Diagnosis
ReferenceDiagnosis
R. Daams and M. Freudenthal 1988On the average smaller than M. gregarius and larger than M. minor. The anteroconid is slightly or deeply split in more than half the specimens. The mesolophid in m1 is short or absent, rarely longer. M1 always has a split anterocone, and almost always protolophule and metalophule point backwards. Generally there is a spur on the posterior wall of the paracone.
