understanding local and regional enchytraeid diversity. It may also serve as a valuable resource for monitoring and conserving the entire soil biodiversity.

古北界北部的Enchytraeidas（环节动物门，Clitellata，Enchytraeida）的分类多样性和丰富度。1.亚洲部分

背景 Enchytraeids，或称罐虫，是微小的寡毛类动物，分布在世界各地的许多陆地、淡水和海洋生态系统中。尽管它们在生态系统的功能中发挥着关键作用，但由于物种鉴定的繁琐过程，Enchytraeidae 的多样性和丰富度很少被研究。本研究解决了这一差距，并揭示了古北界北部陆地上黑质动物的分布和丰度。所提供的数据集构成了古北极北部亚洲部分的 enchytraeid 组合的最新、全面的现场采样，包括 2019 年至 2022 年在该地区系统收集的一组原始土壤样本。新信息该数据集包括来自 131 个地理参考地点的事件，涵盖 39 个物种和 7,074 个记录。这是第一个数据集，提供了覆盖古北界北部亚洲部分的广阔地理区域内陆生 enchytraeids 的分布和丰度的物种特定信息。编译的数据集是探索和了解当地和区域 enchytraeid 多样性的关键。它还可以作为监测和保护整个土壤生物多样性的宝贵资源。
