Fifty-four new Canadian provincial records of aleocharine beetles (Staphylinidae), including three new Canadian records and one new North American record, are presented. Of these, 33 are new provincial records for Saskatchewan, 14 for Alberta, two for British Columbia, three for Manitoba, two for the Northwest Territories and one for the Yukon Territory. The following are new Canadian records: Trichiusa pilosa Casey [formerly reported from Nova Scotia and Ontario as T. postica Casey], Acrotona recondita (Erichson) and the adventive Palaearctic Atheta nigra (Kraatz), which is also a new North American record. Bionomics information and new locality records are provided. The following new synonyms of Trichiusa pilosa Casey are established: T. atra Casey, T. monticola Casey, T. parviceps Casey, and T. postica Casey. The numbers of Aleocharinae remaining to be discovered in Canadian provinces and territories are discussed.

Staphylinidae (the rove beetles) are the most species-rich family of beetles in Canada with 1652 species and subspecies recorded, 510 of which are in the Aleocharinae (
All specimens in this study were dissected to examine the genital structures. Extracted genital structures were dehydrated in absolute alcohol, mounted in Canada balsam on celluloid micro-slides, and pinned with the specimens from which they originated. Images of the entire body and the genital structures were taken using an image processing system (Nikon SMZ 1500 stereoscopic microscope; Nikon Digital Camera DXM 1200F, and Adobe Photoshop software).

Our knowledge of the diversity and distribution of Aleocharinae in Canada has increased rapidly over the last ~25 years, faster than for other subfamilies of rove beetles and for most (perhaps all) families of beetles. This increase in knowledge is attributed to a surge in sampling of this subfamily, particularly in eastern Canada, and to a large amount of taxonomic activity (e.g., by Gusarov, Lohse, Klimaszewski, Webster). Of the 463 native species of Aleocharinae recorded in Canada by
Despite the great improvements in taxonomic knowledge and availability of diagnostic resources (keys, illustrations, expertly identified reference material), sampling of most of the microhabitats and regions of the country is still woefully incomplete. In recent years, thanks to very active sampling in the Atlantic provinces (especially New Brunswick and Newfoundland and Labrador) and in the Yukon Territory, coupled with large efforts to identify material and publish findings (

Estimating the expected number of species of aleocharines in Canada is challenging. One way to do this is to extrapolate based on the species richness patterns for the family Carabidae (ground beetles) that is very well known and surveyed throughout most of Canada. This family frequently co-occurs with aleocharines, especially in epigaeic and saproxylic habitats. The jurisdictions where the aleocharine fauna is best known are Yukon Territory, New Brunswick and Newfoundland and Labrador. For Carabidae, the fauna of these three jurisdictions represent 20.5%, 34.3%, and 19.5% of the total number (972) of carabid species/subspecies in Canada (
The expected species richness of aleocharines for each jurisdiction can also be estimated using the proportion of the total Canadian carabid fauna in each territory and province and multiplying that against the expected total Canadian aleocharine species richness (707) (Table

In Alberta, adults were collected using window traps attached to a girdled white spruce tree and a snag, and were reared from white spruce logs in early and intermediate decay stages. In Quebec, adults were found in dead and dying black spruce (Picea mariana Mill. (BSP)) in black spruce dominated stands. The adults were collected from June to September.

In Alberta, one female was collected using a window trap deployed in a 10-year-old regenerating white spruce stand. The British Columbia specimens were found on bison scat. The adults were collected from June to September.
The two specimens from British Columbia agree with the type series in external morphology and shape of genitalia except for the entirely black body. It is well known that many aleocharine species exhibit darker colour at higher latitudes compared with more southern populations.
