Lasioglossum (Evylaeus) sphecodicolor Sakagami & Tadauchi, 1995: 191 , figs 52, 55, 57, 59, 61–65, 67–68 (♀ ♂) (holotype: Systematic Entomology, Faculty of Agriculture, Hokkaido University, Japan, ♀, type locality =Takizawa Experim. Forest, Iwate Pref., N. Honshu, Japan).

Diagnosis

Females are similar to L. (H.) eidmanni (Blüthgen, 1930) . According to Sakagami & Tadauchi (1995), this species is only separated from L. (H.) eidmanni by the metasomal terga without distinct apical fimbriae. In contrast, in L. (H.) eidmanni , the metasomal terga have more or less dense and welldeveloped apical fimbriae.
