ZooKeys 179: 93–113. doi: 10.3897/zookeys.179.2603 Abstract Twenty-two species of Elateridae are newly reported for New Brunswick, Canada. Negastrius exiguus (Ran- dall) is removed from the faunal list and Agriotes pubescens Melsheimer is re-instated as a member of the New Brunswick fauna. Agriotes pubescens Melsheimer, Dalopius brevicornis W. J. Brown, Danosoma obtec- tum (Say) and Megapenthes solitarius Fall are newly reported for the Maritime provinces. Collection data, bionomic data, and distribution maps are presented for all these species. Keywords Elateridae, new records, Canada, New Brunswick Introduction The Elateridae (click beetles) is a species-rich family of beetles with about 965 named species in North America (Johnson 2002) and 369 species and subspecies from Canada and Alaska (Bousquet 1991). Although some groups are fairly well known taxonomi- cally, genera such as Ampedus and Dalopius are in need of revisionary study and include a number of undescribed species (Johnson 2002). Larvae of some species of Elateri- dae are rhizophagus and are important agricultural pests; larvae of other species are predaceous, often living in soil, subcortical habitats, or rotten logs (Johnson 2002). However, little is known about the biology of most species. Copyright Her Majesty the Queen in Right of Canada.

Webster et al. / ZooKeys 179: 93–113 (2012) The Elateridae of the Maritime provinces (New Brunswick, Nova Scotia, Prince Edward Island) was reviewed by Majka and Johnson (2008). They provided a detailed historical overview the collection of the Elateridae and other families of beetles in the Maritime provinces and a taxonomic review of the genus Ctenicera, which was in need of taxonomic review and generic re-assignment. Ninety-eight species were reported for New Brunswick, 13 as new provincial records; Agriotes pubescens Melsheimer, Athous campyloides Newman, and Cardiophorus cardisce (Say) were removed from the fau- nal list of the province by Majka and Johnson (2008). Later, Douglas (2011) newly reported Pseudanstirus nigricollis (Bland) and the adventive Hemicrepidius niger (Lin- naeus) from New Brunswick. Hemicrepidius niger was also reported from Ontario and these represented the first records of this Eurasian species from North America. Here, we newly report 22 elaterid species from New Brunswick. Methods and conventions The following records are based on specimens collected during a general survey by the first author to document the Coleoptera fauna of New Brunswick and from by-catch samples obtained during a study to develop a general attractant for the detection of invasive species of Cerambycidae. Additional provincial records were obtained from specimens contained in the collection belonging to Natural Resources Canada, Cana- dian Forest Service - Atlantic Forestry Centre, Fredericton, New Brunswick. Collection methods Various methods were employed to collect the species reported in this study. Details are outlined in Webster et al. (2009, Appendix). Many specimens were also collected from 12-unit Lindgren funnel traps set in various forest habitats in New Brunswick between 2008 and 2011. These traps mimic tree trunks and are often effective for sampling spe- cies of Coleoptera that live in microhabitats associated with standing trees (Lindgren 1983). See Webster et al. (in press) for details of the methods used to deploy Lindgren funnel traps and for sample collection. A description of the habitat was recorded for all specimens collected during this survey. Locality and habitat data are presented exactly as on labels for each record. This information, as well as additional collecting notes, is summarized and discussed in the collection and habitat data section for each species. Specimen Preparation Males of some species of Elateridae were dissected to confirm their identity. The genital structures were dehydrated in absolute alcohol and mounted in Canada balsam on cel- luloid microslides and pinned with the specimens they originated from. New Coleoptera records from New Brunswick, Canada: Elateridae 95 Distribution Distribution maps, created using ArcMap and ArcGIS, are presented for each species in New Brunswick. Every species is cited with current distribution in Canada and Alaska, using abbreviations for the state, provinces, and territories. New records for New Brunswick are indicated in bold under Distribution in Canada and Alaska. The following abbreviations are used in the text: AK Alaska MB Manitoba YT Yukon Territory ON Ontario NT Northwest Territories QC Quebec NU Nunavut NB New Brunswick BC British Columbia PE Prince Edward Island AB Alberta NS Nova Scotia SK Saskatchewan NF & LB Newfoundland and Labrador Acronyms of collections examined or where specimens reside referred to in this study are as follows: AFC Atlantic Forestry Centre, Natural Resources Canada, Canadian Forest Service, Fredericton, New Brunswick, Canada CNC Canadian National Collection of Insects, Arachnids and Nematodes, Agri- culture and Agri-Food Canada, Ottawa, Ontario, Canada NBM New Brunswick Museum, Saint John, New Brunswick, Canada RWC Reginald Webster Collection, Charters Settlement, New Brunswick, Canada Results Twenty-two species of Elateridae are newly reported for New Brunswick, Negastrius ex- iguus (Randall) is removed from the faunal list, and Agriotes pubescens Melsheimer rein- stated as a member of the New Brunswick fauna, bringing the total number of species known from the province to 122. Agriotes pubescens Melsheimer, Dalopius brevicornis, Danosoma obtectum (Say), and Megapenthes solitarius Fall are newly reported for the Maritime provinces. Several apparently undescribed Ampedus sp. have also been found in New Brunswick but these are not reported here. Species accounts All records below are species newly recorded for New Brunswick, Canada unless noted otherwise (additional records). Species followed by ** are newly recorded from the Maritime provinces of Canada. The classification of the Elateridae follows Bouchard et al. (2011). 96 Reginald P.
