Abstract: The first record of a valvatiform hydrobiid species in Hungary is presented. Hauffenia kissdalmae sp. n. is the eleventh species assigned to the genus and is differentiated from all known congeners. Distinguishing characters are the pegless operculum, the almost flat spire, the short, flat penis with a wide lateral lobe on the left side and a less evident one on the right, and female genitalia with a very small seminal receptacle, arising from the posterior-most point of the renal oviduct. The zoogeographic corollary of this discovery is that the distribution of the genus is now extended eastward and thus it nearly reaches the range of a large group of valvatiform and still unidentified Hauffenia(?) forms found in several localities in Slovakia and in a cave spring in north-eastern Hungary. Other species of the genus Hauffenia live in subterranean, running or interstitial water and karst spring, always in complete darkness. On the contrary, several living specimens of this new species were found in small and shallow spring on volcanic bedrock in the Börzsöny Mountain. For assessment of rarity and conservation status of the species further data from nearby localities are needed.
