Abstract

The micro land snail genus Diplommatina (family Diplommatinidae) is widely distributed in Southeast Asia and includes many endemic species. Three new species of Diplommatina are described from Satun Province in southern Thailand. Diplommatina bulonensissp. nov., D. laemsonensissp. nov. and D. prakaiphetensissp. nov. are distinguished from other species in the genus by their shell size and shape, the number of radial ribs on the penultimate whorl, the number of whorls, and features of the peristome. The agreement between phylogenetic tree based on analyses of COI and 16S sequences and comparative morphology support the delineation of these new species which, when compared to related species, belong to well-differentiated clades. The K2P distance between any of the three new species and other Diplommatina species included in the molecular phylogenetic analysis was at least 5.5% in COI and 3.9% in 16S. Two of the three new species (D. prakaiphetensissp. nov. and D. bulonensissp. nov.) are apparently endemic to Prakaiphet Hill and Bulon Pai Island, respectively. Additionally, we documented a new regional record for D. naiyanetri in Satun Province. These new species and records contribute to the knowledge of Thailand’s land snail biodiversity and highlight the need of conservation protections for regional karst habitats.

1849年泰国萨敦省陆地蜗牛属三新种的首次记录和描述(蜗牛足纲，蜗牛科)

微蜗牛属(微蜗牛科)广泛分布于东南亚，有许多特有种。报道了泰国南部沙敦省三新种。Diplommatina bulonensissp。11月，d.l aemsonenissp。D. prakaiphetensisp .;十一月在其壳的大小和形状、倒数第二轮上的放射状棱的数目、轮的数目和花圈的特征上区别于该属的其他种类。基于COI和16S序列分析的系统发育树与比较形态学的一致支持了这些新种的描述，与近缘种相比，这些新种属于分化良好的分支。在分子系统发育分析中，这3个新种与其他外交家种的K2P距离在COI和16S上分别至少为5.5%和3.9%。三个新种中的两个(D. prakaiphetensissp.)。11 .和d.b lonenissp。11月)分别是Prakaiphet Hill和Bulon Pai Island特有的。此外，我们还在沙屯省记录了一种新的奈亚纳特里虫区域记录。这些新物种和记录有助于了解泰国陆地蜗牛的生物多样性，并突出了对区域喀斯特栖息地进行保护的必要性。

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.
