New Coleoptera records from New Brunswick, Canada: Lycidae

Abstract Eight species of Lycidae are newly recorded from New Brunswick, Canada, bringing the total number of species known from the province to 16. The first documented records from New Brunswick are provided for Greenarius thoracicus (Randall) Erotides scuptilis (Say), and Calopteron terminale (Say) reported by Majka et al. (2011). Eropterus arculus Green, Lopheros crenatus (Germar), and Calochromus perfacetus (Say) are reported for the first time in the Maritime provinces. Collection data, habitat data, and distribution maps are presented for all these species.


Introduction
The Lycidae of North America was reviewed by Green 1949Green , 1950Green , 1951Green , 1952Green , 1953Green , 1954, and all species in the Maritime provinces of Canada can readily be determined using these keys. Larvae of the Lycidae are usually found in rotten logs, in leaf litter, and under bark and probably feed on myxomycetes or metabolic products of fungi (Lawrence 1982;Miller 2002). Adults are usually found on leaves or flowers and feed on nectar and honeydew. Larvae and adults are distasteful, and adults are often brightly colored and probably aposomatic in coloration (Miller 2002).
Twenty-nine species are known from Canada and five were reported from New Brunswick by McNamara (1991). Majka et al. (2011) reported Greenarius thoracicus (Randall) Erotides scuptilis (Say), and Calopteron terminale (Say) as occurring in New Brunswick but did not provide any supporting references or data. Here, eight species of Lycidae are newly reported from New Brunswick, Canada, as well as the first documented records for Greenarius thoracicus (Randall) Erotides scuptilis (Say), and Calopteron terminale (Say).

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.

Collection methods
Various collection methods were employed to collect the Lycidae reported in this study. Details are outlined Webster et al. (2009, Appendix). A number of specimens were also 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, is summarized in collection and habitat data for each species.

Specimen preparation
Males of some species of Lycidae (all Plateros sp.) were dissected to confirm their identity. The genital structures were dehydrated in absolute alcohol and mounted on points and then pinned with the specimens from which they originated.

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: Acronyms of collections examined or where specimens reside referred to in this study are as follows:

Species accounts
All records below are species newly recorded from New Brunswick, Canada unless noted otherwise (additional records). Species followed by ** are newly recorded from the Maritime provinces. The classification of the Lycidae follows Kazantsev (2004) and Bouchard et al. (2011). Collection and habitat data. Adults were captured in Lindgren funnel traps deployed in an old-growth eastern white cedar (Thuja occidentalis L.) forest, old red oak (Quercus rubra L.) forest, red spruce (Picea rubens Sarg.) forest, old red pine (Pinus resinosa Ait.) forest, and an old mixed forest. Adults were captured during June and July.
Distribution in Canada and Alaska. BC, AB, MB, ON, QC, NB (Green 1951;McNamara 1991;Majka et al. 2011). Greenarius thoracicus was listed as occurring in New Brunswick by Majka et al. (2011)  Collection and habitat data. Eropterus arculus adults were collected by beating or sweeping foliage and hand picking adults from foliage in mature hardwood forests with American beech (Fagus grandifolia Ehrh.) and sugar maple (Acer saccharum Marsh.), regenerating mixed forests, and along a river margin. One individual was captured in a Lindgren funnel trap deployed in an old red oak forest. Adults were collected during July and August. Collection and habitat data. This species was captured in Lindgren funnel traps deployed in a mature hardwood forest (beech and sugar maple), an old red oak forest, and an old red pine forest. One adult was found under bark of a rotten sugar maple log in a mature hardwood forest (mostly sugar maple). Adults were captured during July and August. (Green 1951;McNamara 1991;Dollin et al. 2008;Bishop et al. 2009 Collection and habitat data. This species was collected by beating or sweeping foliage and hand picking adults from foliage in mixed and regenerating mixed forests during July and August. (Green 1951;McNamara 1991;Majka et al. 2011). Erotides sculptilis was listed as occurring in New Brunswick by Majka et al. (2011)  Collection and habitat data. Calopteron terminale (Say) was collected from drift material along a lakeshore, from (hand picking adults on) foliage in a silver maple (Acer saccharinum L.) forest, an old red oak forest, and regenerating mixed and mixed forests, and from under bark of a conifer stump in a clearcut. On individual was collected from flowers of S. alba, another was captured in a Lindgren funnel trap. Adults were captured during August and September.

(2011)  Collection and habitat data. This species was captured in mixed and regenerating mixed forests, in an old red oak forest, and in an old red pine forest. Adults were collected at a black-light trap, by sweeping foliage, and in Lindgren funnel traps. Adults were collected during July and August.

One individual was captured in a Lindgren funnel trap deployed in a red spruce forest and another was collected by sweeping foliage in a red maple (Acer rubrum L.) and alder (Alnus sp.) swamp. Both adults were captured during July.
