252 COMPARATIVE PARASITOLOGY, <strong>68</strong>(2), JULY <strong>2001</strong> Figures 6-10. Preadult and adult of Lobatostoma jungwirthi. 6. Frontal view of the preadult showing the 5 oral lobules. 7. Posterior surface of the oral lobules showing monociliate papillae (arrow) and domeshaped papillae arranged without defined pattern. 8. Neck region (ventral) with pores (white arrow) (in some cases with secretion) and dome-shaped papillae. 9. General ventral view of the adult. A clear differentiation of the longitudinal septum of the ventral adhesive disc cannot be observed. 10. Anterior end of the ventral adhesive disc showing dome-shaped and monociliate papillae (arrow) on the edge of the walls. Scales: 6 = 50 u,m; 7, 8 = 10 u,m; 9 = 25 u,m; 10 = 100 u,m. also were distributed on the borders between the alveoli of the adhesive disc of both juvenile and adult worms. Nonciliate sensory receptors were found by Rohde and Watson (1990b) in the external ventral tegument of the ventral suckerlets in M. purvisi. This structure may correspond to the nonciliate disc-shaped receptors or to the Copyright © 2011, The Helminthological Society of Washington nonciliate type with a long root described by Rohde and Watson (1992) in the larva of L. manteri. Nonciliate tegumental receptors were also found in the juvenile of Astramphilina elongata Johnston, 1931 (Monogenea) (Rohde and Watson, 1990a). A SINGLE MULTICILIATE RECEPTOR: This Was
PAOLA AND DAMBORENEA—TEGUMENT OF LOBATOSTOMA JUNGWIRTHI 253 Figures 11-14. Ventral adhesive disc of adult Lobatostoma jungwirthi. 11. General view of the marginal alveoli on the marginal region at midbody level of the ventral adhesive disc. 12. Walls of the marginal alveoli showing 2 circles of dome-shaped papillae (arrow) and marginal gland pore. 13. Detail of the internal wall with almost 1 complete circle of monociliate papillae (arrows). 14. Ventral view: transverse septum with monociliate (black arrow) and nonciliate papillae (white arrow). Scales: 11 = 50 u,m; 12 = 25 u,m; 13, 14 = 10 jrni. observed in the posterior third of the dorsal region of the adult of L. jungwirthi. Paired multiciliate receptor complexes with 10 short cilia were described by Rohde and Watson (1990d) to be located dorsally to the mouth cavity of larval M. purvisi, but our record is the first of a surface multiciliate receptor in aspidogastreans. However, multiciliate receptors are found in other groups of parasitic Platyhelminthes, i.e., in the taste organ of the buccal complex of Pricea tnultae Chauhan, 1945 (Monogenea, Gastrocotylidae). Rohde and Watson (1996) found these receptors concentrated in small pits. Additionally, multiciliate pit-receptors were observed in the buccal complex of Polylabroides australis (Rohde and Watson, 1995b) and in specimens of an undescribed species of Proseriata (Monocelididae: Minonidae) (Rohde and Watson, 1995a). Pores of the marginal bodies were observed on the external border between the marginal alveoli of juveniles and adults of L. jungwirthi. Kritscher (1974) found similar structures in the adult of the species. These pores were described as part of a glandular system in the adhesive disc of aspidogastrids (Rohde, 1994). Unlike the preadult, the youngest juvenile does not have oral lobules. A few less-developed alveoli were observed on the ventral adhesive disc. Two sensory receptors were found in the preadult of L. jungwirthi'. a ciliate receptor with a cilium of intermediate length, and a nonciliate dome-shaped receptor.
