Augochlora is a genus of mainly tropical bees with few representatives in both North and South American temperate areas. We clarify in this contribution the systematics of the species with southernmost distribution. Only five species occur in a vast region including central Argentina, Uruguay and southern Rio Grande do Sul in Brazil, between 29º and 39º south latitude: A. iphigenia Holmberg, A. amphitrite (Schrottky), A. nausicaa (Schrottky), A. phoemonoe (Schrottky) and A daphnis Smith. The first four species are common elements in the bee asemblages of the area. The fifth species, described from Montevideo , Uruguay , is known only from the type specimen. Redescriptions, illustrations, distributional data, and a key to the species are presented. A lectotype is designated for Augochlora iphigenia Holmberg, 1886. Oxystoglossa semiramis Schrottky, 1911, and Halictus brochidens Vachal, 1911, are new synonyms of A. iphigenia Holmberg. Odontochlora thebe Schrottky, 1909, and Odontochlora cephalica Moure, 1941, are new synonyms of Odontochlora amphitrite Schrottky, 1909.
