New Coleoptera records from New Brunswick, Canada: Dermestidae, Endecatomidae, Bostrichidae, and Ptinidae.

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.

Introduction

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 Majka (2007). Intensive sampling in New Brunswick by the first author and others has yielded additional new PageBreakprovincial records in the above families. The purpose of this paper is to report on these new records. A brief synopsis of each family is included in the results below.

Methods and conventions

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 methods

Various methods were employed to collect the specimens reported in this study. Details are outlined in Webster et al. (2009, Appendix). Many specimens were also collected from Lindgren 12-funnel trap samples during a study to develop a general attractant for the detection of invasive species of Cerambycidae. These traps visually mimic tree trunks and are often effective for sampling species 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 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 section for each species.

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:PageBreak

Species accounts

All records below are species newly recorded for New Brunswick, Canada. Species followed by ** are newly recorded from the Maritime provinces of Canada.

The classification of the Dermestidae, Endecatomidae, Bostrichidae, and Ptinidae follows Bouchard et al. (2011).

Family Dermestidae Latreille, 1804

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 (Kingsolver 2002). Some species occur in bee and wasp nests and feed on pollen stores or dried insect remains. A number of species, such as the khapra beetle ( Everts), are stored-product pests and are serious pests in granaries (Hinton 1945; Kingsolver 1963; Bousquet 1990). Adults of many dermestid species occur on flowers and feed on pollen and nectar (Kingsolver 2002). Majka (2007) reviewed the Dermestidae of the Maritime provinces and reported seven species for New Brunswick. (Linnaeus), Reitter, and LeConte were reported as new. Here, we report two additional species for the province. See Majka (2007) for a list of the other species known from New Brunswick and the other Maritime provinces.

Collection and habitat data.

This adventive Palaearctic species is a minor pest in flour mills, warehouses, and homes (Bousquet 1990) and has been reported from bird and wasp nests, and under bark in natural conditions (Woodroffe and Southgate 1954). Specimens from New Brunswick were collected during May and July, otherwise no other collection data was provided.

adults were collected from flowers of mountain ash ( sp.) and an ornamental , and by sweeping foliage in a mature hardwood forest. One adult was found in an insect collection. Adults were captured during May and June. The larvae of this household pest feed on wool, fur, skins, museum specimens, and other animal products. Adults feed on nectar and pollen (Bousquet 1990).

Family Endecatomidae LeConte, 1861

The Endecatomidae is a small monogeneric family with four Holarctic species. Lawrence and Newton (1995) treated it as a separate family, but Ivie (2002) treated it as a subfamily of the Bostrichidae, and this reference should be consulted for arguments for and againstPageBreak retaining this subfamily in the Bostrichidae. Here, we follow the classification in Bouchard et al. (2011). Members of this genus feed on fungi (Crowson 1961). (Randall) is the only species of this family recorded from Canada. Here, we record this species and family for the first time from New Brunswick and the Maritime provinces.

Family Bostrichidae Latreille, 1802

Larvae of most species of Bostrichidae (the bostrichid beetles) are wood borers and receive their nutrition from the starch content of wood they consume (Gerberg 1957; Ivie 2002). A few species are stored product pests. Those that live in wood typically infest dead and dry wood of angiosperms and dried roots of herbaceous plants and a number of species are subject to distribution around the world by commerce (Ivie 2002). McNamara (1991a, b) reported 23 species of Bostrichidae from Canada. Only one species of Bostrichidae ( (Olivier)) was recorded from New Brunswick by McNamara (1991a). Majka (2007) added the adventive and cosmopolitan (Stephens) and (Goeze) to the faunal list of the province. (Lesne) was reported from Riverview, Albert Co., New Brunswick, but was considered an intercepted, adventive species that is not established in the region (Majka 2007). Here, we add two additional species to the faunal list of the province. See Majka (2007) for a list of the other species known from New Brunswick and the other Maritime provinces.

This adventive species is often found in warehouses and places where bamboo products are stored (Bousquet 1990). Adult specimens from New Brunswick emerged from a carved wood statue and basket. This species develops in bamboo in the tropics but can be found in dried food products in North America (Spillman 1982). It is not clear if this species is established in New Brunswick.

Family Ptinidae Latreille, 1802

The Ptinidae (death watch and spider beetles) (formerly Anobiidae) are borers in bark, dry wood, twigs, galls, pine cones, and fungi (many Anobiinae) or feed on accumulated dried animal and plant material, and are found in bird, mammal, and solitary bee nests (mostly Ptininae) (Hinton 1941; Philips 2002). A number of species are important pests and have been widely distributed by commerce around the world. The furniture beetle, (DeGeer), causes damage to furniture, woodwork of houses, and books (Philips 2002). The drugstore beetle, (Linnaeus), and the cigarette beetle, (Fabricius), are important stored-products pests (tobacco, spices, cayenne pepper) (Philips 2002). McNamara (1991a) and Bousquet (1991b) reported 95 species of Ptinidae from Canada and 17 species from New Brunswick. In a recent review of the Ptinidae (as Anobiidae) of the Maritime provinces, Majka (2007) newly recorded the adventive (Linnaeus), (Fabricius), and (Panzer) from New Brunswick, bringing the total number of species known from the province to 20. Here, wePageBreak newly report another five species from the province. See Majka (2007) for a list of the other species known from New Brunswick and the other Maritime provinces.
