Tachyporus ornatus Campbell, 1979

Materials.

CANADA: ON: Wellington Co., Belwood Lake, lake margin, fallen log overhang, 3-VI-2008, S.A. Marshall (1).

Diagnosis.

Tachyporus ornatus can be distinguished from all other large northeastern members of the genus except Tachinus lecontei ,by the combination of a non-bicolored abdomen and the crisp, dark markings on the elytra. From Tachinus lecontei it is most easily identified by the fine microsculpture of the elytra which produces a strong metallic sheen (the former species completely lacks microsculpture).

This species is transcontinental in North America with a disjunct population in the Rocky Mountains of Colorado. It was previously known from the following states and provinces: Alberta, Colorado, Manitoba, Massachusetts, New Hampshire, New Jersey, New York, North Dakota, Pennsylvania, Québec, Saskatchewan, and Vermont. Herein we newly record it from Ontario (Map 11). The only habitat data in Campbell (1979) - "treading under Alnus", and the lakeside habitat of the Ontario specimen recorded here suggest an affinity for decaying organic matter near water, but further collecting is necessary to confirm this.
