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 1994Lower molars - Cingulum ridges, closing the valleys of the lower molars, well developed, often quite high; in m1 the lingual anterolophid is very well developed. The anterior metalophulid is nearly always absent. In m1 the anterolophulid forms an angle with the longitudinal axis of the molars. The mesolophid is of medium length or lon'; the ectomesolophid is nearly always present, often quite well developed. In m2 the protoconid hind-arm always ends free; it is nearly always long. The mesolophid is generally absent, less frequently present, and it may even be long. In m3 there is almost never an ectomesolophid.
Upper molars - The anterocone of M1 is quite frequently more or less subdivided; the prelobe forms a very maked angel with the border of the protocone. There frequently is a well-developed anterior spur on the paracone, that may reach the anterocone. The sinus of M1 and M2 is directed strongly forward in most cases. The connection of the entoloph with the protocone in M2 is nearly always low, or interrupted.
