If no rank is listed, the taxon is considered an unranked clade in modern classifications. Ranks may be repeated or presented in the wrong order because authors working on different parts of the classification may disagree about how to rank taxa.

Diagnosis
ReferenceDiagnosis
R. H. Tedford et al. 2009Differs from M. merriami in smaller size; lyrate temporal crests that join posterior to frontoparietal suture in short, weak sagittal crest; occiput narrower with lambdoidal crests subdued; bullae larger relative to size of skull; I2 with weaker lateral cusplet and weaker lingual cingulum; denti- tion lower crowned; M1–M2 less quadrate with stronger labial cingulum on paracone of M1; M2 smaller relative to M1; m1 slenderer with less oblique paraconid, and narrow talonid; and m3 trigonid shorter relative to length of talonid.
