SEM micrographs herein help to accurately define the above surface topographical features by adding a more adequate 3-D picture to the original descriptions of both parasitic species. In <i>A. brevispiculata</i> the entire body cuticle structure, well-differentiated paracloacal papillae and the wrinkle cuticle of the papillae are clear examples that enhance the above differentiation of structures as seen by LM or SEM. Similarly, in <i>P. ceticola</i> the cuticle striations, bulky cloacal lips, rectangular distribution pattern of distal papillae and the absence of a groove separating paracloacal papillae which are obliquely arranged are all different to those features previously described.
