Lasioglossum (Evylaeus) metis Ebmer 2002: 885, Figs 228–230 (♀) [Holotype: Biologiezentrum / Oberösterreiches Landesmuseum, Linz, Austria, ♀, type locality = Qinling-Gebirge, Shaanxi Prov., China]; Murao & Tadauchi 2008b: 100, Figs 3–4, 5B (♀ ♂).

Diagnosis. This species is similar to L. transpositum from eastern Asia. It is separated from L. transpositum by the following character states: female supraclypeus with sparser PP (IS = 3 d in maximum); female labrum with small lateral projection on distal process (Murao & Tadauchi 2008b, Fig. 3 G); female postgena with distinct lineolation; mesepisternum nearly smooth on upper area in both sexes; and male metasomal sterna with uniform and sparse hairs. In contrast, in L. transpositum, female supraclypeus with denser PP (IS = 1.5 d in maximum), female labrum without lateral projection on distal process (Murao & Tadauchi 2008b, Fig. 1 H), female postgena nearly smooth, mesepisternum punctate on upper area in both sexes, and male S2–S5 lateroapically with thin hair tufts (Murao & Tadauchi 2008b, Fig. 2 F).
