Map 5. Collection localities in New Brunswick, Canada of Mycetophagus quadriguttatus . Collection and habitat data. Most adults from New Brunswick were collected from moldy decaying corncobs and cornhusks near a mixed forest. One individual each was captured in a Lindgren funnel trap deployed in a mature hardwood forest and an old red oak forest. Adults were collected during June, August, and September. Distribution in Canada and Alaska. BC, AB, SK, MB, ON, QC, NB, NS ( Bousquet 1991 ; Majka 2010 ). Although Mycetophagus quadriguttatus was reported as occurring in New Brunswick by Bousquet (1991) , no specimens could be located to support this record according to Majka (2010) . In addition, Campbell et al. (1989) did not report it for the province, and thus, Majka considered the record as provisional. However, the above records establish this species as a member of the New Brunswick Coleoptera fauna.
