The present updated and revised Catalogue is a collective international work by 12 authors. 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.

An expanded and updated edition of the out-of-print 2003 supplementum of Zoology in the Middle East, this concise guide to Darkling Beetles of the Sinai Peninsula has been sought after by researchers in taxonomy, faunistics and biogeography. The new book includes two additional subfamilies of tenebrionid beetles (4-5 species), identification keys and more than 90 colour photographs and species distribution maps. Zoogeographically speaking, the Sinai Peninsula is a crossroad and, at the same time, a center of speciation. Despite its generally arid character, the region harbours a wide range of habitats, from sea level to over 2,500 m above. About 10 percent of the Sinai darkling beetles are endemic to the area. The inclusion of species photographs and identification keys makes this book an invaluable reference field guide, for both specialists and non-specialists, who will thus be able to discover the taxonomic and phylogenetic diversity of darkling beetles in the Sinai Peninsula.

A comprehensive work covering the about 100,000 species of Coleoptera known to occur in the Palaearctic Region. The complete work is planned for 8 volumes that will be published in intervals of about 18 months. The information provided for each species will be the following: • Primary taxonomic information of all available names in the genus and species levels published by the end of 1999. • The taxonomic information below subfamily will be organized alphabetically. • The type species of genera and subgenera, incl. synonyms, are given. • The area covered also includes the Arabian Peninsula, Himalayas and China. • The distributional data of species and subspecies is given per country. • Detailed distributional information for strict endemics is given. • Introduced species are indicated. The catalogue is a collective work of about one hundred coleopterists from Europe, Japan, America and Australia.
