A revision of the Bracon Fabricius species in Wesmael’s collection deposited in Brussels (Hymenoptera: Braconidae)

In his monograph Wesmael (1838) made a survey of 48 Bracon Fabricius species occurring in Belgium. Out of the 48 species 37 have been described by Wesmael himself as new species, the rest of the species, 11 ones, divides among three authors: seven species by Nees, three species by Fabricius and one species by Spinola. Type (holo-, lecto-, paralectotype) designations of Wesmael’s species and neotype designations of Nees sensu Wesmael’s species are accomplished accompanied with their redescriptions, distributions and taxonomic positions. The Bracon material studied by Wesmael is deposited in Institut royal des Sciences naturelles de Belgique, Bruxelles. Palpibracon new subgenus is established for four Bracon species with long maxillar palp in the Holarctic Region. Fourteen species names proved to be junior synonyms. The species Bracon turolus Papp is revalidated. The subgeneric division of the Bracon species is briefly discussed.
