Eurema sp.
That's for once a very tricky one!! It is an Eurema sp., I saw a perfect match (Eurema arbela boisduvalia) but this guy is not found in Brazil. Xantochlora looks also quite good but is neither found in Brazil. I have to go deeper in the literature. Unfortunately there are even conflicting data from d'Abrera and Lamas.
