巴塔哥尼亚森林爬行动物(Upucerthia Saturatior)是一种独特的爬行动物，生活在阿根廷中西部和邻近智利的Nothofagus Center of Endemisim的巴塔哥尼亚森林中。在1900年被描述为一个物种后，它很快就被归类为鳞喉型地龙的一个亚种，没有任何评论或研究，大多数后来的作者都遵循这种处理方法。根据U：Dumetaria内的一个明显的地理倾角和对已报道的U：Dumetaria和U saturatior之间的间层的形态和羽毛的重新分析，没有证据表明这些分类群之间的间层。Up ucerthia饱和度在鸣叫(“p-p-tirik-tirik”vs“pli-pli...”)、叫声(“pep”vs“Keep”)、形态(较小和较暗的黑色短喙与较大和较浅的棕色长喙)、独特的尾部模式、繁殖生境(森林边界与灌木草原和开阔的高地生境)以及迁徙模式(横跨安第斯山脉与南北走向)等方面也是Dumetaria的三倍。这些差异超过了耶氏原虫和阿尔比格氏原虫之间的差异，也远远大于耶氏原虫和瓦氏原虫之间的差异；它们压倒性地支持将饱和原虫列为一个完整的种。森林栖息物种的存在为测试物种形成过程中生境在干燥裸露生境和森林生境之间转移的作用(反之亦然)提供了机会。
The Patagonian Forest Earthcreeper (Upucerthia saturatior) is a distinctive furnariid that inhabits the Patagonian forests of central-western Argentina and adjacent Chile within the Nothofagus Center of Endemisim. After its description as a species in 1900, U. saturatior was quickly subsumed, without comment or study, as a Subspecies of the Scale-throated Earthcreeper (U. dumetaria), a treatment followed by most subsequent authors. On the basis of an apparent geographical cline within U: dumetaria and a reanalysis of the morphology and plumage of reported intergrades between U. dumetaria and U. saturatior, there is no evidence of intergradation between these taxa. Upucerthia saturation differs from U. dumetaria by its song ("p-p-tirik-tirik-tirik-tirik-tirik-tirik" vs. "pli-pli-pli-pli-pli..."), which is also three times faster in dumetaria, call ("pep" vs. "keep"), morphology (smaller and darker with a short black bill vs. larger and paler with a long brown bill), distinctive tail pattern, breeding habitat (forest borders vs. shrubby steppe and open highland habitats), and migration patterns (trans-Andean vs. north-south). These differences exceed those between U. jelskii and U. albigula and are far greater than those between U jelskii and U. validirostris; they overwhelmingly support ranking U. saturatior as a full species. The existence of a forest-dwelling species of Upucerthia parapatric to an open-country Upucerthia provides an opportunity for testing the role of habitat shift between dry exposed habitats and forest habitats (and vice versa) during speciation.
