The family Axymyiidae includes four extant genera and nine species known from the Holarctic and Oriental regions, with only one species (Duda, 1930) occurring in Europe. The genus Sinclair, 2013 was first discovered in Alaska in 1962, but officially described only many years later. Up to now, the genus included one species Sinclair, 2013, known from two female specimens from western North America. During the study of the Diptera fauna in Paanajarvi National Park (Northwest Russia), one female specimen of , was found. It differs from the Nearctic by details of its female terminalia and is recognized as a new species, herein described as The biology and geographic distribution of is briefly discussed. The phylogenetic position of the genus, along with the family Axymyiidae is analyzed in the light of new molecular data, including sequences of three mitochondrial (ribosomal 12S and 16S and protein-encoding COI) and three nuclear genes (ribosomal 18S and 28S, protein-encoding CAD) for 72 terminal taxa. Axymyiidae is recovered as a monophyletic group with closest relatives in the infraorder Culicomorpha and representing the sister taxon to all the other species of Axymyiidae included in the analysis.
斧蚋科包括四个现存属和九个物种，分布于全北区和东洋区，仅有一种（Duda，1930）出现在欧洲。Sinclair属在1962年首次在阿拉斯加被发现，但多年后才被正式描述。截至目前，该属包括一个物种Sinclair，2013，已知有来自北美西部的两个雌性标本。在对帕亚纳贾尔维国家公园（俄罗斯西北部）的双翅目动物区系进行研究期间，发现了一只 的雌性标本。它在雌性尾器细节上与新北区的物种不同，并被认定为一个新物种，在此描述为 。对 的生物学和地理分布进行了简要讨论。根据新的分子数据，包括72个终端分类单元的三个线粒体基因（核糖体12S和16S以及蛋白质编码COI）和三个核基因（核糖体18S和28S、蛋白质编码CAD）的序列，分析了该属以及斧蚋科的系统发育位置。斧蚋科被确认为一个单系类群，其近亲位于蚊蠓亚目， 代表了分析中所包含的斧蚋科所有其他物种的姐妹分类单元。
