If no rank is listed, the taxon is considered an unranked clade in modern classifications. Ranks may be repeated or presented in the wrong order because authors working on different parts of the classification may disagree about how to rank taxa.
|W. W. Korth and C. Branciforte 2007||Skull features distinct from other florentiamyines (from Wahlert 1984): no flange on frontals above orbits; posterior palatine, dorsal palatine, optic and sphenopalatine foramina more anteriorly placed; incisive foramen smaller (length approximately 12% total length of upper diastema). Dental features: cheek teeth submesodont, similar in crown height to Proheteromys but cusps more bunodont; premolars sim- ple; P4 with simple protoloph (consisting of circular protocone and occasional minute cuspules); P4 consists of four main, subequal cusps (no protoconid) with occa- sional minute accessory cuspules; transverse valley of molars relatively shallow, lophs uniting centrally after only moderate wear; lingual cingulum on upper molars continuous (not interrupted by transverse valley).|
