Diagnosis

This species is similar to Lasioglossum angaricum (Cockerell, 1937) and L. viridellum (Cockerell, 1931) from eastern Asia in the leucopus group. It is separated from L. angaricum by the female T1 usually being without lineolation (sometimes T1 basally lineolate, but weaker than in L. angaricum ) and the male sterna with sparse uniform hairs. In contrast, in L. angaricum the female T1 has distinct lineolation and the male S3–S5 is medially bare, laterally with tufts of long dense erect hairs ( Pesenko 2007b). For the differences between females of this species and L. viridellum , see Key.
