Abstract

Alpine Arianta populations from the Biellese Alps in Italy are characterized by imperforate, thin-shelled, dark brown shells without or with sparse light spots that resemble widespread phenotypes of Arianta arbustorum arbustorum found in calcium-deficient areas. Therefore, they were not considered a distinct taxon. However, molecular phylogenetic analyses show that they belong to a group of subspecies of A. arbustorum from the Western Alps and the Pyrenees. We classify them as a distinct subspecies, Arianta a. doriae (Paulucci, 1878), which reduces the geographical gap between the western group of subspecies of A. arbustorum and the Eastern Alps where Arianta originated. This subspecies survived the glacials in a peripheral mountain refuge at the southern margin of the Biellese Alps.

一种被遗忘的陆地蜗牛亚种，来自西阿尔卑斯山的一个更新世避难所

来自意大利Biellese阿尔卑斯山脉的高山Arianta种群的特征是无孔，薄壳，深棕色外壳，没有或有稀疏的亮点，类似于在缺钙地区发现的Arianta arbustorum arbustorum的广泛表型。因此，它们不被认为是一个独特的分类单元。然而，分子系统发育分析表明它们属于来自西阿尔卑斯山和比利牛斯山脉的a . arbustorum亚种群。我们将它们归类为一个独特的亚种，即Arianta a. doriae (Paulucci, 1878)，这减少了arbustorum西部亚种群与Arianta起源的东阿尔卑斯山之间的地理差距。这个亚种在比耶利斯阿尔卑斯山脉南缘的外围山区避难所的冰河时期幸存下来。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
