A new species of the lizard genus Stenocercus Dumeril \& Bibron, 1837 is described based on six specimens from Serra da Canastra, Minas Gerais, southeastern Brazil. Similar to S. tricristatus (Dumeril, 1851), S. dumerilii (Steindachner, 1867), S. quinarius Nogueira \& Rodrigues, 2006, and S. squarrosus Nogueira \& Rodrigues, 2006, the new species has a pyramidal head and an enlarged, dorsally projected post-supraciliary scale, like a small horn. It is most similar to S. tricristatus, from which it differs in having a more elongated head in ventral view; a larger number of scales around midbody; a distinctly enlarged, smooth preauricular scale; and probably a larger body size. Moreover, the new species has distinctly keeled scales, with phylloid and mucronate dorsals; no enlarged supraoculars; no neck folds; a vertebral, and a pair of dorsolateral and (weak) lateral crests. A redescription of S. tricristatus is presented for comparison with the new species. (AU)
