title: [Ultrastructural characteristics of the simple eyes of the louse Pediculus humanus corporis].
abstract: The simple eye of the human louse consists of two apparatuses: dioptric and light sensitive. The dioptric apparatus contains only a biconvex lens, which represents local thickening of the cuticle. The eye lacks the crystal cone (Semper cells) and special pigment cells. The light sensitive part of the eye contains about 130 photoreceptor cells. Each photoreceptor has rhabdomere which consists of numerous microvilli. The pigment granules are located only in the photoreceptor cells.
