The Elateridae in the Maritime Provinces of Canada is surveyed. One hundred and twenty-five species have been recorded, 110 in Nova Scotia, 98 in New Brunswick, and 48 on Prince Edward Island. Of these, 117 are Nearctic, four are Holarctic, and four are introduced Palaearctic species. Twenty-four species are newly recorded in Nova Scotia, 13 in New Brunswick, and 27 on Prince Edward Island, for a total of 64 new provincial records. Fourteen species including Dalopius gentilis Brown, Dalopius pennsylvanicus Brown, Ampedus areolatus (Say), Ampedus laesus (LeConte), Ampedus nigricollis (Herbst), two undescribed species of Ampedus, Aeolus mellillus (Say), Athous posticus (Melsheimer), Athous productus (Randall), Athous scapularis (Say), Hypoganus sulcicollis (Say), Sylvanelater mendax (LeConte), and Negastrius exiguus (Randall) are newly recorded in the Maritime Provinces as a whole, and one species, Dalopius pennsylvanicus, is newly recorded in Canada. Two species are removed from the faunal list of New Brunswick and two from the faunal list of Nova Scotia. Taxonomic changes proposed are: Anostirus vernalis (Hentz), new combination; Anostirus bipunctatus (Brown), new combination; Anostirus exclamationis (Fall), new combination; Beckerus new genus; Beckerus appressus (Randall), new combination; Beckerus barri (Lane), new combination; Corymbitodes dorothyae (Knull), new combina-tion; Corymbitodes elongaticollis (Hamilton), new combination; Corymbitodes moerens (LeConte), new combination; Corymbitodes pygmaeus (Van Dyke), new combination; Corymbitodes tarsalis (Melsheimer), new combination; Corymbitodes xanthomus (Horn), new combination; Metanomus blaisdelli (Van Dyke), new combination; Metanomus insidiosus (LeConte), new combination; Metanomus shastensis (Van Dyke), new combination; Nitidolimonius new genus; Nitidolimonius appalachius (Van Dyke), new combination; Nitidolimonius breweri (Horn), new combination; Nitidolimonius resplendens (Eschscholtz), new combination; Nitidolimonius weidtii (Angell), new combination; Paractenicera new genus; Paractenicera exilis (Notman), new combination; Paractenicera fulvipes (Bland), new combi- nation; Pseudanostirus hamatus (Say), new combination; Sylvanelater, new genus; Sylvanelater cylindriformis (Herbst), new combination, Sylvanelater furtivus (LeConte), new combination; Sylvanelater limoniiformis (Horn), new combination; Sylvanelater mendax (LeConte), new combination; and Elater viridis Say is regarded as a nomen dubium.

The Carabidae of Nova Scotia and New Brunswick are surveyed. The collecting history of the family in the region is reviewed. New records of 20 species are reported, 6 from New Brunswick and 15 from Nova Scotia. Six species are newly recorded in the Maritime Provinces (New Brunswick, Nova Scotia, and Prince Edward Island) as a whole. Six species are removed from the faunal list of Nova Scotia and one from the faunal list of New Brunswick. Consequently, 282 species of Carabidae are now known from Nova Scotia, 273 species from New Brunswick, and 329 from the Maritime Provinces as a whole. A new and earlier timeline (1942) is reported for the introduced Palearctic carabid, Bembidion properans (Stephens), in North America. The status of Stenolophus carbo Bousquet in the region is reviewed and its presence in Nova Scotia is considered doubtful. The historical origins of the Maritime fauna are discussed based on studies of post-glacial Coleoptera. These indicate at least three colonization phases, some elements of which are still apparent in the contemporary fauna. Elements of the native Nova Scotia fauna not found in New Brunswick (26 species), may represent colonization from New England across post-glacial land bridges and island chains. Elements of the native fauna found in New Brunswick and not Nova Scotia (31 species), may represent species that have reached the eastward limit of their distribution for climatic or environmental reasons; or that have found the Northumberland Strait and/or the isthmus of Chignecto an obstacle to geographical dispersal; or represent widely distributed boreal species (6 species) that should be sought in Nova Scotia. Eighteen species of Nova Scotia carabids have been recorded only from Cape Breton Island, two of which are known in Atlantic Canada solely from there. Although Cape Breton is separated from the mainland by the 1.5 km wide Strait of Canso, the number of flightless, native carabids present is proportionally greater than that in Nova Scotia overall, or the Maritime Provinces as a whole. Despite differences in land mass and distance to the neighbouring mainland, the faunas of Cape Breton, Prince Edward Island, and insular Newfoundland, exhibit similarities in size and composition, although Newfoundland's fauna has twice the proportion of Holarctic species. Cape Breton's carabid fauna is diminished compared to the neighbouring mainland, having only 57% of the native species. This may represent an island-associated diminution, the paucity of collecting, or a combination of both, although in comparison with other groups of Coleoptera the Carabidae appear relatively well represented. Within Atlantic Canada, New Brunswick has the lowest proportion (8.8%) of introduced carabids and the highest proportion (83.2%) of native, Nearctic species. Given the potential utility of carabids as bioindicators, and the wide range of disturbance to which the environment of the Maritime Provinces has been subjected, further research on this diverse group of beetles would be desirable.

The beetle families of the Bostrichiformia—the Derodontidae, Dermestidae, Bostrichidae, and Anobiidae – in the Maritime Provinces of Canada are surveyed. Seventy-four native and established introduced species are now known to occur including 30 found in New Brunswick, 65 in Nova Scotia, and 29 on Prince Edward Island. Seven species are newly recorded from New Brunswick, 24 from Prince Edward Island, and 37 from Nova Scotia for a total of 68 new provincial records. A total of 31 species are newly recorded in the Maritime Provinces as a whole, three of which, Dinoderus minutus (Fabricius), Ernobius filicornis LeConte, and Ernobius granulatus LeConte, are newly recorded in Canada. Two species, Ptilinus pruinosus Casey and Caenocara oculata (Say), are removed from the faunal list of New Brunswick, and one subspecies, Attagenus unicolor unicolor (Brahm), is removed from the faunal list of Prince Edward Island since no specimens or published records could be found to support their presence.        Additional records of six other exotic species intercepted at ports and points in the region, but not established here, are also reported. A specimen of the Palearctic Ptinus bicinctus Sturm collected in 1915 in Nova Scotia, establishes a new early timeline for this species in North America. The fauna of the region is distinguished by the very large proportion (37 of 74 species, i.e. 50%) of which is introduced. It is also distinguished by the large proportion (22 of 37 species, i.e. 60%) of the indigenous, native fauna that is apparently rare, perhaps as a result of the historical impact of forest management practices on these wood-boring, saproxylic species. The fauna is further evaluated from both zoogeographic and ecological perspectives.

New records of Coccinellidae in the Maritime Provinces of Canada are reported. The known fauna of the region consists of 47 species: 41 in Nova Scotia, 39 in New Brunswick, and 21 in Prince Edward Island. Of these, records are provided for 13 species newly recorded from Nova Scotia and 14 from Prince Edward Island. Two species, Diomus amabilis (LeConte) and Naemia seriata seriata Melsheimer, are newly recorded in Canada. Didion punctatum (Melsheimer) is removed from the fauna of PEI, and Coccidula lepida LeConte is removed from the fauna of NS, and Scymnus impexus Mulsant is removed from the faunas of NS and NB. Records of two adventive species not established in the region are also reported. Collecting effort in the three provinces and their sub-regions is briefly analyzed and compared. Biogeographic observations are provided in relation to the composition of the fauna as a whole, and of disjunct populations of six Nova Scotia coccinellids, several of which appear to be members of a coastal plain fauna that extends from New England to southern Nova Scotia. The potential vulnerability of the coccinellid fauna is discussed in the context of both adventive species in the region, and habitat loss and conservation.

The Erotylidae and Endomychidae of the Maritime Provinces are surveyed. Fifteen species are now known from the region, fourteen in Nova Scotia, seven in New Brunswick, and four on Prince Edward Island. Thirteen new provincial records (seven from Nova Scotia, three from New Brunswick, and three from Prince Edward Island) are reported. Four erotylids, Dacne quadrimaculata (Say), Triplax dissimulator (Crotch), Triplax flavicollis Lacordaire, Triplax macra LeConte; and two endomychids, Rhanidea unicolor (Ziegler) and Lycoperdina ferruginea LeConte, are newly recorded in the Maritime Provinces as a whole. New records of the rare endomychid, Hadromychus chandleri Bousquet & Leschen, are reported. The fauna is examined in a regional zoogeographic context, paying particular attention to the insular faunas of Cape Breton and Prince Edward Islands. Attention is also drawn to the number of species that have been very rarely collected. This apparent scarcity may be related to the long history of forest management in the region, in particular the effects of intensive forestry on the communities of forest fungi on which these species feed and depend. Attention is drawn to the importance of ongoing research to monitor their populations and assess how these species may be employed as indicators of the overall health forest ecosystems.

AbstractThe fauna of introduced rove beetles (Staphylinidae) in the Maritime Provinces of Canada is surveyed. Seventy-nine species have now been recorded. Of these, 73 have been found in Nova Scotia, 29 on Prince Edward Island, and 54 in New Brunswick. Twenty-five species are newly recorded in Nova Scotia, 16 on Prince Edward Island, and 10 in New Brunswick, for a total of 51 new provincial records. Of these, 15 species, Tachinus corticinus Gravenhorst, Mycetoporus lepidus (Gravenhorst), Habrocerus capillaricornis (Gravenhorst), Aleochara (Xenochara) lanuginosa Gravenhorst, Gnypeta caerulea (C.R. Sahlberg), Atheta (Microdota) amicula (Stephens), Cordalia obscura (Gravenhorst), Drusilla canaliculata (Fabricius), Deleaster dichrous (Gravenhorst), Coprophilus striatulus (Fabricius), Carpelimus subtilis (Erichson), Leptacinus intermedius Donisthorpe, Tasgius (Rayacheila) melanarius (Heer), Neobisnius villosulus (Stephens), and Philonthus discoideus (Gravenhorst), are newly recorded in the Maritime Provinces. Two of these, Atheta (Microdota) amicula and Carpelimus subtilis, are newly recorded in Canada. Leptacinus intermedius is removed from the faunal list of New Brunswick and Philhygra botanicarum Muona, a Holarctic species previously regarded as introduced in North America, is recorded for the first time in the Maritime Provinces. An examination of when species were first detected in the region reveals that, on average, it was substantially later than comparable dates for other, better known families of Coleoptera — an apparent indication of the comparative lack of attention this family has received. Some introduced species appear to be associated with the dry-ballast mechanism of introduction to the continent, while others are synanthropic and may have been inadvertently introduced in connection with agriculture, horticulture, or other processes associated with human activities. A substantial number are now established and well distributed, seemingly indicative of an early introduction into the region, the ability to successfully colonize a habitat and disperse within it, or a combination of these factors. Other species appear to be local in distribution, perhaps indicative of more recent introductions, more restricted ecological tolerances, a lesser ability to disperse, or a combination of these factors. These recent discoveries are discussed briefly in the context of the importance of taxonomic research and ongoing monitoring in order to detect and identify exotic species and monitor for new introductions and changes in existing native or introduced populations — all important in terms of assessing the risk of introductions to, and their impact on, native faunas and habitats.

The Ciidae of the Maritime Provinces of Canada are surveyed. Fifteen species are now known to occur in the region, thirteen in Nova Scotia, six in New Brunswick, and two on Prince Edward Island. Ten new provincial records  are reported. Seven species including Ceracis sallei Mellié, Ceracis thoracicornis (Ziegler), Cis creberrimus Mellié, Cis pistoria Casey, Cis subtilis Mellié, Malacocis brevicollis (Casey), and Orthocis punctatus (Mellié) are newly recorded in the Maritime Provinces as a whole. Cis americanus Mannerheim and Cis levettei (Casey) are newly recorded on Prince Edward Island, the first records of this family from the province.Collecting effort on Cape Breton Island, Prince Edward Island, and in New Brunswick has apparently been insufficient to fully document the ciid fauna of these areas. Some local and regional distribution patterns of ciids in the mainland of Nova Scotia and in the Maritime Provinces are suggested from the present data, but further collecting is required to confirm these. Zoogeographically, most of the region's ciids are members of either a boreal fauna (9 species) with Holarctic affinities, or a southeastern North American Nearctic fauna (5 species). The Maritime Provinces ciid fauna has representatives of five of the six known ciid host-use groups. Records of host fungi indicate that there are suitable hosts for all species of ciids found in the region in all three Maritime Provinces, indicating that ciids in the region appear not to be limited by availability of suitable host-fungi. However, Cis horridulus Casey, Cis striolatus Casey, and Cis subtilis Mellié, the three species in the Trametes host-use group, are very infrequently collected and apparently rare.Forests in Maritime Provinces have been greatly affected by forestry and disease, and such activities are known to impact fungal communities. Consequently such practices could have important repercussions for groups like the Ciidae that are reliant on fungi as both a food source and a habitat

Majka et al. (2007) surveyed the Carabidae of the Maritime Provinces of Canada (New Brunswick, Nova Scotia, and Prince Edward Island).  They reported 21 new provincial records, 6 from New Brunswick and 15 from Nova Scotia. They also checked prior records of the 329 species of Carabidae reported from the region and consequently removed Dyschirius larochellei Bousquet, Dyschirius setosus LeConte, Bembidion basicorne Notman, Myas cyanescens Dejean, and Amara lacustris LeConte from the faunal list of Nova Scotia. Voucher specimens could not be located nor were published records of these species for the province found. As a result they reported 282 species of Carabidae from Nova Scotia.

AbstractThe Tenebrionidae of the Maritime Provinces of Canada are surveyed. Forty-eight species have been reported from the region. Eleven of these species (ten Palearctic and one Nearctic) have been introduced to the region, five of which are apparently now extirpated. Dates of first detection of these species are provided for each province and North America. Thirteen species are newly recorded in New Brunswick, 25 in Nova Scotia, and 15 on Prince Edward Island, for a total of 53 new provincial records. Of these, 18 species including Bolitophagus corticola Say, Neatus tenebrioides (Palisot de Beauvois), Helops gracilis Bland, Blapstinus substriatus Champion, Hymenorus obesus Casey, Hymenorus picipennis Casey, Hymenorus pilosus (Melsheimer), Mycetochara bicolor (Couper), Mycetochara binotata (Say), Mycetochara fraterna (Say), Platydema excavatum (Say), Platydema teleops Triplehorn, Corticeus praetermissus (Fall), Alobates pennsylvanicus (DeGeer), Haplandrus fulvipes (Herbst), Xylopinus saperdioides (Olivier), an undescribed species of Paratenetus Spinola, and an undescribed species of Neatus LeConte are newly recorded for the Maritime Provinces as a whole. One of these, Helops gracilis, is recorded for the first time in Canada. The fauna is discussed from the perspective of the patterns of distribution of species in the region and their possible underlying causes. Island faunas are discussed, as is the saproxylic component of the fauna, with a brief consideration of the importance of this trophic group in the dynamics of forest ecosystems in the region.

AbstractSeventy-nine species of weevils are newly reported in Nova Scotia and 66 species are newly reported on Prince Edward Island, increasing the known provincial weevil faunas to 244 and 92 species, respectively. Thirty-six species are recorded for the first time in the Maritime Provinces; of these, Ceutorhynchus pallidactylus (Marsham), Listronotus dietzi O'Brien, Corthylus columbianus Hopkins, and Orchidophilus aterrimus (Waterhouse) are recorded for the first time in Canada. Orchidophilus aterrimus has been collected only in exotic domesticated orchids and is not established in the wild. Fourteen species previously recorded on Cape Breton Island, Nova Scotia, are reported from the provincial mainland. Four species — Curculio sulcatulus (Casey), Ceutorhynchus squamatus LeConte, Tachyerges niger (Horn), and Ips calligraphus (Germar) — are removed from the faunal list of Nova Scotia, and three species — Temnocerus cyanellus (LeConte), Curculio nasicus (Say), and Cryphalus ruficollis ruficollis Hopkins — are removed from the faunal list of Prince Edward Island. The combined known weevil fauna of the Maritime Provinces now totals 290 species. The adequacy of collection effort is discussed and in Nova Scotia, where collection effort has been greatest, distribution patterns of selected groups of species are examined. Island faunas are discussed with respect to those of Prince Edward Island and Cape Breton Island. Regional biogeographic patterns of species are also discussed, including possible disjunct populations in Nova Scotia and species that may not have crossed the isthmus of Chignecto to colonize Nova Scotia. Attention is drawn to the long history of introduced species in the region and to ongoing introductions through an examination of the earliest records for the 60 introduced species found in the region.

AbstractSeventy-seven species of weevils are newly reported in New Brunswick, increasing the known provincial fauna to 206 species. Trichapion nigrum (Herbst), Ceutorhynchus semirufus LeConte, and Listronotus laramiensis (Angell) are recorded for the first time in Canada. Three species, Bagous planatus LeConte, Plocamus hispidulus LeConte, and Dryocoetes granicollis (LeConte), are removed from the province's faunal list. Components of the fauna are discussed with a particular focus on the introduced species found in the province. Monitoring to detect changes of both native and introduced species is emphasized.
