In this study a new analysis of the chiliensis group (Liolaemidae) is made adding twenty four new characters to the previous matrix (now 83 characters) of Lobo (2001a) and seven species (now 79). The frequency values were updated for more than 50% of species included previously. Analyses were made considering equally weighted characters criteria and also using the implied weights of Goloboff (1993). A total of six analyses were made, following the “equally weighted characters” criteria and the weighting scheme (five runs, changing each time the value of the weighting constant K, from K=2 through K=6). In general, results of the present study are in agreement with those obtained in a previous study. In this study the nigromaculatus group is monophylethic while the elongatus and monticola groups are paraphylethic and the following monophylethic groupings are recognized: alticolor, altissimus, capillitas (including capillitas and three recently described new species), gravenhorsti, kriegi, leopardinus, nigromaculatus, nigroviridis, pictus, robertmertensi (including chiliensis, nitidus and robertmertensi) and tenuis.
