Spotting

Sounds good. I have many pictures of this one and can look through but probably nothing to the detail needed to separate. Will be back on site in a couple of months and can look harder then.

Junonia sp., it is either Junonia genoveva or Junonia evarete. From both are reports from Brazil and both looks "identical". Many of them are wrongly IDed and there are many scientific papers about these ones, however, all with conflicting results. The fact, that the underside of the antennae/tips might be used for separation is not accepted by all authors. Personally I can't separate them and if you look at both my links, you might know why...

Genoveva:

To be on the safe side I personally would go with Junonia sp. with mentioning that it could either be Junonia evarete or Junonia genoveva.
