A new representative of the pachycephalosaur family Homalocephalidae Dong is described, which comes from the Upper Cretaceous deposits of the Gobi-Desert, Mongolian People's Republic. It is more primitive and probably stratigraphically older than Homalocephale calathocercos known from the Upper Cretaceous Nemegt Formation of the Gobi Desert. The diagnosis of H. calathocercos is revised.

Key words: dinosaurs, Ornithischia, Pachycephalosauria, Cretaceous, Mongolia.
