Henoticus serratus is newly recorded in insular Newfoundland and Nova Scotia (Fig. 1). Downie and Arnett (1996) reported the species from Labrador, although it is not clear where this record originates. Bousquet (1991) reported the species from Alaska and British Columbia east to Québec, and Downie and Arnett (1996) reported records from a variety of eastern and western states in the USA. In the Palearctic region this Holarctic species is found throughout Europe (except for the Iberian peninsula, the southern Balkans and the Mediterranean islands) southeast to Georgia, and east across Siberia to the Russian Far East (Johnson et al. 2007). All the specimens collected in Atlantic Canada are from wild habitats such as red spruce and red oak (Quercus rubra L., Fagaceae) forests. Blatchley (1910) reported it from dry fungi about the stumps of oaks. Bousquet (1989) noted that adults in the genus Henoticus are usually found in leaf litter, fungi, under the bark of dead or dying trees, and on leaves of trees or shrubs.
