The known diversity of the genus Liolaemus continues to increase, principally due to its great degree of endemism, the increasing number of researchers working on it, and advances in the taxonomic and phylogenetic knowledge of the genus. This diversity positions Liolaemus as the second most species-rich tetrapod genus. The present work adds to evidence for the great diversity of Liolaemus through the description of two new species, endemic to saline environments in the Argentinian Puna. Both species are members of the Liolaemus montanus group within the subgenus Eulaemus. To determine the taxonomic status of these lizards, we used integrative taxonomy as a tool, incorporating phylogenetic, morphological, and molecular genetic evidence, as well as the anatomy of hemipenes, statistical morphological analysis, and ecological characteristics. Our analyses supported the conclusion that both sampled populations of lizards are species new to science. One of these is found along the margins of the Antofalla salt flats in the Catamarca Province and the Hombre Muerto salt flats in the Salta Province. The other new species inhabits saline habitats vegetated by Lycium humile, principally between the salt crusts of the Antofalla salt flats. Both species are small to medium sized and can be distinguished from all other species of the L. montanus group by unique combinations of morphological characters, primarily pholidosis and dorsal and ventral colour patterns.

Liolaemus属的已知多样性继续增加，这主要是由于其特有程度高，研究该类的研究人员的数量增加以及该属的分类学和系统发育知识的进步。这种多样性将柳叶菜属定位为第二物种最多的四足动物类。目前的工作通过描述阿根廷普纳盐碱环境特有的两个新物种，为廖志鱼的巨大多样性提供了证据。这两个物种都是Eulaemus属的Liolaemus montanus组的成员。为了确定这些蜥蜴的分类学地位，我们使用综合分类学作为工具，将系统发育，形态学和分子遗传学证据以及半足类动物的解剖，统计形态学分析和生态特征结合在一起。我们的分析支持这样一个结论，即两个抽样蜥蜴种群都是科学新物种。其中之一是在卡塔马卡省的安托法拉盐沼和萨尔塔省的翁布勒·穆尔托盐沼的边缘发现的。其他的新物种则居住在枸杞，洋甘菊所生的盐碱生境中，主要位于安托法拉盐滩的盐壳之间。两种物种均小至中等大小，可与所有其他的莫塔氏乳杆菌（L. montanus）物种区分开来 按形态特征的独特组合进行分组，主要是卵磷脂和背侧和腹侧颜色模式。
