Explanation of Names
Homaemus aeneifrons (Say 1824)
aeneifrons 'bronze forehead'

■ SECTION NEEDS REVISION ■ lack of yellowish submarginal stripe on head is diagnostic for eastern specimens. The subspecies restricted to the west, H. aenifrons consors typically has the yellow stripe. H. bijugis is smaller (5.7‒8 mm), has yellowish submarginal stripe on head, and in Canada is restricted to the west (MB‒BC)(see species page at U. of Alberta). Some workers have synonymized H. aenifrons consors and H. bijugis, further confusing matters.; H. parvulus has yellow pubescence on head (lacking in H. aenifrons) and in Canada is restricted to BC(2)
