The type species is A. paludalis, named by Lev Nesov in 1981 from remains discovered in the Kyzyl Kum desert of Uzbekistan.[2] At first, he tentatively described the fossil material as the jaw fragments of a ctenochasmatidpterosaur (a flying reptile), but reinterpreted Aidachar as a fish in 1986.[2][3] The second species, A. pankowskii, is described from Kem Kem Group of Morocco and reclassified from the genus Cladocyclus, to which it is thought to be closely related.[4][5]
