The only obvious difference between the two is that "T. romana" has skin-covered eyes and it also has a caecoid pelvis, whereas "T. europaea" has a europoid pelvis. Although similar in body, the dentition of "T. romana" is obviously larger in size than that "T. europaea". Both the length of the tooth row and the individual elements are larger. Moreover, the mesotyle of the upper molars is generally divided. The dentition of "T. europaea" is small and the length of M1-M3 is less than 19% of the length of the condyle base. This mole also has relatively small molars for its size.
