Help to identify Brazilian butterfly

[marcial]

Hello!

I'm new here in the forum, and I hope I'm posting this thread on the right place. Can you please tell me what butterfly is this on the picture? It's some species very fond of my red Cosmos sulphureus flowers. I live in São Paulo, Brazil, if that helps.

The genus is Junonia - species is probably genoveva, but the latter and evarete have been badly confused and a revision is needed. If it's genoveva, the subspecies may be hilaris (its type locality is in Paraguay), but I'm not a specialist in the group and someone else may have better information.
