Scanning electron microscope observations on corrigia vitta [Dujardin, 1845] Shtrom, 1940 [trematoda: dicrocoeliidae]

ABSTRACT

The surface topography of the digenetic trematode Corrigia vitta was described by scanning electron microscope. It revealed the presence of several small sensory papillae on the oral sucker, ventral sucker and along the ventral surface of fluke. Several tegumental projections [spines or tubercles] cover the whole tegument, which vary in shape and length in different areas of the body, and several small invaginations [tegumental pores] are present allover the surface. The eggs are operculated at one pole and possess a smooth surface
