: A minute diastema occurs between P1 and P2 and P2 and P3. All upper premolars carry strong buccal and lingual cingula. In crown size: P3>P2>P1. Small anterior cingular cusps and posterior cusps occur on P1 and P2; P3 lacks an anterior cusp but exhibits a strong posterior cusp. P1 and P2 crowns are roughly oval in shape and carry a small post-lingual lobe and P3 carries a slightly larger medial-lingual lobe.

: M1: The posterior tip of P3 touches the parastylar corner of M1 anterior to, and against, the base of stylar cusp A, which is small. The anterior cingulum below stylar cusp B is short, broad and complete. Stylar cusp B is moderately well-developed. Stylar cusp C is small and broadly rounded. A minute protoconule is present at the base of the paracone apex. Stylar cusp D is large and rounded. Stylar cusp E is not visible on either the left or right M1. M1 shows a weakly developed posterior cingulum.

: The premolar row is relatively long and uncrowded, with the first two premolars narrowly separated and a larger gap between P2 and P3. P1-3 are moderately cingulated buccally and lingually. In crown height, P2 is taller than P1; P1 and P3 are subequal in crown height. Left and right P3 are double rooted and not transversely aligned in the tooth row. The crown of P3 possesses a small posterior cusp; P2 possesses a broader posterior cusp. All premolars are without anterior cusps. Both P1 and P2 are broad, with broadly rounded posterolingual lobing.

: M1: The M1 talonid is wider than the trigonid. The anterior cingulum is present but poorly developed, not uniting to form a complete buccal and posterior cingulum. A greatly reduced paraconid appears in occlusal view as a small sub-horizontal spur. The metacristid and hypocristid are roughly oblique to the long axis of the dentary. The cristid obliqua extends from the hypoconid to the posterior wall of the trigonid, intersecting the trigonid at a point well buccal to the point directly below the tip of the protoconid. There is a very small, broadly rounded entoconid. From the base of the metaconid posteriorly, the talonid endoloph follows the line of the dentary to the entoconid, but with a buccal orientation, until reaching the base of the hypoconulid.

The anterior cingulum is as in M2; the buccal cingulum is absent; the posterior cingulum is absent. The metaconid is slightly taller than the paraconid, and both are much shorter than the protoconid. The weak hypoconid of the M4 talonid is greatly reduced and indefinable. The entoconid is present but minute and broadly rounded. The cristid obliqua forms a low, weak crest which contacts the trigonid wall slightly lingual of the metacristid fissure. A notable feature of M4 morphology is the reduction of the talonid crown enamel and absence of buccal cingulum below the cristid obliqua, which causes the talonid to appear as a narrow spur jutting off the trigonid wall. From the base of the metaconid posteriorly, the endoloph of M4 exhibits greater buccal orientation away from the line of the dentary compared with any other lower molar.</paragraph>
