Portions of two mitochondrial genes (12S and 16S ribosomal RNAs) were sequenced to analyze the phylogenetic relationships of the <i>Mabuya</i> group from the Australian region (<i>Corucia</i>, <i>Egernia</i> and <i>Tiliqua</i>). Results indicated the monophyly of these genera and their divergence from Asian and African members of this group. This suggests that the diversity of the <i>Mabuya</i> group in the Australian region has increased through an endemic radiation, not through multiple colonizations from outside. Among the genera from this region, <i>Corucia</i> and <i>Tiliqua</i> were closest to each other. This result contradicts with those of the previous hypotheses on the basis of morphological and immunological data that, respectively, suggested closest affinities between <i>Corucia</i> and <i>Egernia</i>, and <i>Egernia</i> and <i>Tiliqua</i>. We suppose that the morphological characters exclusively joining <i>Corucia</i> and <i>Egernia</i> are actually in plesiomorphic state.<br>
