Abstract 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.

Distribution. 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 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).

Family Scirtidae Fleming, 1821

The Eucinetidae and Scirtidae of NB were reviewed by Webster at al. (2012f). They added five species of Scirtidae to the faunal list of the province, including Sarabandus robustus (LeConte), which was newly recorded for Canada. Here, we add Sacodes thoracica (Guérin-Méneville) to the provincial list.

Nine species of Buprestidae were added to the faunal list of NB by Webster and DeMerchant (2012b) in their review of this family for the province. Recently, Lewis (2015) newly reported Buprestis consularis Gory. We add another seven species to the faunal list in this publication. Most of the new records were detected using Lindgren funnel traps.

Comments.

This species has been treated by some authors as a subspecies of Agrilus politus (Say), which uses various willow (Salix) species as larval hosts (Paiero et al. 2012). Larvae of Agrilus pseudocoryli Fischer, in contrast, have been recorded from American hazelnut (Corylus americana Walter) and beaked hazelnut (Corylus cornuta Marsh.) (Paiero et al. 2012). Specimens from NB were collected on the foliage of beaked hazelnut. We have found specimens of Agrilus politus in NB on the foliage of willow, and they have a slightly differently shaped aedeagus from those of Agrilus pseudocoryli.

Superfamily Byrrhoidea Latreille, 1804

Family Elmidae Curtis, 1830

One species of Elmidae, Promorensia elegans (LeConte), was added to the NB faunal list by Webster and DeMerchant (2012c) in their review of the NB members of the family. Here, we add Dubiraphia minima Hilsenhoff and Dubiraphia vittata (Melsheimer).

Family Lampyridae Rafinesque, 1815

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 Photinus ignitus Fall from material originally determined as Photinus ardens LeConte. Both species are new to NB.

Tribe Chauliognathini LeConte, 1861

Chauliognathus marginatus (Fabricius, 1775) and Chauliognathus 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, Chauliognathus pensylvanicus (Fabricius), a common and widespread species in NB, was not included for the province by Bousquet et al. (2013). We assume that Chauliognathus marginatus was included for NB instead of Chauliognathus pensylvanicus (DeGeer) in error. In view of this, Chauliognathus marginatus is removed from the faunal list of NB. Pelletier and Hébert (2014) provide supporting data for the occurrence of Chauliognathus 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.

Comments.

Two subspecies of Thanasimus undatulus (Say), Thanasimus undatulus undatulus and Thanasimus undatulus nubilus (Klug), co-occur at many sites in NB. The two subspecies differ in overall coloration, color pattern, and size. Thanasimus undatulus 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 undatulus 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.

Adults of Stelidota 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, Stelidota coenosa (as Stelidota ferruginea Reitter) has been recorded from NJ west to MI, south to FL and TX (Downie and Arnett 1996).

Family Endomychidae Leach, 1815

Webster et al. (2012m) newly recorded Hadromychys chandleri Bousquet and Leschen and Danae testacea (Ziegler) for NB in their review of the NB members of the family. Here, we add two Symbiotes species to the faunal list. Both species were captured exclusively in Lindgren funnel traps.

Family Corylophidae LeConte, 1852

The classification, taxonomy, and biology of the North American species of Corylophidae (minute hooded beetles or minute fungus beetles) were reviewed by Bowestead and Leschen (2002). Members of this family are often found on leaves and flowers, in leaf litter, grass piles, under bark, and sometimes in bird and caterpillar nests where the adults and larvae feed on fungal spores (Bowestead and Leschen 2002). Majka and Cline (2006) reviewed the Corylophidae of the Maritime Provinces and reported three species from NB, including Orthoperus suturalis LeConte and Rypobius marinus LeConte, which were new to the province. Bousquet et al. (2013) included another species on the faunal list of NB, Clypastraea lugubris (LeConte), in the most recent checklist of the Coleoptera of Canada. In this publication, we newly record five species of Corylophidae for NB.

Comments.

Pollock and Majka (2012) reviewed the Nearctic Lacconotus and provided new data on distribution and habitat associations of Lacconotus punctatus. They showed that Lacconotus 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 Lacconotus 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 Lacconotus punctatus might be a canopy and early seasonal specialist and the reason why this species is infrequently collected. Our data support their conclusion.

Comments.

Dendroides testaceus is readily separated from the similar Dendroides concolor by possessing piceous pigmentation areas on the wings; in Dendroides 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.
