The land area of Laos is composed of a large variety of undisturbed habitats, such as high mountainous areas, huge limestone karsts and the lower Mekong Basin. Therefore, Laos is expected to have a high species diversity, especially for the land snails. However, with respect to research on malacology, Laos is probably the least well-researched area for land snail diversity in Indochina (including Laos) over the past few centuries. The handful of species lists have never been systematically revised from the colonial period to the present, so these classifications are outdated. Herein we present the first comprehensive annotated checklist with an up-to-date systematic framework of the land snail fauna in Laos based on both field investigations and literature surveys. This annotated checklist is collectively composed of 231 nominal species (62 'prosobranch' and 169 heterobranches), of which 221 nominal species are illustrated. The type specimens of 143 species from several museum collections and/or 144 species of newly collected specimens are illustrated. There are 58 species recorded as new to the malacofauna of the country, and two new replacement names are proposed as Inkhavilay and Panha, (Ariophantidae) and Inkhavilay and Panha, (Camaenidae). Four recently described species of the genus from Laos, "", "", "" and "" are synonymized with previously described species. In addition, thirteen nominal species are listed as uncertain records that may or may not occur in Laos. This annotated checklist may inspire malacologists to carry on systematic research in this region.
老挝的陆地面积由多种未受干扰的栖息地组成，如高山地区、巨大的石灰岩岩溶地貌以及湄公河下游流域。因此，老挝预计拥有高度的物种多样性，尤其是陆地蜗牛。然而，就软体动物学研究而言，在过去几个世纪里，老挝可能是印度支那（包括老挝）陆地蜗牛多样性研究最少的地区。从殖民时期至今，为数不多的物种名录从未得到系统修订，因此这些分类已经过时。在此，我们基于实地调查和文献研究，首次呈现了一份老挝陆地蜗牛动物群的全面注释清单，并带有最新的系统框架。这份注释清单总共包含231个名义物种（62个“前鳃亚纲”和169个异鳃亚纲），其中221个名义物种配有插图。展示了来自几个博物馆馆藏的143个物种的模式标本和/或新采集标本的144个物种。有58个物种被记录为该国软体动物区系的新物种，并且提出了两个新的替代名称，即Inkhavilay和Panha（阿瑞芬螺科）以及Inkhavilay和Panha（南亚田螺科）。最近在老挝描述的该属的四个物种“”、“”、“”和“”被同义化为先前描述的物种。此外，有13个名义物种被列为不确定记录，它们可能在老挝出现，也可能不出现。这份注释清单可能会激励软体动物学家在该地区开展系统研究。
