Abstract

Three species of the genus Belgrandiella A. J. Wagner, 1928 and Boleana umbilicata (Kuščer, 1932) from springs in Slovenia and Croatia were used for this study. All of them were originally described based on minor differences in shell morphology. Molecular data showed only small differences among all the nominal taxa, typical of intrapopulation variation. COI sequences of Boleana umbilicata and Belgrandiella kusceri were identical, and Boleana should be synonymised with Belgrandiella. The molecular data strongly suggest that all four nominal species represent one biological entity – a genetically variable species.

Key words
