During parasitological investigations of perch P. fluviatilis L., in spring 1988 from waters of Szczecin Firth, noticed a presence of Henneguya wolinensis n. sp. (Myxosporea: Bivalvulida) cysts on fish skin. Milk-white, oval cysts measured from 0.5 to 1.0 mm occurred under scales, on epidermis of all fish scaled body surface. Dimensions of spore: body length 22.3-27.2 μm, total length 61.1-69.3 μm, breadth 7.4-8.7 μm, polar capsules length 11.1-15.1 μm, polar filaments length 120-160 μm. The new described species compared with H. creplini and H. psorospermica from gills founding on perch together with H. wolinensis n. sp.
