Genus Augochloropsis Cockerell

Diagnosis.

Both sexes of Augochloropsis are diagnosed by the unique shape of the tegula, which has the inner posterior margin hooked (Fig. 1A ). Females have the inner hind tibial spur with multiple straight teeth compared to broad teeth in Agapostemon or untoothed spurs in Augochlorella and Augochlora . Augochloropsis males have a uniquely-shaped S4 (see Fig. 20C, H, M ), with a median point and lateral arms, though the sternum is typically hidden. Though typically strongly metallic green, many individuals are metallic bluish or even purplish.
