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.
Staphylinidae, Pselaphinae, new records, Canada, New Brunswick
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
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 (
Over 710 species of Pselaphinae are known from North America (
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 methodsVarious collection methods were employed to collect the species reported in this study. Details are outlined in
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.
DistributionDistribution 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 |

Collection localities in New Brunswick, Canada of Decarthron abnorme.
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 (

Collection localities in New Brunswick, Canada of Reichenbachia corporalis.
In New Brunswick, adults of this species were collected in old eastern white cedar swamps and forests, silver maple swamps, a red spruce forest, a mixed forest, a Carex marsh, and a seasonally flooded marsh. Adults were sifted from leaf and/or conifer litter at the bases of trees, from sphagnum and grasses under alders and on hummocks near vernal pond margins, in moist leaf litter under Myrica gale L. bushes, and from leaf litter and moss near brook margins. One adult was collected in an ultraviolet light trap and another from a Lindgren funnel trap. Members of this species have been taken from sphagnum moss and from leaf litter of an alder/birch (Betula sp.) mixture at the edge of a freshwater marsh (

In New Brunswick, this species was collected from a variety of wetland types. These include a tamarack bog, a black spruce bog, an old eastern white cedar swamp, Carex marshes, and an old beaver (Castor canadensis Kuhl) flowage with grasses. Adults occurred in sphagnum hummocks in bogs, in moss and litter at bases of trees, in litter and sphagnum in marshes, and in grass litter near a brook in an old beaver flowage. One individual was captured in a Lindgren funnel trap deployed in an old red oak forest.
