Clethrionomys is a genus of small, slender voles.[2] In recent years the genus name was changed to Myodes, however a 2019 paper found that Myodes was actually a junior synonym for Lemmus, thus making it unusable. As such, Clethrionomys is re-established as the proper genus name.[2] At the same time, several species were moved to the genus Craseomys, so members of both genera are referred to as red-backed voles.[3] This genus was described by Johannes von Nepomuk Franz Xaver Gistel under the pseudonym "G. Tilesius". Some authors cite the taxonomic authority as "Gistel, 1850", whereas others still use "Tilesius, 1850".[4]
