Abstract

Larvae of the European species Eurylophella karelica Tiensuu, 1935, one of the Western Palaearctic representatives of the genus Eurylophella Tiensuu, 1935, were frst discovered in the south of the Komi Republic on the territory of the Koygorodskiy National Park and in the northern part of Kirov Region (north-east of the European part of Russia). Larvae were found in samples of zoobenthos and on fooded woody vegetation in the coastal parts of rivers. Tus, the range of the species is much wider than previously known. For the frst time, a genetic analysis was performed for this species, and a phylogenetic tree for closely related taxa was constructed.
