Holotype. ♀ USA, Colorado, Boulder, 13.iv.1913, (M.D. Ellis); [UCMC]. Examined. Taxonomy. Michener, 1951: Lasioglossum (Chloralictus) zophops, p. 1118 (catalogue); Hurd. 1979: Dialictus zophops, p. 1973 (catalogue); Moure & Hurd, 1987: Dialictus zophops, p. 142 (catalogue). Diagnosis. Females of L. zophops can be recognised by the diagnostic combination of a large size (6.1– 7.1 mm), wide head (length/width ratio = 0.92–0.94), imbricate-tessellate mesoscutum with sparse punctures on centre of disc, rugulose mesepisternum with obscure punctures on ventral portion, metapostnotum distinctly truncate, T1 acarinarial fan complete dorsally and brown metasomal terga with distinct punctures on the apical impressed areas. They are most similar to L. laevissimum and L. versatum. Female L. laevissimum have the apical halves of the metasomal terga impunctate. Female L. versatum have the T1 acarinarial fan incomplete dorsally. Males of L. zophops are similar to females and may be further distinguished by the moderately wide head (length/width ratio = 0.95–0.99), distinct mesepisternal punctures, relatively polished mesoscutum, obtuse dorsolateral angles of the pronotum and scattered punctures on the apical impressed margins of the metasomal terga. They are most similar to L. obscurum and the Eastern USA species L. wheeleri. Male L. obscurum have elongate heads (length/width ratio = 1.02–1.05) and no punctures on the apical impressed areas of the metasomal terga. Male L. wheeleri have acute dorsolateral angles of the pronotum and no punctures on the apical impressed areas of the metasomal terga. Redescription. FEMALE.
