( Figures 42 A–D; 43A–D; 50E)

Augochlora seitzi Cockerell, 1929: 299 , holotype, ♀ (AMNH) from Brazil, São Paulo, Santos. Examined through photo-graphs.

Diagnosis. Augochlora seitzi has the apex of T1 inflexed on both sexes ( Fig. 2B ). Females have a spiniform projection on S1 ( Fig. 1J, L ) and males have the mesoscutum disc densely punctate (I <PD) and the F1 lighter than F2. This species can be easily confounded with A. phoemonoe , but differs in the straight lower margin of female mid trochanter (widely rounded in A. phoemonoe ), and T3 coarsely punctate near base, loosely imbricate on disc (with average size punctures and disc smooth in A. phoemonoe ) and T2 smooth near marginal area on males. Besides this, A. seitzi has a tendency to occur in the coastal Atlantic forest, while A. phoemonoe has a wider distribution comprising southern and westernmost areas.
