A revision of the Bracon (subgenera Bracon s. str., Cyanopterobracon, Glabrobracon, Lucobracon, Osculobracon subgen. n., Pigeria) species described by SZÉPLIGETI from the western Palaearctic Region (Hymenoptera: Braconidae, Braconinae) Author Papp, J. text Linzer biologische Beiträge 2008 2008-12-19 40 1 1741 1837 journal article 10.5281/zenodo.5431644 0253-116X 5431644 Bracon ( Glabrobracon ) marshalli SZÉPLIGETI ( Figs 184-204 ) Bracon obscurator NEES sensu MARSHALL 1885 (nec NEES 1834 ): 16 (in key) and 45 (no. 35, description) (existing authenticated specimens?), type locality: England (material originating from the FITCH’ s and BIGNELL’ s Collection, both naturalists reared the braconid specimens from the hosts Paulernis fulviguttella ZELLER and Homoesoma sinuella FABRICIUS, taken certainly in England ). - SHENEFELT 1978 : not mentioned. Bracon marshalli SZÉPLIGETI 1901a: 270 (in key, in Hungarian) and 1914 (1901): 191 (in key, in German) ( syntype series: three males , female latent), type locality: Budapest , Óbuda ( Hungary ), male lectotype (and four male paralectotypes ) in Magyar Természettudományi Múzeum, Budapest ; examined. - TELENGA 1936 : as valid species 151 (), 156 () (in key), 215 (redescription) (in Russian) and 353 (), 359 () (in key, in German). PAPP 1966: 387 (as synonym of B. obscurator NEES ). SHENEFELT 1978: 1575 (as synonym of B. obscurator NEES after PAPP l.c., literature up to 1969). TOBIAS 1986: 133 (as synonym of B. obscurator ). PAPP 1991: 73 (sp. rev., in Hungarian), 2000: as valid species 232 (in key) and 249 (type designation (partly), redescription, nearest allies), 2004: 177 (type designation and depository). R e m a r k s on the type series of Bracon marshalli (after PAPP 2000: 249 , partly modified): SZÉPLIGETI (1901: 270) described his species on the basis of female and male specimens (" "). The precise number of the syntype specimens and the locality name(s) were not indicated by him, i.e. the species has been described within the key and its detailed description was not presented in the traditional way. The species name "marshalli" was applied to the species " Br. obscurator Marsh. (non Nees)" (Szépligeti l.c.) or as a new name (nomen novum) for B. obscurator Nees sensu Marshall (1885: 45) . This taxonomic procedure explains the omission of the description. At present three male specimens (male lectotype and two male paralectotypes ) of B. marshalli are housed in the Hungarian Natural History Museum, these three males belong unambiguously to the original syntype series, reliable female specimen(s) was (were) not found (further two male paralectotypes are representing B. atrator NEES , see also PAPP 2004: 177 ). The three males were collected by Szépligeti in the localities "Budapest Óbuda" ( 15 April 1896 , two males ) and "Ungvár" (since 1945 Uzhgorod, Ukraine : Podkarpaty, one male , its designation see subsequently); the locality labels were partly handwriting by Szépligeti, thus the three specimens in question are considered as authentic ones. Furthermore, the three males were placed under the name " Bracon marshalli SZÉPL. " in the collection set up by SZÉPLIGETI himself and, consequently, I name-labelled them accordingly (in the years 1960ies Szépligeti’s original braconid collection was re-arranged by me). One male was designated as the lectotype and the two males as the paralectotypes , Hym. Typ. Nos 1340 ( lectotype ), 1341 and 11014 ( paralectotypes ) ( PAPP 2004: 177 ). The latter male paralectotype (no. 11014) is herewith designated: (first label) "Ungvár" (with Szépligeti’s handwriting) / "Szépligeti" (printed); (second label with my handwriting) "Kárpátalja / Ukraine "; (third label) " Bracon marshalli Szépl. " (with my handwriting) / "det. Szépligeti" (printed); fourth label is the paralectotype card, fifth label is with the inventory number 11014. The three male type specimens are in poor condition. The lectotype no. 1340: (1) micropinned; (2) left antenna deficient, i.e. with 12 antennomeres; (3) metasoma missing. The paralectotype no. 1341: (1) micropinned, (2) head, left fore wing, left fore leg and metasoma missing. The paralectotype no. 11014: (1) micropinned, pin pricked through left fore and right hind wings hence fore left wing medially somewhat damaged, (2) metasoma missing. The female and male specimens, serving for the subsequent re-description, were selected scrupulously by me (and re-named by me as B. marshalli ) from among the huge material accumulated in the Hungarian Natural History Museum and named mainly by routine identification as B. obscurator , a species very similar to B. marshalli .
