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.

Diagnosis
ReferenceDiagnosis
O. Fejfar et al. 1998Medium sized eomyid with brachyodont molars, but higher crowned than Eomys Schlosser, 1884. The bunodont structure is replaced by lophodont transverse crests with narrow and deep synclines. Occlusal surface of more worn teeth in concave. Alveolar pattern of roots as in other Eomyids. The shape of the mandible differs in a longer diastema and longer and narrower rostrum. Lower dentition crowns slightly higher than in Eomys, with labial borders higher than the lingual sides. Both the anterolophid and the longitudinal (sagittal) crest are mssing, and syncline III is a deep transverse valley between two lobes. The p4 consists of three lobes: mesial, medial and distal;the mesial lobe (anterolophid and metalophid with a small remnant of sycline I), medial lobe (mesolophid, or protoconid-metaconid crest) and distal lobe (hypolophid, or lateral entoconid-hypoconid, oval basin like syncline IV, and posterolophid). The main deep valley, syncline III, is between the medial and distal lobe. In m1-2, the two lobes are of similar oval structure, with smaller basins of the same shape and diagonally-lingually inclined (approx. 10 degrees). The mesial lobe anterolophid is missing. The basins (mesially: syncline II, distally: syncline IV) are closed. The smaller distal lobe of m3 is narrow, producing a triangular shape.
