Protura are widespread, but their presence in the Arctic was first noted only ca. 70 years ago and is still little acknowledged. This work compiles taxonomic information on proturans in the Arctic regions and adds unpublished data from Northern Siberia. Currently, this fauna is represented by 23 species in two orders and 14 genera. The large cosmopolitan genus Eosentomon is represented by only four species, whereas Acerentomidae is much more diverse, with 19 species in 13 genera (eight Nipponentominae, five Acerentominae). Most of the Arctic species possess a larger number of setae than species living in temperate regions. Based on several unique characters, a new genus, Mastodonentomon, is erected for Nipponentomon macleani, and the species is re-described with the original description supplemented with new characters, including head chaetotaxy, seta length, and porotaxy. Proturan occurrence in the Arctic is limited to Beringia, but the majority of species have restricted distributions and none have been found in both the American Arctic and Siberia. This implies relict origins and high levels of proturan endemism in the Arctic. This emerging view on biogeographical history is, however, hampered by the limited extent of available data, which highlights the need for considerably greater survey efforts. A key to Arctic proturans is provided to facilitate further studies.

北极地区的原生动物，带有Mastodonentomon n的描述。gen。（A科，日本科）和已知北极分类群的钥匙

原生动物很广泛，但最初仅在约旦发现它们在北极的存在。70年前，仍然鲜为人知。这项工作汇编了北极地区proturan的分类学信息，并添加了北西伯利亚未发布的数据。目前，该动物区系由23个物种组成，分别为2目和14属。大型的世界性嗜曙菌属（Eosentomon）仅由四个物种代表，而A科（Acerentomidae）则更为多样，在13个属中有19种（八尾N科（Nipponentominae），五个cer科）。与生活在温带地区的物种相比，大多数北极物种拥有的刚毛数量更多。基于几个独特的性格，为日本清洁猫立起了新属Mastodonentomon。，并用原始描述重新描述该物种，并在其中附加了新特征，包括头部Chattotaxy，seta长度和porotaxy。北极的Proturan发生仅限于白令海，但大多数物种的分布受到限制，在美国北极和西伯利亚均未发现。这意味着北极地区的遗迹起源和大量的普特特种。但是，这种对生物地理历史的新兴观点由于可用数据的有限性而受到阻碍，这突出表明需要进行更大的调查工作。提供了北极proturans的关键，以促进进一步的研究。
