Psammotermes allocerus Silvestri, 1908 is a sand termite that lives in the deserts of Namibia and neighboring countries. They are thought to be responsible for the creation of fairy circles. Psammotermes is essentially a desert-dwelling termite, and seems to replace Anacanthotermes in drier areas. Well-adapted to very dry conditions, it may be found in areas where there is little evidence of other arthropods. The species even inhabits areas where there are no vegetation: in those cases, it is thought to survive on the wind blown accumulation of organic debris. It is also found in the dry regions of the southern African interior that are almost devoid of soil. Coaton & Sheasby (1973).
