A synopsis of adventive species of Staphylinidae (Coleoptera) in Canada is provided. Of the over 1654 rove beetle species recorded from Canada, 156 species in 76 genera and 13 subfamilies are reported as adventive, constituting about 9.4% of the fauna. The majority of adventive species belong to two subfamilies, Staphylininae (51 species) and Aleocharinae (49), and the genera with the most species are Philonthus (16), Atheta (8), Aleochara (7) and Quedius (7).
All 156 adventive species are reviewed, including diagnostic features (supported by 156 colour habitus photos and 230 black and white images of diagnostic characters), native range, detailed distribution in Canada (with 151 distribution maps), general distribution in the USA, early Canadian and North American records and habitat information. New jurisdictional records are Atheta longicornis (Gravenhorst) from Alberta, Philonthus sanguinolentus (Gravenhorst) from eastern Canada (Ontario) and Xantholinus longiventris Heer from Canada (British Columbia).
