The Swedish entomologist, Karl-Johan Hedqvist (1917 -2009 described 261 species of insects, 260 species of Hymenoptera and one of Coleoptera, plus 72 genera and a small number of family-level taxa. These taxa are catalogued and the current depositories of the types are listed, as well as some brief notes on the history of the Hedqvist collection. We also discuss some issues that can arise when type-rich specimen collections are put on the commercial market.
