Diagnosis
ReferenceDiagnosis
R. K. Stucky and L. Krishtalka 1990Differs from all other species of Bunophorus (except B. grangeri) in having prominent paraconid on PcM3 and less bunodont molar cusps; differs from B. grangeri in having a paraconid on P4• Additionally: P4 not as inflated as in B. etsagicus, B. macropternus; unlike B. sinclairi, P4 lacks metaconid, M2_3 cristid obliqua strong and complete; much smaller than B. grangeri, B. etsagicus, B. sinclairi and slightly smaller than B. pattersoni, B. macropternus.
