A new species of Atractus is described from grasslands of the State of Rio Grande do Sul, southern Brazil. The new species is distinguished from all congeners by the combination of a single postocular, long loreal, six supralabials, generally six infralabials, 17 dorsal scales rows, six or seven maxillary teeth, and a dorsal color pattern in preservative uniformly grayish-brown with a creamish-white temporal region. Comparisons of the new species are made with all other Atractus species, and its affinities with A. reticulatus and allied species are suggested based on the morphology of the hemipenis.
