FIGURES 1–10 in Macrobothriotaenia ficta (Cestoda: Proteocephalidea), a parasite of sunbeam snake (Xenopeltis unicolor): example of convergent evolution

FIGURES 1–10. Macrobothriotaenia ficta (Meggitt, 1931) from Xenopeltis unicolor. Scanning electron micrographs. 1. Scolex, apical view. 2. Scolex, lateral view. 3. Detail of a sucker, apical view. 4. Lower part of the exterior surface of a sucker. 5. Capilliform filitriches at level of the apex surface. 6. Capilliform filitriches at the upper marginal surface of a sucker. 7. Luminal surface of suckers covered with capilliform filitriches and few gladiate spinitriches. 8. Non-adherent surface of suckers covered with long capilliform filitriches and few gladiate spinitriches. 9, 10. Posterior part of suckers and proliferation zone covered with long gladiate spinitriches. Note: small black numbers correspond to the figures showing higher magnification images of these surfaces.
