In the past decade, several platygastroid biological control agents were found to be adventive in North America and Europe while under evaluation in quarantine. The scope and relative risk of this phenomenon is not fully known, but it is clearly a trend with implications for classical biological control. As a means of assessing the issue, and providing a global baseline, we implemented a data-mining approach with DNA sequences in the Barcode of Life Database, which yielded 201 platygastroid BINs with intercontinental and island distributions. At least fifty-five BINs displayed exact COI barcode matches across continents, with many more BINs being inconclusive due to sequence length variation. These intercontinental and island BINs include biocontrol agents known to be adventive and many species identified only to genus. We provide 2,500 identifications for platygastroid BOLD BINs, 88% to genus, to encourage additional research on this distributional phenomenon. The intercontinental BOLD BINs were compared to literature records and GBIF occurrences of cosmopolitan species to identify gaps and discordance across data sources. A small COI barcode dataset from localities in Florida and Germany, including topotypical specimens, revealed more intercontinental matches. To assess the scale of intercontinental distributions for host taxa, and to examine the scale for a broader range of taxa, we analyzed COI sequences in BOLD for the entirety of Insecta. The discovery that adventive parasitoids are following their invasive hosts has important implications for biosecurity and biological control and may lead to an increased emphasis on early detection.

A long tradition of separate Nearctic and Palaearctic taxonomic studies of the diverse aleocharine rove beetles (Coleoptera: Staphylinidae) has obscured the recognition of Holarctic species and detection of adventive species in both regions. Recently, integrated study of the two regions through detailed morphological comparisons and development of an authoritatively identified DNA barcode reference library has revealed the degree to which these two aleocharine faunas are interconnected, both naturally and through human activity. Here this approach is adopted to recognize new species, reveal Holarctic species, and recognize adventive species in both North America and Europe. The following new species are described: Isoglossa triangularis Klimaszewski, Brunke & Pentinsaari, sp. nov. from British Columbia; Gnypeta impressicollis Klimaszewski, Brunke & Pentinsaari, sp. nov., from Ontario, Maryland and North Carolina; Aloconota pseudogregaria Klimaszewski, Brunke & Pentinsaari, sp. nov., from Ontario and Virginia; and Philhygra pseudolaevicollis Klimaszewski, Brunke & Pentinsaari, sp. nov. from eastern Canada. Dasygnypeta velata and Philhygra angusticauda are revealed to be Holarctic species, resulting in the following synonymies: Dasygnypeta velata (Erichson, 1839) = Gnypeta minuta Klimaszewski & Webster, 2008, syn. nov. and Philhygra angusticauda (Bernhauer, 1909) = Atheta (Philhygra) pinegensis Muona, 1983, syn. nov. The Nearctic species Hylota ochracea (and genus Hylota), Thecturota tenuissima, and Trichiusa robustula are newly reported from the Palaearctic region as adventive, resulting in the following synonymies: Hylota ochracea Casey, 1906 = Stichoglossa (Dexiogyia) forticornis Strand, 1939, syn. nov.; Thecturota tenuissima Casey, 1893 = Atheta marchii Dodero, 1922, syn. nov.; and Trichiusa robustula Casey, 1893 = T. immigrata Lohse, 1984, syn. nov. The Palaearctic species Amarochara forticornis, Anomognathus cuspidatus, Oligota pumilio, and Parocyusa rubicunda are newly confirmed from the Nearctic region as adventive, resulting in the following synonymies: Parocyusa rubicunda (Erichson, 1837) = Chilopora americana Casey, 1906, syn. nov. and Anomognathus cuspidatus (Erichson, 1839) = Thectura americana Casey, 1893, syn. nov. The genus Dasygnypeta, sensu nov. is newly reported from North America, Paradilacra is newly reported from eastern North America, and Haploglossa is newly reported from Canada, resulting in the following synonymy: Paradilacra densissima (Bernhauer, 1909) = Gnypeta saccharina Klimaszewski & Webster, 2008, syn. nov. Native Cyphea wallisi is newly reported from across Canada and C. curtula is removed from the Nearctic fauna. The status of both Gyrophaena affinis and Homalota plana is uncertain but these species are no longer considered to be adventive in North America. Three new combinations are proposed: Dasygnypeta baranowskii (Klimaszewski, 2020) and D. nigrella (LeConte, 1863) (both from Gnypeta) and Mocyta scopula (Casey, 1893) (from Acrotona). Dolosota Casey, 1910, syn. nov. (type species Eurypronota scopula Casey), currently a subgenus of Acrotona, is therefore synonymized with Mocyta Mulsant & Rey, 1874. Additionally, four new Canadian records and 18 new provincial and state records are reported.

The Paititi Natural Reserve is located in the southeastern part of the Tandilia mountain range (Buenos Aires province,Argentina). With the aim of recording the floristic richness of Sierra Chica, an untouched area of the reserve, all vascularplants were inventoried and categorized by family, status, and life form. Altogether, 364 taxa from 72 familieswere found, with the most predominant families being Poaceae (20.7%), Asteraceae (20.1%), and Fabaceae (5.8%).We found 95 adventive species, 4 cosmopolitan, and 265 native. The most abundant life forms were hemicryptophytes(33.1%), therophytes (30.6%), and criptophytes (22.6%); the therophytes were mostly represented by adventive species.We also found species that were known from Buenos Aires province but not from mountainous areas. Despitebeing a small area within Argentina, Sierra Chica constitutes a valuable refuge for native flora of the Tandilia mountainrange system, which is in danger of being affected by exotic plants.

In the summer of 2010, two male specimens of the neotropical orchid bee genus Eufriesea Cockerell were collected in the Guadalupe Mountains of western Texas and southeastern New Mexico, USA. We tentatively identified them as E. coerulescens (Lepeletier de Saint Fargeau) because of the uncertainty surrounding the limits of this taxon and hypothesized that they were members of a persistent bee population, rather than long-distance transient vagrants. The goals of this paper are to clarify the identity of these specimens, assess the species limits of E. coerulescens, and to evaluate suitability of habitats in the USA for this adventive species. Herein, we revise the species in the coerulescens group using morphological features of both sexes and confirm that the specimens of Eufriesea from the USA are E. coerulescens. We recognize the following six species in the coerulescens group: E. coerulescens, E. micheneri Ayala & Engel, E. simillima (Moure & Michener), which is reinstated from synonym with E. coerulescens, and three new species from Mexico (E. barthelli Gonzalez & Griswold, sp. n., E. engeli Gonzalez & Griswold, sp. n., and E. oliveri Gonzalez & Griswold, sp. n.). To facilitate the identification of these taxa, we present a fully illustrated account of the species, comparative diagnoses, descriptions, and an updated key to all Mexican species of Eufriesea. Our analyses using species distribution modelling show an absence of suitable habitat for E. coerulescens in western Texas and southeastern New Mexico, thus favoring the long-distance dispersal hypothesis. The analyses also suggest high suitability of habitats across the Caribbean and some areas in Florida, as well as in other regions in Mexico and Central America. We discuss the implications of these results and compare them with the predicted distribution available for the other two known adventive orchid bee species in the USA.

Synopsis of adventive species of Coleoptera (Insecta) recorded from Canada. Part 5: Chrysomeloidea (Cerambycidae, Chrysomelidae, and Megalopodidae)

All 3,062 species of Coleoptera from 92 families known to occur in New Brunswick, Canada, are recorded, along with their author(s) and year of publication using the most recent classification framework. Adventive and Holarctic species are indicated. There are 366 adventive species in the province, 12.0% of the total fauna.

Phosphaenus hemipterus (Goeze) is a Palaearctic glow worm (Coleoptera: Lampyridae), previously been reported in North America on the basis of two specimens; one collected in 1947 in Yarmouth, Nova Scotia; the other in 1989 in Montreal, Quebec. The present study newly records it from three sites in Halifax, Nova Scotia. One hundred and twenty six adult males and larvae were collected in 2009 in disturbed urban grassland areas, similar to habitats in England and Belgium where the species has been investigated. Experiments confirm that larvae feed on earthworms (Lumbricus terrestris), consistent with observations in Europe. The habitat is described, including vegetation, potential predators, and prey. Although ballast-shipments have previously been proposed as a vector for the species' introduction to North America, the present study suggests that the importation of agricultural and horticultural products, which has lead to the introduction of many earthworms to the continent, could also serve as a conduit for the introduction of obligate earthworm predators such as the larvae of P. hemipterus. Although an adventive species, possible conservation concerns are discussed for a species that is considered endangered in parts of its native range.

New records of Histeridae from Atlantic Canada are reported. Three species are newly recorded from Prince Edward Island and two from New Brunswick, one of which, the introduced Palearctic Atholus bimaculatus (Linnaeus), is newly recorded from Atlantic Canada as a whole. These new records increase the known histerid fauna of the region to 37 species, 30 native and 7 introduced ones. The regional zoogeography of the Histeridae is examined focusing on differences between the faunal composition of the various provinces and the possible reasons responsible for these. The island faunas of Cape Breton, Prince Edward Island, and Newfoundland are examined. All have reduced faunas in comparison with the mainland perhaps as a result of island-associated diminutions, an area effect, a paucity of collecting, or a combination of these factors. Those of Cape Breton and Prince Edward Island are proportionately similar to those of other families of Coleoptera, whereas that of Newfoundland (only 10% of the mainland fauna) is significantly less, a circumstance which deserves further investigation. Seven species of introduced histerids have been recorded in the region. The average dates of first detection of these species are much later than the earliest records of these species in North America and comparatively later than is the case with other suites of introduced species in the Staphylinidae and Carabidae, perhaps as a result of the sparse attention the Histeridae have historically received by coleopterists in the region. Most of the introduced histerids are known to be synanthropic and may have been introduced to the region association with the importation of livestock and materials related to animal husbandry. The Histeridae of the region largely fall into one of several trophic guilds: coastal species and those associated with beach-drift material; species associated with bird nests; species associated with mammal nests; myrmecophilus species; saproxylic species found in sub-cortical environments; and generalist species found in a wide variety of decomposing situations.

Seven species of adventive Palaearctic staphylinids, Ilyobates bennetti Donisthorpe, Meotica exilis (Knoch), Meotica 'pallens' (Redtenbacher), Anotylus insecatus (Gravenhorst), Anotylus tetracarinatus Block, Oxytelus sculptus Gravenhorst, and Lathrobium fulvipenne (Gravenhorst) are newly recorded in the Maritime Provinces of Canada. One of these, M. exilis, a cosmopolitan species, is newly recorded in Canada and represents the first verifiable report of this species from North America. The history of M. exilis in North America is examined indicating that previous reports were the result of misidentification or of specimens of uncertain identity that can no longer be located. The confused nomenclature of this species is also discussed. The confused taxonomy of Meotica 'pallens' is discussed with regard to the identity of the species reported under this name in North America. Atheta dadopora Thomson is newly recorded in Prince Edward Island. Records are provided that establish the presence of L. fulvipenne in North America in five Canadian provinces. Observations on A. insecatus in the field establish that they are predators of dipteran larvae. New early dates of detection are reported for Quedius curtipennis Bernhauer, Tasgius ater (Gravenhorst), Philonthus cognatus Stephens, and Philonthus rectangulus Sharp. As a consequence, 87 species of adventive Staphylinidae are now known to occur in the Maritime Provinces, 76 of which have been recorded in Nova Scotia, 61 in New Brunswick, and 29 on Prince Edward Island. The staphylinid fauna is briefl y discussed in relation to its zoogeographic components and its regional composition.

The last complete checklist of the British and Irish Hymenoptera was that of Fitton et al. (1978). Much has changed in the intervening 36 years, including many changes to the higher classification of Hymenoptera and, of course, the discovery of many additional species. In producing this checklist we (the authors of the various chapters) have tried to provide a useful entry to the literature dealing with the identification and classification of the species involved, particularly for the less familiar parasitoid groups. The checklist also begins the process of summarising data on species' distribution on a country-level basis. I hope that this will serve to stimulate increased interest in this relatively neglected part of the British and Irish fauna. This volume serves as a standard reference point for the British and Irish Hymenoptera fauna, and, hopefully, provides a backbone to recording efforts and the underlying taxonomy. Having an endpoint to this project has stimulated much research in to our fauna, including the critical examination of museum collections, and thus pushed some checklist sections to a state they might not otherwise have reached. Of course, a checklist is never finished. The next incarnation will be digital, and the checklist is already in the process of migrating to a Scratchpad (Hymenoptera of the British Isles), where updates will be maintained as and when changes occur. Criteria for inclusion Additions to the British and Irish list since Fitton et al. (1978) are referenced (with a note 'added by...'). Species have been included that have not previously been formally published as being British or Irish but which are represented by reliably identified specimens in collections. For these species, collection depositories are listed so that the specimens can be traced. Known introductions, occasional or otherwise, including those species that are only able to sustain populations indoors, are also included, but noted as introduced. However, introduced or adventive species are not included in the counts of valid British and Irish species (Table ​(Table11). Table 1. Classification of Hymenoptera adopted in this checklist, with numbers of confirmed British and Irish species in the 1978 and current checklists (not including known introductions that have failed to establish in the wild). Note that the spelling of Trigonalidae and Trigonaloidea, as opposed to 'Trigonalyidae', follows Aguiar et al. (2013).

For the first time for the flora of Uzbekistan is a species of adventive Duchesnea indica . This plant has recently been found in the surroundings of the city of Tashkent as a fugitive from the culture and the territory of the Bukhara oasis as an introduction. Based on the literature data and herbarium materials, we demonstrated that this plant has not been identified as a member for adventive flora of the region previously. Currently, D. indica in Tashkent is widespread and actively spreading. In the flora of Bukhara and its suburbs, D. indica originated as an adventive species under the influence of anthropogenic factors. This species is often found in buildings around the city, near the lawns and in flower beds. The place of origin of the D. indica is areas of South, Southeast and East Asia, with a mild and damp climate. Since the 19th century, is cultivated in Central Europe as an ornamental plant. In recent decades there has been a spontaneous and active dissemination of this species on every continent except Antarctica. Concerning the settling time is eukenophytes D. indica , according to the method of skidding – ergaziophytes, and on the degree of naturalization – epekophytes.

The Aleocharinae (Coleoptera: Staphylinidae) of Ontario were reviewed in the context of recently studied material, primarily from insect surveys conducted by the University of Guelph Insect Collection (Ontario, Canada). Aleochara daviesi Klimaszewski & Brunke sp. n., Agaricomorpha websteri Klimaszewski & Brunke sp. n., Atheta (Microdota) alesi Klimaszewski & Brunke sp. n., Dinaraea backusensis Klimaszewski & Brunke sp. n., and Strigota obscurata Klimaszewski & Brunke sp. n. are described as new to science. We also report 47 new Ontario records and 24 new Canadian records. Callicerus rigidicornis (Erichson) and Alevonota gracilenta (Erichson) are newly reported from North America as adventive species. A checklist, with Canadian distributions by province, of the 224 species of Aleocharinae known from Ontario is given. The following species are placed in subjective synonymy with Dexiogyia angustiventris (Casey): (De. asperata (Casey) syn. n., De. abscissa (Casey) syn. n., De. tenuicauda (Casey) syn. n., De. intenta (Casey) syn. n., De. alticola (Casey) syn. n.). The following species are placed in subjective synonymy with Acrotona subpygmaea (Bernhauer): (Ac. avia (Casey) syn. n., Ac. puritana (Casey) syn. n.). Lectotypes are designated for Thiasophila angustiventris Casey, Th. asperata Casey, Ischnoglossa intenta Casey, Oxypoda rubescans Casey, Chilopora americana Casey, Chilopora fuliginosa Casey, Coprothassa smithi Casey, Atheta subpygmaea Bernhauer, Colpodota puritana Casey, Strigota seducens Casey, Trichiusa compacta Casey, Trichiusa hirsuta Casey and Trichiusa robustula Casey.

The adventive rove beetle, Quedius cinctus (Paykull) is recorded for the first time in Canada. This discovery provides an opportunity to briefly survey the distribution and early dates of detection of the seven adventive species in the genus Quedius Stephens in North America.

Background Megachile (Callomegachile) sculpturalis Smith, the giant resin bee, is an adventive species in the United States. First established in the United States during the early 1990s, records currently exist from most states east of the Mississippi River along with Iowa and Kansas. New information New distributional records are presented for Megachile (Callomegachile) sculpturalis Smith, an introduced bee. Additional records presented here expand the known distribution southwest through Arkansas, Louisiana, Mississippi, Missouri, and Texas. An updated host plant list containing new records is also presented, expanding the number of known floral associations.
