PROSOLECITHUS-DANUBICA N-SP (DIGENEA, DICROCOELIIDAE) - A NEW DIGENEAN FROM SHREWS ON ISLANDS OF THE DANUBE DELTA

The helminth fauna of insectivores of the Danube delta has not been st udied before. Our investigation was carried our in both Ukrainian and Romanian ports of the delta. As a result, 33 helminth species from fiv e species of insectivores were found, including a new dicrocoeliid dig enean species, Prosolecithus danubica, from the liver of Sorer araneus and Neomys anomalus. Prosolecithus includes one other species, P, pel lucidus (Pojmanska, 1957), originally described as Dicrocoelium pelluc idum, from which P. danubica differs in sucker-ratio, configuration of vitelline fields and egg-size. An illustrated description of the new species and a generic diagnosis ore included and comments are mode on its morphological variability, site, distribution in the delta and pat hogenicity.
