| G. M. Martin et al. 2024 | Palaeothentoid marsupial with a very long anterior mandibular region, with a distance between the procumbent incisor alveolus and the anteriormost alveolus of m1 equal (or longer) to the molar toothrow; large and deep anterior mental foramen located labially below the alveolus of the third unicuspid tooth that opens anteriorly, m1 is slightly longer than m2, the trigonid and talonid of m1-m3 are subequal, and with a larger trigonid in m4.
