ResumoAbstract: Machairodonts represented by specimens from the Late Cenozoic of the Texas Panhandle include a small form of Machairodus ( Heterofelis ) from the Axtel locality (Hemphillian), and a new species, Ischyrosmilus johnstoni , from the Cita Canyon locality (Blancan). Ischyrosmilus , previously known only by two mandibles from California and Idaho, is shown by the new material to be closely related to Homotherium from the Villafranchian of Europe. Dinobastis , from the Middle and Late Pleistocene of Eurasia and North America, has close affinities with Homotherium and Ischyrosmilus . Five genera of machairodonts may now be recognized from the Pliocene and Pleistocene of North America: Sansanosmilus , Machairodus ( Heterofelis ), Ischyrosmilus , Dinobastis and Smilodon .
