This subgenus is characterized in having the following features: 1) lower margin of clypeus reflected forward (Fig. 5); 2) female mandible with two apical teeth (Fig. 6); 3) basal elevation of male labrum high swelled, with longitudinal furrow (Fig. 8); 4) male S 2 gently swelled on apical part (Fig. 15); and 5) male S 6 expanded apically as in Fig. 20 (Michener 2007; Pesenko 2007 a). In this study, we noticed an additional apparently unique character, namely the female labrum lacking basal elevation (Fig. 7). The comparative morphological study of labrum has not been performed yet in the genus Lasioglossum, but this character state may be an autoapomorphy. Figures 1 - 6.
