Sceloporus subniger Poglaygen Smith is a montane bunchgrass lizard distributed across pine-oak forests of central Mexico. Prompted by the discovery of a new population of this lizard in far western Mexico, and by recent studies suggesting S. subniger may be a composite of several distinct species, we examined in more detail the genetic structure of S. subniger. We generated a mitochondrial DNA (mtDNA) dataset from 81 specimens and an ultraconserved elements (UCE) dataset representing thousands of genomic regions from 12 specimens to specifically evaluate the genetic distinctiveness of populations from western Michoacán and adjacent Jalisco along with the newly discovered population in the Sierra de Mascota in western Jalisco. We also recorded morphological data from 47 museum specimens to compare to our genetic data. Results from our analyses of the genetic data, augmented by specimen measurements and scale counts, support the notion that S. subniger is indeed a composite of distinct species. Montane bunchgrass lizards from western Michoacán and adjacent Jalisco, and from the Sierra de Mascota in western Jalisco, each represent distinct new species, which we describe and name here.
黑纹草蜥 Poglaygen Smith 是一种分布于墨西哥中部松栎森林中的高山丛生草蜥。受在墨西哥西部发现的这种蜥蜴的一个新种群的启发，以及最近的研究表明，黑纹草蜥可能是由几个不同的物种组成的，我们更详细地研究了黑纹草蜥的遗传结构。我们从 81 个标本中生成了一个线粒体 DNA(mtDNA)数据集，并从 12 个标本中代表数千个基因组区域的超保守元件(UCE)数据集，专门评估了来自米却肯州西部和相邻哈利斯科州以及在哈利斯科州西部的马斯科塔山脉新发现的种群的遗传独特性。我们还记录了 47 个博物馆标本的形态数据，以便与我们的遗传数据进行比较。我们对遗传数据的分析结果，加上标本的测量和鳞片计数，支持了黑纹草蜥实际上是由不同的物种组成的观点。来自米却肯州西部和相邻哈利斯科州以及哈利斯科州西部的马斯科塔山脉的高山丛生草蜥，每个都代表了一个独特的新物种，我们在这里对其进行了描述和命名。
