Twenty-two species of Elateridae are newly reported for New Brunswick, Canada. Negastrius exiguus (Randall) 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 obtectum (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.
Elateridae, new records, Canada, New Brunswick
The Elateridae (click beetles) is a species-rich family of beetles with about 965 named species in North America (
The Elateridae of the Maritime provinces (New Brunswick, Nova Scotia, Prince Edward Island) was reviewed by
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, Canadian Forest Service - Atlantic Forestry Centre, Fredericton, New Brunswick.
Collection methodsVarious methods were employed to collect the species reported in this study. Details are outlined in
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 celluloid microslides and pinned with the specimens they originated from.
DistributionDistribution 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:

ResultsTwenty-two species of Elateridae are newly reported for New Brunswick, Negastrius exiguus (Randall) is removed from the faunal list, and Agriotes pubescens Melsheimer reinstated 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.
