This species is newly recorded in Nova Scotia. In Canada it has been recorded in the Northwest Territories, from Saskatchewan east to New Brunswick, and in Newfoundland ( Bousquet 1991). In the United States, Chandler (1991) reported it from New Hampshire and Downie and Arnett (1996) reported it south to New York and west to Michigan. The distribution in the Maritime Provinces is shown in Figure 1 .

Some species of Lasconotus are known scolytine predators, although early larval instars retain the fungivorous habit ( Hackwell 1973). Most species in the Synchitini are associated with rotting wood and bark or fungus-ridden duff. Adults and larvae feed on fungal masses or fruiting bodies of both Ascomycetes and Basidomycetes or on rotting plant material containing fungi ( Ivie 2002).
