Voltinia sp.
It seems that this butterfly had a troubled life.
It is not a moth, but a Metalmark/Riodinidae. I am pretty sure it is Voltinia sp., Voltinia umbra looks perfect, but I didn't find yet a corresponding and reliable source for finding it is Brazil. There is a Voltinia phryxe in Brazil which looks very similar, but without the tiny white spots on the forewing. But they are old specimens, so this spot is just missing/not visible anymore.
