The present study is the result of a four-year project supported by the Swedish Taxonomy Initiative to collect and systematize the Lestremiinae. It fleshes out the skeleton presented in Jaschhof (1998) of this group for the Palearctic Region, bringing to bear the broad knowledge gained from the authors’ studies since 1998 from Japan, Malaysia, South Africa, and New Zealand and Mathias Jaschhof’s subsequent studies of the Mamaev types. More species of wood midges (n = 203) are now known from Sweden than any other country or all of the Western Hemisphere. The fact that until the 1990s only four species were known from all of Fennoscandia (Norway, Sweden, Finland, and Russian Karelia) and Denmark is a measure of the value of this work.
