Atyaephyra desmarestii is a species of freshwater shrimp in Europe.
Atyaephyra desmerestii is a small crustacean, measuring on average about 3 centimeters in size, and a maximum size of 4 centimeters.
Atyaephyra desmerestii is found in most of central and southern Europe, although it is not found in the UK and Denmark. There are also scattered populations in northern Africa.
The species was first described by P. A. Millet in 1831 as Hippolyte desmarestii. In 1867, de Brito Capello established a new genus Atyaephyra which included H. desmarestii as Atyaephyra desmarestii.
