Abstract

The Edwards and Edwards-Trinity Aquifers of Texas have diverse stygofauna, including fifteen species of snails found in phreatic and hyporheic habitats. These species have the hallmarks of adaptation to subterranean environments including extremely small body size and the loss of pigmentation and eyes. Here we use an integrative taxonomic approach, using shell, radula, and anatomical features as well as mitochondrial and nuclear DNA data, to circumscribe a new genus and two new cavesnail species from Central Texas. Vitropyrgus lillianaegen. et sp. nov. is described from Comal Springs (Comal County) and Fessenden Springs (Kerr County) and distinguished by a glassy, highly sculptured shell and distinctively simple, unornamented penial morphology. We also describe Phreatodrobia bullasp. nov. from Hidden Springs (Bell County), and several other springs in Bell & Williamson Counties, Texas. This species has a smooth, unsculptured teleoconch, a reflected and flared lip, and deeply concave operculum.

来自得克萨斯州爱德华兹和爱德华兹-特里尼蒂含水层的两种新的噬水蜗牛（软体动物门，腹足纲，蜗牛科

德克萨斯州的爱德华兹和爱德华兹-三位一体含水层有各种各样的蜗牛动物群，包括在潜水和潜栖栖息地发现的15种蜗牛。这些物种具有适应地下环境的特征，包括极小的体型和失去色素和眼睛。在这里，我们使用一个综合的分类学方法，利用壳、齿、解剖特征以及线粒体和核DNA数据，划定了一个新的属和两个新的洞穴甲种在德克萨斯州中部。Vitropyrgus lillianaegen。et sp. 11是从Comal Springs (Comal县)和Fessenden Springs (Kerr县)描述的，其特点是玻璃状，高度雕刻的外壳和独特的简单，无装饰的阴茎形态。我们还描述了大疱性挛缩。11月，从隐藏泉(贝尔县)和德克萨斯州贝尔和威廉姆森县的其他几个泉。本种有光滑，非雕刻的远螺，反射和喇叭唇，和深凹的被盖。

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.
