Liolaemus barbarae was recently described from northern Chile. However, the character states used to distinguish this species from Liolaemus puna are not exclusive. We reassessed the character states used for the diagnosis of L. barbarae and compared these with data from the type series and additional specimens of L. puna. We found identical ranges or broad overlap in character states between the two species. We conclude that L. barbarae is a junior synonym of L. puna.
