Abstract: | 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 Trichiusa
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: Trichiusa
atra Casey, Trichiusa
monticola Casey, Trichiusa
parviceps Casey, and Trichiusa
postica Casey. The numbers of Aleocharinae remaining to be discovered in Canadian provinces and territories are discussed. |
