The first known upper dentitions--an adult and subadult--of the cercamoniine adapiform Aframonius dieides are described. Comparisons show that A. dieides has an upper molar morphology resembling that of other cercamoniine adapids but the species lacks some of their typical specializations. The new dental material confirms that Aframonius stands closer to Mahgarita from west Texas and Cercamonius from Europe than it does to Schizarodon and Omanodon from Oman-all of which have been ranked as cercamoniines. Affinities of the latter two genera probably lie with the Anchomomys group. The presence of a cercamoniine adapid in the Eocene of Egypt supports the view that early African anthropoideans evolved not in isolation, but concomitantly with a contemporary Eocene prosimian radiation.
描述了已知的首例非洲阿法猴（Aframonius dieides）的上牙列，包括一具成年个体和一具亚成年个体。比较结果显示，阿法猴的上臼齿形态与其他 cercamoniine 类灵长目动物相似，但该物种缺乏它们的一些典型特化特征。新的牙齿材料证实，与阿曼的裂齿猴（Schizarodon）和阿曼猴（Omanodon）相比，阿法猴与来自得克萨斯州西部的玛格丽塔猴（Mahgarita）以及来自欧洲的 cercamonius 关系更近，后两者都被归类为 cercamoniine 类。后两个属可能与安氏猴（Anchomomys）类群有亲缘关系。在埃及始新世发现 cercamoniine 类灵长目动物，支持了早期非洲类人猿并非孤立进化，而是与同时期的始新世原猴辐射共同进化的观点。
