Halictus transpositus Cockerell 1925: 8 [Holotype: U.S. National Museum of Natural History, Smithsonian Institution, Washington, D.C., USA; ♀, type locality = Kongaus (now, Anisimovka, Primorsk Terr.), Russia, examined]. Halictus tutihensis Cockerell 1925: 8 [Holotype: U.S. National Museum of Natural History, Smithsonian Institution, Washington, D.C., USA; ♀, type locality = Tutihe (Primorsk Terr.), Russia].
Evylaeus (Microhalictus) transpositus: Pesenko 2007b: 84 (in key), 93 (in key), 109, Figs 83–85 (♂). Lasioglossum (Evylaeus) transpositum: Ebmer 1996: 286; Ebmer 2002: 879; Murao & Tadauchi 2008b: 96, Figs 1–2, 5A, (♀ ♂).
Diagnosis. This species is similar to L. metis from eastern Asia. It is separated from L. metis by the following character states: 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). In contrast, L. metis has 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.
