[email protected] Abstract. An account of the taxonomic position of the genus Bracon Fabricius, 1804 is presented. In his monograph Wesmael (1838: 7-58) made a survey of 48 nominal species of Bracon occurring in Belgium. Out of the 48 species thirty-seven were described by Wesmael himself as new species, eleven more species had previously been described by Fabricius (three species), Nees (seven species) and Spinola (one species). The Bracon material studied by Wesmael is deposited in the Royal Belgian Institute of Natural Sciences, Brussels. Type (holo-, lecto-, paralectotype) designations are made for Wesmael’s species and neotype designations for Nees sensu Wesmael’s species. Redescriptions, comments on distributions and their taxonomic positions are presented. Palpibracon subgen. nov. is established (type species Bracon delibator Haliday, 1833) for fi ve Bracon species with long maxillary palpi in the Holarctic (four species) and Ethiopian Region (one species). The following fi fteen Bracon species names proved to be junior synonyms (valid names in italics): B. dichromus Wesmael, 1838 = B. carpaticus Niezabitowski, 1910 syn. nov.; B. erraticus Wesmael, 1838 = B. bellicosus Papp, 1971 syn. nov., = B. exarator Marshall, 1885 syn.
