Myomimus setzeri Rossolimo 1976

Remarkably little is known about the habits and ecology of Setzer's mouse-tailed dormouse (2) (3). Unlike other dormice, species belonging to the genus Myomimus are not specialised for a life in the trees, and appear to live instead on and under the ground (2). Like other dormice, Setzer's mouse-tailed dormouse is assumed to hibernate over winter, accumulating fat beforehand which will sustain them through the long winter sleep (4). The breeding period of Setzer's mouse-tailed dormouse is believed to extend from April until June, and the female's seven pairs of mammae suggest that they give birth to a large number of offspring (2).

There are no known conservation measures currently in place for this species.

Looking somewhat like a cross between a mouse and a vole (3), Setzer's mouse-tailed dormouse can be distinguished from other dormice by its mouse-like tail, sparsely covered with short white hairs (2). The soft fur on the upperparts is a blend of ochre and grey, while the underparts, sides of limbs, and feet are white (2).

Myomimus dormice inhabit open country with clusters of trees and bushes, including the edges of grain fields, orchards, gardens and river banks. Most specimens have been found on trees, especially mulberry (2).

Setzer's mouse-tailed dormouse occurs in north-western Iran (2).

Classified as Endangered (EN) on the IUCN Red List 2007 (1).

Suitable habitat for this little-known dormouse is already limited, and is believed to be declining (2). Agricultural expansion, overgrazing, over-harvesting of woody plants for fuel, and military operations are just some of the human activities that may be having a detrimental impact on the dormouse's habitat (5).

The Setzer's mouse-tailed dormouse (Myomimus setzeri) is a species of rodent in the family Gliridae. It is endemic to Iran. Very little information is available for this species, with only 10 specimens known. It is found mainly in the pellets of the Eurasian eagle owl.
