REVISION OF 'HAUFFENIA JADERTINA' KUSCER 1933, AND DESCRIPTION OF A NEW SPECIES FROM PAG ISLAND, CROATIA (GASTROPODA: HYDROBIIDAE)

摘要

Hauffenia jadertina Kuscer 1933, is revised using material from the type localities and others from Croatia, mostly from the Cetina valley. On the basis of anatomical characters it is attributed to the genus Kerkia Radoman 1978. Hauffenia jadertina sinjana Kuscer 1933, is synonymized with Kerkia jadertina. A new species, attributed to the same genus, Kerkia kareli n. sp., is described from Pag Island in the northern Adriatic Sea (Croatia). It inhabits phreatic waters and, until now, it has been collected only in three wells situated on the island. In this paper, a detailed description of the two species is given.
