Diagnosis
ReferenceDiagnosis
D. R. Prothero 2015[Same as for genus] Hesperhyine with a narrow plesiochoanal fossa, narrow posthamular part of the pterygoid, broad pterygoid process of the alisphenoid that joins the palate at a high angle, shallow orbitomaxillary fossa. It can be distinguished from other hesperhyines by its large lacrimal tubercle, and narrow lingual cingulum on P3.
