Taxonomic history
Originally described as Calantica polita by Walsingham in 1881, this was later transferred to the Eucalantica. For over a century, E. polita remained the only known species in the genus from the Nearctic region, giving the impression that Eucalantica was a or species-poor genus in North America. The 2011 revision by Sohn and Nishida revealed substantially greater diversity in Central America.
