    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.

    Redescription of Ganaspis brasiliensis (Ihering, 1905), new combiantion, (Hymenoptera: Figitidae) a natural enemy of the invasive Drosophila suzukii (Matsumura, 1931) (Diptera: Drosophilidae)2016In: Proceedings of the Entomological Society of Washington, ISSN 0013-8797, Vol. 118, no 1, p. 1-13Article in journal (Refereed)
    Abstract [en]

    The new combination of Ganaspis brasiliensis (Ihering, 1905) is proposed, and the species is redescribed from historical specimens taken in the Neotropical Region as well as more recent specimens reared from Drosophila suzukii Matsumura, 1931 in South Korea. Drosophila suzukii, otherwise known as the spotted-wing Drosophila, is a major pest of soft fruits the world over, and the search for effective natural enemies of this fly are ongoing. Though not parasitoids of D. suzukii, we also propose the following new combinations: Dieucoila brasiliensis (Kieffer, 1909), new combination, and Dieucoila brasiliana (Weld, 1952), new combination. After summarizing all known species of Eucoilinae with the specific epithet ‘brasiliensis’, we encourage future researchers to avoid this name in order prevent nomenclatural confusion.

    The description of Garudella Buffington and Forshage, new genus (Hymenoptera: Figitidae: Eucoilinae)2014In: Proceedings of the Entomological Society of Washington, ISSN 0013-8797, Vol. 116, no 3, p. 225-242Article in journal (Refereed)
    Abstract [en]

    Garudella, a remarkable new genus of eucoiline wasp is described from Thailand, Laos, and the Republic of Congo. Four new species of Garudella are described as well: G. acothonaspis, G. afrotropica, G. algo, and G. alicae. Several autapomorphies distinguish this genus from other eucoiline genera: a distinctly protracted and broadened pronotal plate; a massive, posteriorly protruding prop- odeum; reduced posterior rim of metapleuron; reduced scutellar foveae and lack of lateral bar “windows”; and a generally reduced scutellar plate. In addition, the posterior of the head has a distinctly curved occipital impression, resulting in the cuticle surrounding the foramen magnum to be extruded into a neck-like process. The biology of Garudella is unknown, but based on phylogenetic inference from morphology, the presumed host could be a cyclorrhaphous Diptera in a saprophagous environment.

    A Revision of Zaeucoila Ashmead (Hymenoptera, Figitidae), Parasitoids of Agromyzidae (Diptera): New Species, Identity, Distribution, and Hosts2017In: Proceedings of the Entomological Society of Washington, ISSN 0013-8797, Vol. 119, no 3, p. 317-397Article in journal (Refereed)
    Abstract [en]

    The eucoiline genus Zaeucoila Ashmead is revised. Following a re- evaluation combining previously published phylogenetic data and new specimens, Agrostocynips D ́ıaz is synonymized with Zaeucoila. All species included in Zaeucoila are systematically treated, and now amounts to twelve, seven of which are described as new here: Zaeucoila bitiburculata new species, Z. fidalgoii new species, Z. infuscata new species, Z. johnsonii new species, Z. lignys new species, Z. normae new species, Z. patera new species. The following new combinations are proposed and species redescribed: Zaeucoila grenadensis (Ashmead), new combination; Z. robusta (Ashmead), new combination; Z. flavipes (Ashmead), new combination. Agrostocynips diastrophi (Ashmead), Agrostocynips clavatus D ́ıaz, and Agrostocynips enneatoma (D ́ıaz) are new synonyms of Zaeucoila robusta. Zaeucoila incompleta (Kieffer), Z. triangu- lifera Kieffer, and Z. unicarinata Ashmead are redescribed. Zaeucoila is an unusual genus of Zaeucoilini in its wide distribution area: it can be found from southern Argentina well into the eastern United States and southern Canada; no other zaeucoiline genus shows such a pattern. Host records and geographic data for Zaeucoila are brought up to date, as well as a key to species. Zeucoila are primary parasitoids of Agromyzidae, including Liriomyza trifolii and other species that are notable economic pests of agriculture. Tropideucoila fulvonotata (Kieffer) is transferred to Marthiella (new combination).

    Abstract [en]

    The West Palearctic species of Rhoptromeris are revised. A total of 11 species are recognised as valid in this region, including four newly described species: Rhoptromeris dichromata sp. nov., Rhoptromeris koponeni sp. nov., Rhoptromeris leptocornis sp. nov. and Rhoptromeris macaronesiensis sp. nov. Eucoila luteicornis Ionescu, 1959 is synonymised with Rhoptromeris heptoma (Hartig, 1840) syn. nov. A checklist of the Holarctic Rhoptromeris is presented and an identification key to the West Palearctic species is provided.

    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.

    Varför var de gamla entomologerna swedenborgare?2017In: Entomologisk Tidskrift, ISSN 0013-886X, Vol. 138, no 2, p. 109-130Article in journal (Refereed)
    Abstract [en]

    In the decades surrounding the turn of the century 1800, several of the leading entomolo- gists in Sweden were also involved in Christian sects following the doctrines of Emanuel Swedenborg. This has often been noted by historians, but only occasionally by entomolo- gists, and has never been subjected to closer study.

    This paper sketches the history of Swedenborgian entomology in Sweden, from natural history students in Skara in the 1780s, over the utopian plans connected with the Swedish involvement in the colonial adventure in West Africa, to the Linnaean and Swedenborgian societies in Gotland and Stockholm, the coleopterist stronghold on the plain of Västergöt- land, and eventually to a last survivor in Fåhraeus’s old days.

    The two early key figures both came from Västergötland, Adam Afzelius and Leonard Gyllenhal. In the African adventure, the naturalists inspired by Swedenborg were Afzelius and Anders Sparrman. Gotland became a stronghold where Pehr Hemming Odhner and Gustaf J Billberg tutored Olof I Fåhraeus. In the Swedenborgian circles in Stockholm, Billberg, Carl Johan Schönherr and Carl E Deléen were prominent. Then Gyllenhal and Schönherr were both in Västergötland and Fåhraeus in Göteborg. Short biographies of these persons are given and their interconnections laid out.

    The Linnaean perspective on nature had one of its cornerstone in a religious sense of wonder when facing nature, which is known as physico-theology. In the generation after Linnaeus, some prominent naturalists turned away from wonder and speculation, in paral- lel with ongoing enlightenment campaigns against superstition. Especially in the tradi- tional academic natural history environments in Uppsala and Lund there was a reaction with many people turning to the new ideas of ”romantic biology” or ”Naturphilosophie” in Oken’s sense. Whereas in the non-academy-based, more bourgeois and amateur, natural history circles in Stockholm, in Västergötland and eventually in Göteborg, the maintaining of the sense of wonder in Linnaeanism seems to have fit better with the Swedenborgian movement and Swedenborg’s ideas

    Checklist of British and Irish Hymenoptera - Cynipoidea.2017In: Biodiversity data journal, ISSN 1314-2828, no 5, article id e8049Article in journal (Refereed)
    Abstract [en]

    BACKGROUND: The British and Irish checklist of Cynipoidea is revised, considerably updating the last complete checklist published in 1978. Disregarding uncertain identifications, 220 species are now known from Britain and Ireland, comprising 91 Cynipidae (including two established non-natives), 127 Figitidae and two Ibaliidae.

    NEW INFORMATION: One replacement name is proposed, Kleidotoma thomsoni Forshage, for the secondary homonym Kleidotoma tetratoma Thomson, 1861 (nec K. tetratoma (Hartig, 1841)).

    Description of the aberrant Leptopilina lasallei n. sp., with an updated phylogeny of Leptopilina Förster (Hymenoptera: Figitidae: Eucoilinae)2020In: Journal of Natural History, ISSN 0022-2933, E-ISSN 1464-5262, Vol. 54, p. 565-583Article in journal (Refereed)
    Abstract [en]

    In the search for native Asian parasitoids of Drosophila suzukii, the notorious spotted-wing Drosophila (SWD), an odd new species of Eucoilinae was discovered. Leptopilina lasallei sp. nov. is herein described and diagnosed relative to other eucoilines associated with drosophilid hosts. Morphologically, L. lasallei is somewhat aberrant within Leptopilina; phylogenetically, L. lasallei is sister group to the core Leptopilina. In the process of investigating L. lasallei, a de novo molecular phylogeny of Leptopilina was generated and is included here. The integrated approach used for the characterisation of L. lasallei, and the resulting phylogeny of Leptopilina, produced data useful to select parasitoid species for SWD biological control.

    World Cynipoidea (Hymenoptera): A Key to Higher- Level Groups2020In: Insect Systematics & Diversity, ISSN 2399-3421, Vol. 4, no 4, p. 1-69Article in journal (Refereed)
    Abstract [en]

    While much has been learned regarding the phylogeny and evolution of cynipoid wasps, clearly illustrated diagnostic tools and identification keys have remained stagnant. So too, where keys do exist, they are often to genus or species, and there are no user-friendly keys to groups such as tribes, subfamilies, or families. This state of affairs leaves a knowledge gap for non-specialists and slows future research on the group. To address this, we provide a fully illustrated key to the higher-level groups of world Cynipoidea. We also provide sum-maries of all higher-level taxa with updated generic lists, biological data, distribution, and literature resources. The dichotomous key presented here is complimented with a multi-entry matrix-based key, created in Lucid, and served on www.waspweb.org with online versions of the dichotomous keys also available.

    Abstract [en]

    The genus Platyceraphron Kieffer, 1906 with the species P. muscidarum Kieffer, 1906 is reported as new to Norway, caught in traps at two different locations. An old Swedish record which seems to have been forgotten is reviewed and one recent Swedish record added. No records are known from Finland and Denmark. Platyceraphron are remarkably dorsoventrally flattened wasps, and have been reported as parasitoids of subcorticeous flies, mainly Lonchaeidae.

    The identity of figitid parasitoids (Hymenoptera: Cynipoidea: Figitidae) of anthomyiid flies in conifer cones2018In: European Journal of Entomology, ISSN 1210-5759, E-ISSN 1802-8829, Vol. 115, p. 104-111Article in journal (Refereed)
    Abstract [en]

    Larvae of Strobilomyia flies (Diptera: Anthomyiidae) are serious pests in conifer-seed orchards because they feed on the seed inside the cones. Figitid parasitoids (Hymenoptera: Cynipoidea) of Strobilomyia larvae in conifer cones are commonly reported but under various generic names. It is argued here that, across the entire Holarctic region, these figitids belong to Amphithectus and perhaps also to Sarothrus (Figitinae), but not to Melanips (Aspicerinae), contrary to some reports. We conclude that the identity of the commonly found figitid associated with conifer cones (Larix and Picea) in Europe and Asia is Amphithectus austriacus (Tavares, 1928) comb. n. This is most likely considering the original description and the host association, although the type specimen of Seitneria austriaca Tavares, 1928 is lost. This species name takes priority over the recently described Amphithectus coriaceus Paretas-Martinez & Pujade-Villar, 2013. Seitneria Tavares, 1928 becomes a new junior synonym of Amphithectus Hartig, 1840, and Amphithectus coriaceus Paretas-Martinez & Pujade-Villar, 2013 becomes a new synonym of Amphithectus austriacus (Tavares, 1928) comb. n.

    Abstract [en]

    We present an updated catalog of North American Eucoilinae, bearing little resemblance to previous regional catalogs, which have been lagging behind in the recent systematic work in the group. The current catalog comprises 34 genera, arranged in six tribes. Of these genera, 9 are represented wholly by unidentified or undescribed species in the region, while the other 25 include 108 species recorded from the region. In comparison with previous catalogs, 24 genera and 41 species are added, and 34 species-level names are recombined, while 7 genera, five subgenera and 11 species are removed from the list of North American taxa. A modern, phylogenetically stable and type-based classification is implemented, as well as a tribal classification. In terms of nomenclatural acts, 25 new combinations are made (one is a reinstatement of an old combination); four new genus-levels synonymies are made (Tetramerocera Ashmead junior synonym of Ganaspis Fo ̈rster, Bewelda Quinlan and Aporeucoela Kieffer junior synonyms of Hexacola Fo ̈rster, Pentaplastidia Weld junior synonym of Trybliographa Fo ̈rster); eight new species-level synonymies are made; two species names are removed from synonymy; one new replacement name given (Hexacola pennsylvanicus for Hexacola subaperta Kieffer 1907 nec (Kieffer 1901a)).

    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.

    Structure of insect community in the fungus Inonotus radiatus in riparian boreal forests2016In: Journal of Natural History, ISSN 0022-2933, E-ISSN 1464-5262, Vol. 50, p. 1613-1631Article in journal (Refereed)
    Abstract [en]

    Basidiomes of polypore fungi host many insects. Yet systematic information about insect assemblages from most fungal species is lacking. We studied the insect community associated with the wood-decaying fungus Inonotus radiatus (Sowerby: Fr.) P. Karst. (Hymenochaetales). More specifically, we studied the effect of successional stage and weight of basidiomes, as well as shore exposition (north or south), on species richness and composition, as well as occurrence and abundance of the most abundant fungivores. Basidiomes were collected from riparian forests at five lakes in Sweden. Insects were reared out from the basidiomes in the laboratory. A total of 5645 adult insect individuals of 117 taxa were obtained. Among these, 2782 specimens of 36 taxa use Inonotus radiatus basidiomes as breeding habitat. Eight species of parasitic wasps were new to Sweden. The most abundant fungi- vore was Ennearthron cornutum (Ciidae), which is a generalist breeding in many polypore species. Based on our material and literature, the melandryid beetles Abdera affinis and A. flexuosa seem to be specialists on the order Hymenochaetales. Other fre- quent fungivores were Dorcatoma dresdensis (Ptinidae), and the lepidopterans Archinemapogon yildizae, Nemapogon cloacellus and N. picarellus (Tineidae). The parasitoid community associated with the tineid moths was similar to the community associated with the other polypore species in the order Polyporales. In contrast, the parasitoids associated with Dorcatoma (and/or Abdera) were dif- ferent from the other Polyporales species, suggesting that the fungal host species is more important for these parasitoid species than the beetle host species itself. The most abundant and fre- quent parasitoids were the braconids Diospilus dispar and Colastes fritzeni, which both parasitise Dorcatoma. Species richness was significantly smaller in fresh than in more decayed basidiomes, but species composition did not differ. There was no difference in species composition or richness between north and south shorelines.

    Saproxylic Hymenoptera in dead wood retained on clear cuts, relation to wood parameters and their degree of specialisation2023In: Journal of Insect Conservation, ISSN 1366-638X, E-ISSN 1572-9753, Vol. 27, no 2, p. 347-359Article in journal (Refereed)
    Abstract [en]

    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.

    The Swedish Malaise Trap Project: a 15 year retrospective on a countrywide inventory.2020In: Biodiversity Data Journal, ISSN 1314-2836, E-ISSN 1314-2828, Vol. 8, article id e47255Article in journal (Refereed)
    Abstract [en]

    The Swedish Malaise Trap Project (SMTP) is one of the most ambitious insect inventories ever attempted. The project was designed to target poorly known insect groups across a diverse range of habitats in Sweden. The field campaign involved the deployment of 73 Malaise traps at 55 localities across the country for three years (2003-2006). Over the past 15 years, the collected material has been hand sorted by trained technicians into over 300 taxonomic fractions suitable for expert attention. The resulting collection is a tremendous asset for entomologists around the world, especially as we now face a desperate need for baseline data to evaluate phenomena like insect decline and climate change. Here, we describe the history, organisation, methodology and logistics of the SMTP, focusing on the rationale for the decisions taken and the lessons learned along the way. The SMTP represents one of the early instances of community science applied to large-scale inventory work, with a heavy reliance on volunteers in both the field and the laboratory. We give estimates of both staff effort and volunteer effort involved. The project has been funded by the Swedish Taxonomy Initiative; in total, the inventory has cost less than 30 million SEK (approximately 3.1 million USD). Based on a subset of the samples, we characterise the size and taxonomic composition of the SMTP material. Several different extrapolation methods suggest that the material comprises around 20 million specimens in total. The material is dominated by Diptera (75% of the specimens) and Hymenoptera (15% of specimens). Amongst the Diptera, the dominant groups are Chironomidae (37% of specimens), Sciaridae (15%), Phoridae (13%), Cecidomyiidae (9.5%) and Mycetophilidae (9.4%). Within Hymenoptera, the major groups are Ichneumonidae (44% of specimens), Diaprioidea (19%), Braconidae (9.6%), Platygastroidea (8.5%) and Chalcidoidea (7.9%). The taxonomic composition varies with latitude and season. Several Diptera and Hymenoptera groups are more common in non-summer samples (collected from September to April) and in the North, while others show the opposite pattern. About 1% of the total material has been processed and identified by experts so far. This material represents over 4,000 species. One third of these had not been recorded from Sweden before and almost 700 of them are new to science. These results reveal the large amounts of taxonomic work still needed on Palaearctic insect faunas. Based on the SMTP experiences, we discuss aspects of planning and conducting future large-scale insect inventory projects using mainly traditional approaches in relation to more recent approaches that rely on molecular techniques.

    Fauna Europaea: Hymenoptera - Apocrita (excl. Ichneumonoidea).2015In: Biodiversity data journal, ISSN 1314-2828, no 3, article id e4186Article in journal (Refereed)
    Abstract [en]

    Fauna Europaea provides a public web-service with an index of scientific names (including important synonyms) of all living European land and freshwater animals, their geographical distribution at country level (up to the Urals, excluding the Caucasus region), and some additional information. The Fauna Europaea project covers about 230,000 taxonomic names, including 130,000 accepted species and 14,000 accepted subspecies. This represents a huge effort by more than 400 contributing specialists throughout Europe and is a unique (standard) reference suitable for many users in science, government, industry, nature conservation and education. Hymenoptera is one of the four largest orders of insects, with about 130,000 described species. In the Fauna Europaea database, 'Hymenoptera - Apocrita (excluding Ichneumonoidea)' comprises 13 superfamilies, 52 families, 91 subfamilies, 38 tribes and 13,211 species. The paper includes a complete list of taxa dealt with, the number of species in each and the name of the specialist responsible for data acquisition. As a general conclusion about the European fauna of Hymenoptera, the best known countries in terms of recorded species are those from northwestern Europe, with the least known fauna probably in the more eastern and southeastern parts of Europe.

    Dung beetles as drivers of ecosystem multifunctionality: Are response and effect traits interwoven?2017In: Science of the Total Environment, ISSN 0048-9697, E-ISSN 1879-1026, article id S0048-9697(17)32882-6Article in journal (Refereed)
    Abstract [en]

    Rapid biodiversity loss has emphasized the need to understand how biodiversity affects the provisioning of ecological functions. Of particular interest are species and communities with versatile impacts on multiple parts of the environment, linking processes in the biosphere, lithosphere, and atmosphere to human interests in the anthroposphere (in this case, cattle farming). In this study, we examine the role of a specific group of insects - beetles feeding on cattle dung - on multiple ecological functions spanning these spheres (dung removal, soil nutrient content and greenhouse gas emissions). We ask whether the same traits which make species prone to extinction (i.e. response traits) may also affect their functional efficiency (as effect traits). To establish the link between response and effect traits, we first evaluated whether two traits (body mass and nesting strategy, the latter categorized as tunnelers or dwellers) affected the probability of a species being threatened. We then tested for a relationship between these traits and ecosystem functioning. Across Scandinavian dung beetle species, 75% of tunnelers and 30% of dwellers are classified as threatened. Hence, nesting strategy significantly affects the probability of a species being threatened, and constitutes a response trait. Effect traits varied with the ecological function investigated: density-specific dung removal was influenced by both nesting strategy and body mass, whereas methane emissions varied with body mass and nutrient recycling with nesting strategy. Our findings suggest that among Scandinavian dung beetles, nesting strategy is both a response and an effect trait, with tunnelers being more efficient in providing several ecological functions and also being more sensitive to extinction. Consequently, functionally important tunneler species have suffered disproportionate declines, and species not threatened today may be at risk of becoming so in the near future. This linkage between effect and response traits aggravates the consequences of ongoing biodiversity loss.

    Completing Linnaeus’s inventory of the Swedish insect fauna: only 5,000 species left?2020In: PLOS ONE, E-ISSN 1932-6203, Vol. 15, no 3, article id e0228561Article in journal (Refereed)
    Abstract [en]

    Despite more than 250 years of taxonomic research, we still have only a vague idea about the true size and composition of the faunas and floras of the planet. Many biodiversity inventories provide limited insight because they focus on a small taxonomic subsample or a tiny geographic area. Here, we report on the size and composition of the Swedish insect fauna, thought to represent roughly half of the diversity of multicellular life in one of the largest European countries. Our results are based on more than a decade of data from the Swedish Taxonomy Initiative and its massive inventory of the country’s insect fauna, the Swedish Malaise Trap Project The fauna is considered one of the best known in the world, but the initiative has nevertheless revealed a surprising amount of hidden diversity: more than 3,000 new species (301 new to science) have been documented so far. Here, we use three independent methods to analyze the true size and composition of the fauna at the family or subfamily level: (1) assessments by experts who have been working on the most poorly known groups in the fauna; (2) estimates based on the proportion of new species discovered in the Malaise trap inventory; and (3) extrapolations based on species abundance and incidence data from the inventory. For the last method, we develop a new estimator, the combined non-parametric estimator, which we show is less sensitive to poor coverage of the species pool than other popular estimators. The three methods converge on similar estimates of the size and composition of the fauna, suggesting that it comprises around 33,000 species. Of those, 8,600 (26%) were unknown at the start of the inventory and 5,000 (15%) still await discovery. We analyze the taxonomic and ecological composition of the estimated fauna, and show that most of the new species belong to Hymenoptera and Diptera groups that are decomposers or parasitoids. Thus, current knowledge of the Swedish insect fauna is strongly biased taxonomically and ecologically, and we show that similar but even stronger biases have distorted our understanding of the fauna in the past. We analyze latitudinal gradients in the size and composition of known European insect faunas and show that several of the patterns contradict the Swedish data, presumably due to similar knowledge biases. Addressing these biases is critical in understanding insect biomes and the ecosystem services they provide. Our results emphasize the need to broaden the taxonomic scope of current insect monitoring efforts, a task that is all the more urgent as recent studies indicate a possible worldwide decline in insect faunas.

    Cleptes pallipes Lepeletier synonym of Cleptes semiauratus (Linnaeus) and description of Cleptes striatipleuris sp. nov. (Hymenoptera: Chrysididae, Cleptinae)2015In: Zootaxa, ISSN 1175-5326, E-ISSN 1175-5334, Vol. 4039, no 4, p. 543-52Article in journal (Refereed)
    Abstract [en]

    The interpretation of Linnaeus' name Sphex semiaurata Linnaeus, 1761 has been controversial. After type examinations, we conclude that it is identical with the common Cleptes pallipes Lepeletier, 1806 and thus re-establish the old synonymy: Cleptes semiauratus (Linnaeus, 1761) (=Cleptes pallipes Lepeletier, 1806, syn. reinst.). We have been unable to find an available name for the species with which it has been confused. In order to be able to designate a suitable type specimen, we prefer to describe it as a new species rather than suggest a replacement name: Cleptes striatipleuris Rosa, Forshage, Paukkunen & Soon sp. nov. (=Cleptes semiauratus sensu Lepeletier, 1806, nec Linnaeus, 1761; =C. splendens sensu Linsenmaier 1959, nec Fabricius, 1798).

    On the types of Bolboceratidae (Coleoptera: Scarabaeoidea) in the Swedish Museum of Natural History in Stockholm2023In: Zootaxa, ISSN 1175-5326, E-ISSN 1175-5334, Vol. 5301, no 4, p. 427-446Article in journal (Refereed)
    Abstract [en]

    The investigation of the Bolboceratidae collection of the Stockholm Museum of Natural History (NHRS) yielded 12 type specimens of eight Afrotropical and one Australian species. The majority of these types belongs to species described by Carl Henrik Boheman (1796–1868) based on specimens collected by Johan August Wahlberg (1810–1856) in southern Africa. In two of these species, we found ambiguity among potential syntypes. Therefore, based on comparison with original descriptions, we designate lectotypes for Bolboceras caffrum Boheman, 1857 and Bolboceras exasperans Péringuey, 1908, both of which are today classified in the genus Bolbocaffer Vulcano, Martínez & Pereira, 1969. Finally, we establish Bolboceras matabele Péringuey, 1908 (syn. nov.) as a junior subjective synonym of B. exasperans, we confirm a few synonymies that were historically established without study of type specimens, and we resurrect Bolboceras dorsuale Boheman, 1857 from previous synonymy under B. maculicolle Boheman, 1857 (Mimobolbus dorsualis (Boheman, 1857) n. comb. and stat. rev.).

    The "false Eucoila" finally named; Striatovertex a new genus of Eucoilinae (Hymenoptera, Cynipoidea, Figitidae)2011In: Zootaxa, ISSN 1175-5326, E-ISSN 1175-5334, Vol. 2811, p. 59-65Article in journal (Refereed)
    Abstract [en]

    The new genus Striatovertex is described to accomodate a distinct group of eucoiline wasps (Hymenoptera: Cynipoidea: Figitidae) currently included in the nominate genus Eucoila Westwood, but known among specialists to not belong there for decades. They are characteristically large wasps with reduced wing pubescence, parasitizing dung-breeding Diptera, and are common in North and South America, but also present in Australia and Hawaii. Their diagnostic characters place them in what is currently Ganaspini rather than very close to Eucoila in Eucoilini, and this has been confirmed by earlier phylogenetic analyses. Diagnostic and other distinctive characters are reviewed, and thirteen new combinations are made for species belonging to this group.

    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.

    Bird nest boxes infested with Carnus hemapterus (Diptera: Carnidae): A perfect arena for the study of trophic interplays with a special focus on parasitoid Hymenoptera2023In: European Journal of Entomology, ISSN 1210-5759, E-ISSN 1802-8829, Vol. 120, p. 129-136Article in journal (Refereed)
    Abstract [en]

    Birds' nests hold rich and diverse communities of invertebrates with complex interspecific interactions whose study could improve our understanding of food webs and resource dynamics. To reach this goal, identification of the participants of such interactions is basic but current knowledge on some key groups such as hymenopteran parasitoids is admittedly poor and unreliable. Here we describe the invertebrate fauna in nests of the Eurasian wryneck Jynx torquilla Linnaeus, 1758 (Piciformes: Picidae) and the relative importance of various trophic guilds. We found a rich community where ectoparasitic Diptera of birds, parasitoid wasps and scavenger Diptera had a prominent representation. We specifically studied the natural enemies of the most abundant bird ectoparasite Carnus hemapterus Nitzsch, 1818 (Diptera: Carnidae), which revealed that Kleidotoma caledonica Cameron, 1888 (Hymenoptera: Figitidae) is a specialized and frequent parasitoid of the ectoparasite. Information on the association between other parasitoid wasps, parasitoid flies and their hosts is also offered. Such associations could result in trophic cascades with remarkable consequences for the avian host.

    Abstract [en]

    The Afrotropical Cynipoidea are represented by 306 described species and 54 genera in four families: Cynipidae, Figitidae, Liopteridae and Ibaliidae, the latter represented by a single introduced species. Seven of these genera are only represented by undescribed species in the region. Seven new genus-level synonymies, one genus resurrected from synonymy, 54 new combinations, one combination reinstated, and one new replacement name are presented. We provide identification keys to the families, subfamilies and genera of cynipoid wasps occurring in the Afrotropical region (Africa south of the Sahara, including Madagascar and southern Arabian Peninsula). Online interactive Lucid Phoenix and Lucid matrix keys are available at: http://www.waspweb.org/Cynipoidea/Keys/index.htm. An overview of the biology and checklists of species for each genus are provided. This paper constitutes the first contributory chapter to the book on Afrotropical Hymenoptera.

    Review of Afrotropical Figitinae (Figitidae, Cynipoidea, Hymenoptera) with the first records of Neralsia and Lonchidia for the region.2014In: ZooKeys, ISSN 1313-2989, E-ISSN 1313-2970, no 453, p. 37-69Article in journal (Refereed)
    Abstract [en]

    The cynipoid subfamily Figitinae is poorly represented in the Afrotropical region with two genera (Figites Latreille and Xyalophora Kieffer) and six species currently known. Here we record an additional two genera (Neralsia Cameron and Lonchidia Thomson) for the region and describe three new species: Neralsiahaddocki sp. n.; Xyalophoratedjoansi sp. n.; Xyalophoratintini sp. n. Benoit's species described in 1956 are synonymized under Figitesaciculatus (Benoit, 1956): Figiteseffossus syn. n.; Figitesfavonius syn. n.; Figitesfurvus syn. n.; Figitesfraudator syn. n. Identification keys to the figitine genera and species occurring in the Afrotropical region are provided. Online interactive Lucid Phoenix and Lucid matrix keys are available at: http://www.waspweb.org/Cynipoidea/Keys/index.htm.
