Diagnosis
ReferenceDiagnosis
M. Vucetich et al. 2015Small caviomorph similar in size to Garridomys curunuquem Kramarz et al., 2013, and Eoviscaccia Vucetich, 1989. Cheek teeth protohypsodont, but with crowns lower than in Garridomys and Eoviscaccia; two persistent labial fossettes in upper teeth, different from Eoviscaccia; posterior labial fossette as large as the hypofossette, different from G. curunu- quem; hypoflexus/id closing well above the base of the tooth forming a hypofossette/id; enamel thick and homogeneously distributed becoming thinner only on the posterior wall with age, different from G. curunuquem and Eoviscaccia; p4 with the trigonid much narrower than the talonid different from G. curunuquem and Eoviscaccia; cement absent as in Incamys Hoffstetter and Lavocat, 1970; mental foramen absent, different from G. curunu- quem and Eoviscaccia boliviana Vucetich, 1998, diastema more excavated than in G. curunuquem; lower incisor more robust than in G. curunuquem.
