Abstract: This paper deals with a taxonomic study of the genus Tuarega Uvarov, 1943, with 2 new species, namely Tuarega sahara sp. nov. and Tuarega parisi sp. nov., from Sahara described. T. sahara sp. nov. is similar to T. insignis (Lucas, 1851), but it differs from the latter in four characters: the widest width of pronotum longer than length of metazona, median vein of tegmen not combined with cubital vein, radius vein of tegmen with 5 branches, cubital vein of tegmen with 2 branches. T. parisi sp. nov. is similar to T. insignis, but it differs from the latter in four characters: the widest width of pronotum longer than length of metazona, median vein of tegmen not combined with cubital vein, median vein of tegmen with 2 branches, cubital vein of tegmen with 2 branches. It is also similar to T. sahara sp. nov., but it differs from the latter by radius vein of tegmen with 7 branches and median vein of tegmen with 2 branches. A key to all known species of Tuarega is given. The type specimens are deposited in the Spanish National Museum of Natural Sciences (Museo Nacional de Ciencias Naturales, MNCN).
