The description of Liolaemus shitan was made based on an exhaustive morphological diagnosis. However, due to the lack of molecular evidence, a later phylogeographic study suggested that L. shitan would not be a valid species, but rather a synonym for L. elongatus. Here, after careful examination, we show numerous evidences of external morphology, coloration, physiological data and distribution, which would indicate that L. shitan is a valid species different from L. elongatus. Therefore, we consider L. shitan as a valid species.
