The diversity and distribution of freshwater molluscs is poorly studied in the Republic of Georgia, due to the scarcity of field studies during the last 50 years. Here, we present the results of the first concerted investigation of freshwater mollusc biodiversity in the Javakheti Highlands, in the southern, mountainous region of Georgia. In total, we were able to collect 22 species from 42 sampling localities, including different kinds of freshwater habitats. Amongst the 22 collected species, 12 were recorded for the first time from Javakheti. From the newly-recorded species, Bathyomphalus contortus is a new country record, whose identity is supported by 16S rRNA sequence data.

Javakheti Highlands（格鲁吉亚共和国）淡水软体动物的物种多样性和分布

由于过去 50 年来缺乏实地研究，格鲁吉亚共和国对淡水软体动物的多样性和分布的研究很少。在这里，我们展示了对佐治亚州南部山区 Javakheti 高地淡水软体动物生物多样性的首次协调调查的结果。总共，我们能够从 42 个采样地点收集 22 个物种，包括不同种类的淡水栖息地。在收集到的 22 种物种中，有 12 种是首次从 Javakheti 记录到的。从新记录的物种来看，Bathyomphalus contortus 是一项新的国家记录，其身份得到了 16S rRNA 序列数据的支持。
