Acta Zoologica Academiae Scientiarum Hungaricae 43 (I), pp. 1-19, 1997 REVISION OF THE CHELONUS SPECIES DESCRIBED BY A. G. DAHLBOM (HYMENOPTERA, BRACONIDAE: CHELONINAE) J. Pai>i> Department of Zoology, Hungarian Natural History Museum H-1088 Budapest, Baross utca 13, Hungary In 1833 A. G. Dahlbom reported eight Chelonus Jurine species from Sweden of which six were described as new to science. Redescriptions and taxonomic status of the four species are presented, the further four species are referred to. New synonyms are: Microchelonus gravenhorstii (Nees, 1816) sen. syn. = Chelonus maculator Dahlbom, 1833, jun. syn.; Scltizoprymnus pullatus (Dahlbom, 1833) sen. syn.: = Sigalphus rufipes Herrich-SchäFFER, 1838, = Sigalpluts globosus SZÉPLIGETI, 1898, jun. syns. Designation of the neotype for the species Sigalphus (—> Microchelonus) fenestratus Nees. With 60 original figures. Key words: Chelonus, redescriptions, synonymies, taxonomic remarks INTRODUCTION In the year of 1833 A. G. DAHLBOM (1806-1859) published a paper with a report of eight Chelonus JURINE species from Sweden. From among the eight species six had been described as new species to science. In the subsequent checklist of the eight species the first names are the original species names given by DAHLBOM, the second names (in italics) indicate the present, valid specific names except one species (Cli. oculator) where the first name remained valid: Chelonus abdominator Dahlbom, 1833 = Ascogasterabdominator (Dahlbom) Chelonus fasciatus Dahlbom, 1833, jun. syn. = Ascogaster rufipes (Latreille, 1809), sen. syn. Chelonus maculator Dahlbom, 1833,jun. syn. = Microchelonus gravenhorstii (Nees, 1816), sen. syn. Chelonus nigritulus Dahlbom, 1833 = Microchelonus nigritulus (Dahlbom), comb. n. Chelonus oculator (Fabricius, 1775) Chelonus pedator Dahlbom. 1833 = Microchelonuspedator (Dahlbom), comb. n. Chelonus pullatus Dahlbom = Schizoprymnuspullatus (Dahlbom), comb. n. Chelonus scabriculus Dahlbom, 1833 = Ascogasterscabricula (Dahlbom) From among the eight species four were re-evaluated by HUDDLESTON (1984: Ch. abdominator, Ch. fasciatus and Ch. scabriculus) as well as by VAN ACHTERBERG (1982: Ch. oculator). The rest of the species (i.e. four spp.) are revised in the present study. Actazool. him ft. 4J, IW7 Hungarian Natural History Museum, Budapest
