Abstract: We describe a new species of aetosaur, Redondasuchus rineharti, based on isolated scutes and an incomplete femur from a single locality in the Upper Triassic Redonda Formation of east-central New Mexico. R. rineharti is distinguished from R. reseri, the only other species of Redondasuchus, by its scute morphology, specifically by its large size, presence of a boss at the point of flexure and mediolaterally-oriented row of pits immediately posterior to the anterior bar. Various workers have proposed that Redondasuchus should be synonymized with Typothorax coccinarum, but we review their arguments and find no justification for this synonymy.
