Abstract Wrangel Island, Russia, because of its geographic position, harsh climate, yet surprising biodiversity, has been geobotanically studied and divided into various subzones. The distributions of the three species of the subgenus Tipula ( Arctotipula ) (Diptera: Tipulidae) that have been collected on Wrangel Island are related to these subzones. The predominantly Nearctic species, T. ( A. ) besselsoides Alexander, 1919, is newly recorded for Russia as well as on this island, where it was found to be the most widespread of the three species. The Holarctic species, T. ( A. ) salicetorum Siebke, 1870, is rarer, being found mostly in the climatically harsh northern and eastern areas of the island. The third species, T. ( A. ) oklandi Alexander, 1922, which was thought to have been more widespread formerly, is here confirmed only for Russia. It was collected in the warmest part of the island, and the female is illustrated for the first time. An illustrated key to both male and female adults is presented. Distribution maps are provided for all species, and the data on the distribution of oklandi have been adjusted.
