    Arbetet med donationer av insektsamlingar vid Naturhistoriska Riksmuseet2014In: Entomologisk Tidskrift, ISSN 0013-886X, Vol. 134, p. 153-162Article in journal (Other (popular science, discussion, etc.))
    Abstract [en]

    We describe the work with donated insect collections at the Swedish Museum of Natural

    History (NRM) in Stockholm, Sweden. The museum receives donations yearly from

    amateur entomologists, and they are an important contribution to the enrichment of the

    collections. For the collector it is satisfying that a public institution takes on the long term

    responsibility of safeguarding the scientific value in a collection, curating and making it

    available for study. Significant donations in the last years include that of Lars Huggert

    (Hymenoptera, Coleoptera), Hans Bartsch (Diptera) and Anders N. Nilsson (aquatic Coleoptera)

    to name a few. The curatorial and digitizing workload at the Entomology collection

    are unfortunately not matched by staff funding, and as at other European museums

    volunteer work constitute vital and invaluable help. We acknowledge especially some of

    the volunteer work in the Coleoptera and Hymenoptera collections. Recently we have engaged

    with amateur entomologists by organizing taxon-specific workshops at the museum

    which has stimulated exchange and collaboration. The Hymenoptera-day was visited by 30

    participants, and the Diptera-meeting by 49. As an example of what happens with a donation

    once it reaches the museum, we describe the work with a recent Coleoptera collection

    donation by Jan Olsson, Vallentuna. A few highlights from the unidentified material,

    including the Archostematan beetle Priacma serrata (Cupedidae) and the false jewelbeetle

    Schizopus laetus (Schizopodidae), are presented as they were new to the NRM collections.

    We also bring attention to two new websites: www.naturarv.se is the webportal presenting

    digitized material in Swedish natural history collections. Both metadata on specimens and

    photos are made searchable here. We also launch a new webpage at www.nrm.se/insektsdonationer

    where we write about new donations to the Entomology collections, with Jan

    Olsson’s Coleoptera collection first out.

    Abstract [sv]

    En regnig och blåsig höstdag den 13 november1916 invigde kung Gustav V Naturhistoriskariksmuseets nya lokaler i Frescati, en monumentalbyggnad på granitsockel med mörkt rött tegeli fasaderna (Fig. 1). Den fantastiska kupolenmed sitt koppartak och glas har nyligen genomgripanderenoverats och framträder i skick somnytt. I kupolen var det tänkt att en Foucault´spendel skulle hänga. Diskussioner om pendelnhar nyligen åter initierats av Riksmusei vänner.De rikliga utsmyckningarna är värda att tittaefter. De flesta missar nog tyvärr de två bamsigabjörnungarna som pryder entrén från stora vägennär museet fått nya infarter. Samma år utkom boken”Naturhistoriska riksmuseets historia, Dessuppkomst och utveckling” utgiven av KungligaVetenskapsakademien. Boken kan sägas varasamlingarnas historia. Där beskrivs hur museetär årsbarn med Vetenskapsakademien, som närden grundades 1739 av bl. a. Linné också inrättadeett skåp för naturalier. Av den anledningenfirade Naturhistoriska riksmuseet sitt 250 års jubileummed pompa och ståt år 1989.Mindre än ett decennium efter att NaturhistoriskaRiksmuseet flyttade till Frescati, år 1925,bildades föreningen Riksmusei Vänner somstödjer museet på många olika vis.

    Abstract [en]

    The Swedish entomologist, Karl-Johan Hedqvist (1917–2009) described 261 species of insects, 260 speciesof Hymenoptera and one of Coleoptera, plus 72 genera and a small number of family-level taxa. Thesetaxa are catalogued and the current depositories of the types are listed, as well as some brief notes on thehistory of the Hedqvist collection. We also discuss some issues that can arise when type-rich specimencollections are put on the commercial market.

    Abstract [en]

    A brief history of entomology at the Swedish Museum of Natural History for the period 1915-1923 is presented in chronicle form. The time circumscription has its background in a recent 100th anniversary of the current museum building, for which there was work on an anniversary book, which has not appeared, and this is based on a contribution originally intended for that book. It concerns primarily the Entomology department (which ended as a unit in 2013 when it was part of a fusion into a Zoology department) but also includes the Entomological Society of Stockholm to the extent it has been based at the museum, as well as insect-related work in other museum departments. The chronicle gives plenty of examples of research and researchers, other staff and routines, collection growth and management, collecting expeditions and publications, work environment issues and everyday life at the department.

    Abstract [en]

    The question of who can be considered Sweden’s first female entomologist is not easy toanswer and depends a lot on criteria; here it leads to a more general survey of women in Swedish entomology. Several persons who are candidates for being considered entomologist pioneers are presented, and the conditions for women to engage in entomology are briefly discussed. Such candidates include the following persons. Queen Lovisa Ulrika, Linnaeus’ benefactor, had an insect collection. The first female member of the Entomological Society in Stockholm was Signe Nordenskjöld in 1892. While Cecilia Andersson seems to be the first independent, active female insect collector in Sweden, in the early 20th century. Ida Trotzig collected Lepidoptera in Japan for the Stockholm museum. At that time, preparator Signe Ramberg and illustrator Therese Ekblom at the Stockholm museum were the first female professional entomologists. Only later, the entomological societies included somewhat larger number of female entomologists, and the first woman to get a PhD in entomology in Sweden was Christine Dahl, who also became the first female entomologist full professor.

    North European gall-inducing Euura sawflies (Hymenoptera, Tenthredinidae, Nematinae)2017In: Zootaxa, ISSN 1175-5326, E-ISSN 1175-5334, Vol. 4302, p. 1-115Article, book review (Refereed)
    Abstract [en]

    The sawfly genus Euura of the tenthredinid subfamily Nematinae, in which species level taxonomy has long been regarded as controversial, is particularly species rich in northern parts of the Holarctic. Among a majority of species with more or less free-living larvae, a sizeable minority belongs to a monophyletic lineage whose larvae complete their whole development in galls. We present illustrated keys to the adults and galls of 66 gall-inducing Euura species that occur, or might occur, in northern Europe. The distribution of these species is briefly reviewed, with an emphasis on the fauna of Sweden, where 55 species are now definitely recorded, two of them for the first time (E. bigallaeE. myrtilloidica). The species-level taxonomy of gall-inducing Euura remains partly problematic. Nominal species described on the basis of experimentally tested or assumed host plant specificity, but which cannot be recognised using morphological or genetic characters, are treated as conspecific with currently indistinguishable segregates ("host-plant races") associated with other Salix species. 20 new synonymies are proposed (valid names in parentheses): Eupontania acutifoliae baltica Vikberg & Zinovjev, 2006 and Pontania acutifoliae daphnoides Zinovjev, 1993 (Euura acutifoliae(Zinovjev, 1985)), Euura boreoalpina Kopelke, 2001 (Euura lanatae Malaise, 1921), Euura cinereae Kopelke, 1996 preoccupied and Euura lapponica Kopelke, 1996 preoccupied (Euura auritae Kopelke 2000), Euura gemmacinereae Kopelke, 2001 and E. nigritarsis Cameron, 1885 (Euura mucronata (Hartig, 1837)), Euura phylicifoliaeKopelke, 2001 (Euura myrsinifoliae Kopelke, 2001), Nematus westermanni Boheman, 1852 nomen oblitum (Euura scotaspis (Förster, 1854) nomen protectum), Nematus acerosus Hartig, 1840 (Euura saliciscinereae (Retzius, 1783)), Nematus alienatusFörster, 1854 and Phyllocolpa rolleri Liston, 2005 (Euura leucapsis (Tischbein, 1846)), Nematus angustus Hartig, 1837 (Euura atra (Jurine, 1807)), Nematus erythropygusFörster, 1854 (Euura leucosticta (Hartig, 1837)), Nematus impunctatus Herrich-Schäffer, 1840 (Euura amerinae (Linnaeus, 1758)), Pontania carinifrons Benson, 1940 and Phyllocolpa plicaglauca Kopelke, 2007 (Euura destricta (MacGillivray, 1923)), Pontania obscura Kopelke, 2005 (Euura bridgmanii (Cameron, 1883)), Pontania viminalis var. lugubris Enslin, 1918 and Eupontania collactanea rosmarinifoliae Vikberg & Zinovjev, 2006 (Euura collactanea (Förster, 1854)). Euura weiffenbachiella nom. nov. is proposed as a replacement name for Euura weiffenbachii Ermolenko, 1988; preoccupied in Euuraby Pteronidea weiffenbachi Lindqvist, 1958 (Euura piliserra (Thomson, 1863)). Lectotypes are designated for the following 9 taxa: Euura insularis Kincaid, 1900, Euura lanatae Malaise, 1921, Euura lappo Malaise, 1921, Euura lappo var. hastatae Malaise, 1921, Nematus acerosus Hartig, 1840, Nematus leptocerus Förster, 1854, Nematus vallisnierii Hartig, 1837, Pontania megacephala Rohwer, 1908, and Pontania piliserra var. mascula Enslin, 1915. Because of secondary homonymy within Euura, the valid name of the Nearctic species E. arctica MacGillivray, 1919 is E. delicatula (MacGillivray, 1919). The Nearctic Euura megacephala is removed from synonymy with the Holarctic E. destricta and treated as a valid species. 34 species names are newly combined with Euura.

    A review of West Palaearctic Hoplocampa species, focussing on Sweden (Hymenoptera, Tenthredinidae)2019In: Zootaxa, ISSN 1175-5326, E-ISSN 1175-5334, Vol. 4615, no 1, p. 1-45Article in journal (Refereed)
    Abstract [en]

    Fourteen Hoplocampa species have been recorded in the West Palaearctic. We provide an illustrated key to these species, together with H. tadshikistanica, which is so far only known from Tadshikistan, but could occur in the West Palaearctic. The suitability of genetic sequencing for identification, particularly of larvae, is discussed. COI barcoding reliably distinguishes all European species which have been sampled (only H. phantoma lacks data), except for H. fulvicornis and H. minuta, which can be identified using nuclear sequences. Distributions in the Fennoscandian countries are outlined, with particular reference to Sweden. Hoplocampa chrysorrhoea is recorded for the first time in Scandinavia, from southern Sweden. Lectotypes are designated for twelve nominal taxa: Allantus ferrugineus Panzer, 1802, Hoplocampa chrysorrhoea var. nigrita Enslin, 1914, H. fabricii W. F. Kirby, 1882, H. oertzeni Konow, 1888, H. pectoralis Thomson, 1871, Hylotoma ferruginea Fabricius, 1804, Tenthredo alpina Zetterstedt, 1838, T. brevis Klug, 1816, T. chrysorrhoea Klug, 1816, T. crataegi Klug, 1816, T. plagiata Klug, 1816, and T. rutilicornis Klug, 1816. Hoplocampa minuta forma dudai Gregor, in Gregor & Bata, 1942 is a new synonym of H. fulvicornis (Panzer, 1801).

    The West Palaearctic Dineura species, focussing on Sweden (Hymenoptera, Tenthredinidae)2019In: Zootaxa, ISSN 1175-5326, E-ISSN 1175-5334, Vol. 4612, no 4, p. 501-517Article in journal (Refereed)
    Abstract [en]

    Four Dineura species are now considered to occur in the West Palaearctic, including northern Europe, but D. parcivalvis has not been found in Scandinavia. Dineura pullior Schmidt & Walter, 1995 is treated as a new junior subjective synonym of D. virididorsata (Retzius, 1783). An illustrated key to adults is presented. Lectotypes are designated for seven nominal taxa: Dineura stilata var. virilis Enslin, 1918, Dineura testaceipes var. nigriventris Enslin, 1915, Dineura virididorsata var. dorsalis Enslin, 1915, Nematus posticus Förster, 1854, Nematus xanthocerus Hartig, 1840, Nematus xanthopus Zaddach, 1876, and Tenthredo (Allantus) stilata Klug, 1816. Distributions in the Fennoscandian countries are outlined, with particular reference to Sweden.

    The West Palaearctic Pseudodineura and Endophytus species (Hymenoptera, Tenthredinidae)2019In: Zootaxa, ISSN 1175-5326, E-ISSN 1175-5334, Vol. 4614, no 3, p. 511-528Article in journal (Refereed)
    Abstract [en]

    Six valid species of Pseudodineura are now recognised as occurring in the West Palaearctic, and the only described species of the related genus Endophytus. Larvae of all species are leaf-miners in Ranunculaceae. An identification key to adults is provided, followed by species commentaries which include summarised data on taxonomy, larval host plants, and distribution, with particular reference to Sweden. Whereas identification of some specimens using morphological characters may not be possible, each species apparently has a distinct COI barcode sequence. Pseudodineura heringi(Enslin, 1921) is a new junior synonym of P. parvula (Klug, 1816). Pseudodineura mocsaryi Zombori, 1976 and P. scaligera Zombori, 1979 are new junior synonyms of P. clematidisrectae Hering, 1935. Lectotypes are designated for: Dolerus minutus Hartig, 1837, Pelmatopus clematidis Hering, 1932, P. enslini Hering, 1923, P. heringi Enslin, 1921, and P. mentiens var. konowi Enslin, 1921.

    New and poorly-known sawflies (Hymenoptera, Tenthredinoidea) from Sweden, with taxonomic notes on Palaearctic Heptamelus species described by Swedish authors.2018In: Entomologisk Tidskrift, ISSN 0013-886X, Vol. 139, p. 119-131Article in journal (Refereed)
    Abstract [sv]

    First records from Sweden of eight sawfly taxa are presented: Arge annulata Konow, 1891

    (Argidae), Allantus cingillipes (Kontuniemi, 1947), Allantus melanarius (Klug, 1818),

    Apethymus cereus (Klug, 1818), Dolerus liogaster schneideri Kiaer, 1898, Fenusella hortulana

    (Klug, 1818), Monophadnus spinolae (Klug, 1816), and Tenthredo mandibularis

    Fabricius, 1804 (Tenthredinidae). The problematic taxonomic status of Arge annulata is

    discussed, and it is recorded for the first time from Germany and Estonia. For Heptamelus

    dahlbomi (Thomson, 1870) (Heptamelidae): a lectotype is designated for Caenoneura

    dahlbomi, H. ussuriensis Malaise, 1931 is placed as its junior synonym, Athyrium distentifolium

    recorded as a new host, and additional distribution data are presented, including the

    first records from Austria. A lectotype is designated for Heptamelus magnocularis Malaise,

    1931, and this species briefly compared with H. dahlbomi.

    The genera of Nematinae (Hymenoptera, Tenthredinidae)2014In: Journal of Hymenoptera Research, ISSN 1314-2607, Vol. 40, p. 1-69Article in journal (Refereed)
    Abstract [en]

    Recent phylogenetic studies on Nematinae based on DNA sequences have shown extensive incongruencies with current nomenclature of genus-group taxa. Here, we expand previous DNA sequence datasets based on three genes (CoI, Cytb, and EF-1α), to include a fourth (NaK) and more genera. The analyses largely confirm the previous findings, particularly the existence of two well-supported large clades, Euura and Pristiphora, together comprising more than 75% of the species of Nematinae. Basal relationships within these two clades remain poorly resolved, mirroring the difficulties in delimiting genera based on morphology. In addition, a moderately supported small clade, Nematus, is found. The relationships between the Euura, Pristiphora, and Nematus clades are uncertain. Therefore, to stabilize the nomenclature we treat these clades as genera. This taxonomic treatment results in numerous new combinations of species names. The following synonymies are proposed for the available genus-group names. Synonyms of Euura Newman, 1837: Cryptocampus Hartig, 1837, Euura Agassiz, 1848, Pontania Costa, 1852, syn. n., Epitactus Förster, 1854, syn. n., Amauronematus Konow, 1890, syn. n., Holcocneme Konow, 1890, syn. n., Pachynematus Konow, 1890, syn. n., Holcocnema Schulz, 1906, syn. n., Holcocnemis Konow, 1907, syn. n., Pteronidea Rohwer, 1911, syn. n., Pontopristia Malaise, 1921, syn. n., Brachycoluma Strand, 1929, syn. n., Decanematus Malaise, 1931, syn. n., Pikonema Ross, 1937, syn. n., Phyllocolpa Benson, 1960, syn. n., Eitelius Kontuniemi, 1966, syn. n., Gemmura E.L.

To facilitate the identification of Nematinae genera, we provide an illustrated key to the 31 extant genera of world Nematinae.

    Sawflies (Hymenoptera, Symphyta) newly recorded from Sweden2014In: Entomologisk Tidskrift, ISSN 0013-886X, ISSN 0013-886X, Vol. 135, no 3, p. 135-146Article in journal (Refereed)
    Abstract [en]

    The first records from Sweden of 15 species of sawfly are presented: 2 species of Pamphiliidae,1 Argidae, 11 Tenthredinidae and 1 Cimbicidae. Of these, Empria camtschaticaand E. plana are also recorded for the first time in Europe. An illustrated key is providedto distinguish them from similar species (E. immersa, E. fletcheri). Rhogogaster polarisLindqvist, 1964 is treated as a valid species (species revocata). The number of Symphytaspecies that occur in Sweden and possible deficits in recording strategies are discussed.

    The West Palaearctic genera of Nematinae (Hymenoptera, Tenthredinidae)2019In: ZooKeys, ISSN 1313-2989, E-ISSN 1313-2970, Vol. 875, p. 63-127Article in journal (Refereed)
    Abstract [en]

    Keys to adults and larvae of the genera of West Palaearctic nematine sawflies are presented. Species of some of the smaller genera are keyed, and their taxonomy, distribution, and host plants reviewed, with a geographic focus on north-western Europe, particularly Sweden. Dinematus Lacourt, 2006 is a new junior subjective synonym of Pristiphora Latreille, 1810, resulting in the new combination Pristiphora krausi (Lacourt, 2006) for the type species of Dinematus. Hemichroa monticola Ermolenko, 1960 is a new junior subjective synonym of Hemichroa australis (Serville, 1823). Lectotypes are designated for Tenthredo opaca Fabricius, 1775, Mesoneura opaca var. nigerrima Enslin, 1914, Mesoneura opaca var. obscuriventris Enslin, 1914, Nematus hypogastricus Hartig, 1837, Nematus alnivorus Hartig, 1840, Leptopus rufipes Förster, 1854, Nematus protensus Förster, 1854, and Platycampus luridiventris var. pleuritica Enslin, 1915. A phylogenetic analysis based on four genes (mitochondrial COI and nuclear NaK, POL2, and TPI) supports the current generic classification.

    Life history of Parnips and the evolutionary origin of gall wasps2018In: Journal of Hymenoptera Research, ISSN 0219-8916, E-ISSN 1843-5610, Vol. 65, p. 91-110Article in journal (Refereed)
    Abstract [en]

    By mechanisms that are still unknown, gall wasps (Cynipidae) induce plants to form complex galls, inside which their larvae develop. The family also includes inquilines (phytophagous forms that live inside the galls of other gall inducers) and possibly also parasitoids of gall inducers. The origin of cynipids is shrouded in mystery, but it has been clear for some time that a key group in making progress on this question is the ‘figitoid inquilines’. They are gall-associated relatives of cynipids, whose biology is poorly known. Here, we report the first detailed data on the life history of a figitoid inquiline, the genus Parnips. Dissections of mature galls show that Parnips nigripes is a parasitoid of Barbotinia oraniensis, a cynipid that induces single-chambered galls inside the seed capsules of annual poppies (Papaver rhoeas and P. dubium). Galls with pupae of Parnips nigripes always contain the remains of a terminal-instar larva of B. oraniensis. The mandibles of the terminal-instar larva of P. nigripes are small and equipped with a single sharp tooth, a shape that is characteristic of carnivorous larvae. The weight of P. nigripes pupae closely match that of the same sex of B. oraniensis pupae, indicating that Parnips makes efficient use of its host and suggesting that ovipositing Parnips females lay eggs that match the sex of the host larva. Dissection of young galls show that another species of Parnips, hitherto undescribed, spends its late larval life as an ectoparasitoid of Iraella hispanica, a cynipid that induces galls in flowers of annual poppies. These and other observations suggest that Parnips shares the early endoparasitic-late ectoparasitic life history described for all other cynipoid parasitoids. Our findings imply that gall wasps evolved from parasitoids of gall insects. The original hosts could not have been cynipids but possibly chalcidoids, which appear to be the hosts of several extant figitoid inquilines. It is still unclear whether the gall inducers evolved rapidly from these ancestral parasitoids, or whether they were preceded by a long series of intermediate forms that were phytophagous inquilines.

    An annotated catalogue of the types of Chrysididae (Hymenoptera) at the Swedish Museum of Natural History, Stockholm, with brief historical notes2015In: ZooKeys, ISSN 1313-2989, E-ISSN 1313-2970, Vol. 495, p. 79-132Article in journal (Refereed)
    Abstract [en]

    A critical and annotated catalogue of 72 types of Chrysididae (Hymenoptera) belonging to 53 species and subspecies housed in the Swedish Museum of Natural History is given. The lectotypes of Chrysis diversa Dahlbom, 1845, C. soror Dahlbom, 1854, Chrysura sulcata Dahlbom, 1845 and Holopyga amoenula Dahlbom, 1845 are designated. The previous lectotype of Chrysis diversa Dahlbom, 1845 is set aside. Five new synonymies are proposed: Chrysis elegans var. smaragdula Trautmann, 1926 (currently C. elegans ssp. interrogata Linsenmaier, 1959 repl. name for smaragdula Trautmann, nec Fabricius, 1775), syn. n. of C. confluens (Dahlbom, 1845); C. eximia Mocsáry, 1889, syn. n. of C. poecila Mocsáry, 1889; C. pyrrhina Dahlbom, 1845, syn. n. of C. erythromelas Dahlbom, 1845; C. separata Trautmann, 1926, syn. n. of C. lateralis Dahlbom, 1845; C. sicula Abeille de Perrin, 1877, syn. n. of C. erythromelas Dahlbom, 1845. Chrysis serena Radoszkowski, 1891 is the first available name for C. pyrrhina sensu auctorum. C. erythromelas Dahlbom, 1845 is revaluated as valid species. The neotype of Chrysis inaequalis Dahlbom, 1845 is designated in the Linsenmaier collection (NMLS). Illustrations of 34 types are given.

    Snapshot of the Hymenopteran fauna of Stora Karlsö2017In: Entomologisk Tidskrift, ISSN 0013-886X, Vol. 138, p. 71-91Article, book review (Refereed)
    Abstract [en]

    Stora Karlsö is a small island close to Gotland in the Baltic Sea of which the Hymenopteran

    fauna has not been extensively studied before. In August 2014, a team of eight persons

    carried out an inventory of Hymenoptera, mainly the parasitoid wasps and sawflies, on

    the island. Sampling was done with Malaise traps for a period of 22 days, complemented

    with vegetation sweeping, branch shaking and opportunistic handpicking during a five day

    sojourn. As a result, about 200 species of parasitoid wasps and 14 sawflies are reported for

    Stora Karlsö for the first time. Eleven species are reported as new to Sweden: The sawfly

    Athalia cornubiae Benson, 1931, the gasteruptiid Gasteruption opacum (Tournier, 1877),

    the diapriid Spilomicrus rufitarsis (Kieffer, 1911), the eulophid Entedonomphale bulgarica

    Boyadzhiev & Triapitsyn, 2007, the braconids Bracon rozneri Papp, 1998 and Gnamptodon

    decoris (Förster, 1862), and the ichneumonids Bathythrix maculata (Hellén, 1957),

    Heterischnus filiformis (Gravenhorst, 1829), Lissonota picticoxis Schmiedeknecht, 1900,

    Mesochorus tipularius Gravenhorst, 1829, Ophion brevicornis Morley, 1915, and Plectochorus

    iwatensis (Uchida, 1928). Also the gasteruptiid Gasteruption opacum (Tournier,

    1877) is reported new to Sweden based on a record from inventory by NJ in 2013. This

    demonstrates how the knowledge of Swedish biodiversity can be substantially augmented

    by a short and intensive collecting expedition. We strongly recommend that other places in

    the country be subjected to similar efforts.

    Taxonomy of some European species of Mesochorus, including three new species from Finland and Sweden (Hymenoptera: Ichneumonidae: Mesochorinae)2017In: w-album, ISSN ISSN 1795-665X, Vol. 20, p. 3-42Article, book review (Refereed)
    Abstract [en]

    Redescriptions of the following seven species are made: Mesochorus gemellus Holmgren, 1860, M. tachypus Holmgren,

    1860, M. diversicolor Viereck, 1912, M. brevicollis Thomson, 1886, M. giberius (Thunberg, 1822), M. marginatus Thomson, 1886,

    and M. tetricus Holmgren, 1860. Three new species are described: M. marginatoides Vikberg sp. n. from Finland and Sweden, M.

    skanensis Vikberg sp. n. from Sweden, and M. ranini Vikberg sp. n. from Finland. The female of M. plumosus Dasch, 1971 is

    described from Finland (this species is known earlier only from N. America). A key to females of the eleven studied European

    species of Mesochorus is included.

    The following formal nomenclatural acts or changes are made: lectotypes are designated for Mesochorus tachypus Holmgren, 1860

    and for M. tetricus Holmgren, 1860. Mesochorus tachypus Holmgren, 1860, stat. n. (= M. macrurus Thomson, 1886, syn. n.), M.

    diversicolor Viereck, 1912, stat. n., M. brevicollis Thomson, 1886, stat. n., M. marginatus Thomson, 1886, stat. n., and M. tetricus

    Holmgren, 1860 (= M. curvicauda Thomson, 1886, syn. n.).

    Many females of M. tachypus and M. tetricus were found near the ground in the spruce forests in Janakkala, South Finland very

    late in the season (from October to December in 2011-2016). M. cimbicis (Ratzeburg, 1844) has been reared from cocoons of

    Trichiosoma sp. (scalesii Leach aggregate) and T. nanae Vikberg & Viitasaari in Finland. The correct primary host of Mesochorus

    bipartitus Schwenke, 1999 is Lygus rugulipennis Poppius (Hemiptera: Miridae).

    Abstract [en]

    We provide morphological egg data of 26 species of 5 chalcidoid families associated with cynipid galls(Hymenoptera: Cynipidae) from western Palaearctic, including the first egg data for the family Ormyridae. Adultchalcidoid species were reared from galls, and eggs obtained from dissected female ovaries were examinedusing scanning electron microscopy (SEM). The shape of the eggs varies from oval to elongate and taperedat both ends. Eggs of Eurytomidae as well as some Eulophidae, Eupelmidae and Pteromalidae are equippedwith a peduncle at the anterior end. We found a positive correlation between long eggs and long ovipositorsand confirmed the expectation that eggs of endoparasitoids are generally shorter and narrower than eggs ofectoparasitoids. We were able to locate the sperm entrance or micropyle at the anterior pole of eggs of severalspecies. It is situated at the anterior end of the egg and at the end of the peduncle when present. In addition,the eggshells of the endoparasitoid Sycophila biguttata (Swederus, 1795) (Hymenoptera: Eurytomidae) andthe ectoparasitoid Cecidostiba fungosa (Geoffroy, 1785) (Hymenoptera: Pteromalidae), are for the first timedescribed.
