Diagnosis
ReferenceDiagnosis
R. M. Schoch 1984Medium-sized tapirs (smaller than Tapirus terrestris); dentition similar to that of Tapirus,
but teeth lower-crowned (relatively brachyodont); lower cheek teeth elongated anteroposteriorly; M2_3 trigonids and talonids separated by a deep groove or constriction; maxilla relatively deep as compared to Tapirus; lachrymal processes less prominent than in Tapirus; sulcus on the lateral face of the ascending portion of the maxilla shallower and more constricted than in Tapirus; mandibular symphysis narrow relative to Tapirus.
