Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| R. Pascual and M. Bond 1981 | Dientes superiores anteriores al P3 desconocidos; P3 menos hipertrofiado que en los Epidolopinae y más comprimidos lateralmente; M1 de corona cortante (Polydolops) o cuadrangulares o multicuspidados, generalmente con 3 cúspulas labiales; M4 multicuspidados, más reducidos que los anteriores, pero menos que en los Epidolopinae, o aparentemente agrandados (Eudolops). Aparentemente sólo un incisivo inferior, procumbente; dientes entre el incisivo y el p2 aparentemente ausentes; p2 semejante al de los Epidolopinae; p3 cortante, desde muy hipertrofiado (Polydolops) hasta menos hipertrofiado (Eudolops); m1-3 multicuspidados y con el trigónido y el talónido desvanecidos; parte anterior del m1 más acuminado y elevada hacia el p3 que en los Epidolopinae; m2-3 generalmente con el trigónido a dos cúspides externas y una interna; m4 ausente. |
