The genus contains only one species, Eupales ulema, which is found in Southeast Europe, mostly in Hungary, the Balkan Peninsula, and Turkey.
[2] The genus was originally known as Pales, named in 1836 by the French entomologist Louis Alexandre Auguste Chevrolat in Dejean's Catalogue des Coléoptères, but this name was preoccupied by the fly genus Pales Robineau-Desvoidy, 1830.
Floricola is an older available name for the genus, created by Gistel in 1848; however, almost all authors have used Eupales in the last 125 years.
In the sixth volume of the Catalogue of Palaearctic Coleoptera and in Bouchard et al. (2011), the genus is placed as incertae sedis within Eumolpinae instead.
[3] An application to the International Commission on Zoological Nomenclature was sent in 2009 to conserve both the names Eupales and Eupalini,[4] but the case was never published.
