New Coleoptera records from New Brunswick, Canada: Cerambycidae

Abstract Five species of Cerambycidae, Acmaeops discoideus (Haldeman), Anelaphus villosus (Fabricius), Phymatodes species (CNC sp. n. #1), Sarosesthes fulminans (Fabricius), and Urgleptus signatus (LeConte) are newly recorded for New Brunswick, Canada. All but Acmaeops villosus are new to the Maritime provinces. Phymatodes testaceus (Linnaeus) is removed from the faunal list of the province as a result of mislabeled specimens, records of Phymatodes maculicollis LeConte are presented confirming the presence of this species in New Brunswick, and the first recent records ofNeospondylis upiformis (Mannerheim) are presented. Additional records are given for the recently recorded Phymatodes aereus (Newman), indicating a wider distribution in the province. Collection data, habitat data, and distribution maps are presented for each species.


Introduction
The Cerambycidae (longhorn beetles) fauna of New Brunswick and the Maritime provinces (New Brunswick, Nova Scotia, Prince Edward Island) were reviewed by McCorquodale and Bondrup-Nielsen (2004) and Webster et al. (2009). Majka et al. (2007) reviewed the fauna of Prince Edward Island. Later, McCorquodale (2010) reviewed the longhorn beetle fauna of the Atlantic Maritime Ecozone in the context of collections and sources of information, the geographic distribution within the ecozone and overall global distribution, host plant usage, and anthropogenic effects on the fauna. Webster et al. (2009) reported 48 species as new to the province, bringing the total number of species known from New Brunswick to 116. More recently,  added Phymatodes aereus (Newman) and Typocerus sparsus Le-Conte to the faunal list. Here, we add six species of Cerambycidae to the faunal list of New Brunswick.

Collection methods
Most specimens were collected from Lindgren funnel trap samples during 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). [See Webster et al. (in press) for details of the methods used to deploy Lindgren 12-funnel traps and for sample collection.] Traps were baited with commercially purchased highrelease-rate lures of ethanol, α-pinene (mixture of 93% (-) and 7% (+) α-pinene), or "BSLB kairomone" (Contech International, Inc.; a blend of monoterpenes attractive to Tetropium fuscum (Fabr.) and T. cinnamopterum Kirby) (Sweeney et al. 2006) or with racemic 3-hydroxyhexan-2-one or racemic 3-hydroxyoctan-2-one, synthesized at the Fredericton laboratory (See Hanks et al. (2007) and reference therein for details on their synthesis) and loaded into release devices by Contech International, Inc. (Delta BC). Specific enantiomers of the latter compounds have been identified as long-distance sex/aggregation pheromones in several species of Cerambycinae (Fettköther et al. 1995;Leal et al. 1995;Lacey et al. 2004Lacey et al. , 2007. The pheromones are naturally emitted by males and attract females or both sexes depending on the species (Lacey et al. 2004Hanks et al. 2007). 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

Species accounts
All records below are species newly recorded for New Brunswick, Canada, unless noted otherwise (additional records). Species followed by ** are newly recorded from the Maritime provinces of Canada. Collection and habitat data. Adults were captured in Lindgren funnel traps deployed in an old-growth white spruce (Picea glauca (Moench) Voss) and balsam fir (Abies balsamea (L.) Mill.) forest. Specimens were captured during June and July in New Brunswick. Larvae of this species probably feed in the roots of fir (Abies) or pine (Pinus) (Yanega 1996 Collection and habitat data. One individual was collected in late June from flowers of elderberry (Sambucus canadensis L.) on a roadside near an area with red pine (Pinus resinosa Ait.) and white pine (Pinus strobus L.). The larvae of this species develop in Pinus spp. (Yanega 1996). Collection and habitat data. Phymatodes aereus was captured in Lindgren funnel traps baited with racemic 3-hydroxyhexan-2-one deployed in an old red oak (Quercus rubra L.) forest, an old silver maple (Acer saccharinum L.) forest, and in an old red pine forest with scattered hardwoods. Larvae of this uncommon species develop in dead Quercus (Lingafelter 2007). Adults in New Brunswick were captured during May, June, and July. Collection and habitat data. Phymatodes maculicollis larvae develop under bark of spruce (Picea) and fir branches (Yanega 1996). This species, which is considered rare in the East, was captured in Lindgren funnel traps baited with racemic 3-hydroxyhexan-2-one deployed in an old-growth eastern white cedar (Thuja occidentalis L.) forest, an old-growth white spruce and balsam fir forest, an old red pine forest, an old mixed forest, and in an old red oak forest with scattered conifers. Adults were captured during May, June, and July.

Distribution in Canada and
Distribution in Canada and Alaska. YK, BC, QC, NB (McNamara 1991). Mc-Namara (1991) listed Phymatodes maculicollis for New Brunswick but no supporting voucher specimens or other published records could be located by Webster et al. (2009). The above records establish the presence of this species for the province. Collection and habitat data. One individual was captured during July in a Lindgren funnel trap in an old-growth forest with hemlock (Tsuga canadensis (L.) Carr.), American beech (Fagus grandifolia Ehrh.), and sugar maple (Acer saccharum Marsh.).
Distribution in Canada and Alaska. QC, NB (Yanega 1996). According to Yanega (1996) this undescribed species is related to Phymatodes ater LeConte but lacks the prominent pronotal calli and possesses finer elytral punctures.

Phymatodes testaceus (Linnaeus, 1758)
http://species-id.net/wiki/Phymatodes_testaceus Webster et al. (2009) reported Phymatodes testaceus from New Brunswick based on a series of specimens collected from Pleasantfield in Queens Co. There are no towns with this name in Queens Co., New Brunswick. The original Forest Insect and Disease Survey slip (at AFC) was examined and Pleasantfield is actually in Queens Co., Nova Scotia, indicating that these specimens had been mislabeled. Phymatodes testaceus is accordingly removed from the faunal list of New Brunswick.
Distribution in Canada and Alaska. ON, QC, NB (McNamara 1991). This species was abundant at the Cranberry Lake P.N.A. (Protected Natural Area) and will probably be found at other localities in New Brunswick and the other Maritime provinces where red oak occurs using traps baited with racemic 3-hydroxyhexan-2-one.
Collection and habitat data. Adults were captured during July and August in Lindgren funnel traps baited with ethanol deployed in the forest canopy of an old red oak forest. Larvae are twig pruners of most eastern hardwoods and shrubs (Lingafelter 2007
