A new species of keel-headed amphisbaenian of the genus Anops is described from the Cerrado of the Jalapão region, Tocantins state, Brazil. This new species of Anops is described from a single specimen, which may be easily distinguished from the other species of the genus, Anops bilabialatus and Anops kingii, by showing an extremely narrow head (37.2% head length); a row of eight occipitals anterior to the first body annulus; temporal present; mental and postmental fused; four postgenial rows located between the malars; and two malars posterior to the second infralabial. The new species is the first of the genus found in the Cerrado core area, and, based on the available records, the single species in the genus may be restricted to this region.
