Augochlora francisca Schrottky, 1902: 391 . Lectotype, ♀ (MZUSP, accession number 17,637) from Brazil, São Paulo, Jundiaí and Campinas is presently designated to stabilize species taxonomy. Examined.

Odontochlora thetis Schrottky, 1909: 143 . Syntypes, ♀ (whereabouts unknown) from Paraguay, Alto Paraná, Puerto Bertoni .

Diagnosis. Augochlora francisca females have a long and slender projection on S1 and the rugose preepisternum. The females differ from the similar Augochlora scabrata sp. nov. by the body coloration, the T1 dorsal surface is black with purplish iridescences and by the mid trochanter ventral margin swollen near base. Males can be recognized from other Augochlora by the combination of the clypeal border hidden below clypeus apex, T1 anterior surface without abundant tiny setae among long setae and hypoempimeral area contiguously to crowded punctate. Frequently the males also present purplish iridescences on T1 dorsal surface.

Comments. We examined one female syntype of Augochlora francisca deposited in MZUSP and it belongs to a common species found in southeastern Brazil, the examined syntypes is designated as lectotype to stabilize the taxonomy of the species. The original description is also useful for species recognition. The synonymy with Odontochlora thetis was made by Moure (1940).
