ReferenceDiagnosis
J. E. Storer 2019Similar in size and crown height to Cupressimus barbarae; p4 trigonid valley open anteriorly; short anterior cingulid on anterior face of protoconid; metalophulid II convex posteriorly, creating a more elongate trigonid basin than in C. barbarae; metalophid on m1-2 straighter (less sinuous) than in the holotype of C. barbarae; ectolophid connection with hypoconid/hypolophid weaker than in C. barbarae.
