An adult female of the dragonfly Tanypteryx hageni (Selys) was collected near the Kowesas River in western British Columbia (53°18' N latitude) in August 1995. This collection increases its northern range and represents the most northerly collection of any member of the family Petaluridae. While no larvae were collected, it is likely that the muskegs that occur in thc Kowesas River valley serve as the larval habitat. This distribution record supports thc prediction that Tanypteryx hageni is not restricted to mountain habitats, hut rather is a resident in low-elevation coastal forests in the northern part of its range.
