New Coleoptera records from eastern Canada, with additions to the fauna of Manitoba, British Columbia, and Yukon Territory.

Abstract

One-hundred-eleven new provincial and territorial Coleoptera records are reported from New Brunswick (64), Nova Scotia (20), Prince Edward Island (5), Quebec (14), Manitoba (3), British Columbia (3), and Yukon Territory (2) for the 26 following families: Carabidae, Dytiscidae, Histeridae, Staphylinidae, Scarabaeidae, Buprestidae, Eucnemidae, Elateridae, Cantharidae, Erotylidae, Monotomidae, Cryptophagidae, Passandridae (first record of this family from New Brunswick), Laemophloeidae, Nitidulidae, Anamorphidae, Coccinellidae, Latridiidae, Mordellidae, Tenebrionidae, Cerambycidae, Chrysomelidae, Anthribidae, Brentidae, Dryophthoridae, and Curculionidae. Among these are ten new Canadian records: Heterosternutaoppositus (Say, 1823) (Dytiscidae) (New Brunswick), Gyrophaenablatchleyi Seevers, 1951 (Staphylinidae) (Quebec), Acropteroxyslecontei Crotch, 1873 (Erotylidae) (Manitoba), Placonotusfalinorum Thomas, 2011 (Laemophloeidae) (Quebec), Adelina pallida (Say, 1824) (Tenebrionidae) (Quebec), Poeciloceraharrisii (J.L. LeConte, 1851) (Chrysomelidae) (New Brunswick), Plesiobarisalbilata (LeConte, 1876) (Curculionidae) (Quebec, New Brunswick), Pseudopityophthorusasperulus (LeConte, 1868) (Curculionidae) (Nova Scotia), Hylurgopspalliatus (Gyllenhal, 1813) (Curculionidae) (New Brunswick), and Heteroboripsseriatus (Blandford, 1894) (Curculionidae) (Nova Scotia). Plesiobarisdisjuncta Casey reported as new for Canada in New Brunswick and Quebec by Webster et al. (2012a) is actually P.albilata (LeConte) and thus P.disjuncta is removed from the faunal list of Canada. Eleven species from New Brunswick not previously reported in literature were found on the online platforms BugGuide.Net and iNaturalist and are reported in this publication. This highlights the importance of online platforms dedicated to recording wildlife observations and citizen science in detecting new species records. Data is also presented for seven species from Quebec and two species from New Brunswick reported by Bousquet et al. (2013) without any supporting information for their occurrence in these provinces. Among the species reported here, 32 are adventive.
