Ungual tuft
In mammals, ungual tufts are tufts of hairs at the base of claws of the forefeet and hindfeet. Their presence has been used as a character in cladistic studies of the Cricetidae, a large family of rodents.[1]
Rice rats
Members of the tribe
Sigmodontomys aphrastus, and species of Holochilus have very reduced tufts or lack them entirely.[4]
Other examples
Among other South American cricetids, Abrawayaomys has long, dense ungual tufts.[8] The Tylomyinae are characterized by the presence of ungual tufts on their hindfeet.[9]
White ungual tufts are also present in the Philippine
Macrotarsomys has shorter tufts.[11] The Brazilian spiny rat Phyllomys sulinus has long, light gray ungual tufts.[12]
The tenrec Monodelphis handleyi has short ungual tufts.[14]
