Abstract:
The fine structure of the integumentary glands and mechanoreceptory setae in Dermacentor marginatus nymphs is described. The integumentary gland is localized in the epidermal layer and secretory products pass through the duct lumen and two cuticular lips to the surface. Ultrastructure of cuticular cavity represents triangular form with lateral folds. The mechanoreceptor setae are composed of glandular cells localized in the epidermal layer and cuticular setae movably articulated to the cuticle by means of a compact fibrillar ring around the base.
