Monograph A revision of the Bracon Fabricius species in Wesmael’s collection deposited in Brussels (Hymenoptera: Braconidae: Braconinae) Jenő PAPP Department of Zoology, Hungarian Natural History Museum, Baross utca 13, H-1088 Budapest, Hungary, and Kézmüves utca 14/A, H-1184 Budapest XVIII, Hungary. Email: [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. nov., = B. praetermissus Marshall, 1885 syn. nov., B. vectensis Marshall, 1885 syn. nov.; B. fuscicornis Wesmael, 1838 = B. levicarinatus Niezabitowski, 1910 syn. nov.; B. immutator Nees, 1834 = B. breviusculus Wesmael, 1838 syn. nov.; B. intercessor Nees, 1834 = B. laetus Wesmael, 1838 syn. nov.; B. larvicida Wesmael, 1838 = B. crassiusculus Szépligeti, 1901 syn. nov.; B. longicollis Wesmael, 1838 = B. subcylindricus Wesmael, 1838 syn. nov.; B. megapterus Wesmael, 1838 = B. biimpressus Telenga, 1936 syn. nov.; B. nigratus Wesmael, 1838 = B. orbicularis Niezabitowski, 1910 syn. nov.; B. osculator Nees, 1811 = B. coniferarum Fahringer, 1927 (Schmiedeknecht in litt.) syn. nov.; B. picticornis Wesmael, 1838 = B. vitripennis Ratzeburg, 1852 syn. nov.; B. titubatus Wesmael, 1838 = B. fuscipennis Wesmael, 1838 syn. nov. The species Bracon (Lucobracon) turolus Papp, 1984 is revalidated (suppressed under the name B. (Glabrobracon) nigriventris Wesmael, 1838 by Tobias & Belokobylskij 2000: 162). A historic discussion of the subgeneric division of the Bracon species is given. Keywords. Bracon, subgeneric division, type designation, redescription, host range. Papp J. 2012.

This material was taken by him mainly in the regions of Brussels and Liège. Of these 48 nominal species, 37 were described by Wesmael himself as new to science. The rest of the nominal species had already been described by earlier authors: three species by Fabricius, seven species by Nees ab Esenbeck and one species by Spinola. Wesmael’s braconid collection is deposited in the Royal Belgian Institute of Natural Sciences, Brussels, and the results of my study of Bracon species therein are presented here. Refl ections on the subgeneric system of the genus Bracon Fabricius, 1804 Fahringer (1925-1928) was the fi rst to arrange the Palaearctic Bracon species in subgenera and sections: he created three subgenera: Bracon s. str., Braconella Szépligeti, 1901 and Kulczynskia Niezabitowski, 1910, and within the subgenus Bracon s. str. four sections: Glabrobracon Fahringer, 1927, Lucobracon
