This omission has a cost: the lack of an introduction to the four main lineages within caviomorphs, recognized as superfamilies (Erethizontoidea, Cavioidea, Chichilloidea, and Octodontoidea).
Within Caviomorpha, the 4 traditional superfamilies were recovered with ~32 Ma stem divergences as Cavioidea + Erethizontoidea and Chinchilloidea + Octodontoidea.
Dentro de Caviomorpha se incluye a los roedores histricognatos e histricomorfos endemicos de America Neotropical, los cuales se clasifican en cuatro superfamilias: Octodontoidea, Cavioidea, Chinchilloidea y Erethizontoidea. De ellas, los Octodontoidea representan la superfamilia de mas alta riqueza especifica y diversidad adaptativa y su monofilia esta sustentada por la microestructura del esmalte de los incisivos.
