Abstract

The elytral striations of species belonging to the main groups of Hydraena s.l. are compared and some taxonomic conclusions are drawn from this study. The homologies of the male abdominal sterna and of the different parts of the aedeagus are discussed. Subgeneric and specific characters are described and illustrated for the five species of the western Palearctic taxon Phothydraena.
