REDESCRIPTION OF THE DIGENETIC TREMATODES LEPIDAPEDON CALLI AND L. PUGETENSIS ACENA, AND NEW HOST RECORDS FOR L. CALLI AND EURYCREADIUM VITELLOSUM MANTER FROM FISHES OF WASHINGTON STATE

Abstract

Lepidapedon calli Acena, 1947 and L. pugetensis Acena, 1947 are redescribed from types and paratypes and from additional specimens of L. calli collected at Friday Harbor, Washington, U.S.A. L. pugetensis is synonymized with L. elongatum (Lebour, 1908) Nicoll, 1915. The pleuronectid fish Microstomus pacificus is a newly reported host for L. calli and for Eurycreadium vitellosum Manter, 1934. Steringotrema (Rhodotrema) quinquelobata. Layman, 1930 is transferred to the genus Eurycreadium, becoming E. quinquelobata (Layman, 1930), because of its tubelike excretory bladder, extensive vitellaria, and type of cirrus sac.
