The weevils (Coleoptera: Curculionoidea) of the Maritime Provinces of Canada, II: New records from Nova Scotia and Prince Edward Island and regional zoogeography

Abstract

Seventy-nine species of weevils are newly reported in Nova Scotia and 66 species are newly reported on Prince Edward Island, increasing the known provincial weevil faunas to 244 and 92 species, respectively. Thirty-six species are recorded for the first time in the Maritime Provinces; of these, Ceutorhynchus pallidactylus (Marsham), Listronotus dietzi O'Brien, Corthylus columbianus Hopkins, and Orchidophilus aterrimus (Waterhouse) are recorded for the first time in Canada. Orchidophilus aterrimus has been collected only in exotic domesticated orchids and is not established in the wild. Fourteen species previously recorded on Cape Breton Island, Nova Scotia, are reported from the provincial mainland. Four species — Curculio sulcatulus (Casey), Ceutorhynchus squamatus LeConte, Tachyerges niger (Horn), and Ips calligraphus (Germar) — are removed from the faunal list of Nova Scotia, and three species — Temnocerus cyanellus (LeConte), Curculio nasicus (Say), and Cryphalus ruficollis ruficollis Hopkins — are removed from the faunal list of Prince Edward Island. The combined known weevil fauna of the Maritime Provinces now totals 290 species. The adequacy of collection effort is discussed and in Nova Scotia, where collection effort has been greatest, distribution patterns of selected groups of species are examined. Island faunas are discussed with respect to those of Prince Edward Island and Cape Breton Island. Regional biogeographic patterns of species are also discussed, including possible disjunct populations in Nova Scotia and species that may not have crossed the isthmus of Chignecto to colonize Nova Scotia. Attention is drawn to the long history of introduced species in the region and to ongoing introductions through an examination of the earliest records for the 60 introduced species found in the region.

Saproxylic beetle (Coleoptera) communities and forest management practices in coniferous stands in southwest Nova Scotia, Canada

“…Both studies thus contribute to ongoing programs to document the distribution, abundance, origins, and trophic categories of the beetle fauna of the province which are essential for many ecological, zoogeographic, and environmental monitoring studies (McCorquodale et al 2005). Some specimens derived from this study have already contributed to recent surveys of the Coleoptera fauna of the region (Bousquet and Laplante 2006;Majka , 2006bMajka , 2007aMajka , 2007cMajka , 2008aCline 2006a, 2006b;Majka and Johnson 2008;Majka and Pollock 2006;Majka et al , 2007aMajka et al , 2007a). …”

First Record ofPolydrusus sericeus(Schaller) (Coleoptera: Curculionidae) in Western North America

“…With the exception of blueberries, all of the crops and trees in the immediate vicinity of the find have been previously recorded as food plants for adult P. sericeus in North America or Europe (Majka et al 2007;Coyle et al 2008). Neither the hazelnut orchard nor the birch stand in the United States could be accessed.…”
