Abstract: Two suids identified as Sus xiaozhu and S. peii associated with Gigantopithecus unearthed from Sanhe Cave are systematically described. Sanhe Cave is at least the 12th site yielding S. xiaozhu and at least the 9th site yielding S. peii, both finds recognized as the southernmost location in China so far. This evidence confirms the thriving period of both S. xiaozhu and S. peii in the Early Pleistocene and Guangxi as their favorable habitat. Although S. xiaozhu chronologically ranges from the early stage of the Early Pleistocene to the early stage of the Late Pleistocene and S. peii chronologically ranges from the early stage of the Early Pleistocene to the early stage of the Middle Pleistocene, the co-occurrence of S. xiaozhu and S. peii happens always in the Lower Pleistocene. Sanhe Cave is the 6th Early Pleistocene site yielding both types of suids, which are often found with Gigantopithecus; Sanhe Cave is the 5th site with such an association. The presence of these two suids indicates that the Early Pleistocene environment around the cave was forested with scrub and swamps nearby.
