Abstract

Thirteen species of Tenebrionidae are newly reported for New Brunswick, Canada. Paratenetus punctatus Spinola, Pseudocistela brevis (Say), Mycetochara foveata (LeConte), and Xylopinus aenescens LeConte are recorded for the first time from the Maritime provinces. Platydema excavatum (Say) is removed from the faunal list of New Brunswick, and the presence of Platydema americanum Laporte and Brullé for the province is confirmed. This brings the total number of species of Tenebrionidae known from New Brunswick to 42. Two species of Zopheridae, Bitoma crenata Fabricius and Synchita fuliginosa Melsheimer, are newly recorded for New Brunswick, bringing the number of species known from the province to four. Bitoma crenata is new to the Maritime provinces. Collection and habitat data are presented for these species.

Introduction

The Tenebrionidae is the sixth largest families of beetles, with 1184 species known from North America (Marske and Ivie 2003). Most species occur in arid regions of the southwestern United States, and only 141 species were recorded from Canada by Bousquet and Campbell (1991) and Campbell (1991a). Forty-eight species were reported from the Maritime provinces (Majka et al. 2008). There have been few recent revisions of genera that occur in Canada (Hymenochara - Campbell (1978b); Mycetochara - Campbell (1978a)), and some members of this family can be difficult to determine to species.

Most Tenebrionidae occurring in eastern Canada are associated with forests and live in or are associated with dead wood; a few are subcortical. A number of species are associated with fruiting bodies of polypore fungi, and a few species are found on flowers and leaves. Most of our adventive species are stored product pests. For more details, see Aalbu et al. (2002).

Majka et al. (2008) reported 33 species of Tenebrionidae from New Brunswick, 13 as new to the province, in their review of the Tenebrionidae of the Maritime provinces (New Brunswick, Nova Scotia, Prince Edward Island). Here, we report 13 additional species for the province.

The Zopheridae, which includes the Colydiidae (Ślipiński and Lawrence 1999), contains only a few species in eastern Canada. Adults live under bark or in rotten wood, and some species feed on fruiting bodies of polypore fungi (Phellopsini) (Ślipiński and Lawrence 1999; Ivie 2002). See Ivie (2002) for a general review of the North American members of this family. Three species (Phellopsis obcordata (Kirby), Lasconotus borealis Horn, Synchita fuliginosa Melsheimer) were reported for the Maritime provinces (Bousquet 1991; Campbell 1991b; Majka et al. 2006). Only Lasconotus borealis and Phellopsis obcordata were reported from New Brunswick (Bousquet 1991; Majka et al. 2006; Foley and Ivie 2008). Here, we report two additional species for the province.

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.

Collection methods

Various collection methods were employed to collect the species reported in this study. Details are outlined in Campbell (1973) and Webster et al. (2009, Appendix). See Webster et al. (in press) for details of the methods used for deployment of Lindgren 12-funnel traps and 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.

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*

*Newfoundland and Labrador are each treated separately under the current Distribution in Canada and Alaska.

Results

Thirteen species of Tenebrionidae are newly reported for New Brunswick. Paratenetus punctatus Spinola, Pseudocistela brevis (Say), Mycetochara foveata (LeConte), and Xylopinus aenescens LeConte are recorded from the Maritime provinces for the first time; Platydema excavatum (Say) is removed from the faunal list of New Brunswick, and the presence of Platydema americanum in New Brunswick is confirmed. This brings the total number of species known from New Brunswick to 42 (Table 1).

Collection localities in New Brunswick, Canada of Paratenetus punctatus.

Collection and habitat data.

This species was collected from various forest types in New Brunswick, including hardwood forests with sugar maple (Acer saccharum Marsh.) and American beech (Fagus grandifolia Ehrh.), a red oak (Quercus rubra L.) forest, eastern white cedar (Thuja occidentalis L.) forests, an old red pine (Pinus resinosa Ait.) forest, and mixed forests. Most adults were collected from Lindgren funnel traps (29). Adults with specific microhabitat data were collected from moss and leaf litter at base of trees, beating or sweeping foliage, and beating birch branches that had dead dried leaves. Adults were collected during April, May, June, and July.

Most adults from New Brunswick were collected from dried polypore fungi, partially dried Pleurotus sp., or other polypore fungi on logs or standing dead trees in mixed and hardwood (silver maple, sugar maple, and beech) forests. One individual was collected from under bark of a conifer stump in late November. This was probably an overwintering site. Adults were collected during May, June, July, August, September, and November.

Remarks.

The specimen of Platydema excavatum reported in Majka et al. (2008) was misidentified by C.G. Majka and was a specimen of Platydema teleops Triplehorn (collected by R. P. Webster on 5 June 2003, Charters Settlement, N.B., not 3 June 2003 as reported in Majka et al. 2008) (see below). In view of this, Platydema excavatum is removed from the faunal list of New Brunswick.

Collection and habitat data.

Adults of this species were collected in red oak, and red oak and red maple forests, and a silver maple swamp. Many individuals were collected at night from the trunks of dead or dying red oak trees, usually on areas of the trunk without bark. One individual was collected from under loose bark of an oak during the day. Other individuals were captured in Lindgren funnel traps deployed in the canopy of silver maples. Adults were collected during July and August.

Most (16) adults from New Brunswick were captured in Lindgren funnel traps deployed in a mature hardwood forest, an old red oak forest, an old silver maple swamp, and an old red pine forest. Individuals with more specific bionomic data were reared from American elm (Ulmus americana L.) bolts and taken at an ultraviolet light. Elsewhere, Synchita fuliginosa have been found under bark of a variety of hardwood species or collected at light (Stephan 1989).
