Volume 5 of the Catalogue of Palaearctic Coleoptera focuses on one of the megadiverse groups of the animal kingdom, the beetle superfamily Tenebrionoidea reported from the Palaearctic biogeographic region. For the genus and species-groups taxa all available names are given and all data relevant to nomenclature are cross-checked and the distribution of species and subspecies is given per country or smaller region. A group of 25 experts have worked to collect data based on a critical review of published sources including a significant amount of new information. This volume also provides a fix to the nomenclature, which warrants unambiguous communication.
