The classical zoogeographical subdivision of the land fauna, done by Sclater and Wallace in the nineteenth century, is still “official” in our time. This subdivision has been based on vertebrates, mostly mammals and birds. The ocean of tiny creatures (insects, arachnids, etc.) has been (and still is) largely neglected. Some attempts have been done to restructure the old scheme (Lopatin, Krizhanovskiy, Morrone, etc.), but nothing has been done for the total of Arachnida – old groups of non-flying invertebrates, quite important for zoogeography and already relatively well known.
