New Staphylinidae (Coleoptera) records with new collection data from New Brunswick, Canada: Pselaphinae.

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; , ), Wagner (1975), Chandler (1986; , ), Carlton and Chandler (1994; ), Chandler (1990; , ), Grigarick and Schuster (1971; , ), Chandler (1986, 1993; ), Chandler (1991; ), Chandler (1989) PageBreakand Carlton (2003; ), Park (1947; ), Fall (1927; ), Carlton (1989; ), Park (1958; ), Casey (1894; , ), and Chandler (1999; ). 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 (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 s, , and were dissected in order to confirm their identity. The genital structures were dehydrated in absolute alcohol and either mounPageBreakted 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:

Acronyms of collections examined or where specimens referred to in this study reside are as follows:

Collection and habitat data.

Wagner (1975) recorded this species from under bark of pine ( sp.). Chandler (1990) reported that this species was associated with dead pine trees in Latimer Co., Oklahoma, as well as being collected from an oak ( sp.) tree hole, old sawdust, under bark, and at the base of a standing dead pine (Chandler 1997). In New Brunswick, adults were captured in Lindgren funnel traps deployed in an old (180-year-old) red pine ( Ait.) forest and an old (180-year-old) mixed forest with various conifer species including red and white pine ( L.). Adults were captured during June, July, and August.

Park et al. (1950) reported from a sugar maple ( 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 ( Ehrh.) and sugar maple. Wagner (1975) considered this species to be the most frequently collected 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 ( L.) forest, an old silver maple ( 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.
