Diagnosis. Female L. zephyrum can be recognised by the following diagnostic combination: size relatively large (5.31–7.08 mm); head wide (length/width ratio = 0.94–0.95); lower paraocular area with dense tomentum obscuring surface; gena wider than eye; hypostomal carina parallel; mesoscutum polished, punctures fine, moderately sparse between parapsidal lines (i= 1–2 d); mesepisternal punctures fine, sometimes obscure; metapostnotal rugae reaching approximately halfway to posterior margin; and metasomal terga polished with faint metallic reflections.

Male L. zephyrum are similar to females but can be further distinguished by the following combination: clypeus sometimes brownish yellow apically; denser tomentum on paraocular area; flagellomeres long (length/width ratio = 1.75–1.86), bright yellow ventrally; gena narrower than eye; mesepisternal punctures distinct; tarsi, apices and bases of tibiae pale brownish yellow; metapostnotal rugae longer, posterior margin smoothly rounded onto posterior propodeal surface; and metasomal terga colour variable from brown with greenish reflections to orange-red.

Range. Quebec west to Alberta, Oregon, south to Florida, Texas. USA: AL, CO, CT, DE, FL, GA, IA, IL, IN, KY, MA, MD, ME, MI, MO, MT, NC, NE, NY, OR, PA, TN, TX, VT, WI, WV. CANADA: AB, MB, ON, PQ.

DNA Barcode. Available. Multiple sequences.

Comments. Common.
