Title: <i>Tavastia yggdrasilia</i>, a new orthoclad midge (Diptera: Chironomidae) from Europe
Abstract: Abstract A new species of the chironomid genus Tavastia was frequently collected in wetlands of the River Dalälven lowlands in central Sweden from 2002 to 2007. Unpublished data revealed that the species has been known from Finland since 1974. The new species T. yggdrasilia can be separated from other Tavastia species by the combination of a gonostylus with strong crista dorsalis in proximal half, AR 0.93–1.16, and wing veins M3 + 4 and Cu1 without setae. A description of the male and the female is included, as is also a key to the males of the four known species of Tavastia. All records of T. yggdrasilia are from sites with mesotrophic or eutrophic conditions.

We also wish to express our gratitude to Jari Tuiskunen for preparations of the Finnish material and valuable sketches of wings and hypopygium, and to Elisabeth Stur for loans of material from Belarus and the Netherlands.
