Members of the family Truncatellidae Gray, 1840 are widely distributed globally, but their presence in India is unclear. So far, only one species Truncatella guerinii A. Villa & J. B. Villa, 1841 has been reported from the Andaman and Nicobar Islands, but most malacologists were unsure of its occurrence due to the lack of appropriate descriptions and proper identification. In this paper, we confirm its presence in the Andaman Islands and also in Pondicherry in Indian waters. In addition, its natural history, distribution and the detailed taxonomy of the species is discussed.

关于Truncatella guerinii A.Villa和JB Villa的分类学注释，印度，1841年（软体动物：Littorinimorpha：Truncatellidae）

Truncatellidae Gray家族，1840年的成员遍布全球，但在印度的存在尚不清楚。迄今为止，安达曼和尼科巴群岛仅报告了1841年的Truncatella guerinii A. Villa和JB Villa，但由于缺乏适当的描述和适当的鉴定，大多数哺乳动物学家不确定它的发生。在本文中，我们确认了它在安达曼群岛和印度洋朋迪榭里的存在。此外，还讨论了其自然历史，分布以及该物种的详细分类学。
