Namely, the posterior type has lesions around the papilla and/or within the vascular arcade (posterior pole), but not in the peripheral area. Each papilla consists of 2 morphologically distinct regions. Hypothetically, glandular secretions are involved in tissue degradation (disintegration of the papilla and attached sucker following pairing) and fusion of the adjacent tegument. Cervical papillae situated at margin of cephalic and cervical regions. No evidence has been observed in this study that the contents of the pear-shaped cells are released through the tegument of the papillae. It is possible that there are two other types of papillae.

There are two small papillae on each side of the clypeus. The morphology associated with the multiple optic papillae and retinal ganglion cell distribution. Very strong immunoreactivity and staining in the region of the dorsal papilla was found for all 3 neuronal mediators examined. Through a twisting of the two bodies, the free sucker of one individual embraces the free papilla of its mate. The same 3 types of cell inclusions were observed and, as in the papillae, no ducts were seen connecting the cells to the tegument surface. The dorsal papilla failed to give a positive reaction with phalloidin, suggesting it is not muscular. The cuticle is covered with minute, close-set papillae, and bears numerous setae, approximately 0-02 mm. in length, on both dorsal and ventral surfaces. There are three types of papillae identifiable on the cercariae. Each of the pear-shaped cells of a papilla contains a nucleus, usually situated in the bulbous part of the cell. Cervical papillae cylindrical, rounded at outer margin with a central, needle-like projection. The papilla contains secretory cells, the ducts of which open onto the surface. Special attention has been paid to the reactivity of the papilla and the sucker of diporpa/juvenile stages. Unlike the ventral surface, the posterior end of the dorsal surface has only a small number of papillae. Anterior to the mandibles are a pair of nippleshaped papillae.
