Abstract

The minute valvatiform-shelled Hydrobiidae are less studied than other hydrobiid gastropods. In this paper, new data on these snails are presented, which have been collected at twelve springs in southern Greece: one in Boeotia, one on Evvoia Island, and ten on the Peloponnese Peninsula. Mitochondrial cytochrome oxidase subunit I (COI) and nuclear histone (H3) have been used to confirm the determinations and infer the relationships of the studied gastropods. They represent the generaDaphniola,GraecoarganiellaandIsimerope. New localities, expanding the known geographic ranges, have been presented forDaphniola hadeiandDaphniola louisi. A species ofDaphniolafound at two localities has been identified as a species new to science, and its description, including the shell, penis, and female reproductive organs is given. Possible relationships betweenGraecoarganiellaandIsimeropeare discussed; their representatives are possibly new species. At one locality a single specimen likely represents a new genus: it was found to be most closely related withIslamia, but genetically (p-distance) too distant to be congeneric withIslamia.
