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
M. Freudenthal et al. 1994Lower molars: In m1 the posterior branch of the protoconid is connected to the base of the metaconid or ending free; less frequently with a high connection to the metaconid. The sinusid is generally transverse. Second mesolophid rarely present. In m2 the mesolophid is never bifurcated. In m3 the mesolophid and mesoconid are absent. The metalophulid is often connected to the anteroconid, though in most cases to the anterolophulid. The posterior branch of the protoconid is nearly always long and free.
Upper molars: There is no connecting crest between mesoloph and metacone. Mesolophd in M1 and M2 generally of medium length. In M1 this mesoloph, together with a transverse crest from the mesostyl, gives the impression of a long, interrupted mesoloph. In M3 the protolophule is generally connected to the anterior border of the tooth; the mesoloph is well developed; the old entoloph is generally absent, the axioloph nearly always present (complete or incomplete). A small metacone is present.
