A new scorpion species, Androctonus tinzaouatinensis sp. n. is described and illustrated from the hyperarid Saharan regions of the Tin Zaouatine District, In Guezzam Province and Timiaouine District, Bordj Badji Mokhtar Province, southern Algeria. This new species represents the first record of the genus Androctonus from the Timiaouine and Tin Zaouatine areas. It is compared with congeners from Algeria and Niger, notably A. ajjer Ythier, Sadine, Alioua & Lourenço, A. amoreuxi (Audouin), and A. eburneus (Pallary).
