The ctenodactylids from the Lower and Middle Miocene of Saudi Arabia are represented by two species:Sayimys intermedius(Sen and Thomas, 1979) andSayimys assarrarensissp. nov. This new taxon differs from the other species ofSayimysby its larger size together with an association of characters such as the presence of a metalophulid II in d4 and the strength of the anteroloph and posteroloph in P4. A cladistic analysis involvingProsayimys flynni,Sayimys obliquidens,S. assarrarensissp. nov.,S. intermedius, S. sivalensis, S. baskini, andMetasayimys curvidensis provided.Sayimys assarrarensissp. nov. nests betweenSayimys obliquidensandMetasayimys curvidensas a relatively primitive taxon.
