| 摘要 | A unique juvenile skull bearing both milk premolars and unerupted but fully developed permanent premolars and molars (observed using X-ray microcomputed tomography), and some isolated upper cheek teeth, all from the Late Miocene hominoid fauna of the Yuanmou Basin (Yunnan, China), closely resemble craniodental material of Acerorhinus yuanmouensis Zong, 1998 from the same locality, and are referred to this species. A phylogenetic analysis based on 214 craniodental morphological characters scored for 31 terminal taxa reveals that A. yuanmouensis should be assigned to the genus Acerorhinus indeed. The newly discovered specimens improve our understanding of this species, especially with respect to the morphology of the milk premolars and premolars. Two intraspecific variations in the upper premolars are noted: a lingual bridge may be present or absent, and the lingual cingulum continuous or reduced. The analysis also indicates that: the phylogenetic status of Acerorhinus lufengensis Deng and Qi, 2009 should be reconsidered; "Aceratherium" huadeensis Qiu, 1979 does neither belong to Aceratherium nor Acerorhinus, and its phylogenetic status remains debatable.
