The species of Equus (Amerhippus) are revised using multivariate analysis of dental and autopodial remains, and some morphological characters of the skull and dentition. We recognize five species: E. (A.) andium, insulatus, neogeus, santaeelenae, and lasallei. They have been recorded in Argentina, Bolivia, Brazil, Colombia and Ecuador, through the Middle and Upper Pleistocene. They show peculiar adaptive features in the distal part of the extremities as a response to different environmental conditions.
