Abstract: Based on newly discovered materials and old collections we review one important bovid group referred to ?Protoryx. Detailed comparison with other forms from western Eurasia suggests that all the Protoryx forms found in China can be separated into two groups, which are both different from other forms described as Late Miocene or earlier species of Protoryx. Hence, we propose two new genera, Huabeitragus gen. nov., and Macrotragus gen. nov. in this paper. Huabeitragus has a strongly bent cranial braincase, which makes the cranial axis interact with the facial axis at a right angle. The turning point occurs at the fontal anterior to the horn bases. The supraorbital foramina are small and widely set apart. There is a raised ridge along the frontal suture between the horn cores. The braincase is short and narrow. The occipital surface is low and wide, facing posteriorly. The basioccipital is rectangular with a flat or slightly concave surface, without a developed longitudinal groove or ridge, and the anterior and posterior tuberosities less developed. The horn cores have anterior keels and subtriangular shaped cross sections. The horn cores are very divergent upwards in anterior view. Macrotrgus has a large skull and horn cores. The facial, orbital, and cranial parts are wide. The upper orbital rims do not protrude laterally. The supraorbital foramina are small and widely set apart. The braincase is shorter and wide, with parallel lateral sides. The occipital surface is flat, facing posteriorly. The horn cores are laterally compressed and curved. Compared with the molar row the premolar row is shortened. Huabeitragus differs from Macrotragus in its smaller size, strongly bent braincase with the turning point more anterior, narrower braincase, lower and wider occipital surface, rectangular basioccipital without longitudinal groove and weak ridge, smaller foramina ovalia, and less robust, more divergent horn cores, with subtriangular cross section at the base and having keels. Characters shared by Huabeitragus and Macrotragus, are comparable with those of Caprinae. Therefore, we consider these two new genera as members of Caprinae.
