There are a total of 47 species from ten families of Gastropoda recorded on Bacan Island from 1861 to 1963 by 15 studies. In 2022, the island was revisited to investigate its current land snail diversity. Our survey yielded 555 individuals, which were identified and classified into 27 species from eleven families. Among these, nine species were newly recorded on Bacan Island, bringing the total number of known land snail species to 56. These new records include a new species, Nurinsiyah, Prasetia, Mujiono & Heryanto, The most abundant species collected was (family Trochomorphidae). Differences in sampling locations and the extent of forest habitats in the surveyed areas may account for the different number of recorded species from previous and recent studies. Comprehensive systematic and standardised surveys are crucial for ensuring sampling completeness to further assess species endemism and biogeographic patterns. Furthermore, cataloguing all known species and resolving land snail's systematics with integrative approach are important to understand the true diversity of land snail in this region.
1861年至1963年间,15项研究记录了巴坎岛上总共47种来自腹足纲十个科的物种。2022年,对该岛进行了再次考察,以调查其当前的陆地蜗牛多样性。我们的调查共获得了555个个体,经鉴定并归类为来自11个科的27个物种。其中,有9个物种是在巴坎岛首次记录,使已知陆地蜗牛物种总数达到56种。这些新记录包括一个新物种,即努林西亚蜗牛(Nurinsiyah, Prasetia, Mujiono & Heryanto),采集到的数量最多的物种是(陀螺螺科)。采样地点的差异以及调查区域内森林栖息地的范围可能是导致先前和近期研究中记录物种数量不同的原因。全面系统且标准化的调查对于确保采样完整性以进一步评估物种特有性和生物地理模式至关重要。此外,对所有已知物种进行编目并采用综合方法解决陆地蜗牛的系统分类问题,对于了解该地区陆地蜗牛的真正多样性很重要。
