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. urn:lsid:zoobank.org:act:29B39613-3298-4B43-A13A-9F950051BD04 urn:lsid:zoobank.org:act:A97A5AA8-7295-4882-9809-CEFAD72E7202

通过综合分类学增加对盐环境居民的了解:新阿根廷地方性 Liolaemus(鬣蜥:Liolaemidae)及其进化关系

Liolaemus 属的已知多样性继续增加,这主要是由于其特有的高度、研究人员数量的增加以及该属的分类学和系统发育知识的进步。这种多样性使 Liolaemus 成为第二大物种丰富的四足动物属。目前的工作通过描述阿根廷普纳盐环境特有的两个新物种,为 Liolaemus 的多样性提供了更多证据。这两个物种都是 Eulaemus 亚属内的 Liolaemus montanus 组的成员。为了确定这些蜥蜴的分类地位,我们使用综合分类法作为工具,结合了系统发育、形态学和分子遗传学证据,以及半扁桃体的解剖结构、统计形态分析和生态特征。我们的分析支持了以下结论:两个采样的蜥蜴种群都是科学上的新物种。其中之一位于卡塔马卡省的安托法拉盐沼和萨尔塔省的 Hombre Muerto 盐沼的边缘。其他新物种栖息在由枸杞种植的盐碱地,主要是在安托法拉盐滩的盐壳之间。这两个物种都是中小型,可以通过独特的形态特征组合与 L. montanus 组的所有其他物种区分开来,主要是 pholidosis 以及背侧和腹侧的颜色模式。urn:lsid:zoobank.org:act:29B39613-3298-4B43-A13A-9F950051BD04 urn:lsid:zoobank.org:act:A97A5AA8-7295-4882-9809-CEFAD72E7202 其中之一位于卡塔马卡省的安托法拉盐沼和萨尔塔省的 Hombre Muerto 盐沼的边缘。其他新物种栖息在由枸杞种植的盐碱地,主要是在安托法拉盐滩的盐壳之间。这两个物种都是中小型,可以通过独特的形态特征组合与 L. montanus 组的所有其他物种区分开来,主要是 pholidosis 以及背侧和腹侧的颜色模式。urn:lsid:zoobank.org:act:29B39613-3298-4B43-A13A-9F950051BD04 urn:lsid:zoobank.org:act:A97A5AA8-7295-4882-9809-CEFAD72E7202 其中之一位于卡塔马卡省的安托法拉盐沼和萨尔塔省的 Hombre Muerto 盐沼的边缘。其他新物种栖息在由枸杞种植的盐碱地,主要是在安托法拉盐滩的盐壳之间。这两个物种都是中小型,可以通过独特的形态特征组合与 L. montanus 组的所有其他物种区分开来,主要是 pholidosis 以及背侧和腹侧的颜色模式。urn:lsid:zoobank.org:act:29B39613-3298-4B43-A13A-9F950051BD04 urn:lsid:zoobank.org:act:A97A5AA8-7295-4882-9809-CEFAD72E7202 主要在安托法拉盐滩的盐壳之间。这两个物种都是中小型,可以通过独特的形态特征组合与 L. montanus 组的所有其他物种区分开来,主要是 pholidosis 以及背侧和腹侧的颜色模式。urn:lsid:zoobank.org:act:29B39613-3298-4B43-A13A-9F950051BD04 urn:lsid:zoobank.org:act:A97A5AA8-7295-4882-9809-CEFAD72E7202 主要在安托法拉盐滩的盐壳之间。这两个物种都是中小型,可以通过独特的形态特征组合与 L. montanus 组的所有其他物种区分开来,主要是 pholidosis 以及背侧和腹侧的颜色模式。urn:lsid:zoobank.org:act:29B39613-3298-4B43-A13A-9F950051BD04 urn:lsid:zoobank.org:act:A97A5AA8-7295-4882-9809-CEFAD72E7202
