Abstract: A new species of large bovid Shaanxispira, S. baheensis is briefly described. The materials were found from the middle part of the Bahe Formation, Lantian County, China. S. baheensis is characterized by having straight horn cores with a clockwise twisted keel on the right, positioned behind the orbit. The braincase is rather short in respect to the width, and the cranial axis is at about 90°with the facial axis. The occipital surface is wide and flat with a wide mastoid exposure. No basal pillars on the labial side of lower and on the lingual side of upper molars. The phylogenetic relationships of the Shaanxispira with some other large bovids are also tentatively discussed. There possibly existed a group of large bovid of tribal or subfamilial level that died out during the late Miocene, which includes the Urmiatherium, Plesiaddax, Hezhengia, Shaanxispira, and possibly Sinotragus.
