FIGURE 2. Scanning electron micrographs of the sensilla. A, B, ventral view of the anterior sucker showing two rings of sensilla (arrows), the external one with smaller sensilla. C, structure of a mouth sensillum showing a central overhead region delimited by a surrounding rime (sr) with cilia (c). D, particular of the anterior sucker showing numerous pores (arrows) beneath the rings of sensilla. E, ventral surface of the body showing regular pattern of sensilla (arrows) disposed in rows and alternate with pores. F, structure of a body sensillum showing short grouped cilia (g) and long single cilia (s) in the proximity of a pore.
