Material examined.

New Brunswick, Sunbury Co., McGowans Corner, Grand Lake P.N.A., 45.8959°N, 66.2823°W, 16.VI.2013, R.P. Webster // Silver maple forest, in Polyporus squamosus  (on dead standing silver maple) (1 ♂, 1 ♀, RWC).

Natural history.

Two individuals of Gyrophaena brevicollis  were collected from Polyporus squamosus  ( Polyporaceae  ) on a dead standing silver maple in a silver maple forest. One specimen from ON was collected from gilled mushrooms ( Brunke et al. (2012), otherwise little is known about the habitat association of this species.

Distribution in Canada and Alaska.

ON, NB ( Bousquet et al. 2013). Brunke et al. (2012) reported this species for the first time for Canada from several sites in southern ON.


Except for a slight difference in the shape of male tergite VIII, the NB specimen agrees with the description and illustrations in Seevers (1951) for Gyrophaena brevicollis  . We have noted that the shape of the male tergite is variable in other Gyrophaena  species ( Klimaszewski et al. 2009b).
