Pia Öberg from Sweden took this cicada photo back in 2004 at Hotel do Ypê in Itatiaia NP in Brazil. Thanks to Roy Troutman and cicada expert Allen Sanborn we were able to ID this pretty cicada as a Carineta diardi (Guérin-Méneville, 1829). In addition to Brazil, C. diardi is also found in Argentina.
Species: Carineta diardi (Guérin-Méneville, 1829)
