Abstract
A new Oligoryzomys species from Central and Northeastern regions of Br azil, Oligoryzomys stramineus sp. n., is described based on morphologi c, biogeographic, and karyotypic analyses. A comparison with other Oli goryzomys species resulted in the distinction of two species groups: o ne comprising large-sized species with a white ventral surface (O. cha coensis, O. nigripes, O. delticola, and O. stramineus sp. n.) and anot her, comprising small-sized species with a yellow ventral surface (O. fornesi, O. microtis, and O. flavescens).
