Comparisons of a moderately worn pm4 in its jaw, and an isolated dpm4 of the Oligocene-Miocene Homunculus (the second tooth originally described as that of a marsupial), indicate cebid identity with affinities nearest Alouatta. Diagnoses of dpm4, pm4 and m1 of all known platyrrhines and comparisons with teeth of strepsirhines and tarsioids reveal that platyrrhines cannot be derived from any known non-platyrrine stock. Speculations on platyrrhine ancestry are reviewed.
对下颌中磨损程度适中的pm4与渐新世 - 中新世小精灵猴（最初被描述为有袋类动物牙齿的第二颗牙齿）的孤立dpm4进行比较，表明阔鼻猴类与亲缘关系最接近蛛猴属的动物具有相同特征。对所有已知阔鼻猴类的dpm4、pm4和m1进行诊断，并与狐猴型下目和眼镜猴类的牙齿进行比较，结果显示阔鼻猴类并非起源于任何已知的非阔鼻猴类种群。本文对阔鼻猴类祖先的推测进行了综述。
