Diagnosis
ReferenceDiagnosis
E. R. Dumont and T. M. Brown 1997Larger than Pithiculitis minimus and P. rothi. Lower m1 bladelike, exhibitin three denticles (as does P. minimus) and four striations. Denticles are apically positioned, lending trigonid a more squared outline than in P. minimus. Lower m1 talonid uniquely possesses three mesiodistally aligned capsules, but the lingual edge of the m2 and possibly m3 talonid is composed of three small cuspules as in P. minimus
