Abstract

This paper treats 134 new records of Coleoptera for the province of New Brunswick, Canada from the following 41 families: Gyrinidae, Carabidae, Dytiscidae, Histeridae, Leiodidae, Scarabaeidae, Scirtidae, Buprestidae, Elmidae, Limnichidae, Heteroceridae, Ptilodactylidae, Eucnemidae, Throscidae, Elateridae, Lampyridae, Cantharidae, Dermestidae, Bostrichidae, Ptinidae, Cleridae, Melyridae, Monotomidae, Cryptophagidae, Silvanidae, Laemophloeidae, Nitidulidae, Endomychidae, Coccinellidae, Corylophidae, Latridiidae, Tetratomidae, Melandryidae, Mordellidae, Tenebrionidae, Mycteridae, Pyrochroidae, Aderidae, Scraptiidae, Megalopodidae, and Chrysomelidae. Among these, the following four species are newly recorded from Canada: Dirrhagofarsus ernae Otto, Muona & McClarin (Eucnemidae), Athous equestris (LeConte) (Elateridae), Ernobius opicus Fall (Ptinidae), and Stelidota coenosa Erichson (Nitidulidae). The Family Limnichidae is newly reported for New Brunswick, and one species is added to the fauna of Nova Scotia. Stephostethus productus Rosenhauer (Latridiidae), Tetratoma (Abstrulia) variegata Casey (Tetratomidae), and Chauliognathus marginatus (Fabricius) (Cantharidae) are removed from the faunal list of New Brunswick, and additional records of Lacconotus punctatus LeConte (Mycteridae) are presented and discussed. Lindgren funnel traps provided specimens for 104 (78%) of the species and were the sole source of specimens for 89 (66%) of the species reported here, suggesting they are a very useful tool for sampling Coleoptera fauna in the forests of New Brunswick.

Introduction

In recent years, the Coleoptera of New Brunswick has been studied intensively. In a series of papers published in a Special Issue of ZooKeys (179) on the biodiversity and ecology of the Coleoptera of New Brunswick, Canada, edited by Robert Anderson and Jan Klimaszewski, 320 species of Coleoptera were newly reported from the province in the following 59 families: Gyrinidae, Carabidae, Dytiscidae (Webster and DeMerchant 2012a); Histeridae (Webster et al. 2012c); Geotrupidae, Scarabaeidae (Webster et al. 2012e); Eucinetidae, Scirtidae (Webster et al. 2012f); Buprestidae (Webster and DeMerchant 2012b); Dryopidae, Elmidae, Psephenidae, Ptilodactylidae (Webster and DeMerchant 2012c); Eucnemidae (Webster et al. 2012g); Elateridae (Webster et al. 2012h); Lycidae (Webster et al. 2012i); Dermestidae, Endecatomidae, Bostrichidae, Ptinidae (Webster et al. 2012s); Trogossitidae, Cleridae, Melyridae (Webster et al. 2012j); Silvanidae, Laemophloeidae (Webster et al. 2012k); Sphindidae, Erotylidae, Monotomidae, Cryptophagidae (Webster et al. 2012l); Kateretidae, Nitidulidae, Cerylonidae, Endomychidae, Coccinellidae, Latridiidae (Webster et al. 2012m); Mycetophagidae, Tetratomidae, Melandryidae (Webster et al. 2012n); Mordellidae, Ripiphoridae (Webster et al. 2012o); Tenebrionidae, Zopheridae (Webster et al. 2012q); Stenotrachelidae, Oedemeridae, Meloidae, Mycteridae, Boridae, Pythidae, Pyrochroidae, Anthicidae, Aderidae (Webster et al. 2012p); Cerambycidae (Webster et al. 2012r); Megalopodidae, Chrysomelidae (Webster et al. 2012b); Anthribidae, Brentidae, Dryophthoridae, Brachyceridae, Curculionidae (Webster et al. 2012a). In these papers, new habitat and biological data were presented for many of the species, as well as an updated list of the species from each family known to occur in New Brunswick. Recently, Pelletier and Hébert (2014) reviewed the Cantharidae of eastern Canada and reported 19 species new to New Brunswick. Most recently, Webster et al. (2016) newly reported an additional 16 species of Cerambycidae for the province. These baseline biodiversity data are important for documentation of changes in our ecosystems due to human intervention and climate change.

During the last several years, additional new provincial records have been accumulated from the families Gyrinidae, Carabidae, Dytiscidae, Histeridae, Leiodidae, Scarabaeidae, Scirtidae, Buprestidae, Elmidae, Limnichidae, Heteroceridae, Ptilodactylidae, Eucnemidae, Throscidae, Elateridae, Lampyridae, Cantharidae, Dermestidae, Bostrichidae, Ptinidae, Cleridae, Melyridae, Monotomidae, Cryptophagidae, Silvanidae, Laemophloeidae, Nitidulidae, Endomychidae, Coccinellidae, Corylophidae, Latridiidae, Tetratomidae, Melandryidae, Mordellidae, Tenebrionidae, Mycteridae, Pyrochroidae, Aderidae, Scraptiidae, Megalopodidae, and Chrysomelidae. The purpose of this paper is to report these new records.

Methods and conventions

Collection methods. Various methods were employed to collect the specimens reported in this study. Details are outlined in Webster et al. (2009, Appendix) and Webster et al. (2012d). Many specimens were from Lindgren funnel trap samples from a study to improve methods for survey and detection of exotic and potentially invasive bark and wood-boring beetles (Cerambycidae and Curculionidae). These traps are visually similar to tree trunks and are often effective for sampling species of Coleoptera that live in microhabitats associated with standing trees (Lindgren 1983). Between 2009 and 2015, Lindgren funnel traps were deployed at 27 sites (24–64 traps per site). At many sites, starting in 2012, traps were deployed in the upper canopy as well as in the understory, usually in equal numbers, although at a few sites only canopy traps or understory traps were used. Canopy traps were 10–20 m above the ground, whereas understory traps were 1–1.5 m above the ground (i.e., 30–50 cm from the bottom of the collecting cup to the ground). In both cases, traps were suspended from rope such that the trap was at least 1 m from the main stem of trees and at least 30 m from another trap. Traps were baited with various combinations of lures for detecting Cerambycidae. However, data on attractants were not collected for non-target species. See Webster et al. (2012r), Hughes et al. (2014), and Webster et al. (2016) for additional details of the lures and methods used to deploy Lindgren traps and collect samples. A description of the habitat was recorded for all specimens collected during this survey. Locality and habitat data are presented as on labels for each record. Two labels were used on many specimens: one that included the locality, collection date, and collector, and one with macro- and microhabitat data and collection method. Information from the two labels is separated by a double slash (//) in the data presented from each specimen.

Specimen preparation and determination. Males of some species were dissected to confirm their identities. The genital structures were dehydrated in absolute alcohol and either mounted in Canada balsam on celluloid microslides or glued onto cards that were then pinned with the specimen from which they originated. Most specimens reported in this study were determined by the senior author using various keys to the families or genera treated in this publication. Some specimens in the families Ptinidae, Cryptophagidae, and Melyridae were compared to specimens from the Canadian National Collection (CNC) to confirm their names. A number of species in the families Scarabaeidae, Elateridae, Buprestidae, Dermestidae, Ptinidae, Elateridae, Melyridae, Mordellidae, Tenebrionidae, and Chrysomelidae were determined by curators at the CNC.

Results and discussion

In this account, we newly report 133 species and one new subspecies from NB. Four of these species are new for Canada. Additional records are given for the rarely collected Lacconotus punctatus LeConte (Mycteridae). One species is newly recorded from NS. Eighty-nine of the new records were collected exclusively from Lindgren funnel traps as part of a study to improve methods for survey and detection of exotic and potentially invasive bark and wood-boring beetles (Cerambycidae, Curculionidae). Another 15 species were detected using both Lindgren funnel traps and other sampling methods. The above data indicate that Lindgren traps are a very useful tool for sampling Coleoptera fauna in the forests of NB. Thirty-two species were found using methods such as litter sampling, light trapping, or use of an aquatic dip net. Below, we present the details of the new records.

Species accounts

All records below are species newly recorded for NB or NS, Canada, unless noted otherwise (additional records). Species indicated by a † are adventive to Canada; species with a * are Holarctic; species with a ‡ are either adventive or Holarctic. The determination that a species was a new record is based on information in the print version of Bousquet et al. (2013). The family-level classification used below follows Bouchard et al. (2011).

Suborder Adephaga

Family Dytiscidae Leach, 1815

Webster (2008) reviewed the Dytiscidae of NB, adding 18 species to the faunal list. Another species was added by Webster and DeMerchant (2012a). Below, three more dytiscid species are newly reported for the province.

Comments

Larson et al. (2000) mentioned that Copelatus glyphicus (Say) was abundant during early August in gravel pit pools and tire ruts in peaty soils in NS and NB. However, this species was not listed as occurring in NB in the checklist of the species occurring in Canada (Table 1, p. 15) and there are no dots on the distribution map for this species in the province (Map 2, p. 52) in Larson et al. (2000). The records above confirm the presence of this species in NB. All specimens from NB were captured in Lindgren funnel traps.

Comments

Dirrhagofarsus ernae was recently described from OH, in the USA and occurs from NH, west to WI, south to MO, AL and VA (Otto et al. (2014). According to Otto et al. (2014), the sudden appearance of this species in the USA suggests that it may be an introduction to North America, possibly a previously unknown species from Asia. In NB, no specimens were encountered prior to 2013 despite intensive sampling with Lindgren funnel traps at many sites, including Odell Park, where it was first encountered during 2013. It is possible that D. ernae is a recent arrival to NB.

Comments

Athous equestris occurs from NJ, west to SD and KS, south to GA and MS in the USA and was considered rare by Becker (1974). Its presence in NB is a surprise, as the closest known locality is in NJ.

Lloyd (2002) provided an overview of the taxonomy, classification, and biology of the Lampyridae of North America. Later, Luk et al. (2011) provided a key to the species of Lampyridae of ON that is applicable to all species occurring in eastern Canada. The Lampyridae of Atlantic Canada were subsequently reviewed by Majka (2012), adding three new species for NB. Using the key by Luk et al. (2011), we identified specimens of Photinus aquilonius Lloyd and P. ignitus Fall from material originally determined as P. ardens LeConte. Both species are new to NB.

Chauliognathus marginatus (Fabricius, 1775) and C. pensylvanicus (DeGeer, 1774)

Chauliognathus marginatus (Fabricius) was reported from NB by Bousquet et al. (2013). This species is known only from extreme southern ON in Canada (Pelletier and Hébert 2014). We were not able to find any records of this species from NB. Interestingly, C. pensylvanicus (Fabricius), a common and widespread species in NB, was not included for the province by Bousquet et al. (2013). We assume that C. marginatus was included for NB instead of C. pensylvanicus (DeGeer) in error. In view of this, C. marginatus is removed from the faunal list of NB. Pelletier and Hébert (2014) provide supporting data for the occurrence of C. pensylvanicus in NB.

Superfamily Bostrichoidea Latreille, 1802

Webster et al. (2012s) reviewed the Dermestidae, Endecatomidae, Bostrichidae, and Ptinidae fauna of NB and newly reported two species of Dermestidae, two Bostrichidae, and five species of Ptinidae. The family Endecatomidae was reported for the first time for the province on the basis of Endecatomus rugosus (Randall). Here, three new Dermestidae, one new Bostrichidae, and 20 new Ptinidae are added to the faunal list for the province. One of these, Ernobius opicus Fall, is a new to Canada. Two of the three species of Dermestidae and all but one of the 20 species of Ptinidae were first detected using Lindgren funnel traps and nearly all specimens of these species were caught in these traps.

Interestingly, this species was not detected at the Bell Forest or other sites in NB prior to 2012, possibly because sampling was not done using Lindgren traps in the canopy of trees before 2012.

Comments

Two subspecies of Thanasimus undatulus (Say), T. undatulus undatulus and T. undatulus nubilus (Klug), co-occur at many sites in NB. The two subspecies differ in overall coloration, color pattern, and size. Thanasimus u. undatulus is black with the basal third of pronotum red-brown, and the white posterior band on elytra continues as a narrow band along the suture to near or to the posterior margin of the elytra. The average length is smaller: from 5.2 to 6.8 mm. Thanasimus u. nubilus is black, without red-brown areas on the pronotum and elytra, and there is little or no extension of the white posterior band along the suture toward elytral apex (body length 6.2 to 9.3 mm). We have not seen any intermediate specimens. More studies are required to establish if these two subspecies should be treated as distinct species.

Comments

All specimens of C. pilosa reported from NB were captured in Lindgren funnel traps. At sites (seven of eight sites where species was detected) where both high (canopy) and low traps were tested, C. pilosa was captured exclusively in traps deployed in the canopy of trees. This species was captured in low traps at only one site (Eel River P.N.A.). At this site, canopy traps were not used, and the four specimens were captured in traps along the edge of an open fen.

Comments

This adventive Palaearctic species was previously known only from NF (St. John’s) in North America and occurs in various habitats including stored produce in Europe (Woodroffe and Coombs 1961, Johnson et al. 2007, Klimaszewski et al. 2015). Specimens from NB were captured in Lindgren funnel traps and sifted from a pile of moldy decaying corncobs and cornhusks.

Comments

Atomaria lederi Johnson was first reported for North America by Johnson et al. (2007) without supporting data. Majka et al. (2010) provided supporting data for Johnson’s record and additional locality and habitat data from NS for the presence of A. lederi in Canada and North America. This species is widespread in NS and was found mostly in red spruce (Picea rubens Sarg.) and red spruce–eastern hemlock (Tsuga canadensis (L.) Carr.) forests (Majka et al. 2010). New Brunswick specimens were collected from Lindgren funnel traps in a mixed forest, jack pine (Pinus banksiana Lamb.) forest, red oak (Quercus rubra L.) forest, old-growth white spruce (Picea glauca (Moench) Voss) and balsam fir (Abies balsamea (L.) Mill.) forest, and a red spruce forest with some red maple (Acer rubrum L.) and balsam fir. Bousquet et al. (2013) considered the status of A. lederi in North America as uncertain and that the species could either be adventive to North America or Holarctic. Klimaszewski et al. (2015) treated A. lederi as an adventive Palaearctic species. Given that this species was collected in natural habitats throughout NB and NS suggests it could be a Holarctic species that has been undetected in Canada and North America until recently.

Comments

The adventive C. turcicus is considered a serious pest of flour and feed mills and is sometimes found in grain elevators and warehouses (Bousquet 1990). Specimens from NB were captured in Lindgren funnel traps in an old white pine (Pinus strobus L.) stand, mixed forest with red oak, and a mixed forest. This stored product pest is not normally associated with natural habitats. Several poultry farms occur in the vicinity of the sites, and it is likely that these were dispersing individuals from these farms. Interestingly, two other stored product pests, C. pusillus Schönherr and A. advena were also collected at one of these sites.

Adults of S. coenosa were collected from partially dried bolete mushrooms on a roadside through a jack pine forest. Little is known about the habitat requirements of this species. Other species in the genus have been found in decaying fruit and fungi (Downie and Arnett 1996). Most members of the genus are tropical (Ford 1996). In the United States, S. coenosa (as S. ferruginea Reitter) has been recorded from NJ west to MI, south to FL and TX (Downie and Arnett 1996).

Family Latridiidae Erichson, 1842

Webster et al. (2012m) newly recorded nine species of Latridiidae for NB in their review of this family. Klimaszewski et al. (2015) noted that the specimen reported as Stephostethus productus Rosenhauer by Webster et al. (2012m) was misidentified. Details on this are provided below.

Subfamily Latridiinae Erichson, 1842

Stephostethus productus Rosenhauer, 1856

The specimen of S. productus reported from Tracy, NB as a new Canadian record by Webster et al. (2012m) was misidentified and was Latridius hirtus Gyllenhal. Stephostethus productus is accordingly removed from the faunal list of Canada and NB. However, L. hirtus is a new record for NB.

Tetratoma (Abstrulia) variegata Casey, 1900

Tetratoma variegata Casey was newly recorded for NB by Webster et al. (2012n). Re-examination of these specimens and additional specimens from two new sites, in reference to the descriptions of T. variegata and T. canadensis Nikitsky and Chantal in Nikitsky (2004), revealed that the original determination by Webster was incorrect and that these were T. canadensis. Tetratoma variegata is therefore removed from the faunal list of NB. Tetratoma canadensis is a new provincial record and details are provided below.

Subfamily Melandryinae Leach, 1815

Thirteen species of Tenebrionidae were newly reported for NB by Webster et al. (2012q). Platydema exacavtum (Say) was removed from the list of Tenebrionidae known from NB, and the presence of P. americanum Laporte and Brullé was confirmed. Later, Bousquet and Bouchard (2014), in a review of the Paratenetus of North America, described P. exutus Bousquet and Bouchard from Tabusintac, NS (should be NB), and included many localities for this species from the province. Here, we add Cynaeus angustus (LeConte) and the adventive Gnathocerus cornutus (Fabricius) to the faunal list of the province.

Comments

Pollock and Majka (2012) reviewed the Nearctic Lacconotus and provided new data on distribution and habitat associations of L. punctatus. They showed that L. punctatus is more widespread in eastern North America than previously known. Lacconotus punctatus was reported from mixed forests, an oak savanna, and mature bottomland hardwood forests (Pollock and Majka 2012, Ulyshen et al. 2010). In NB, this species was found in similar forest types, including a hardwood bottomland woodland, a hardwood bottomland forest on an island, a Populus balsamifera stand near a river, mixed forests with red oak, a red oak forest, and an oak forest near a seasonally flooded marsh. Webster et al. (2012p) reported specimens from a bottomland (silver maple forest), a red oak forest, and a mature red spruce forest with scattered red maple. Most adults were collected early in the season from late May to mid-June, with a few captured as late as early August. Lacconotus punctatus was found at seven new localities in NB and appears to be widespread in the province.

All specimens from NB were captured in Lindgren funnel traps, showing the effectiveness of these traps for detecting this rare species. Interestingly, all but four of the 48 adults of L. punctatus were captured in the canopy of trees. In a mature bottomland hardwood forest in GA, five of six specimens were captured in flight intercept traps 15 m above the forest floor early in the season (Ulyshen et al. (2010). They suggested that L. punctatus might be a canopy and early seasonal specialist and the reason why this species is infrequently collected. Our data support their conclusion.

Webster et al. (2012p) newly recorded three species of Pyrochroidae [Neopyrochroa femoralis (LeConte), Pedilus canaliculatus (LeConte), P. elegans (Hentz)] for NB. Here, we add Dendroides testaceus LeConte to the faunal list of the province.

Dendroides testaceus is readily separated from the similar D. concolor by possessing piceous pigmentation areas on the wings; in D. concolor the pigmentation areas of wings are testaceous (Young 1975).

Family Aderidae Csiki, 1909

The Aderidae occurring in NB were reviewed by Webster et al. (2012p). They newly reported three species for the province. Here, we report the adventive Aderus populneus (Creutzer) and the native Vanonus calvescens Casey for the first time for NB. All specimens were captured in Lindgren funnel traps.

The Megalopodidae and Chrysomelidae occurring in NB were reviewed by Webster et al. (2012b). Zeugophora varians Crotch was newly recorded for NB and represented the first record of the Megalopodidae for the province. They also newly recorded 28 species of Chrysomelidae for the province. Here, we add another three species of Megalopodidae, all captured in Lindgren funnel traps in the canopy of trees, and nine species of Chrysomelidae.

The adventive B. villosus (broom seed beetle) was first reported in Atlantic Canada from NS by Majka and Langor (2011). In NS, this adventive Palaearctic species was found on the adventive weed, Scotch broom (Cytisis scoparius (L.) Link) (Fabaceae) (Majka and Langor 2011). In NB, B. villosus was swept from foliage and flowers of Lathyrus japonicus Willid. (beach pea), a native member of the Fabaceae, and from foliage in a meadow, and along a roadside at two inland sites where beach pea and Scotch broom do not occur. More study is required to establish if B. villosus will become a pest on native Fabaceae.

Comments

Poison ivy, Toxicodendron radicans (L.) Kuntze, has been reported as the preferred host for this species (see Clark et al. (2004) for a complete list of references). This vine was common at the site where the NB specimen was collected. P. tridens was thought to be restricted to the Carolinian Life Zone in Canada, and records from MB and QC were considered questionable by Barney et al. (2013). This distinctive species has not been collected in Canada since 1950 and was considered to be extirpated from Canada by Barney et al. (2013). The record from NB indicates that the species is still present in Canada.
