Male and female have a similar appearance. The topside looks similar to several other tropical butterflies, related and unrelated. In particular its topside is similar to the Sailer butterflies of the same region (which also have a tan underside but have no black spots on the third bar) and the female Orange-banded Shoemaker of the Americas (without the rust spots).
