Thrichomys apereoides inhabits xeric and rocky environments in caatinga and cerrado domains in Brazil and chaco in Paraguay (Mares and Ojeda, 1982; Mares et al., 1985; Moojen, 1952; Streilein, 1982a). In Exu, Brazil, T. apereoides is associated primarily with granitic outcroppings (Streilein, 1982d). In Bolivia, T. apereoides inhabits flat and arid shrub-dominated habitat devoid of large rocks (Anderson, 1997). It is a crepuscular species (Eisenberg and Redford, 1999). In Brazil, its reproduction occurs throughout the year with two or three litters of one to six young (average 3.1) produced after a gestation period of 89 days (Eisenberg and Redford, 1999). Sexual maturity is reached between seven and nine months (Eisenberg and Redford, 1999).
