Gabrius amulius Smetana, 1995

Materials.

CANADA: ON: Simcoe Co. Midhurst, forest nr. Neretva St., under bark of large beech trunk, 4-IX-2009, A. Brunke and K. Brunke (1).

Diagnosis.

Gabrius amulius may be recognized by the combination of: large size (at least 5.0mm long from clypeus to abdominal apex); eyes large, with temple that is distinctly less than twice as long as the eye; forebody without a greenish metallic lustre; elytra with sparsely distributed punctures that are separated by two to three times their diameter; area between basal lines on tergites two and three punctate

This apparently rare species was known from only five specimens at the time of its description ( Smetana 1995) from localities in New York and Ohio. It was collected in Missouri by Watrous (2008) in a flight intercept trap. Herein we newly report it from Canada (Ontario) (Map 24). All known specimens with microhabitat data were collected in deciduous forests in litter, or in the proximity of decaying wood. Gabrius amulius is almost certainly an uncommon specialist of deciduous or mixed forests.
