The Lichtenstein jerboa ( Eremodipus lichtensteini ) is a rodent in the family of jerboa and the only species in the genus Eremodipus .
With a head-trunk length of 10 to 11 cm, a tail length of 12.8 to 15.5 cm and 5.0 to 5.4 cm long rear feet, the species is one of the medium-sized jerboa. The basic color of the fur on the upper side varies between straw and sand colors. There is a cinnamon to black pattern on it, which is caused by hair with brown-black tips. The underside and spots on the hips are white. The Lichtenstein jerboa differs from the actual desert jerboa ( jaculus ) in different details of the skull structure and the dentition, while the shape of the hind limbs is identical.
The range of the species extends from Turkmenistan over Uzbekistan to Kazakhstan . Smaller disjoint populations occur in Kazakhstan . Occasionally the population in the basin of Lake Balkhash is listed as a second subspecies in addition to the nominate form . The Lichtenstein jerboa lives in sandy deserts, which often have hilly landscapes. There she hangs on the edge of oases and in areas with isolated bushes or other vegetation.
This jerboa digs complex tunnel systems with several entrances, which are mostly adjacent to plants or in solid sand. Some corridors in the structure reach a depth of 60 to 80 centimeters. The Lichtenstein jerboa mainly eats seeds and, in times of rain (April – May), green parts of the plant. It hibernates for up to 6 months in the cold season . In females there is one litter with 3 to 8 pups per year.
The species recorded marked population fluctuations, with a low point every 10 to 12 years. It is listed by the IUCN as not at risk ( least concern ).
