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

R. Daams and H. De Bruijn 1995No darkening around eyes and ears (neither stripe nor spot present).
Tail thin, as in rats, covered with very short, even white hair growing thickly along tail shaft; rings on skin visiblc with Icns. Skull elevated on line of upper profile, and markedly shortened rostrally. Occipital region rounded. Interorbital region somewhat compressed due to ovally elongated depressions near basis of nasals, i.e., at the anterior part of infraorbital region. Auditory bullae large and inflated, much larger than in Muscardinus. Jugal bone forms sharp proccss protruding anteriorly and not quite reaching lateral contour of lacrimal. Infraorbital foramen very small and narrow, appreciably smaller than in Muscardinus. Angular process of lower jaw with small round aperture in wall.
Crowns of molars flat, inner and outer margins not elevated. Crowns of M1 and M2 of very similar structure. cacli with fivc transverse enamel folds: first two fairly long with inner margins pointing posteriorly; ncxt two folds form deep bend reaching middle of tooth; last (fifth) fold extends along posterior margin of tooth, its inner tip bending somewhat anteriorly. This crown structure little resembles that of other dormice. Premolar of lower jaw small, its outer margin directed obliquely anteriad. Four transverse ridges on surface, two internal ones forming closed arching protrusions directcd posteriorly. Premolar of lower jaw small, below level of rest of toothrow (differing in this from other dormice); three barely visiblc ridges on surface.
