As recommended by Adam, I decided to share this story of our new pierid butterfly here, in addition to a link to the paper that came out few weeks ago (open access in Zootaxa).
For those of us who spend our lives in contemplation of Neotropical butterflies, discovery of such a highly distinctive new species reminds us why, and for those who have yet to explore the diversity down there, discovery like this might explain how rewarding it can be to study them.
