In this paper a new chilothere species, Acerorhinus hezhengensis represented by associated skull andlower jaw from Late Miocene deposits of Hezheng, Gansu, is described. The Chinese “Diceratherium”problem is reviewed and analysed. Systematically, the Chinese “Diccratherium” has scarcely any direct rela-tion with the true Diceratherium of North America. Heissig’s referral of the Chinese “Diceratherium” toChilotherium as a subgenus is here disputed. A series of distinctive characters warrant the Chinese “Di-ceratherium” a generic rank, for which Acerorhinus created by Kretzoi in 1942 is adopted. Acerorhinusshares common apomorphic features exclusively with Chilotherium. They may represent a separate tribein the subfamily Acerotheriinae: Chilotherini.
