• Winge's concept of the genus Calomys essentially included unspecialized species with pentalophodont molars, which are characterized by the presence of a crest known as the mesoloph on the upper and mesolophid on the lower molars, and excluded species now placed in Calomys, which he classified in Hesperomys instead.
• Unlike in many other rice rats, including Handleyomys alfaroi and Euryoryzomys species, the mesoflexus on the second upper molar, which separates the paracone (one of the main cusps) from the mesoloph (an accessory crest), is not divided in two by an enamel bridge.
• As in M1, the paracone is connected to the front or middle of the protocone, the mesoloph is well-developed, and the valleys meet at the midline of the tooth.
• This tooth is characterized by four major cusps (protocone, paracone, hypocone, and metacone) and lophs or crests (protoloph, mesoloph, metaloph, and posteroloph), separated by synclines or valleys.
