The aim of Catalogue of Palaearctic Coleoptera is to provide a tool that addresses the most urgent needs:
1) a complete list of available names of taxa occurring in the Palaearctic Region with authors and publications dates,
2) a list of references to primary publications,
3) distributions of the species and subspecies.
Thus, the Catalogue is expected to respond to questions related to biodiversity, and to increase the badly needed nomenclatural stability.
The present updated and revised Catalogue is a collective international work by 12 authors from Austria, Belgium, China, Korea, Japan and Russia. It includes about 6453 species names of 913 genera. The general structure and the taxonomic, distributional and bibliographical information of the first edition of the Catalogue are followed with minor changes.
