SENSORY ENDINGS IN DIPLOSTOMUM-PSEUDOSPATHACEUM NIEWIADOMSKA, 1984 CERCARIAE (DIGENEA, DIPLOSTOMIDAE)

The chaetotaxy pattern of D. pseudospathaceum related to the structure of the nervous system (in the cephalic and preacetabular region) was described based upon LM and TEM investigations. The proper location of thirteen different ultrastructural types of sensory endings (SE) will be described by Czubaj and Niewiadomska (in press) were established, It was shown that: the cercarial body, tail stem and furcae have a spe cific set of SE, and that several types of SE may be localized in diff erent part of the cercaria. The location of particular sensory endings in the rings of the cephalic, pre- and postacetabular regions, tail s tem and furcae was ascertained.
