This work focuses on the genus Proechimys, a group of spiny rats found predominantly in South America, exploring the complexities of their taxonomy and speciation. It delves into the differences between species and subspecies within Brazil, offering insights into their physical characteristics, evolutionary history, and ecological adaptations. The opening of the work introduces the genus Proechimys, detailing their habitat preferences in South America and highlighting the physical attributes that distinguish them from other rodent families. It establishes the groundwork for a comprehensive examination of the various species, aiming to clarify the extensive taxonomic confusion that has persisted over the last century regarding these animals. The early sections also outline the methods and terminology that will be utilized in the analysis, emphasizing a systematic approach to studying the variations in pelage, skull morphology, and dental structure among the species.
