title: The first modern morphological description of <i>Cercaria pennata</i> and molecular evidence of its synonymy with <i>Pronoprymna ventricosa</i> in the Black Sea
abstract: During the parasitological examination of molluscs <i>Abra segmentum</i> obtained from the Black Sea basin, parthenitae belonging to the family Faustulidae were found. The cercariae were obtained by natural emergence and were studied using differential interference contrast microscopy and scanning electron microscopy. Specimens resemble <i>Cercaria pennata</i> ex <i>Tapes rugatus</i> which was described from the Sevastopol area, in the shape and length of the body, tail length, location and shap
