Tidskriftsartikel (populärvet., debatt m.m.)abstract
- We describe the work with donated insect collections at the Swedish Museum of NaturalHistory (NRM) in Stockholm, Sweden. The museum receives donations yearly fromamateur entomologists, and they are an important contribution to the enrichment of thecollections. For the collector it is satisfying that a public institution takes on the long termresponsibility of safeguarding the scientific value in a collection, curating and making itavailable 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 collectionare unfortunately not matched by staff funding, and as at other European museumsvolunteer work constitute vital and invaluable help. We acknowledge especially some ofthe volunteer work in the Coleoptera and Hymenoptera collections. Recently we have engagedwith amateur entomologists by organizing taxon-specific workshops at the museumwhich has stimulated exchange and collaboration. The Hymenoptera-day was visited by 30participants, and the Diptera-meeting by 49. As an example of what happens with a donationonce it reaches the museum, we describe the work with a recent Coleoptera collectiondonation by Jan Olsson, Vallentuna. A few highlights from the unidentified material,including the Archostematan beetle Priacma serrata (Cupedidae) and the false jewelbeetleSchizopus 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 presentingdigitized material in Swedish natural history collections. Both metadata on specimens andphotos are made searchable here. We also launch a new webpage at www.nrm.se/insektsdonationerwhere we write about new donations to the Entomology collections, with JanOlsson’s Coleoptera collection first out.

Tidskriftsartikel (populärvet., debatt m.m.)abstract
- 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. Vi vill medden här artikeln dels informera om föreningenoch uppmuntra till medlemsskap, dels beskrivaföreningens koppling till svensk entomologi ochsärskilt Renè Malaise.

Tidskriftsartikel (refereegranskat)abstract
- 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.

- 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.

Tidskriftsartikel (refereegranskat)abstract
- 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.

Tidskriftsartikel (refereegranskat)abstract
- Intensive forestry is a threat to biodiversity, and therefore actions are made to mitigate this loss. The actions are, however, designed based on available knowledge about the requirements of species, and for saproxylic insects this concerns mainly Coleoptera, while the diverse but poorly known Hymenoptera has contributed less. In this paper we therefore asked whether the substrate requirements of Hymenoptera (divided as parasitoids and non-parasitoids) are similar to those of Coleoptera and Diptera. We used an insect material reared from logging residue wood for the comparison. Theoretically parasitoid Hyme- noptera should be less specialised than Coleoptera and other host species as they belong to a higher trophic level. However, we found no such difference and even an opposite trend, that parasitoids were more specialised than beetles. Parasitoids had significantly more species in newly dead wood of fine diameter (1–4 cm, compared to coarse wood of 8–15 cm) compared to other groups. This is probably due to that many of them have bark beetles as hosts. The non-parasitoids were less specialised than the other groups and more confined to old wood (4–5 years), which is in line with that many of them are aculeate wasps building nests in emergence holes from other insects.Implications for insect conservation The habitat requirements of Hymenoptera suggest that the conservation actions designed for the well known groups are also applicable for them. The parasitoids’ association to trivial substrates (fine wood) sug- gest a good supply of breeding habitat, whereas their high specialisation in combination with higher trophic level suggest they contain an even higher proportion of threatened species than Coleoptera. How this is traded off needs further studies.

An interactive key to the European genera of Campopleginae (Hymenoptera, Ichneumonidae) and 20 new species for Sweden
- 2022
-
Ingår i: Entomologisk Tidskrift. - Björnlunda, Sweden. - 0013-886X. ; 143, s. 121-156
-
Tidskriftsartikel (refereegranskat)abstract
- Darwin wasps of the subfamily Campopleginae are among the most poorly studied insect groups, which is to a large part due to inadequate identification tools. The currently 835 European species are classified into 42 genera, some of a somewhat unclear delimitation, and are very hard to identify using the incomplete, scattered and often poorly illustrated literature. We here assess different character systems for genus identification and provide an interactive, dynamic online key to the European genera. We apply this key to identify 3,500 specimens of the Swedish Malaise Trap Project to genus level. We then chose ten comparatively small genera for species-level identification, reporting a total of 37 species, 20 of which are new records for Sweden. The large number of species only found in a single trap location indicates that a lot remains to be discovered, even in an otherwise well-known fauna such as Sweden’s.

Tidskriftsartikel (refereegranskat)abstract
- 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).

- 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 mandibularisFabricius, 1804 (Tenthredinidae). The problematic taxonomic status of Arge annulata isdiscussed, and it is recorded for the first time from Germany and Estonia. For Heptamelusdahlbomi (Thomson, 1870) (Heptamelidae): a lectotype is designated for Caenoneuradahlbomi, H. ussuriensis Malaise, 1931 is placed as its junior synonym, Athyrium distentifoliumrecorded as a new host, and additional distribution data are presented, including thefirst records from Austria. A lectotype is designated for Heptamelus magnocularis Malaise,1931, and this species briefly compared with H. dahlbomi.

North European gall-inducing Euura sawflies (Hymenoptera, Tenthredinidae, Nematinae)
- 2017
-
Ingår i: Zootaxa. - Auckland, New Zealand : Magnolia Press. - 1175-5326 .- 1175-5334. ; 4302, s. 1-115

Recension (refereegranskat)abstract
- 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. bigallae, E. 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.

Tidskriftsartikel (refereegranskat)abstract
- 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.

Open access in a taxonomic sense: a morphological and molecular guide to Western Palaearctic Dusona (Hymenoptera, Ichneumonidae)

Tidskriftsartikel (refereegranskat)abstract
- 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 exam- ined 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 sev- eral 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.

Tidskriftsartikel (populärvet., debatt m.m.)abstract
- Johannesörter Hypericum spp. är ett släkte med sju arter i Sverige. De känns igen på de gula femtaliga blommorna med många ståndare. Fem av arterna är antingen sällsynta eller väldigt lokalt förekommande. Man syftar därför främst på de två vanliga arterna äkta johannesört H. perforatum och fyrkantig johannesört H.maculatum när man pratar om demsom värdväxter för insekter. Dessatvå arter förekommer i liknande biotoper, främst på torra till medelfuktiga gräsmarker och ruderatmarker. De kan förekomma i stor mängd på igenväxningsmarker. Fyrkantig johannesört finns generellt på lite fuktigare marker och längre norrut än äkta johannesört. Johannesörthar också kallats mannablod eftersom krossade blomknoppar ger enblodröd färg.

The genera of Nematinae (Hymenoptera, Tenthredinidae)
- 2014
-
Ingår i: Journal of Hymenoptera Research. - Sofia, Bulgaria : Pensoft Publishers. - 1314-2607. ; 40, s. 1-69
-
Tidskriftsartikel (refereegranskat)abstract
- 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.

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

- 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 wasps

- 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.

Recension (refereegranskat)abstract
- Stora Karlsö is a small island close to Gotland in the Baltic Sea of which the Hymenopteranfauna has not been extensively studied before. In August 2014, a team of eight personscarried out an inventory of Hymenoptera, mainly the parasitoid wasps and sawflies, onthe island. Sampling was done with Malaise traps for a period of 22 days, complementedwith vegetation sweeping, branch shaking and opportunistic handpicking during a five daysojourn. As a result, about 200 species of parasitoid wasps and 14 sawflies are reported forStora Karlsö for the first time. Eleven species are reported as new to Sweden: The sawflyAthalia cornubiae Benson, 1931, the gasteruptiid Gasteruption opacum (Tournier, 1877),the diapriid Spilomicrus rufitarsis (Kieffer, 1911), the eulophid Entedonomphale bulgaricaBoyadzhiev & Triapitsyn, 2007, the braconids Bracon rozneri Papp, 1998 and Gnamptodondecoris (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 Plectochorusiwatensis (Uchida, 1928). Also the gasteruptiid Gasteruption opacum (Tournier,1877) is reported new to Sweden based on a record from inventory by NJ in 2013. Thisdemonstrates how the knowledge of Swedish biodiversity can be substantially augmentedby a short and intensive collecting expedition. We strongly recommend that other places inthe country be subjected to similar efforts.

- A new genus and species of Stereomerini, Cheleion malayanum gen. n. and sp. n., are described based on a single specimen from the Malacca peninsula in Malaysia. It is the first stereomerine found on the mainland of the Asian continent. A key to genera of Stereomerini and a phylogenetic estimate of the steteomerines using 24 species representing 7 tribes of Aphodiinae based on 53 morphological characters. The phylogenetic analysis places the new species within the tribe Stereomerini as a sister to the monophyletic group including Adebrattia, Austaloxenella, Bruneixenus, Pseudostereomera and Stereomera. A survey is given of the various taxa of Aphodiinae that are termite and/or ant inquilines, or have been presumed to be so based on morphology, and their phylogeny is discussed.

From Parasitoids to Gall Inducers and Inquilines : Morphological Evolution in Cynipoid Wasps
- 2004
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- One of the large lineages of parasitic wasps, the Cynipoidea, exhibits three distinctly different life modes. Slightly more than half of the about 3000 species are parasitoids in insect larvae, whereas the remaining species are associated with plants, either as gall inducers or as inquilines (guests feeding on plant tissue in galls). The main focus of this thesis has been to identify morphological changes associated with the shifts between life modes. Particular attention was paid to structures believed to be important in gall initiation. Comparative anatomical studies of the egg, larva and venom apparatus were performed, including representatives of parasitoids, gall inducers and inquilines. Examination of gross morphology and ultrastructure revealed that the eggs of the gall inducers are larger and surrounded by a thicker shell than the parasitoid eggs. These differences may be related to the fact that the gall inducer egg contains sufficient egg yolk for the embryo during the entire egg period, whereas the parasitoid egg often absorbs nutrients through the eggshell. Furthermore, the gall inducer egg is probably more exposed to desiccation and therefore a thicker and more resistant eggshell is crucial. Comparing the terminal-instar larvae of about 30 species of parasitoids, gall inducers and inquilines, extensive morphological variation was found, particularly in the head and mouthpart features. The variation was summarized in 33 morphological and one life-history character and parsimony analyses were performed. The resulting phylogenetic estimates were largely in accordance with previous analyses of adult morphology and molecular data. The larval data point to a single origin of the inquilines, in agreement with adult morphology but in conflict with molecular data. The venom apparatus was found to be quite uniform in structure among a sample of 25 species of cynipoid species. It consists of a very short venom duct, a reservoir and a single unbranched venom gland. With few exceptions, the venom apparatus is conspicuously larger relative to the female metasoma in the gall inhabiting species than in the parasitoids. We found little evidence of anatomical structures that could facilitate chemical communication between the gall-inducer embryo and the surrounding plant tissue through the thick eggshell. On the other hand, the enormous venom glands and reservoirs, which are apparently not used for defence, suggest that the adult female plays a significant role in gall induction by injecting secretions into the host plant when laying eggs.

Morphology and evolution of the cynipoid egg (Hymenoptera)

Tidskriftsartikel (refereegranskat)abstract
- We describe gross egg morphology and provide the first data on eggshell ultrastructure in cynipoids (Hymenoptera) based on species representing three distinctly different life histories: internal parasitoids of endopterygote larvae, gall inducers and phytophagous inquilines (guests in galls). We then use existing phylogenetic hypotheses to identify putative changes in egg structure associated with evolutionary life-history transitions. We find four major structural changes associated with the shift from parasitoids laying their eggs inside a host larva to gall inducers laying their eggs in or on plants: (1) from a narrow and gradually tapering gross form to a distinct division into a stout body and a long and thin stalk; (2) from a thin to a thick eggshell; (3) from a flexible to a rigid endochorion; and (4) from crystal bundles with shifting orientation in the exochorion to layers of parallel crystal rods. By contrast, we find no major changes in egg structure associated with the transition from gall inducers to inquilines. Comparison between pre- and post-oviposition eggs of one gall inducer and one inquiline suggests that mechanical stress during the passage through the egg canal gives rise to numerous tiny stress fractures in the boundary separating the exo- and endochorion. In one of the gall inducers, Diplolepis rosae, that end of the egg, which is inserted into the plant, has a specialized and apparently porous shell that may permit chemical exchange between the embryo and the plant. Other structures that could facilitate chemical communication with the host plant through the eggshell were, however, not observed in the eggs of gall inhabitants.

- 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.

- In the autumn of 2006 the large insect collection of Lars Huggert (1942–2003) was kindly donated to the Swedish Museum of Natural History in Stockholm by the siblings of the collector. A first assessment of the size of the collection, estimated more than 30 000 specimens of Coleoptera, 23 000 specimens of Hymenoptera and about 2 000 specimens of Diptera. Here an inventory of the Hymenoptera part of the Lars Huggert donation is given including an account of type specimens of 32 taxa described by Huggert and currently housed in NHRS. Specimens of more than 1 330 species of Hymenoptera were included in the donation which enriched the existing NHRS collections immensely. Huggert described 80 species and 34 genera/subgenera in the families Diapriidae Haliday, 1833, Platygastridae Haliday, 1833, Scelionidae, Haliday 1839 and Pteromalidae Dalman, 1820 and these families are particularly well-represented in the donation.

Venom gland and reservoir morphology in cynipoid wasps

Tidskriftsartikel (refereegranskat)abstract
- The venom apparatus morphology was examined in 25 species of Cynipoidea, representing 11 parasitoid taxa; 12 gall inducers and two inquilines. Typically the venom apparatus consists of an oval or bilobed reservoir connected to the ovipositor apparatus by a very short venom duct at the anterior end and to a single elongate unbranched venom gland at or near its posterior end. The Dufour's gland was not found in any of the examined species. The elongate unbranched venom gland and the absence of the Dufour's gland are putative cynipoid synapomorphies. The shape and size of especially the venom reservoir were found to vary considerably within the Cynipoidea. It is typically less prominent in the parasitoid taxa than in the gall inducers. Exceptions include the poppy gallers Barbotinia and Aylax, in which the venom reservoirs were remarkably small and in the rose galler Diplolepis, where only a rudimentary venom apparatus was found. Possible functional and phylogenetic implications of cynipoid venom apparatus features are discussed.
