Abstract

Twenty species of Pselaphinae are newly recorded from New Brunswick, Canada. This brings the total number of species known from the province to 36. Thirteen of these species are newly recorded for the Maritime provinces of Canada. Dalmosella tenuis Casey and Brachygluta luniger (LeConte) are newly recorded for Canada. Collection and habitat data are presented for these species.

Introduction

This paper treats new Staphylinidae records from New Brunswick from the subfamily Pselaphinae. Taxonomically, the North American species of Pselaphinae are fairly well known. Most species in the Maritime provinces (New Brunswick, Nova Scotia, Prince Edward Island) of eastern Canada can be determined using keys and descriptions in Grigarick and Schuster (1980; Bibloporus, Dalmosella), Wagner (1975), Chandler (1986; Euplectus, Pycnoplectus), Carlton and Chandler (1994; Ramecia), Chandler (1990; Bibloplectus, Trimioplectus), Grigarick and Schuster (1971; Actiastes, Actium), Chandler (1986, 1993; Actizona), Chandler (1991; Lucifotychus), Chandler (1989) and Carlton (2003; Reichenbachia), Park (1947; Batrisodes), Fall (1927; Rybaxis), Carlton (1989; Eutrichites), Park (1958; Decarthron), Casey (1894; Brachygluta, Pselaphus), and Chandler (1999; Tyrus). Chandler (1997) summarized information on biology and taxonomy of the North American species and noted availability of keys to genera in his catalog.

Species of Pselaphinae from eastern Canada are found in moss, grass, and leaf litter in marshes, bogs, and along stream margins, the intertidal zone of salt marshes, forest floor litter, in rotten logs, under bark of dead trees and logs, in tree holes, and in ant nests (Park 1947, 1949; Park et al. 1950; Reichle 1969; Wagner 1975; Chandler 1987, 1989, 1991, 1993, 1997). Adults are predators of mites, Diptera larvae, earthworms, ant eggs and larvae, collembolans, and other small invertebrates (Park 1929, 1932a, 1932b, 1947; Grigarick and Schuster 1971; Chandler 1997, 2000). Some species may be important as indicators of old-growth forests (Chandler 1987; Carlton and Chandler 1994).

Over 710 species of Pselaphinae are known from North America (Chandler 1997). Eighty-five species were reported from Canada by Davies (1991), with 15 of these recorded from New Brunswick. Majka and Ogden (2006) reported Brachygluta abdominalis (Aubé) new to NS and NB, and to Canada. Here, we report 21 species new to New Brunswick, including two species new to Canada.

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 the by-catch of samples obtained during a study to develop a general attractant for the detection of invasive species of Cerambycidae.

Collection methods

Various collection methods were employed to collect the species reported in this study. Details are outlined in Campbell (1973) and Webster et al. (2009, Appendix). See Webster et al. (2012) 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 the collection and habitat data section for each species.

Specimen preparation

Males of Actiastes, Euplectus, and Pycnoplectus were dissected in order to confirm their identity. The genital structures were dehydrated in absolute alcohol and either mounted in Canada balsam on celluloid microslides and pinned with the specimens from which they originated, or glued onto points with the specimens.

Distribution

Distribution maps, created using ArcMap and ArcGIS, are presented for each species in New Brunswick. Every species treated has its currently known distribution in Canada and Alaska indicated, using standard two-letter abbreviations for the states, provinces, and territories. New records for New Brunswick are indicated in bold under Distribution, which covers 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
BC British Columbia PE Prince Edward Island
AB Alberta NS Nova Scotia
SK Saskatchewan NF & LB Newfoundland and Labrador

Collection and habitat data.

Park et al. (1950) reported Euplectus confluensfrom a sugar maple (Acer saccharum Marsh.) tree hole. According to Wagner (1975), the preferred habitat of this species was loose, moist, decayed woody debris in hollow trees and basal tree holes in American beech (Fagus grandifolia Ehrh.) and sugar maple. Wagner (1975) considered this species to be the most frequently collected Euplectus species in eastern deciduous forests. Chandler (1997) reported that this species was most commonly found in tree holes and rotten wood, but was also taken from barn debris and sawdust and at an ultraviolet light. In New Brunswick, adults were captured in Lindgren funnel traps deployed in an old red oak (Quercus rubra L.) forest, an old silver maple (Acer saccharinum L.) swamp, and an old mixed forest. Basal tree holes were frequent in the red oak and the mixed forest stand. Adults were captured during June, July, and August.

In New Brunswick, this common species was collected in various wetland habitats. These included Carex marshes, Carex marsh with scattered cattails (Typha sp.), a cattail marsh, a black spruce (Picea mariana (Mill.) B.S.P.) and tamarack (Larix laricina (Du Roi) K. Koch) bog, a coastal raised peatland with black spruce, an old eastern white cedar swamp, a regenerating mixed forest, along a lake margin among Carex, and in a wet alder (Alnus sp.) swamp. Adults were sifted from moss and litter at bases of trees and marsh margins, sphagnum and leaf litter, and leaf and grass litter on hummocks (alder swamp). Other adults were collected by treading vegetation in cattail and Carex marshes, Carex near Myrica bushes on a lake margin, and a saturated sphagnum mat in bog. Some adults were collected at an ultraviolet light near a mixed forest. This species is most commonly taken from leaf litter along the margins of streams, ponds, and marshes, and from sphagnum moss (Chandler 1997). Adults were captured during late March, April, May, June, July, and September.
