Abstract
The Mycetophagidae (hairy fungus beetles) of the Maritime Provinces of Canada are surveyed. Seven species in the genera Mycetophagus, Litargus, and Typhaea are found in the region. Six new provincial records are reported including Mycetophagus punctatus and Mycetophagus flexuosus, whichare newly recorded in the Maritime Provinces. The distribution of all species is mapped, colour habitus photographs of all species are figured, and an identification key to species is provided. The discussion notes that four of the species found in the region are apparently rare, possibly due to the history of forest management practices in the region; a situation similar to that of a significant proportion of other saproxylic beetles found in the Maritime Provinces.
Highlights
The Mycetophagidae are a family of relatively small, fungus-eating beetles
Mycetophagus flexuosus Say is newly recorded in the Maritime Provinces from New Brunswick; Mycetophagus punctatus Say is newly recorded in the Maritime Provinces from Nova Scotia; Mycetophagus serrulatus Casey is newly recorded in New Brunswick; Mycetophagus pluripunctatus LeConte is newly recorded in New Brunswick; Mycetophagus quadriguttatus Müller is newly recorded in Nova Scotia; and Litargus tetraspilotus LeConte is newly recorded in Prince Edward Island – a total of five new provincial records, two of which are newly recorded in the region
Mycetophagus quadriguttatus Müller is newly recorded in Nova Scotia (Fig. 1)
Summary
The Mycetophagidae (hairy fungus beetles) are a family of relatively small, fungus-eating beetles. Five genera and 26 species are known in North America, 15 of which have been recorded in Canada (Bousquet 1991; Young 2002). Parsons (1975) provided the most recent species-level taxonomic revision of the family. Mycetophagus quadriguttatus Müller and Typhaea stercorea (Linnaeus), have previously.
