Ecology and Evolution, Volume 8, Issue 8, Page 3965-3982, April 2018., 2018 We tested and discussed different scenarios of diversification involving the Andes on three subtribes belonging to the Neotropical Ithomiini butterflies. To do so, we generated the first phylogeny of the most diverse subtribe of Ithomiini butterflies, the Dircennina (101 species). In the three subtribes, Central Andean lineages are old and diversifying
