Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| B. M. Davis 2012 | Differs from other peramurid genera in presence of strongly developed hypoconulid embrasure (cusps e and f) on m2 and m3; differs from Afriquiamus in smaller size, more lingually positioned metacone, presence of lingual cingulum and presence of three roots on upper molars; differs from Kouriogenys gen. nov. in two-rooted p1, and p4 mesiodistally longer than or equal to p5; differs from Peramuroides gen. nov. in larger size, large size difference between p3 and p4, and m1 trigonid angle of 90 degrees; differs from Tendagurutherium in absence of evidence for coronoid bone, and paraconid higher than metaconid; differs from Gen. et sp. indet. of Sigogneau-Russell (1999) in smaller size and in having transversely wider upper molars with a lingual cingulum and three roots. |
