Saharo-Sindian buthid scorpions; description of two new genera and species from Occidental Sahara and Afghanistan

Two new genera and species of Saharo-Sindian buthid scorpions are described on the basis of single specimens collected respectively in the deserts of Occidental Sahara and the North of Afghanistan. These new scorpion taxa represent further endemic relicts in the Saharo-Sindian faunas. Comments are also included on the evolution of the desert regions of North Africa and the Middle East, as well as the possible consequences of these events on the distribution of the extant scorpion fauna.
