We describe Liolaemus attenboroughi sp. nov., a lizard distributed in the northwestern Patagonian Steppe of Chubut province (Argentina) previously confused with L. kingii (Bell 1843). Recent studies based on molecular evidence supports its evolutionary independence. Here we provide a morphological diagnosis of this lineage, comparisons between three molecular species delimitation methods, and an updated phylogeny of the L. kingii group. Based on current knowledge of its distribution, this new species is allopatric with geographically close species of the L. kingii group.
我们描述了一种分布在阿根廷丘布特省西北部潘塔哥尼亚草原的蜥蜴 Liolaemus attenboroughi sp. nov.，此前它与 L. kingii (Bell 1843) 混淆。最近基于分子证据的研究支持其进化独立性。在这里，我们提供了这条谱系的形态学诊断，三种分子物种划分方法之间的比较，以及 L. kingii 组的更新系统发育。根据目前对其分布的了解，这种新物种与地理上接近的 L. kingii 组物种是异域分布的。
