The common hare ( Pygeretmus pumilio ), also known as a tabargan, is not a hare , despite its name , but a jerboa . It is controversial whether the common hare within the fat- tailed jerboa ( Pygeretmus ) belongs to the sub-genus Alactagulus or whether this forms its own genus.

Earth rabbits are small jerboa with a head-trunk length of 9 to 12 centimeters, plus a 11 to 18 centimeter long tail. The weight is 35 to 50 grams. The very long tail ends in a conspicuous tassel. This is dark with a white tip. The hind feet are developed into strong spring legs. The two outer toes are reduced in size on the hind feet. The fur is beige-brown on top and white on the underside.

The earth hare is widespread in the Central Asian steppes. Its distribution area extends from the Don via Kazakhstan to Inner Mongolia . This is where the nocturnal animal builds its burrows. While some structures are created temporarily as places of refuge, there is always a permanent structure that leads via a corridor up to six meters long into a nest chamber that is about 30 to 70 centimeters below the surface of the earth. The chamber is padded with plant material. The food consists of roots and tubers, some of which are stored in the burrows.

Reproduction takes place between March and September. Some females have two litters during this period. One to seven young animals (mostly 2–4) are born per litter. After reaching sexual maturity, females stay close to the mother's nest, while males migrate longer distances.

The dwarf fat-tailed jerboa is on the IUCN does not endanger the (least concern) listed.
