Comments: The first mention of C. maracajuensis for Paraguay was given by Pardiñas and Teta (2005) who mentioned specimen CE 2589 without giving locality data. This specimen was collected at Luque in the Department of Central (Pablo Teta, com. pers.). Our records expand to the northeast and southeast the known distribution of this species in Paraguay. A female collected in March (2001) gave birth to three young (measurements of one young were TBL=89, TL=36, HF=12, EL=5, W= 6g). Other females collected at the same time had open or closed vagina. Specimens in San Pedro were collected with traps set on the ground in riparian forest and in nearby grasslands together with Akodon montensis , Calomys callosus, Didelphis albiventris Lund, and Oligoryzomys nigripes .
