Cebuella，Callithrix，Leontopithecus和Saguinus共有5个区别特征。所有这些特征最好被解释为在扁鼻兽中衍生的性格状态，这些动物是谱系侏儒。这些衍生的性状可能形成一个单一的复合体，作为矮化的结果而进化。在哺乳动物中，齿系的两种变化与侏儒有关。这4个广鼻属可能或可能不形成一个单系群。卡利米科可能是一种早期的侏儒宽鼻鱼。哺乳动物侏儒的原因进行了讨论。
Cebuella, Callithrix, Leontopithecus and Saguinus share 5 distinguishing features. All of these features are best interpreted as derived character states within Platyrrhini, and these animals are phyletic dwarfs. These derived traits may form a single complex that evolved as a result of dwarfing. Two changes in the dentition are correlated with dwarfing in mammals. These 4 platyrrhine genera may or may not form a monophyletic group. Callimico may be an incipient dwarf platyrrhine. Causes of dwarfing in mammals are discussed.
