The black field mouse ( Thaptomys nigrita , syn .: Akodon nigrita ) is a species of rodent from the group of New World mice that lives in South America .
Black field mice are stocky animals with short limbs and a short tail, whose physique is reminiscent of voles . Their fur is soft and dense, it is almost black in color, the underside is lighter.
Their distribution area includes the southeast of Brazil (from Bahia to Rio Grande do Sul ), the eastern Paraguay and the northeastern Argentina ( Misiones ). Their habitat are open habitats like grasslands, where they lead a partially burrowing way of life.
Traditionally, the species was assigned to the South American field mice ( Akodon ). According to genetic studies, however, it forms its own genus, Thaptomys , which may be more closely related to Necromys or the Cerrado mice ( Thalpomys ).
