Adventive Staphylinidae (Coleoptera) of the Maritime Provinces of Canada: further contributions

Abstract

Seven species of adventive Palaearctic staphylinids, Ilyobates bennetti Donisthorpe, Meotica exilis (Knoch), Meotica "pallens" (Redtenbacher), Anotylus insecatus (Gravenhorst), Anotylus tetracarinatus Block, Oxytelus sculptus Gravenhorst, and Lathrobium fulvipenne (Gravenhorst) are newly recorded in the Maritime Provinces of Canada. One of these, M. exilis, a cosmopolitan species, is newly recorded in Canada and represents the fi rst verifi able report of this species from North America. Th e history of M. exilis in North America is examined indicating that previous reports were the result of misidentifi cation or of specimens of uncertain identity that can no longer be located. Th e confused nomenclature of this species is also discussed. Th e confused taxonomy of Meotica "pallens" is discussed with regard to the identity of the species reported under this name in North America. Atheta dadopora Th omson is newly recorded in Prince Edward Island. Records are provided that establish the presence of L. fulvipenne in North America in fi ve Canadian provinces. Observations on A. insecatus in the fi eld have established that they are predators of dipteran larvae. New early dates of detection are reported for Quedius curtipennis Bernhauer, Tasgius ater (Gravenhorst), Philonthus cognatus Stephens, and Philonthus rectangulus Sharp. As a consequence, 87 species of adventive Staphylinidae are now known to occur in the Maritime Provinces, 76 of which have been recorded in Nova Scotia, 61 in New Brunswick, and 29 on Prince Edward Island. Th e staphylinid fauna is briefl y discussed in relation to its zoogeographic components and its regional composition.

Pella glooscapi, a new rove beetle, and new records of aleocharines from Nova Scotia, Canada (Coleoptera, Staphylinidae)

“…Dalotia coriaria is the 88 th species of adventive staphylinid to be recorded in the Maritime Provinces, and the 77 th from Nova Scotia (Majka and Klimaszewski 2008b). Th e very high proportion of adventive species found in this region is apparent when one considers that of the 38 adventive aleocharines recorded by Gouix and Klimaszewski (2007) in Canada and Alaska, 31 (82%) are found in the Maritime Provinces.…”

“…Previously Majka and Klimaszewski (2008a) reported Drusilla canaliculata (Fabricius, 1787) from Nova Scotia and Majka and Klimaszewski (2008b) added Xenodusa refl exa (Walker) to the provincial list. Drusilla canaliculata is a suspected myrmycophage while X. refl exa is a myrmecophile; both are members of the Lomechusini.…”

Two new species and new provincial records of aleocharine rove beetles from Newfoundland and Labrador, Canada (Coleoptera, Staphylinidae, Aleocharinae)

“…In New Brunswick, this adventive species was collected in litter at the base of a tree in a silver maple swamp, in flood debris along a river margin, and among decaying corncobs and cornhusks near a home in a forested residential area (Webster et al 2009). Majka and Klimaszewski (2008) reported this species from pitfall traps in pastures and a blueberry field in Nova Scotia. In Europe, this species has been reported from similar habitats (Assing 1999).…”

Majka and Klimaszewski (2008d) reported this species from pitfall traps in pastures and a blueberry fi eld in Nova Scotia.
