A partial face and mandible from the early Miocene site of Napak IX in Uganda are described here as a new genus and species of catarrhine primate, Lomorupithecus harrisoni gen. et sp. nov. The face is among the most complete specimens known for a Miocene small-bodied catarrhine. Several aspects of its anatomy indicate that the new species is a stem catarrhine, and as such, it may provide valuable information pertaining to the primitive catarrhine cranial morphotype. Lomorupithecus is most similar in its facial anatomy to members of the Pliopithecoidea, and these similarities could be interpreted in three ways. They could be symplesiomorphies, which would support the traditional view of the primitive catarrhine cranial morphotype; they could be synapomorphies reflecting a phylogenetic position of Lomorupithecus within Pliopithecoidea; or they could represent convergence. Phylogenetic analysis of Lomorupithecus along with 35 other primates indicates that it is a pliopithecoid. As such, it would be the oldest and only Afro-Arabian member of this otherwise Eurasian clade.
本文描述了来自乌干达纳帕克IX中新世早期遗址的部分面部和下颌骨，它们属于一种新的狭鼻猴灵长类动物，即哈氏洛莫鲁猿（Lomorupithecus harrisoni），新属新种。该面部是已知的中新世小型狭鼻猴中最完整的标本之一。其解剖结构的几个方面表明，新物种是一种狭鼻猴干群，因此，它可能提供有关原始狭鼻猴颅骨形态型的有价值信息。洛莫鲁猿的面部解剖结构与上新猿超科成员最为相似，这些相似性可以有三种解释。它们可能是共祖特征，这将支持原始狭鼻猴颅骨形态型的传统观点；它们可能是共衍征，反映了洛莫鲁猿在中新猿超科中的系统发育位置；或者它们可能代表趋同现象。对洛莫鲁猿以及其他35种灵长类动物的系统发育分析表明，它是一种上新猿超科动物。因此，它将是这个原本分布于欧亚大陆的类群中最古老且唯一的非洲 - 阿拉伯成员。
