Abstract: Compared with the Sivapithecus specimens from Pakistan and Turkey, the Lufeng Sivapithecus has the following traits:
1. Enormous interorbital breadth,
2. Broad and short face.
3. Broad, short and shallow hard palate.
4. Ovoid orbits with horizontal longest dimensions and with somewhat angled outer corners,
5. Dental arch diverges posteriorly,
6. Different tooth morphology, molars with higher cusps and more wrinkles on the occlusal surfaces.
Thus, it is suggested to bestow the Lufeng specimens a new genus name, Lufengpithecus lufengensis.

Key words: Sivapithecus; Ramapithecus; Lufengpithecus
