Tragulids were reported from Arrisdrift by Corvinus and Hendey (1978) and Hendey (1978) on the basis of a few mandible fragments with partial dentitions. The Namibia Palaeontology Expedition has excavated many more remains of the same species, a lot of which are more complete. This paper is designed to complete the description of the Arrisdrift tragulid, and to compare it with material from other parts of Africa and Europe. It is a medium sized tragulid, being smaller than Dorcatherium chappuisi (Arambourg, 1933), larger than Dorcatherium songhorensis (Whitworth, 1958) and appreciably larger than Dorcatherium parvum (Whitworth, 1958) and Dorcatherium moruorotensis (Pickford, 2001).
