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
B. Engesser 1972Gliridae-species medium in size, from M3 to M1 masticatory surface of the teeth is more and more concave.
Lower molars: two-rooted, strong main ridges, in average four secundary ridges. Main ridges bigger on labial side; on lingual side with interrupted endolophid. The centrolophid is not connected to mesolophid-ridge. The two most anterior main ridges on the labial side mostly are not connected. P4 inf.: big, compared with other species. M1 inf: anterior only slightly narrower. M2 inf.: mostly broader than M1 inf., broadest in the frontal part. M3 inf: relatively elongated.
Upper molars: nearly completely square-like in outline, labial side never with strong flexae. Endolph not interrupted. Main ridges higher than secundary ridges. Mostly four secundary ridges. Anterior middle ridge on lingual side always connected to endoloph, on labial side mostly unconnected. The two most anterior main ridges, as well as the two most posterior, nearly always connected with each other. Lingual side ornamented. P4 sup. roundish in outline; 4 main ridges are connected with a short endoloph. Strong anterior middle ridge does not reach the endoloph. Lingual side also ornamented. M1 sup.: nearly square-like, anterior inner corner on lingual side more rounded than the other corners. The both anterior main ridges slightly directed anterior, the both posterior are orietated perpendicular to the endoloph. M2 sup. nearly square-like, posterior slightly rounded, transverse ridges all considerably parallel to each other and perpendicular to the endoloph. M3 sup.: posterior rounded more stronly than M2, the transverse ridges - with the exception of antero- and posteroloph - are slightly inclined to the front.
