Geographic distribution of endemic dung beetles (Coleoptera, Scarabaeoidea) in the Western Palaearctic region

The distribution of endemic dung beetle species has been analysed in the West Palaearctic region (547 spp.) These species are concentrated in the Mediterranean Basin or in the neighbouring regions, with two main centres of endemism located on opposite sides of this Basin The centres of endemism and the degree of endemicity were very different according to the three main dung beetle families The possible explanation of these patterns has been examined
