New Coleoptera records from New Brunswick, Canada: Eucnemidae.

We report nine species of Eucnemidae new to the province and additional records for Onichodon canadensis (Brown) and Dromaeolus harringtoni Horn. Five species, Xylophilus cylindriformis (Horn), Entomophthalmus rufiolus (LeConte), Stethon pectorosus LeConte, Onichodon orchesides Newman, and Isarthrus rufipes (Melsheimer), are newly recorded for the Maritime provinces. This brings the total number of Eucnemidae recorded from New Brunswick to 15 species. Lindgren funnel traps are an effective tool for sampling the Eucnemidae.

Introduction

The Nearctic Eucnemidae (false click beetles) was revised by Muona (2000), and this treatment is indispensible for identifying members of this family from Canada. Eucnemidae larvae develop in wood infected by fungi that cause white rot, but details of the biology of most species are unknown (Muona 2000). The Eucnemidae appear to be good indicators of diverse forest structure, and the decline in populations of species in this family may be associated with forest management practices that promote a loss of deadwood and coarse woody debris (Muona 2000). Majka (2007), in a review of the Eucnemidae of the Maritime provinces (New Brunswick, Nova Scotia, Prince PageBreakEdward Island) of Canada, discussed the apparent rarity of members of this family in the context of the forest practices in the region and the role these practices may have on population numbers.

Majka (2007) reported six species of Eucnemidae from New Brunswick. (Brown) was reported as new. Intensive collecting of Coleoptera in New Brunswick by the first author and records obtained from by-catch samples during a study to develop a general attractant for the detection of invasive species of Cerambycidae have yielded additional provincial records. The goals of this contribution are to publish these new records and to report the apparent utility of Lindgren funnel traps (Lindgren 1983) for collecting Eucnemidae specimens. We also report additional provincial specimen records for two species hitherto represented in New Brunswick by only one specimen, and collection methods for all the Eucnemidae currently known from the province.

Methods and conventions

The following records are based on specimens collected as part of a general survey by the first author to document the Coleoptera fauna of New Brunswick. Additional provincial records were obtained from specimens contained in the collection at the Atlantic Forestry Centre, Natural Resources Canada, Canadian Forest Service, Fredericton, New Brunswick.

Collection methods

Various collection methods were employed to collect the Eucnemidae reported in this study. Details are outlined in Webster et al. (2009, Appendix). Many specimens were collected as by-catch in Lindgren 12-funnel traps (ConTech Inc., Delta, BC) baited with various attractants as part of a study to develop a general attractant for the detection of invasive species of Cerambycidae. These traps mimic tree trunks and are often effective for sampling species of Coleoptera that live in microhabitats associated with standing trees (Lindgren 1983). Details on the methods used for deployment of these traps are outlined in Webster et al. (in press). 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, are summarized 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 andPageBreak 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:

Results

We report nine species new to the province of New Brunswick and additional records for (Brown) and Horn. Five species, (Horn), (LeConte), LeConte, Newman, and (Melsheimer), are newly recorded for the Maritime provinces. This brings the total number of Eucnemidae recorded from New Brunswick to 15 species (Table 1).

Discussion

Majka (2007) noted that several species of Eucnemidae have been infrequently collected in the Maritime provinces. , , and , for example, were known from less than five specimens in the region. During our study, (28 specimens), (six specimens), and (28 specimens) were captured in sizeable numbers in Lindgren funnel traps in New Brunswick (Table 1). Muona (2000) noted that appears to have declined in recent years in the United States, as there were no records after 1972. Otto (2010) collected it recently (2005) in several sites in Wisconsin employing flight-intercept traps and noted that “its decline may be related to the conversions of forest lands for agriculture and industrial uses, particularly in the late 19th and early 20th centuries.” In New Brunswick, this species was collected in Lindgren funnel traps at four of the six sites sampled using these traps, suggesting that this species is not uncommon here. Nine other eucnemid species were also captured in numbers of five or more individuals over the past 4 years in these traps. Indeed, six of the nine eucnemid species newly recorded for New Brunswick in this study were collected solely in Lindgren traps, and nearly 90% of all individuals of this family and all 15 species known from the province were captured in Lindgren funnel traps between 2008 and 2011, indicating that Lindgren funnel traps are effective for sampling members of this family.
