Abstract:
The present report is concerned with the surface structure of the metacercaria of Pa-ragonimus iloktsuenensis as visualized with the scanning electron microscopy. The meta-cercariae were obtained from the liver of tne Sesarma dehaani collected in Yingkou county, Liaoning Province.The tegumental spines of the metacercaria are single-pointed and densely distributed over the entire body and are slightly different in size and shape in different parts of the body. On the forebody of the ventral surface, a vertical ridgeline can be seen in the middle of the spines.In addition to the short spines, there are two circles of non-ciliated papillae on both lips of the oral and the ventral suckers. Around the oral sucker, there are 12 papillae on the outer circle and 6 on the inner circle; around the ventral sucker, there are 6 papillae on both the outer and inner circles. No sensory papillae were found around the ventral sucker. On each side of the anterior part of the ventral side, 8 to 10 pairs of papillae are arranged in two rows.
