Abstract

We report 21 new species records for the Coleoptera fauna of New Brunswick, Canada, seven of which are new records for the Maritime provinces. Four species of Mycetophagidae (Litargus didesmus Say, Litargus tetrapilotus LeConte, Mycetophagus punctatus Say, and Mycetophagus quadriguttatus Müller) are newly reported for the province of New Brunswick. Litargus didesmus is newly recorded for the Maritime provinces. Seven species of Tetratomidae are added to the faunal list of New Brunswick: Eustrophus tomentosus Say, Penthe obliquata (Fabricius), and Tetratoma tessellata Melsheimer are new to New Brunswick: Hallomenus serricornis LeConte, Pisenus humeralis Kirby, Synstrophus repandus (Horn), and Tetratoma variegata Casey, which are newly recorded for New Brunswick and the Maritime provinces. Ten additional species of Melandryidae are reported from New Brunswick, of which Orchesia cultriformis Laliberté, Orchesia ovata Laliberté, Phloeotrya fusca (LeConte), Scotochroides antennatus Mank, Spilotus quadripustulatus (Melsheimer), Symphora flavicollis (Haldeman), Symphora rugosa (Haldeman), and Zilora hispida LeConte are new for the province, and Microscapha clavicornis LeConte and Zilora nuda Provancher are newly recorded for the Maritime provinces. In addition, we report numerous additional records for three species of Mycetophagidae and one species of Melandryidae previously recorded from New Brunswick that suggest these species are more widely distributed than previously known. Collection, habitat data, and distribution maps are presented for all these species.

Introduction

The Melandryidae and Tetratomidae of the Maritime provinces of Canada were reviewed by Majka and Pollock (2006). More recently, Majka (2010) reviewed the Mycetophagidae of the region. Intensive collecting in New Brunswick by the first author since 2003 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 new provincial 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 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 in Lindgren 12-funnel traps placed at various sites in New Brunswick from 2008–2011 as part of 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 species reported in this study. Details are outlined in Webster et al. (2009, Appendix). Many specimens were collected in Lindgren funnel traps. 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 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 collection and habitat data 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

Results 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 (New Brunswick, Nova Scotia, Prince Edward Island) of Canada.

The classification of the Mycetophagidae, Tetratomidae, and Melandryidae follows Bouchard et al. (2011).

Family Mycetophagidae Leach, 1815

The Mycetophagidae (the hairy fungus beetles) are found in mushrooms or fleshy polypore fungi that have begun to dehydrate, under fungus-covered bark or on moldy vegetative material (Young 2002). Some species, such as Typhaea stercorea (Linnaeus), are often found in stored products. Majka (2010) reviewed the Mycetophagidae of the Maritime provinces and reported four species for New Brunswick, three for the first time. Four additional species (Mycetophagus punctatus Say, Mycetophagus quadriguttatus Müller, Litargus didesmus Say, and Litargus tetrapilotus LeConte) are reported here from the province, as well as new localities and additional bionomic data for the three species recently reported by Majka (2010) (Table 1). Litargus didesmus is newly recorded for the Maritime provinces.

Collection localities in New Brunswick, Canada of Mycetophagus flexuosus.

Collection and habitat data.

Adults of Mycetophagus flexuosus in New Brunswick were found in hardwood forests with sugar maple (Acer saccharum Marsh.) and American beech (Fagus grandifolia Ehrh.), an old red oak (Quercus rubra L.) forest, mixed forests, and an old (180-year-old) red pine (Pinus resinosa Ait.) forest. This species was found in partially dried Pleurotus species on dead, standing sugar maples, on a dead, standing trembling aspen (Populus tremuloides Michx.), in a decayed log covered with gilled mushrooms and polypore fungi, in a pile of moldy corncobs and cornhusks, and at an ultraviolet light. Specimens were also captured in Lindgren funnel traps at several localities. Cline and Leschen (2005) reported Mycetophagus flexuosus from the oyster mushroom, Pleurotus ostreatus Fries. Other fungal associations with this species were reported in Majka (2010). Adults in New Brunswick were collected during April, May, June, July, August, and September.

Distribution in Canada and Alaska.

MB, ON, QC, NB (Bousquet 1991; Majka 2010). Makja (2010) reported this species for the first time from New Brunswick and the Maritime provinces based on two specimens collected in Edmundston (Madawaska Co.) by Richard Migneault. The above records indicate that this species in not uncommon and is probably widespread in New Brunswick.

Collection localities in New Brunswick, Canada of Mycetophagus punctatus.

Collection and habitat data.

All the records of this species from New Brunswick were from hardwood forests (sugar maple and American beech, red oak and red maple (Acer rubrum L.)). Most adults were collected from partially dried Pleurotus species, including the oyster mushroom, Pleurotus ostreatus, on dead, standing sugar maples and a dead, standing poplar (probably trembling aspen). One individual was captured in a Lindgren funnel trap. Cline and Leschen (2005) also reported Mycetophagus punctatus from Pleurotus ostreatus. Majka (2010) reported other fungal associations with this species. Adults were captured during June and August.

Most adults from New Brunswick were collected from moldy decaying corncobs and cornhusks near a mixed forest. One individual each was captured in a Lindgren funnel trap deployed in a mature hardwood forest and an old red oak forest. Adults were collected during June, August, and September.

Distribution in Canada and Alaska.

BC, AB, SK, MB, ON, QC, NB, NS (Bousquet 1991; Majka 2010). Although Mycetophagus quadriguttatus was reported as occurring in New Brunswick by Bousquet (1991), no specimens could be located to support this record according to Majka (2010). In addition, Campbell et al. (1989) did not report it for the province, and thus, Majka considered the record as provisional. However, the above records establish this species as a member of the New Brunswick Coleoptera fauna.

Majka (2010) reported Litargus tetraspilotus from deciduous, coniferous, and mixed forests, seashores, coastal and sandy pine barrens, and old fields and grasslands in Nova Scotia. Adults were collected from foliage of a variety of coniferous and deciduous tree species, herbaceous vegetation and rotting mushrooms. In New Brunswick, one adult was collected from a decaying mushroom in a conifer forest with white pine (Pinus strobus L.) and spruce, another in a Lindgren funnel trap deployed in an old red oak forest. Although this species appears to be common and widespread in the lower mainland of Nova Scotia (Majka 2010), it was found at only two localities (one specimen at each locality) in New Brunswick. Adults were captured during August in New Brunswick.

Distribution in Canada and Alaska.

Family Tetratomidae Billberg, 1820

Members of the Tetratomidae (the polypore fungus beetles), as their name implies, feed on fruiting bodies of Polyporaceae and Tricholomataceae, and are commonly found under fungus grown bark or in softer shelf fungi (Young and Pollock 2002). Adults usually feed on the surface of the fungi, whereas the larvae bore into and feed on the tissues. Majka and Pollock (2006) reviewed the Tetratomidae and other saproxylic beetles (Melandryidae, Synchroidae, Scraptiidae) of the Maritime provinces, summarized the known bionomics, and discussed the fauna in the context of potential impact that forest management practices may have on members of these families in the region. Only one species, Penthe pimelia (Fabricius) was reported as occurring in New Brunswick by LeSage (1991a) and Majka and Pollock (2006). Later, Pollock (2008) reported Pseudoholostrophus discolour (Horn) from the province. Here, we report seven additional species of Tetratomidae from New Brunswick (Table 1.). Four of these species, Tetratoma variegata Casey, Pisenus humeralis Kirby, Hallomenus serricornis LeConte, and Synstrophus repandus (Horn), are newly recorded for the Maritime provinces.

Family Melandryidae Leach, 1815

The Melandryidae (the false darkling beetles) are either xylophagous (Serropalpini and Melandryini) or fungivores (Orchesiini), although fungi may be a significant portion of the diet of the xylophagous species (Pollock 2002). Majka and Pollock (2006) reviewed the Melandryidae of the Maritime provinces, summarized the known bionomics, and discussed the fauna in the context of potential impact of forest management practices in the region. They reported 16 species from New Brunswick; Enchodes sericea (Haldeman), Prothalpia undata LeConte, and Emmesia connectens Newman were reported as new to the province. Here, we report 10 additional species for the province. Microscapha clavicornis LeConte and Zilora nuda Provancher are newly recorded for the Maritime provinces (Table 1).

Collection localities in New Brunswick, Canada of Orchesia cultriformis.

Collection and habitat data.

This species was found in various forest types in New Brunswick. These included hardwood forests with sugar maple and American beech, an old red oak stand, mixed forests, an old eastern white cedar forest/swamp, a red spruce forest, and an old red pine forest. Most adults were captured in Lindgren funnel traps. Adults with specific habitat data were collected from polypore fungi and from polypore fungi on a dead, standing American beech and a dead, standing eastern hemlock (Tsuga canadensis (L.) Carr.). One individual was collected at an ultraviolet light. This species and Orchesia castanea (Melsheimer) have an amazing jumping ability, and adults often jumped out of a 15 cm high sifting box, resulting in the loss of many specimens. Adults were collected during June, July, and August.

Distribution in Canada and Alaska.
