A new species of lizard of the saxicolous and viviparous genus Phymaturus from Patagonia is described. The new species is a member of the Phymaturus patagonicus species group distributed on volcanic plateaus, mountains or rocky outcrops of southern Argentina. Phymaturus yachanana sp. nov. differs from the other members of the patagonicus group by a dorsal pattern of small and medium-sized white spots on a brown background, the number of scales around the midbody, genetic differences in mitochondrial and nuclear markers, and allopatric geographic distribution in an isolated group of hills. As other species of the group, the new species is viviparous and herbivorous.
描述了一种来自巴塔哥尼亚的石生胎生蜥蜴属（Phymaturus）新物种。该新物种是分布在阿根廷南部火山高原、山脉或岩石露头的巴塔哥尼亚蜥蜴物种组的成员。新物种雅查纳纳叶口蜥（Phymaturus yachanana sp. nov.）与巴塔哥尼亚蜥蜴物种组的其他成员不同，其背部在棕色背景上有中小型白色斑点图案，体中部周围的鳞片数量、线粒体和核标记的基因差异，以及在一个孤立的山丘群中的异域地理分布。与该物种组的其他物种一样，新物种是胎生且食草的。
