Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| D. R. Prothero 2009 | arger peccaries (M1-3 length = 44-58 mm) with weak sagittal crests and relatively dolichocephalic skulls with robust occiput and zygomatic arches relative to Perchoerus; small to large diastemata between the canines and first premolars, and sometimes between Pl/pl and P2/p2; M3 with relatively large posterior cingulum and well developed postero-intemal heel, resulting in more elongate tooth than M3 of Perchoerus. |
