The brewer's gerbil ( Desmodilliscus braueri ) is a rodent of the long-tailed mouse family and the only species in the genus Desmodilliscus .

The species is similar to other gerbils in physique. It reaches a head-torso length of 4 to 7.5 cm and a weight of 6 to 14 grams. The 3.5 to 5 cm long tail is hairy, but not equipped with a tassel at the end. The fur color on the back is sandy brown and then gradually becomes lighter towards the whitish belly. In contrast to all other long-tailed mice, the brewer gerbil has three molars in the upper jaw and two molars in the lower jaw per half of the jaw. The species also differs from other gerbils in its skull structure.

The brewer gerbil lives in north-central Africa from Mauritania and Senegal on the Atlantic to Sudan on the Red Sea . She stays in the Sahel zone, which is characterized by a bushy savannah .

The underground structure of this rodent consists of several tunnels and chambers. The gerbil is usually observed at night before construction and hides in it during longer rainy seasons. Females are pregnant for 26 to 35 days and have two or three young per litter.

The IUCN lists the brewer gerbil as Least Concern .
