We describe a new species of Liolaemus of the L. alticolor-bibronii group of the subgenus Liolaemus sensu stricto. We studied meristic, morphometric and qualitative pattern characters. Statistical tests were performed in order to evaluate morphological differences among the candidate species and the most closely geographically distributed species. Molecular analyses of Cyt-b mitochondrial gene were performed in order to estimate the position of the new species in relation to other taxa. We also recorded natural history data such as habitat, behavior, reproductive state, diet, and body temperature. Liolaemus absconditus sp. nov. differs from other species of Liolaemus in presenting a distinct combination of morphological character states of lepidosis and color pattern, being phylogenetically close to Liolaemus tandiliensis, Liolaemus gracilis and Liolaemus saxatilis. The new species is a saxicolous and endemic lizard of the Tandilia Mountain Range System of Buenos Aires Province.
我们描述了狭义Liolaemus亚属中Liolaemus alticolor - bibronii组的一种新的利奥蜥属物种。我们研究了可数、可量和定性模式特征。进行了统计测试，以评估候选物种与地理分布最接近的物种之间的形态差异。对细胞色素b线粒体基因进行了分子分析，以估计新物种相对于其他分类群的位置。我们还记录了自然历史数据，如栖息地、行为、繁殖状态、饮食和体温。新物种隐匿利奥蜥（Liolaemus absconditus sp. nov.）在鳞片病和颜色模式的形态特征状态上呈现出独特的组合，与其他利奥蜥属物种不同，在系统发育上与坦迪利利奥蜥（Liolaemus tandiliensis）、细利奥蜥（Liolaemus gracilis）和岩栖利奥蜥（Liolaemus saxatilis）接近。新物种是布宜诺斯艾利斯省坦迪利亚山脉系统的一种石栖特有蜥蜴。
