[1][2] Andrews's three-toed jerboa grows to a length of 113 to 130 mm (4.4 to 5.1 in) with a tail rather longer than its body and a weight of about 60 grams (2.1 oz).

The tail is thickened by the adipose tissue beneath the skin and has a flattened, terminal, black bushy section.

It can be distinguished from the rather similar thick-tailed three-toed jerboa (Stylodipus telum) by the fact that it has premolars in the upper jaw, these being vestigial in S.

It inhabits semi-arid and arid steppes and grassland, as well as sand dunes with scrubby vegetation.

[3] Andrews's three-toed jerboa has a wide range and presumed large total population and occurs in a number of protected areas.
