Diagnosis
ReferenceDiagnosis
M. O. Woodburne 1969Smallest species of genus; upper and lower molars not markedly expanded transversely and M' not reduced as in C. occidentale, new species; no strong postmetaconid crest on lower molars and dP4 as in C. proterva; differing from all other species in that P4 lacks a bicusped heel and P4 lacks a deep, trenchant, postprotoconal groove. Bases of molar protocones and hypocones acuminate lingually.
D. R. Prothero 2015[Same as for genus] Smallest of all the hesperhyines (see Tables 5-8); narrow plesiochoanal fossa; retains P3 with a narrow lingual cingulum.
