Bëiträge zur Taxonomie der ostpalaearktischen Arten der Gattung Dusona CAMERON (Hymenoptera, Ichneumonidae)

1 Geometrid larvae were collected from larch and fir in the Swiss Alps in 1991-94. Eight geometrid species were found in sufficient numbers to rear out parasitoids: Agriopis aurantiaria, Bupalus piniarius, Epirrita autumnata, Eupithecia lariciata, Odontopera bidentata, Lycia isabellae and Semiothisa liturata were collected from larch, and Puengeleria capreolaria was obtained from fir. 2 Parasitoid species belonging to five different guilds and four families were obtained; however, the taxonomic status of some of these is not completely resolved. 3 The parasitoid complex of the larch-feeding species was totally different from that of Tortricidae and Tenthredinidae, which feed on the same host tree. In general, there was little overlap in the parasitoid complexes of the larch geometrids, with the most dominant parasitoid of each species reared from only one host. By contrast, many parasitoid species found during our study are also known to attack the same hosts or closely related hosts on different host tree species in different environments, suggesting that host specificity in geometrid parasitoids is more related to host taxonomy than to host plant or habitat.

“…As Dusona includes the Campopleginae species with the largest body sizes of up to more than 20 mm, e.g., in D. falcator (Fabricius, 1775), it is not surprising that they received the attention of entomologists early on in the 19 th century (e.g., Holmgren 1872; Thomson 1887) and the 20 th century (e.g., Teunissen 1947). Perhaps for the same reason, Dusona attracted the focus of Rolf Hinz and Klaus Horstmann, who were the first to prepare extensive species descriptions, conduct taxonomic revisions and compile keys for the Eastern and Western Palaearctic Dusona species (Hinz 1963(Hinz , 1977(Hinz , 1985(Hinz , 1990(Hinz , 1994Horstmann 1995Horstmann , 2009Horstmann , 2011Hinz and Horstmann 2004). Undoubtedly, the revisions of the Palaearctic Dusona set an excellent basis to work with the genus (Shaw et al 2016).…”

In the present time of biodiversity crisis, assessing species diversity by accurate and accessible taxonomic revisions is more crucial than ever. Parasitoid wasps are considered as both one of the most diverse and under-studied groups in the tree of life. Dusona Cameron, 1901 (Ichneumonidae, Campopleginae) is with 442 species one of the most species - rich genera of Darwin wasps, but despite the existence of recent keys, species identification has proven difficult to impossible to non-specialists. In this study, we examined about 1,500 Dusona specimens from recent and historical collections in Sweden and Switzerland. We provide a photographic guide to diagnostic characters and detailed plates for 57 out of 125 Western Palaearctic Dusona species, facilitating species identification based on existing keys. We add 11 and 3 species to the faunistic records of Sweden and Switzerland, respectively. Furthermore, we reconstruct the phylogeny of European Dusona based on four standard markers (COI, CAD, ITS2, 28S) for 45 species, complemented with a reliable reference barcode library for 46 species. Even though we can identify several morphologically distinct clades, we do not propose any new subgenera due to prevalent homoplasy of characters. While most species are well separated by barcodes, several morphologically distinct species have barely discriminatory barcode sequences (p-distances < 2%) or are even paraphyletic in this marker, indicating limitations in the applicability of barcodes for Darwin wasps. This study reveals severe gaps in the inventories of neglected taxa even for well-studied countries such as Sweden and Switzerland. As this study makes species determination for Western Palaearctic Dusona more accessible, we encourage more people, including non-specialists, to work with this genus.

Se presentan los resultados del estudio sobre medusas recolectadas en las islas de Cabo Verde durante la campaña TFMCBM/98 Cabo Verde. Cuatrocientos noventa y siete ejemplares fueron recolectados, identificándose treinta y dos especies, además de tres ejemplares de los cuales sólo dos pudieron ser determinados a nivel de género y uno a nivel de familia. Anteriormente nueve de estas especies habían sido citadas para las islas, relacionándose hasta el momento un total de cincuenta y seis registros para el área. De las especies identificadas, Clytia malayense cf. y Halocoryne orientalis cf., son nuevas citas para el océano Atlántico, sin embargo requieren confirmación. Se aportan comentarios de algunas especies.
