Abstract

Nine new species of the fungus-gnat genus Boletina Winnertz (B. falcata sp. n., B. hedstroemi sp. n., B. struthioides sp. n., B. kivachiana sp. n., B. fennoscandica sp. n., B. lapponica sp. n., B. subtriangularis sp. n., B. atridentata sp. n. and B. cordata sp. n.) are described from Russian Karelia, Finland and Sweden. The descriptions are based on recently collected specimens as well as on the old material deposited in the collection of the Museum of Natural History, Helsinki, Finland. Most of the collecting localities are situated in oldgrowth reservations or habitats suggested to protection. Detailed descriptions and illustrations of genitalia are given. Ecological data and information on closely related species are provided.
