Abstract: New materials of Hippopotamodon ultimus associated withGigantopithecus have been collected in the systematic excavations carried out at Chongzuo since 2004. The taxonomic position of the former “Dicoryphochoerus” ultimus from Guangxi, Guizhou and Chongqing has been revised from Dicoryphochoerus to Hippopotamodon based on the study on both new and old materials, and H. ultimus is a valid species of Hippopotamodon. It is a suid larger than all known Sus with elongated snout, developed diastema between the P1 and the P2, short and narrow third lobe of the M3, verrucosustype lower canine, the main cusp of the p4 cleft at the tip into twin summits, double cusped third lobe of the m3. H. ultimus ranges only in South China. Its chronological distribution is limited from the early to the middle stages of the Early Pleistocene. It is an ultimate representative of Hippopotamodon.
