The Life Cycle of Crassiphiala bulboglossa (Trematoda: Strgeida): Development of the Metacercaria and Cyst, and Effect on the Fish Hosts
Date of this Version
The adult of Crassiphiala bulboglossa was described by Van Haitsma (1925) from the kingfisher, Ceryle alcycon. It can be differentiated from Uvulifer ambloplitis (Hughes, 1927), apparently its closest relative in North America, by the presence of a large bulbous holdfast occupying most of a cup-shaped forebody, and the absence of a ventral sucker. In U. ambloplitis the holdfast is small, the forebody is not cupped, and a ventral sucker is present. These species can be readily identified with the keys given by Dubois (1953).
