最近的一项利用线粒体和核DNA的地理学研究显示，在伊比利亚半岛存在两个明确的异域分支。使用单变量和多变量的统计分析，我们显示的证据形态分化的两个分支之间。尽管缺乏视觉上可诊断的形态特征，形态和分子数据表明，两个分支之间的分化显着足以防止在过去的基因流，因此保证一个特定的状态，为每两个分支。我们认为，地下生活的限制可能会增加经历神秘物种形成的机会，在蠕虫蜥蜴。为了建立一个分类重新安排的伊比利亚Blanus我们指定一个选择模式为B。产于伊比利亚半岛西南部的一新种;
A recent phylogeographic study using mitochondrial and nuclear DNA revealed the presence of two well defined allopatric clades of Blanus cinereus in the Iberian Peninsula. Using both univariate and multivariate statistical analyses, we show evidence of morphological differentiation between the two clades. Despite the lack of visually diagnosable morphological characters, the morphological and molecular data suggest that differentiation between the two clades was significantly enough to prevent in the past gene flow and therefore to warrant a specific status for each of the two clades. We suggest that the constraints of the subterranean life could increase the chances of experiencing cryptic speciation in worm lizards. In order to establish a taxonomic re-arrangement for the Iberian Blanus we designate a lectotype for B. cinereus from populations of central Iberia and describe a new species; Blanus mariae sp. nov. from southwestern regions of the Iberian Peninsula.
