Abstract

Forty-four species of Staphylininae are newly reported from New Brunswick, bringing the total number of species known from the province to 126. Quedius criddlei (Casey) is reported for the first time from Quebec. Bisnius cephalotes (Gravenhorst) is removed from the faunal list of New Brunswick due to a lack of supporting voucher specimens. Additional locality data are presented for seven species either recently recorded from the province or with few previous records and little habitat data. We provide the first documented records of Atrecus americanus (Casey), Quedius erythrogaster Mannerheim, Quedius labradorensis labradorensis Smetana, Quedius plagiatus (Mannerheim), and Neobisnius terminalis (LeConte) from New Brunswick. Collection and habitat data are presented and discussed for all species.

Introduction

Intensive collecting of rove beetles (family Staphylinidae) in New Brunswick by the first author since 2003 has yielded many new provincial and national records. Additional records were obtained from by-catch samples during a study to develop a general attractant for detecting invasive species of Cerambycidae. These records are being published in a series of papers, each focusing on one or more subfamilies of Staphylinidae and other families of Coleoptera. This paper covers the subfamily Staphylininae.

This subfamily is fairly well known taxonomically in Canada and North America, thanks to various revisions. The genera Erichsonius and Neobisnius were revised by Frank (1975, 1981), respectively. The Xantholinini were revised by Smetana (1982, 1988), the Quediina by Smetana (1965, 1971a, 1971b, 1973, 1976, 1978, 1981, 1990), the Philonthina by Smetana (1995), and the Staphylinina by Brunke et al. (2011). As a result of these revisions, our knowledge of the distribution of these species in Canada was also greatly increased.

Adults of Staphylininae live in a wide variety of habitats. Many species live in and near wetlands, including river and brook margins, lakeshores, vernal pool and pond margins, bogs, marshes, sea beaches, and various synanthropic situations (Smetana 1971a, 1982, 1995). Depending on species, adults usually occur in leaf litter, sphagnum moss, and other kinds of debris in these wetland habitats, but some species are highly hygrophilic and occur in floating mats of moss or vegetation (Smetana 1971a, 1982, 1995). Other species are associated with decaying organic materials, including compost, decaying mushrooms, animal droppings, and carcasses. Some species are regular inhabitants of bird and mammal nests. Philonthus janus Smetana, Philonthus couleensis Hatch, and Quedius campbelli Smetana are commonly found in North American beaver (Castor canadensis Kuhl) lodges and muskrat (Ondatra zibethicus (L.)) nests, but these associations are not strict, and these species can also be found in adjacent wetland habitats (Smetana 1995). However, a few species such as Heterothops marmotae Smetana and Bisnius lautus (Casey) have much stronger associations (Smetana 1971b, 1995). These species live in underground burrows of rodents and are rarely found in other habitats. Most species are probably general predators (Smetana 1995), although additional research is required to elucidate the biology of most members of this subfamily.

Campbell and Davies (1991) reported 27 species of Staphylininae for New Brunswick. The number of species recorded from the province was increased to 77 species as a result of revisions by Smetana (1995), and new additions to the fauna by Klimaszewski et al. (2005), Majka and Smetana (2007), Majka and Klimaszewski (2008a, b), Majka et al. (2009), Majka and Brown (2010), and Smetana and Webster (2011). Majka et al. (2011) reported Atrecus americanus (Casey), Quedius erythrogaster Mannerheim, Quedius labradorensis labradorensis Smetana, Quedius plagiatus (Mannerheim), and Neobisnius terminalis (LeConte) as occurring in New Brunswick but did not provide any supporting references or data for the records. Here, we report an additional 44 species of Staphylininae for New Brunswick, bringing the total number of species known for the province to 126 (Table 1).

Notes: *New to province; **New to Maritime provinces

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. Additional provincial records were obtained from specimens contained in the collection at Natural Resources Canada’s Atlantic Forestry Centre in Fredericton, New Brunswick.

Collection methods

Various collection methods were employed to collect the Staphylininae reported in this study. Details are outlined in Campbell (1973) and Webster et al. (2009, Appendix). Many 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 detecting 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). Traps were suspended from rope tied between two trees separated by at least 2 m, with the collecting cup 30–50 cm above the ground. Collecting cups contained either a 50:50 mixture of propylene glycol and deionized water plus 0.5 ml/L of Kodak Photo-Flo 200 and 12.5 mg/L of Bitrex (in 2008) or a saturated salt solution with 1–2 drops of unscented dish detergent (in 2009 and 2010). Traps were baited with various lures reported as pheromones for longhorn species in the Cerambycinae subfamily (racemic 3-hydroxyhexan-2-one or racemic 3-hydroxyoctan-2-one) (Allison et al. 2004; Hanks et al. 2007) and/or high-release-rate ethanol lures (ConTech, Inc, Delta, BC), or were left unbaited. The effects of lure treatment on attraction (capture in Lindgren traps) of Staphylininae species and other by-catch species will be reported in separate papers. Samples were collected once weekly (2008 and 2009) or once every 2 weeks (2010), and specimens frozen until they were processed. 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 the collection and habitat data section for each species.

Specimen preparation

Examples of most species of Staphylininae were dissected to confirm their identity. The genital structures were dehydrated in absolute alcohol, mounted in Canada balsam on celluloid microslides, and 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:

Results

Forty-four species of Staphylininae are newly recorded from New Brunswick; Bisnius cephalotes (Gravenhorst) is removed from the faunal list of New Brunswick because of lack of a supporting voucher specimen. We provide the first documented records of Atrecus americanus (Casey), Quedius erythrogaster Mannerheim, Quedius labradorensis labradorensis Smetana, Quedius plagiatus (Mannerheim), and Neobisnius terminalis (LeConte) from New Brunswick. This brings the total number of species known from the province to 126 (Table 1). Thirty-three of these species are newly recorded for the Maritime provinces (New Brunswick, Nova Scotia, Prince Edward Island) of Canada. Additional locality data are presented for seven species either recently recorded from the province or having few previous records and little bionomic data. Quedius criddlei (Casey) is reported for the first time from Quebec.

Collection and habitat data.

The single New Brunswick specimen was collected from sphagnum in a forested black spruce (Picea mariana (Mill.) B.S.P.) bog. Elsewhere this species has been reported from forest litter and from wet moss and debris in wet habitats, such as swamps, marshes, bogs, and lake and stream margins (Smetana 1982). The single adult was collected by sifting sphagnum during late April.

Collection and habitat data.

Smetana (1982) reported this species from under bark of dead trees with one record from Fomitopsis pinicola (Swartz: Fr.) Karst. In New Brunswick, this species was found in various forest types, including hardwood, mixed red spruce (Picea rubens Sarg.) and eastern white cedar (Thuja occidentalis L.), and old-growth hemlock (Tsuga canadensis (L.)). Adults were found under bark of both dead hardwood and conifer trees, in rotten logs, and in various species of polypore fungi (fleshy and bracket fungi). One adult was found in moss on a rock along a shaded brook. Adults were collected during May, June, July, August, and September.

Collection and habitat data.

Little is known about the habitat assciations of members of this genus, especially in North America (Smetana 1982). Species from the Palaearctic have been collected from hollows of trees and stumps and in litter at bases of dead trees; some species occur regularly in bird nests in hollow trees and are often observed among ants (Smetana 1982). In New Brunswick, one specimen was collected from the nest contents of a barred owl (Strix varia Barton), one from under the bark of a large, dead, fungus-covered basswood (Tilia americana L.) log, and another from a Lindgren funnel trap deployed in mature (old) red oak (Quercus rubra L.) forest. One specimen was collected in association with an ant, Formica subsericea Say, in Iowa City, Iowa (Smetana 1982). Adults were collected during May and September.

Collection and habitat data.

Smetana (1971a, 1976) reported this species from swampy and marshy areas, and along lake and bog margins. Adults occurred in wet moss, wet sphagnum, floating sphagnum mats, leaves and debris, and other floating vegetation. In Nova Scotia, adults were collected in a eutrophic, Typha latifolia L. marsh (Smetana 1965). In New Brunswick, this species was found in marsh vegetation or saturated sphagnum hummocks along a marshy stream margin near a forested black spruce bog, a tamarack (Larix laricina (Du Roi) Koch) bog, a beaver pond, and in Carex marshes. Most adults were collected by treading vegetation into water. Adults were collected in April, May, June, and July.

Distribution in Canada and Alaska.

ON, QC, NB, NS (Smetana 1971a, 1973, 1976). Smetana (1990) reported Acylophorus caseyi from western Maine near the border with New Hampshire (Wilsons Mills Bog, Oxford Co.). The above record from Maine represents a significant eastern range extension in the state. It is apparent from the above records that Acylophorus caseyi probably has a more continuous distribution in the Northeast and the Maritime provinces as a whole than was suggested by the collection records reported in Majka et al. (2009). These distributional gaps likely reflect incomplete collecting effort in the appropriate wetland habitats. One must use treading to collect this species from the wetland habitats that this species usually frequents.

Collection and habitat data.

Hemiquedius feroxwas reported by Smetana (1971a) from various wet habitats, such as swamps, lake margins, and marshes. Adults were found in wet moss and leaves and in beaver lodges in late fall. Adults were found in similar habitats in New Brunswick, including an alder swamp, silver maple (Acer saccharinum L.) swamps, pond margins, a seasonally flooded marsh, a gravel bar on river, and a beaver lodge. Adults occurred in moss and Carex hummocks, in leaf litter along vernal pond margins and within the wall of a beaver lodge. Adults were collected by sifting litter and moss or treading vegetation into water. One individual was collected in a Lindgren funnel trap. Adults were captured during May, June, July, August, and September.

Collection and habitat data.

Little is known about the habitat associations of this species. Smetana (1973) reported a specimen from Polyporus betulinus (Bull.) Fr. In New Brunswick, one specimen was collected from under bark of a large, dead, standing basswood covered with bracket fungi (polypore fungi), one from under bark of a spruce log, and another in a polypore fungi on a Populus log. Many specimens were captured in Lindgren funnel traps deployed in a variety of forest types, including an old red pine (Pinus resinosa Ait.) forest, a hardwood with sugar maple (Acer saccharum Marsh.) and American beech (Fagus grandifolia Ehrh.), an old-growth northern hardwood forest, a red spruce forest, an old-growth white spruce and balsam fir forest, a mixed forest, and an old eastern white cedar forest. These traps mimic tree trunks (Lindgren 1983), and it is possible that this species lives in microhabitats associated with standing trees. Adults were collected in April, May, June, July, August, and September.

Collection and habitat data.

Quedius erythrogastertypically lives in nests and burrows of various mammals and in caves but has been found in decaying organic matter and debris (Smetana 1971a), including wet leaf litter (Smetana 1976). In New Brunswick, adults were found in leaf litter early in the season when snow was still present (possibly an overwinter site), compost (decaying vegetables), and decaying mushrooms. Other adults were collected from the nest contents of a barred owl in a tree hole, suggesting this species may also live in association with tree-cavity-nesting birds. Adults were also captured in Lindgren funnels traps deployed in an old red oak forest, an old red pine forest, and an old-growth northern hardwood forest.

Collection and habitat data.

In Europe, this species is typically found in synanthropic situations in decaying organic materials such as compost (Smetana 1971a). It has also been reported from mammal burrows, tree holes, and caves in natural settings. In New Brunswick, adults were collected from under bark of a fungus-covered, dead, standing basswood, among moist wood chips and decaying plant material, and from Lindgren funnel traps deployed in a hardwood forest and an old-growth white spruce and balsam fir forest. Adults were captured in June, July, September, and October.

Collection and habitat data.

One of the Nova Scotia specimens was collected by treading wet Sphagnum (Smetana 1973), otherwise little is known about the habitat associations of this species (Smetana 1971a). Specimens from New Brunswick were collected in red oak and red maple forests, a red spruce and red maple forest, an old sugar maple and American beech forest, and regenerating mixed forests. Adults were collected from gilled mushrooms, a decayed fleshy polypore fungus on a log, from a rotten fungus-covered log, baited with decaying mushrooms, sifted from sphagnum and leaf litter at bottom of old tire depression, and swept from foliage in a regenerating forest. Adults were also captured in pitfall traps in large numbers (Klimaszewski et al. 2005). This species is probably associated with decaying organic matter, such as decaying mushrooms. Adults were captured during July, August, September, and October.

Collection and habitat data.

This species has been reported mostly from around human settlements in various kinds of debris and under stones (Smetana (1971a). Adults have also been found in natural habitats in moss and leaf litter (Smetana 1971a, 1978). In New Brunswick, adults were collected in natural habitats (river margin in litter, in moist leaf litter and moss on vernal pond margin in a hardwood forest) and in synanthropic situations (in compost and pile of decaying corncobs and cornhusks near a home). Adults were collected in April, May, June, August, and September.

Collection and habitat data.

Smetana (1976) reported this species from moss, mushrooms, and deciduous leaf litter (birch and poplar stands) near streams. In the Alberta foothills forests, Quedius labradorensis was considered to be an open-ground specialist after forest harvesting and only extended a short distance into adjacent uncut forests (Pohl et al. (2007). Numbers of this species also increased after harvesting. In New Brunswick, most adults were found in old-growth eastern white cedar swamps in moss usually near small streams. One adult was found under white-tailed deer (Odocoileus virginianus (Zimmerman)) dung, and another was collected at a mercury-vapor light. Adults were collected during April and May.

Collection and habitat data.

In Europe, Quedius cinctususually occurs in decaying organic material, usually near human settlements (Smetana 1971a). In New Brunswick, specimens were similarly found in decaying organic material (decaying mushrooms, decaying corncobs and cornhusks, decaying leaves). One individual was found in wet moss along a cold, shaded brook. Adults were collected in April, July, September, and October.

Distribution in Canada and Alaska.

ON, NB (Majka et al. 2009; Brunke and Marshall 2011). This adventive species was first reported from New Brunswick and Canada by Majka et al.

Collection and habitat data.

Relatively little was previously known about the habitat requirements of this species, although it appears that this species may be associated with moss and leaf litter near small streams and other wetlands. Smetana (1973, 1976) reported the species from leaf litter in a sphagnum bog, wet sphagnum (treading) along the margin of a large spring, and in leaf litter (sifting) along a small stream. In the Alberta Foothills forests, Quedius frigidus was considered to be a mature forest specialist (Pohl et al. 2007). Adults at the three New Brunswick localities were found in moss and leaf litter near brooks in old-growth eastern white cedar forests and a mature spruce and balsam fir forest on the north-facing slope of a hill. Adults were collected during May and June.

Distribution in Canada and Alaska.

AK, NT, ON, NB, NF (Smetana 1973, 1976, 1978, 1981). Smetana (1971a, 1973) suggested that Quedius frigidus was a northern transcontinental species with glacial relic populations in southern areas at higher mountain elevations. The New Brunswick records indicate a more southerly distribution at low elevations in eastern Canada.

Collection and habitat data.

Brunke et al. (2011) reported that Staphylinus ornaticauda was restricted to wetlands, such as bogs and fens, with an abundance of sphagnum moss. In New Brunswick, this species appears to be associated with eastern white cedar swamps and fens and red maple swamps on calcareous soils. Adults were collected in eastern white cedar swamps, an eastern white cedar, red maple, and black ash (Fraxinus nigra Marsh.) swamp, and in a red maple swamp near an eastern white cedar swamp. Adults occurred in litter at the base of cedars, and in moist litter and moss near small vernal pools with Carex. Adults were collected by sifting litter. This species was collected in April, May, and June. This species is flightless (Brunke et al. 2011). Due to the limited dispersal capabilities, restricted habitat requirements, and apparent rarity, Brunke et al. (2011) suggested that this species should be studied as a potential species at risk.

Distribution in Canada and Alaska.

Collection and habitat data.

This species was reported by Smetana (1995) from various habitats associated with trees, such as swallow nests, old squirrel nests, and a red oak tree fork hole. In New Brunswick, all but one of the Bisnius palmi specimens were found in the nest contents of a great horned owl (Bubo virginianus Gmelin) and barred owls, which normally nest in tree holes or in artificial nest boxes on trees. This species was also found in the nest contents of a red shouldered hawk (Buteo lineatus Gmelin), which makes large nests within forks of large trees. One adult was captured in a Lindgren funnel trap deployed in the canopy of a red oak in an old red oak forest. Adults were collected in May, June, July, and September.

Distribution in Canada and Alaska.

ON, NB, NS (Smetana 1995). Bisnius palmi is transcontinental in North America, with most records from eastern North America. There is one record from Nova Scotia (Caribou Island). Bisnius palmi was originally described from Sicily, Italy, but was apparently an accidental, introduced specimen (Smetana 1995).

Webster, mixed forest, Lindgren funnel trap (1 ♂, RWC).

Collection and habitat data.

Little is known about the habitat associations of this species. Smetana (1995) speculated that it might live in burrows of mammals or, less likely, in bird nests. Two specimens from New Brunswick were found in moss at the base of a tree in an old-growth eastern white cedar swamp early in the season when some snow and ice were still present. This was possibly an overwintering site. Most specimens were captured in Lindgren funnel traps deployed in a variety of forest types (red pine, red oak, red spruce, mixed forest, old-growth northern hardwood forest). These traps mimic tree trunks (Lindgren 1983), and it is possible that this species lives in microhabitats associated with standing trees. Adults were collected in April, May, June, and July.

Distribution in Canada and Alaska.

QC, NB (Smetana 1995). This rare species was known from only a few localities in Quebec south to Massachusetts and west to Michigan, Kansas, and South Dakota (Smetana 1995).

Collection and habitat data.

Erichsonius alumnus appears to be a riparian species associated with river and brook margins. Records in Frank (1975) included individuals from banks of streams, on mud by a brook, and an individual collected by treading mud by a stream. In New Brunswick, the largest series was collected along a river margin under debris on a sand–clay mix. Other adults were collected from brook margins in alder swamps and a beaver meadow. Adults occurred in grass litter mixed with fine gravel and clay, among cobblestones and gravel, and leaf and grass litter from these brook margin habitats. This species was collected in May and June.

Collection and habitat data.

Little was previously known about the habitat associations of this species. The only records with habitat data reported in Frank (1975) included specimens sifted from flood debris, swamp grass, ex nest of a meadow vole (Microtus pennsylvanicus Ord), and one individual collected in a tamarack bog. In New Brunswick, this species appears to be associated with moist to wet habitats in forested areas, including seepage areas near small brooks, vernal pond margins, stream and river margins, and Carex marsh. Adults were sifted from moist leaves, grass litter on muddy soil, drift material, and by treading Carex. A few adults were sifted from leaf litter from the crotch of a silver maple with multiple trunks in early April in a silver maple swamp. This was presumably an overwintering site for these adults. Adults were collected during April, May, June, and July.

Collection and habitat data.

In Europe, adults of this adventive species occur in wet habitats, marshes, swamps, margins of streams and ponds, and swampy meadows; it is found in similar habitats in North America (Smetana 1995). In New Brunswick, most adults were found along lake, pond, brook, and river margins, usually in leaf litter or drift material. Others were found in an eastern white cedar swamp in moist sphagnum, in a dried vernal pond in sphagnum and leaf litter. Klimaszewski et al. (2005) reported specimens from pitfall traps deployed in a red spruce stand (Acadia Research Forest). Adults were collected in March, April, May, June, July, and September.

Collection and habitat data.

Smetana (1995) reported that this species typically occured under bark of both deciduous and coniferous species and was often associated with old trees. Adults occur in debris under bark, in rotting wood, and in wood and debris around the bases of dead standing trees. This species has also been found in rotting mushrooms and forest floor litter and has been taken in flight intercept traps (Smetana 1995). In New Brunswick, this species was found in similar habitats, including under bark of American beech, red maple, red oak, red spruce, and from the nest contents of a barred owl. Adults were also collected in Lindgren funnel traps and in flight during evening flights. Adults were captured during April, May, June, and August.

Collection and habitat data.

Philonthus subvirescens is a riparian species found on sandy and gravel margins in areas with sparse vegetation (Smetana 1995). This species was found among gravel and flood debris along the margins of small fast-flowing rivers in New Brunswick.

Distribution in Canada and Alaska.

AK, YT, NT, BC, AB, QC, NB (Smetana 1995). Philonthus subvirescens is a Holarctic species with a mostly western distribution from Alaska and the Northwest Territories south to the mountains of California and east to New Mexico, with a significantly disjunct population in Quebec on the Gaspé Peninsula (Smetana 1995). The presence of this species in northwestern New Brunswick indicates that this species has a somewhat wider distribution in easternmost Canada.

Webster, in flood debris on upper river margin (1 ♂, 1 ♀, RWC).

Collection and habitat data.

This species has been found in open, often dry habitats with sandy substrates (open pine forests) and in moist to wet habitats near water, such as sandy creek, river, and pond margins (Smetana 1995). Adults occurred in leaf litter and debris. Specimens were also found in entrances of Marmota burrows (Smetana 1995). In New Brunswick, this species was found in silver maple floodplain forests, a hardwood forest on an island in a large river, and on an upper river margin. Adults were collected from leaf litter from a crotch of a silver maple with multiple trunks, litter at the base of a tree, in flood debris, and from Pleurotus mushrooms on a log.

Distribution in Canada and Alaska.

AB, SK, MB, ON, QC, NB (Smetana 1995). Philonthus thoracicus was previously known from New Brunswick from one specimen collected by G.A. Calderwood in the Kouchibouguac National Park (Smetana 1995). It is apparent from the above records that this species is more widely distributed in the Maritime provinces than was suggested by the distributional gaps shown in Majka et al. (2009). Floodplain forests should be sampled for this species in Nova Scotia.

Collection and habitat data.

This species occurs in moist to wet habitats such as marshes, swamps, marshy margins of lakes and ponds, and in muskrat nests. Adults have been collected by treading vegetation (floating sphagnum mats, sedges and mosses, Typha plants, reeds) into water (Smetana 1995). In New Brunswick, adults were collected by treading vegetation along a beaver pond margin, from under drift material on a lake margin, sifting leaf litter in a silver maple swamp, and in flight during evening. Adults were collected in May and June.
