Lasioglossum (Evylaeus) yamanei Murao, Ebmer & Tadauchi, 2006: 46–49 (holotype: ELKU, ♀; type locality: Ibaraki Pref., Japan).
Evylaeus (Glauchalictus) yamanei – Pesenko 2007a: 26.
Diagnosis
This species is separated from the other members of the atroglaucum subgroup by a combination of the following characters: disc of male S4 with sparse hairs (Fig. 4C); male S5 deeply ∩-shaped apically (Figs 4C, 5H); and gonostylus of male genitalia large, obliquely truncated in lateral view (Murao et al. 2006, Fig. 11B). It may be closely related to L. taiwanense Murao sp. nov. from Taiwan in sharing the male S5 without a groove, the apical margin of male S5 incurved, and the ventral retrorse lobe of male genitalia short.
