Description:This supplement comes not only to correct the inaccuracies and mistakes in the authors' monograph of 1997, but also to update the nomenclature, taxonomy and distribution of the Alticinae, or flea beetles, in the Palaearctic subregion. As a result, 83 names of flea beetles are eliminated, mostly as synonyms, while 113 species are added. So the total number of species or subspecies has increased from 1,358 to 1,388. The following three genera are added to the regional list: Aeschrocnemis, Cyrsylus and Heyrovskya.
