title: Scanning electron microscope study of mature and immature worms of a Sanguinicola sp. (Digenea: Sanguinicolidae).
abstract: A study was made of the morphological details of the tegument of mature (40-42 days) and immature (28 days) Sanguinicola sp. found in cyprinids of certain rivers of the province of Salamanca (Spain). In the adult worms, the entire tegument was covered with microvilli; the parasite showed various kinds of sensory organs, whose distribution is specified here. The lateral margins revealed strong denticules (except the anterior and posterior extremities) with spines and bristles. The immature worms showed a far simpler external structure; they lacked microvilli but did show orifices which could be sensory organelles. The lateral margins only showed the presence of spines.
