Prosolecithus danubica n.sp. (Digenea: Dicrocoeliidae) a new digenean from shrews on islands of the Danube delta

摘要

The helminth fauna of insectivores of the Danube delta has not been studied before. Our investigation was carried out in both Ukrainian and Romanian parts of the delta. As a result, 33 helminth species from five species of insectivores were found, including a new dicrocoeliid digenean species, Prosolecithus danubica, from the liver of Sorex araneus and Neomys anomalus. Prosolecithus includes one other species, P. pellucidus (Pojmánska, 1957), originally described as Dicrocoelium pellucidum, 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 are included and comments are made on its morphological variability, site, distribution in the delta and pathogenicity.
