Notes.

Mycetophagus quadriguttatus Müller is newly recorded in Nova Scotia (Fig. 1). The species was reported from New Brunswick by Bousquet (1991), however, I have not been able to locate a voucher specimen for this record; it is not present in the CNC nor was it reported from New Brunswick by Campbell et al. (1989). Pending confirmation its status in New Brunswick should be regarded as provisional. In Nova Scotia, one specimen was collected in a grist mill and another in a compost heap. Campbell et al. (1989) reported the species in waste feed, sacked grain, grain elevators, warehouses, flour mills, old flour barrels, fungi at the base of old hay stacks, fungi on trees, a vegetable store, and a corn shop.

Although Hatch (1962) thought it was probably an introduced species, other investigators ( Parsons 1975; Bousquet 1991; Downie and Arnett 1996) have classified it as a native Holarctic species. Mycetophagus quadriguttatus is widely distributed in Europe having been reported throughout the continent except for Corsica, Crete, Cyprus, Estonia, Ireland, Norway, Portugal, and Sicily ( Nikitsky 2010), and is also found across North Africa, in the eastern Palaearctic, Asia, and Australia ( Nikitsky 2010).
