We describe a new species of Amphisbaena from the Caatinga of northeastern Brazil. The new taxon is identified mainly by having 216–239 body annuli, 13–17 caudal annuli without autotomic site, 4–8 (usually six) precloacal pores without a median hiatus, 18–24 dorsal and 18–24 ventral segments at a midbody annulus, 4 supralabials, 3 infralabials, and postmalar row present. The continued discovery of new amphisbaenians from Caatinga highlights the insufficient current knowledge regarding the diversity of this group in this semiarid region.
