Diagnosis
ReferenceDiagnosis
A. Averianov and P. Skutschas 2000Size relatively large (M2 length 2.09 mm), preparastyle small, cusps on ectocingulum except stylocone lacking, paracone and metacone with lingual slopes vertically oriented.

Differs from P. trofimovi Kielan-Jaworowska & Dashzeveg 1989 and P. minor Kielan-Jaworowska & Dashzeveg 1989 [both from the Albian of Mongolia] in being of somewhat larger size, in having a smaller preparastyle, in lacking additional cusps posterior to the stylocone on the ectocingulum, and in having more vertically oriented and shorter lingual slopes of paracone and metacone.
