Evylaeus (Smeathhalictus) ellipticeps: Pesenko 2007a: 28 ; Pesenko 2007b: 85 (in key), 97 (in key), 117, Figs 124–127 (♂). Lasioglossum (Dialictus) ellipticeps: Murao et al. 2015a: 37 , 44–45 (in key), Figs 20–21, 26B (♀ ♂).

Diagnosis. According to Pesenko (2007b), this species is similar to L. briseis Ebmer and L. eomontanus Ebmer from eastern Asia. It is separated from these species by the following character states: female supraclypeus and clypeus dimly shiny, with denser PP (IS = <1 d); female mesoscutum with denser PP (IS = 0.3–1 d); male legs black; inner hind tibial spur of female with three and very long teeth; and ventral retrorse lobe of male genitalia tongue-like, rounded apically ( Pesenko 2007b, Fig. 126; Murao et al. 2015a, Fig. 21D). In contrast, in L. briseis and L. eomontanus , the female supraclypeus and clypeus more shiny, with sparser PP (IS => 1 d), the female mesoscutum with sparser PP (IS = 0.5–1.5 d), the male tarsi yellow, the inner hind tibial spur of female with five and relatively short teeth, and the ventral retrorse lobe of male genitalia pointed apically ( Pesenko 2007b, Figs 119, 122).

Distribution. North Korea, South Korea, Mongolia, Russian Far East.

Flight period in South Korea. Female: May to August. Male: July.

Flower records in South Korea. The floral records are reported as 10 species in six families by Murao et al. (2015a).
