Hello friends and colleagues,

The following articles are badly needed:

Tjeder, B. 1969. Three new Tipulidae from Sweden (Diptera). Opuscula Entomologica 34: 250-256.
Tjeder, B. 1973. A new species of Erioptera from Sweden (Dipt. Tipulidae). Entomologica Scandinavica 4: 111-114.
Stary, J. 1997. A new Erioptera from Switzerland/Valais (Diptera, Limoniidae). Bulletin de la Societe Neuchateloise des Sciences Naturelles 120: 145-148.

Thank you in advance.

P.S. I can offer many of the articles on Limoniidae by Savchenko in exchange.
