We report ten new species records for the Coleoptera fauna of New Brunswick, Canada from the families Dermestidae, Endecatomidae, Bostrichidae, and Ptinidae. Anthrenus fuscus Olivier and Anthrenus museorum (Linnaeus) of the family Dermestidae are newly recorded for New Brunswick. Endecatomus rugosus (Randall) and the family Endecatomidae are recorded for the first time for New Brunswick and the Maritime provinces. Two Bostrichidae, the adventive Dinoderus minutus (Fabricius) and the native Stephanopachys substriatus (Paykull), are newly recorded for the province. Five species of Ptinidae, the adventive Anobium punctatum (DeGeer) and Microbregma emarginatum emarginatum (Duftschmid), and the native Hadrobregmus notatus (Say), Ptilinus lobatus Casey, and Ptilinus ruficornis Say are added to the faunal list of New Brunswick. Collection data, habitat data, and distribution maps are presented for all these species.
Dermestidae, Endecatomidae, Bostrichidae, Ptinidae, Canada, New Brunswick, new records
This paper treats new species records from New Brunswick, Canada of the Coleoptera families Dermestidae, Endecatomidae, Bostrichidae, and Ptinidae. The fauna of these families from New Brunswick and the Maritime provinces (New Brunswick, Nova Scotia, Prince Edward Island) was recently treated by
The following records are based, in part, on specimens collected as part of a general survey by the first author to document the Coleoptera fauna of New Brunswick and from a study to develop improved lures for survey of potentially invasive species of Cerambycidae. Additional 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 specimens reported in this study. Details are outlined in
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:

The classification of the Dermestidae, Endecatomidae, Bostrichidae, and Ptinidae follows
The Dermestidae (skin beetles) are generally scavengers, feeding on dried animal materials such as dried carcasses, old feathers, and plant materials with high protein content (
