Muscardinus Kaup, 1829 . Skizz. Entwikel.-Gesch. Nat. Syst. Europ. Thierwelt, 1:139.

TYPE SPECIES: Mus avellanarius Linnaeus, 1758 .

SYNONYMS: Muscardinulus (see Thaler, 1966).

COMMENTS: Kratochvil (1973) proposed to place Muscardinus in its own subfamily, Muscardininae, based on the uniquely derived stomach anatomy, molar morphology, and phallic features. De Bruijn (1967) and Daams (1981) both included Muscardinus in the Myoxinae based on dental morphology. This arrangement was supported by the results of Wahlert et al. (In Press). Muscardinus appears to be most closely related to Myoxus (Wahlert et al., In Press). See also comment under Myoxinae .
