摘要通过比较形态学、解剖学和线粒体DNA遗传学研究，我们在东帝汶鉴定了三种Landouria Godwin-Austen，1918。其中一个种被鉴定为L. cf Winteriana（Pfeiffer，1842），一种最初描述于爪哇的种，但被认为广泛分布于整个印度尼西亚群岛。另外两个种新描述为L.帝汶岛; sp.和L.蒙大拿; sp.，分别兰道氏花sp.与L. Winteriana，但不同的是一个较小的壳和细节的阴茎形态。蒙大拿兰道氏花sp.只在较高的海拔地区发现，并且很容易通过其独特的外壳区分。线粒体遗传学揭示了L.产于云南的omelastoma是巽他群岛所有物种的姐妹谱系。基于这一观察，我们保持系统的位置在Landouria的巽他群岛的物种，尽管在他们的生殖器解剖的一些微小的差异。此外，我们的系统发育表明，东亚属Aegista阿尔伯斯，1850可能是Landouria的姐妹分类群。然而，我们拒绝了Hirano等人的提议。（[2014]东亚发生的陆生蜗牛Aegista，Landouria，Trishoplita和Pseudobuliminus（肺螺目：Bradybaenidae）的形态学，分类学和分子生物学之间的实质性不一致。Molecular Phylogenetics and Evolution 70，171-181），根据它们明显不同的生殖解剖学将两个属同分为异名。
ABSTRACT By employing comparative morphology and anatomy as well as mitochondrial phylogenetics, we have identified three species of Landouria Godwin-Austen, 1918 in Timor-Leste. One of these species is identified as L. cf winteriana (Pfeiffer, 1842), a species originally described from Java, but considered widespread throughout the Indonesian archipelago. The two other species are newly described as L. timorensis n. sp. and L. montana n. sp., respectively. Landouria timorensis n. sp. is similar to L. winteriana, but differs by a smaller shell and details of its penial morphology. Landouria montana n. sp. is only found at higher altitudes and is readily distinguishable by its distinctive shell. A mitochondrial phylogeny reveals L. omphalostoma from Yunnan as the sister lineage of all Sunda Islands species. Based on this observation, we maintain the systematic placement of the Sunda Islands species in Landouria despite some minor differences in their genital anatomy. Furthermore, our phylogeny demonstrates that the East Asian genus Aegista Albers, 1850 is the probable sister taxon of Landouria. However, we reject the proposal by Hirano et al. ([2014] Substantial incongruence among the morphology, taxonomy, and molecular phylogeny of the land snails Aegista, Landouria, Trishoplita, and Pseudobuliminus (Pulmonata: Bradybaenidae) occurring in East Asia. Molecular Phylogenetics and Evolution 70, 171–181) to synonymise both genera based on their markedly distinct reproductive anatomy.
