Webster, under bark of wind-fallen Populus grandidentat a Michx. (4, DHWC ). Placusa canadensis is newly recorded in the Maritime Provinces. In Canada it has been previously recorded in Ontario and Québec ; in the United States it is known from Ohio and West Virginia ( Klimaszewski et al. 2001 ). In Québec this species has been found predominantly in sugar maple ( Acer saccharum Marsh. ) stands, occasionally in white spruce ( Picea glauca (Moench) Voss ) forests. Th ey have been collected from under the bark of recently fallen trees and from rotting fungi and tree stumps ( Klimaszewski et al. 2001 ). Th e specimens in Nova Scotia were found in association with specimens of Carpophilus sayi Parsons [ Nitidulidae ] (abundant), and Corticeus tenuis (LeConte) [ Tenebrionidae ] (infrequent) in the same subcortical habitat.
