The little-worn deciduous fourth premolar and first molar of a mandibular fragment of Homunculus sp are compared with the cast of a previously described deciduous lower fourth premolar of Homunculus grandis and with lower molariform teeth of Alouatta and Stirtonia. Lower molars of Alouatta can be derived from those like Homunculus, but because of the fragmentary nature of the fossils, it cannot be demonstrated that Alouatta evolved from Homunculus or is even closely related. Comparison of mandibles and upper and lower molariform teeth of Alouatta with those of Stirtonia indicate wide divergence from some distant, possibly basic platyrrhine stock.
将侏儒猴属一个下颌骨碎片上磨损较少的乳前磨牙和第一乳磨牙，与先前描述的大侏儒猴乳下第四前磨牙的模型以及蛛猴属和斯特蒂尼亚猴属的下臼齿状牙齿进行了比较。蛛猴属的下臼齿可能源自类似侏儒猴属的牙齿，但由于化石的破碎性质，无法证明蛛猴属是从侏儒猴属进化而来的，甚至无法证明它们有密切的关系。将蛛猴属的下颌骨以及上、下臼齿状牙齿与斯特蒂尼亚猴属的进行比较，结果表明它们与一些遥远的、可能是基本阔鼻猴类种群有很大差异。
