The Mordellidae (Coleoptera) of the Maritime provinces of Canada

  • Christopher G. Majka (a1) and John A. Jackman (a2)

The Mordellidae of the Maritime provinces of Canada is surveyed. Thirty species have now been recorded from the region. Of these, 17 are newly recorded for Nova Scotia, 11 are newly recorded for Prince Edward Island, and 7 are newly recorded for New Brunswick, for a total of 35 new provincial records. Three species, Mordellistena indistincta Smith, Mordellistena rubrifascia Liljeblad, and Mordellistena rubrilabris Helmuth, are newly recorded for Canada, while a further 11 species, Mordella melaena Germar, Mordellistena aspersa (Melsheimer), Mordellistena errans Fall, Mordellistena morula LeConte, Mordellistena picilabris Helmuth, Mordellistena sericans Fall, Mordellistena vilis (LeConte), Mordellina ancilla (LeConte), Mordellina nigricans (Melsheimer), Mordellina pustulata (Melsheimer), and Glipostenoda ambusta (LeConte), are newly recorded for Atlantic Canada. One subspecies, Mordella atrata lecontei Csiki, is removed from the region's faunal listing. The composition of the region's fauna as a whole, and related biogeographic questions, are briefly discussed. The Mordellidae are also discussed in the context of forest beetle communities in the region and the impact of historical forest management practices on old-growth specialist species.

Cet article examine le Mordellidae des provinces maritimes du Canada. À date, on a recensé trente espèces dans la région. De ces dernières, 17 ont été recensées pour la première fois en Nouvelle-Écosse, 11 à l'Île-du-Prince-Édouard et 7 au Nouveau Brunswick, pour un total de 35 espèces nouvellement recensées dans ces provinces. Trois de ces espèces, Mordellistena indistincta Smith, Mordellistena rubrifascia Liljeblad et Mordellistena rubrilabris Helmuth, ont été recensées pour la première fois au Canada, alors que 11 autres espèces, Mordella melaena Germar, Mordellistena aspersa (Melsheimer), Mordellistena errans Fall, Mordellistena morula LeConte, Mordellistena picilabris Helmuth, Mordellistena sericans Fall, Mordellistena vilis (LeConte), Mordellina ancilla (LeConte), Mordellina nigricans (Melsheimer), Mordellina pustulata (Melsheimer) et Glipostenoda ambusta (LeConte), ont été recensées pour la première fois dans les provinces atlantiques du Canada. Une sous-espèce, Mordella atrata lecontei Csiki, n'apparaît pas à la liste faunique de la région. L'article aborde brièvement l'ensemble de la composition faunique de la région et les thèmes biogéographiques sous-jacents. On aborde également le Mordellidae dans le contexte des communautés de coléoptères forestiers de la région et l'impact historique des pratiques de gestion forestière sur des espèces spécialisées qui vivent dans les forêts de peuplement mature.
