Material examined.

CANADA: ON: Huron Co., Auburn, hedgerow, pitfall, 11.v.2010, A. Brunke, 3 (DEBU), Benmiller, hedgerow, pitfall, 22.vi.2009, A. Brunke, 1 (DEBU).

Distribution.

Canada: ON; western Palaearctic ( Assing 2001). Adventive in Canada.

Comments.

Callicerus rigidicornis is recorded from North America as an adventive species for the first time based on Ontario specimens collected in agricultural hedgerows. Males of this species do not have their antennomere 10 conspicuously elongate as in Callicerus obscurus . Callicerus rigidicornis is separated from Callicerus obscurus by the more transverse pronotum (Fig. 65). In both its native range and in Canada, this species is collected from the same habitats as Callicerus obscurus though the true microhabitat may be subterranean ( Assing 2001).
