Records of adventive aleocharine beetles (Coleoptera: Staphylinidae: Aleocharinae) found in Canada

Abstract

Eight additional adventive aleocharine beetles, native to the Palaearctic region, are reported from Canada, five of them for the first time. They belong to three tribes: Crataraea suturalis (Mannerheim) (Nova Scotia, Saskatchewan, British Columbia) and "Meotica pallens (Redtenbacher)" (Ontario, British Columbia) belong to Oxypodini; Atheta (Chaetida) longicornis (Gravenhorst) (Nova Scotia, Quebec), Atheta (Thinobaena) vestita (Gravenhorst) (New Brunswick), Dalotia coriaria (Kraatz) (Alberta), Dinaraea angustula (Gyllenhal) (Nova Scotia, Prince Edward Island, Quebec, Alberta), and Nehemitropia lividipennis (Mannerheim) (New Brunswick, Nova Scotia, Prince Edward Island, Quebec, Ontario) belong to Athetini; and Homalota plana (Gyllenhal) (Nova Scotia, New Brunswick) belongs to Homalotini. These species have likely been introduced into Canada from Europe by various anthropogenic activities, and their bionomics and possible modes of introduction are discussed. For each species, a short diagnosis and habitus and genital images are provided to assist with identification. The habitus and genital images are presented here for the first time for these species in North America. New United States records are not included in the abstract. 79Résumé-Huit espèces additionnelles de coléoptères aleocharines, originaires de la région Paléarctique, sont rapportées pour le Canada, parmi lesquelles cinq sont mentionnées pour la première fois. Elles appartiennent aux trois tribus suivantes : Oxypodini (2 espèces) -Crataraea suturalis (Mannerheim) (Nouvelle-Écosse, Saskatchewan, Colombie-Britannique), « Meotica pallens (Redtenbacher) » (Ontario, Colombie-Britannique); Athetini (5 espèces) -Atheta (Chaetida) longicornis (Gravenhorst) (Nouvelle-Écosse, Québec), Atheta (Thinobaena) vestita (Gravenhorst) (Nouveau-Brunswick), Dalotia coriaria (Kraatz) (Alberta), Dinaraea angustula (Gyllenhal) (Nouvelle-Écosse, Île-du-Prince-Édouard, Québec, Alberta), Nehemitropia lividipennis (Mannerheim) (Nouvelle-Écosse, Île-du-Prince-Édouard, Nouveau-Brunswick, Québec, Ontario); and Homalotini (1 espèce) -Homalota plana (Gyllenhal) (Nouvelle-Écosse, Nouveau-Can.

New Staphylinidae (Coleoptera) records with new collection data from New Brunswick, Canada. I. Aleocharinae

“…Flying individuals were collected with a net between 15:00 and 16:00 h during warm afternoons in early spring. In other areas, A. longicornis has been found associated with dung and various rotting organic materials (Klimaszewski et al 2007a Klimaszewski et al (2006). Adults were collected in May and July.…”

New records of Canadian Aleocharinae (Coleoptera, Staphylinidae)

“…Th is species is associated with dung and decaying organic matter. North American specimens have been found on cow dung and pig carrion (Klimaszewski et al 2007a). Atheta dadopora is newly recorded in Alberta, Ontario, and Alaska.…”

“…In the Old World it is widely distributed across Europe, east through western and eastern Siberia (Smetana 2004). It is found in un-forested, arable land; in Canada it has been found in or adjacent to agricultural fi elds (Klimaszewski et al 2007a). …”

“…In the Old World it is widely distributed across Europe, North Africa, and Asia including eastern and western Siberia (Smetana 2004). In Nova Scotia H. plana has been found in sub-cortical environments under the bark of white pine (Pinus strobus L.) between December and early May where it is active on sunny days when the sun warms this micro-environment (Klimaszewski et al 2007a). Klimaszewski & Pelletier, 2004 CANADA: ALBERTA: no locality noted, 30.V.1995, H.E.J.…”
