Prometheomys Satunin, 1901 . Zool. Anz., 24:572.

TYPE SPECIES: Prometheomys schaposchnikowi Satunin, 1901 .

COMMENTS: The only extant member of an archaic line of the arvicoline radiation, which most specialists isolate as the tribe Prometheomyini within Arvicolinae (Gromov and Polyakov, 1977; Hooper and Hart, 1962; Kretzoi, 1969; Pavlinov and Rossolimo, 1987; Zagorodnyuk, 1990). Repenning et al. (1990), however, aligned Prometheomys with another presumed relic, Ellobius, in the subfamily Prometheomyinae .
