The Rotnasenmaus ( Wiedomys pyrrhorhinos ) - not to be confused with the Rotnasenratten - is in Brazil living rodent species from the group of New world .
Red-nosed mice reach a head body length of 10 to 13 centimeters, their tail is 16 to 21 centimeters long. Their fur is gray-brown on the back and white on the belly. The nose, ears, rings around the eyes and the outside of the legs are colored red.
These rodents live in eastern Brazil, their range extends from Ceará to Rio Grande do Sul . They inhabit bush landscapes such as the caatinga . They are excellent climbers and at least partially lead a tree-dwelling way of life. They are nocturnal, during the day they rest in nests that they either take over from birds or build themselves. These nests are used collectively, 8 adult and 13 young animals were found in one nest.
The diet of these animals consists of seeds and insects.
The systematic position of the red-nosed mice within the Sigmodontinae is isolated. It is not closely related to any species and is therefore listed in its own tribe , Wiedomyini.
