Volume 6/2 of the Catalogue of Palaearctic Coleoptera focuses on the second part of the beetle superfamily Chrysomeloidea reported from the Palaearctic biogeographic region. For the genus and species-groups taxa all relevant names are given and all nomenclatural data are cross-checked and the distribution of species and subspecies is given per country or smaller region. A group of 14 experts have worked to collect data based on a critical review of published sources including a significant amount of new information. This volume is also a tool for specialists as well as amateurs, which warrants unambiguous communication.
