Abstract
Five specimens of encysted trematode metacercariae of Pygidiopsis Looss, 1907, located outside the tissues of the host, in a free state, were found in the extrapaleal cavity of the gastropod mollusc Hydrobia acuta (Draparnaud, 1805) from Cossack Bay (Black Sea). A figure, an image, and measurements of excisted larvae were given.
