Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| F. J. Goin and A. M. Candela 2004 | Rumiodon inti differs from other didelphimorphians in the following combination of characters: upper molars much longer than wide, with reduced protocones and well-developed postmetacristae; centrocrista with labial vertex ending very close to labial face of the tooth; paracone and metacone well separated; paraconule vestigial or absent; metaconule reduced; stylar shelf reduced; StA, StB, StC, and StD, at least in M1, anteroposteriorly aligned and labiolingually compressed; StB subequal to StD and larger than StC, which is, in turn, larger than StA. |
