The species of “Ichneumon” (Hymenoptera) described by Linnaeus

Ichneumonidae in the Linnaean and other collections have been critically assessed with regard to their status as type-specimens of species described by Linnaeus. The generic placements of the 56 nominal species of Ichneumonidae (54 originally in Ichneumon and two in Mutilla) described by Linnaeus are established after study of the extant type-material. Lectotypes are designated for eleven of the species and one new synonymy is established. Notes are given on the 33 species originally described by Linnaeus in Ichneumon but now placed in other families.
