Abstract
Extensive field work conducted in Paraguay since 1995 allowed us to present the first records for this country of the family Sciuridae (Sciurus urucumus), the genus Bibimys (B. chacoensis), and the species Akodon paranaensis, in addition to the first formal mention of Oxymycterus misionalis, and noteworthy records of Cerradomys maracajuensis, Pseudoryzomys simplex, and Sphiggurus spinosus. These records demonstrate that the mammal fauna of the Paraguayan Oriental Region is more similar in species richness and composition to that of adjacent regions of Argentina and Brazil than previously realized.References
