Diagnosis

Females are similar to Lasioglossum (Hemihalictus) taeniolellum (Vachal, 1903) but differ by the labrum without lateral projection on distal process (Murao et al. 2010: fig. 1m) and mesepisternum with shallow PP on upper area (Murao et al. 2010: fig. 1f). In contrast, in L. (H.) taeniolellum, the distal process of labrum has a horn-like lateral projection (Fig. 14D) and a mesepisternum with deep PP on the upper area.
