The carmine-nosed rats ( Bibimys ) are a species of rodent living in South America from the group of New World mice with three species.
These rodents reach a head body length of 8 to 10 centimeters, the tail becomes 6 to 8 centimeters long and the weight is 23 to 34 grams. Their fur is dark brown on the upper side and has a black eel line , the belly and feet are colored light gray. The head is built relatively massive, the eponymous feature is the red colored nose.
Carmine-nosed rats are native to central Brazil and northeastern Argentina , where they inhabit grasslands and savannas. They are ground-dwelling animals that also partially dig in the ground. They are nocturnal and feed on grasses and seeds.
There are three known types, whereby the delimitation between the individual types is unsecured:
- Bibimys chacoensis is native to northeast Argentina.
- Bibimys labiosus is only known from central Brazil.
- Bibimys torresi lives in eastern Argentina.
The carmine-nosed rats are presumably closely related to Scapteromys and the South American giant rats ( Kunsia ), but are significantly smaller than these.
