Diagnosis
ReferenceDiagnosis
J. F. Sutton and W. W. Korth 1995Larger than Cupidinimus eurekensis, C. lindsayi, and C. nebraskensis , smaller than all other species; cheek teeth relatively low crowned (equivalent to those of C. lindsayi, C. whitlocki, and lower crowned than C. nebraskensis, the type species); accessory cuspules occur on P4 less frequently than in Great Plains species and more frequently than in C. whitlocki and more western species; hypostylid never present on P4 as in C. nebraskensis.
